emulators/free42: update to version 3.0.13

2022-06-16: release 3.0.13

* Fixed handling of invalid number keys in BINM and OCTM modes.
* Windows and Linux versions: Fixed handling of non-ASCII separator characters.

2022-06-14: release 3.0.12

* Localized Copy & Paste.
* More accurate complex ACOS and ACOSH.
* SOLVE now handles functions that are always positive or always negative a bit
  better, reporting Extremum when the iteration appears to be bouncing around
  without improving, instead of continuing indefinitely.
* Added XVIEW function. This works like AVIEW, except it takes the string from
  the X register instead of ALPHA, so it avoids the 44-character length limit.
* Android version: Now removes itself from the task list if exited using OFF.

2022-05-05: release 3.0.11a (Windows and Linux)

* More efficient display updating, so long-running programs that update the
  display a lot don't waste a lot of CPU time repainting the display faster
  than the human eye can see, and spend more time actually running the program
  instead. Note that this update is for Windows and Linux only, because the
  Android, iOS, and MacOS versions already worked this way.

2022-05-01: release 3.0.11

* Implemented LCLV: CLV for local variables only. The regular CLV now works on
  global variables only.
* RND in ALL mode now rounds like in SCI 11, instead of doing nothing.
* HEAD, when applied to a string in a numbered register, would corrupt the
  string if it was 16 characters long before the call (8 characters in the
  binary version). Fixed.
* Y^X accuracy improvements with integer X.
* Fixed DUPN 2 in 4STK mode. It used to duplicate X into T and Y into Z.
  DUPN in NSTK mode was not affected by this bug.
* Added WIDTH and HEIGHT functions. These always return 131 and 16,
  respectively; this may not seem very useful, but can be used in programs that
  are meant to work in both Free42 and Plus42, to allow them to take advantage
  of the larger display when running in Plus42.
* L4STK didn't pad the stack to 4 levels when used without FUNC. Fixed.
* Binary version: ROTXY and DATE+ rounded toward negative infinity instead of
  rounding toward zero. Fixed.
* Windows version: comes in 64-bit and 32-bit versions now.
* Windows and Linux versions: Now support fractional display scaling.

2022-01-27: release 3.0.10

* Added ãæíIST, LISTãæ SKIP, CPXMAT?, and TYPE? functions, and changed the name
  of PRMVAR to PGMVAR. See the Free42 web site for details.
* INPUT caused incorrect printer output in NORM and TRACE modes. Fixed.
* Escape sequences for undefined characters in Copy and Paste and printer
  output.
* When the Y register contains a string or list, in RUN mode, the + key now
  performs APPEND.

2021-12-29: release 3.0.9a (Windows only)

* Fixed crash when launching without state

2021-12-26: release 3.0.9

* Fixed handling of single-character strings in programs.
  This was broken in the previous release.

2021-12-23: release 3.0.8

* Auto-repeat for XSTR, and ALPHA arguments in general.
* Windows, MacOS, and Linux versions: Keyboard mapping for CursorLeft to ãæ
  Shift-CursorLeft to <ãæand ãæ CursorRight to ãæ Shift-CursorRight to ãæ and
  ãæ and Delete to DEL, in menus.
* Android version: Fixed blurry print-out on certain devices.

2021-11-07: release 3.0.7

* A2LINE now handles strings that start with characters 127-255 in a more
  sensible manner. Also, added A2+LINE function for generating appended
  strings, since the old trick of using a string starting with character 127 no
  longer works.
* More accurate complex TAN and TANH.
* RND did not handle large numbers correctly, failing to round off as many
  digits as necessary in certain cases. Fixed.
* Σ+ and Σ- always wanted two arguments, even in NSTK mode, when X contained a
  real matrix. Fixed.
* Copy and Paste now handle list objects.

2021-07-27: release 3.0.6

* Added string and list functions. See the Free42 web site for details.
* Added lowercase letters to the menu font.

2021-07-01: release 3.0.5

* L4STK could crash, due to an incorrect LNSTK fix in 3.0.2. Fixed.
* Fixed a couple of skin macro bugs: Failure to start program execution when
  EXIT was pressed during VARMNU1, and UI freeze when starting program
  execution in some cases.

2021-06-10: release 3.0.4

* Fixed bug in complex LU decomposition, which could lead to incorrect results
  in INVRT, DET, and matrix division with complex matrices.
* FUNC and RTN now save and restore ERRMSG and ERRNO along with flag 25.
* Added RCOMPLX and PCOMPLX functions. These work like COMPLEX, except they
  ignore flag 73 (POLAR mode) and instead always assume rectangular or polar
  mode, respectively.
  Also modified X2LINE so it uses RCOMPLX instead of COMPLEX when generating
  program lines for complex numbers, so the generated code is correct
  regardless of RECT/POLAR mode.
* MENU and VARMNU1 tweaks: The programmable menu is now cancelled whenever an
  operation is performed that clears the RTN stack, such as BST, or GTO in RUN
  mode. And in VARMNU1, don't trap EXIT when the menu was activated in RUN
  mode, or when an operation was performed that cleared the RTN stack.
* Binary version: Fixed WSIZE to allow word size of 53.
* Paste fixes: In PRGM and ALPHA modes, Paste now clears any messages that may
  have been left in the display from previous operations. (In RUN mode, this
  was already the case.) Also, Paste now sets flag 22 when pasting real or
  complex scalars into X, and sets flag 23 when pasting in ALPHA mode.

2021-04-28: release 3.0.3

* Implemented VARMNU1. This is a variation on VARMENU, with two differences: It
  allows selecting a variable without having to press its menu button twice;
  and it catches EXIT, performing CLA RUN when it is pressed.
* Implemented X2LINE and A2LINE functions. These non-programmable functions
  create program lines containing the current contents of the X or ALPHA
  registers, respectively.
* When INDEX or EDITN are performed on a local matrix, while another matrix is
  already indexed, the IJ pointers are saved, and restored when the current
  function returns.
* RTNERR now accepts a string instead of a numeric argument, so functions can
  raise error messages other than the eight standard ones.
* Implemented ERRNO and ERRMSG functions. These return the error number and
  error message, respectively, for the last error caught by flag 25.
* Implemented XSTR function, for creating strings directly in the X register.
* Fixed memory leak in the parameterized comparison functions.

2021-03-29: release 3.0.2

* Fixed possible stack corruption or crash due to LNSTK, when big stack mode is
  already active.
* Fixed DROPN crash in 4STK mode.
* Fixed matrix editor's GOTO Row/Column when stack empty (big stack mode).
* Fixed bounds check bug in AGRAPH. This could cause nothing to be drawn when
  the pattern was one pixel from being entirely off-screen.
* Android version: Fixed filesystem access in Android 10.

2021-03-04: release 3.0.1

* Implemented a work-around for a bug in the decimal floating-point library
  that could cause inaccurate results for several complex functions.
* Implemented PRMVAR function. This prints all the variables associated with
  the given LBL through MVAR declarations.
* Implemented new comparison functions, for comparing arbitrary arguments to X
  or to zero: X=?, X<?, 0=?, etc.
* Added error number 8 to RTNERR, to allow user-defined functions to raise the
  Too Few Arguments error condition.
* RTN from the keyboard, and other actions that cause the RTN stack to be
  cleared, now restore the stack mode if it had been changed locally using
  LNSTK or L4STK.
* Windows version: Fixed a bug that could cause programs with many ALPHA labels
  to show up as blank lines in the Export Programs dialog.

2021-02-22: release 3.0

* Added dynamic stack option. See the Free42 web site for details.
* Added the date and time format options to the MODES menu.
* Changed the RTNERR function to take the error number from a parameter, rather
  than from the X register. To prevent existing programs using the old
  parameter-less RTNERR from breaking, those RTNERRs are converted to the
  equivalent new instruction, RTNERR IND ST X.
* Added PGMMENU function. This shows a menu of ALPHA labels with MVAR
  instructions, like the top-level menu presented by SOLVER and «æ(x). It is
  meant to be used by programs that aim to implement a similar behavior as
  those built-in menus.
* On cold start, now setting the date and time format accordig to the host
  operating system's locale settings.
* The Free42 extensions to the HP-42S instruction set are now shown in separate
  sections in CATALOG, rather than at the end of the FCN catalog.
* Added STRACE option to PRINT menu. This is the "Stack trace" option, i.e.
  TRACE mode where the entire stack gets printed, not just X. The option itself
  is not new, it was implemented in 2.5.21, but the STRACE function, that
  allows you to set that mode without having to twiddle flags, is new.

2021-02-02: release 2.5.25

* Fixed pasting of zero. This was broken in 2.5.21.

2021-01-17: release 2.5.24a (Android only)

* Fixed screen rotation issue with Android 11.

2021-01-13: release 2.5.24

* Improved user-defined function support. The changes are rather substantial;
  please check the Free42 web site for details.
* The previous release introduced a bug when pasting a program without line
  numbers, causing numbers to be mangled. Fixed.

2021-01-06: release 2.5.23

* Implemented support for user-defined function semantics: stack preservation,
  RTN with skip, RTN with error. See the Free42 web site for details.
* Better handling of number lines: the visual difference between equivalent
  representations of a number is now preserved, so 1000 stays 1000 and is not
  turned into 1E3, and numbers that are out of range for the current platform
  now cause an error message instead of being silently turned into the maximum
  representable number or zero.
* Implemented FMA (Fused Multiply-Add). This simply exposes the underlying FMA
  function provided by the floating-point hardware or libraries.
* In programs, now handles pasting FIX/SCI/ENG with 1-digit argument, for HP-41
  compatibility.

2020-11-24: release 2.5.22a (Android only)

* The previous release was crashing on a lot of devices; apparently the NDK
  version I used to build it, r21b, is incompatible with certain older devices.
  Going back to r19c for now.

2020-11-23: release 2.5.22

* Minor UI fixes and improvements: 'Close' menu item (Mac), Copy and Paste in
  dialogs (Mac), Unicode support in file names (Windows), and pre-populating
  file names in file selection dialogs (all versions).
* Implemented LASTO. This is related to LSTO like ASTO is related to STO.
* Implemented No-Operation (NOP) function. This function does nothing, as its
  name suggests, and can be useful when using ISG for counting without an upper
  bound, for instance. The function is encoded using the 0xF0 opcode, which is
  sometimes used on the HP-41 for the same purpose.
* On the real HP-42S, GETKEY halts program execution when R/S, EXIT, or Shift-
  EXIT are pressed. In Free42, however, Shift-EXIT did not cause program
  execution to halt. Fixed.
* Implemented GETKEY1 function. This works like the regular GETKEY, except it
  only halts on R/S, allowing programs to implement custom behaviors for EXIT
  and Shift-EXIT.
* STOFLAG didn't update the G and RAD annunciators when flags 42 or 43 were
  changed. Fixed.
* Implemented range option for STOFLAG: with the flags in Y and a number bb.ee
  in X, only flags bb through ee are restored, while the others are untouched.
  If ee is zero, only flag bb is restored. This mode of operation exists in the
  HP-41 Extended Functions module and in the HP-41CX, but was missing in the
  Free42 implementation.
* Binary version: Changed maximum WSIZE from 52 to 53.
* MacOS version: Building universal binary now, with Intel and ARM (Apple
  Silicon) support.
* iOS version: Fixed crash when saving print-out using Share -> Save Image.

2020-10-24: release 2.5.21

* Implemented ANUM, X<>F, RCLFLAG, and STOFLAG functions. See the Free42 web
  site for details.
* Implemented "stack trace" mode: when flags 15 and 16 are both set, the
  printer prints in a variation of TRACE mode, printing not just X after every
  instruction, but the entire stack.
* Pasting long numbers could return incorrect results if many leading zeroes
  were present. Fixed.
* Real/complex and complex/complex division could return Not a Number for
  certain inputs, e.g. 1e3200 ENTER COMPLEX ENTER /. Fixed. Also applied a
  similar fix to complex 1/X.
* Complex matrix division, INVRT, and DET would return incorrect results for
  large matrices (20x20 or greater). Fixed.

2020-09-20: release 2.5.20

* Fixed INTEG behavior when integrand returns non-real. It used to treat such
  results as zero while it should raise an error instead.
* Fixed DATE+, DDAYS, and DOW when flags 31 and 67 are both set.
  This combination of flags is never set by the DMY, MDY, and YMD functions,
  but it can happen when you execute YMD followed by SF 31.
* Fixed garbage in SHOW when BIN overflows to HEX.
* During TRACE, print blank line before LBL, like the HP-41.
* When ISG reached zero, the loop control variable would end up having the
  wrong sign. For example, -1.00001 ISG ST X => -0.00001, should be 0.00001.
  Fixed.
* Added [FIND], [MAX], and [MIN] to the FCN catalog. These are undocumented
  functions from the HP-42S that were previously not shown in the catalog, even
  though they did work.
* COMB could return Out of Range in certain cases where the correct result was
  not, in fact, out of range. For example, 20408 ENTER 10204 COMB.
* ISG and DSE with a named variable would crash if that variable did not exist.
  Fixed.

2020-07-05: release 2.5.19

* Fixed stack lift behavior with GETKEY.

2020-04-11: release 2.5.18

* Fixed pasting of 1/X and 10^X without line number.
* Android version: Updated HEADING implementation so it works on phones that no
  longer provide the old compass API.
* iOS version: Fixed double-import, when loading Shared files.

2020-02-27: release 2.5.17b (Android only)

* Removing the n-key rollover and swipe-to-switch that were introduced in the
  previous release; 2.5.17a suffers from missed keystrokes and erratic swipe
  detection, caused by the new logic. Since I appear to be unable to do proper
  testing on these features with my own phone, I am scrapping them and have no
  plans to re-introduce them. (I am not removing them from the iOS version,
  since they appear to be working fine there.)

2020-02-22: release 2.5.17a (Android and iOS)

* Android version: Can now switch between the calculator and print-out by
  swiping sideways. This feature is experimental and may not work on all
  phones.
* Android version: Implemented n-key rollover.
* iOS version: Fixed initial print-out scroll position. Version 2.5.17
  introduced a bug where it would not scroll all the way to the bottom
  initially.

2020-02-13: release 2.5.17 (iOS, Windows, MacOS, and Linux)

* Fixed minor memory leak in Paste.
* iOS version: Implemented n-key rollover.
* iOS version: Fixed several minor bugs and inconsistencies in landscape mode.
* iOS and MacOS versions: Print-out now grows from the top down, rather than
  from the bottom up, to be consistent with these types of UIs in general, and
  specifically with Free42 on other platforms.

2020-02-08: release 2.5.16b (iOS only)

* Can now switch between the calculator and print-out by swiping sideways.

2020-02-02: release 2.5.16a (iOS only)

* Fixed file import from the Files app.

2020-01-25: release 2.5.16

* Fixed GETKEY behavior with skins that use direct command mapping.
* Fixed GETKEY behavior with physical keyboards in ALPHA mode.

2020-01-18: release 2.5.15

* Some fixes to Paste to improve compatibility with Emu42 text.
* Fixed Skin menu behavior: user-loaded skins now take priority over built-in
  ones, and built-in skins that are overridden by user-loaded ones are now
  shown grayed out in the menu.
* Linux version: Implemented XDG Base Directory Specification compliance:
  Moved Free42 directory from $HOME/.free42 to $XDG_DATA_HOME/free42, or
  $HOME/.local/share/free42 in case XDG_DATA_HOME is unset or empty.
  Also, now looking for skins in free42 and free42/shared under $XDG_DATA_DIRS,
  or under /usr/local/share:/usr/share if XDG_DATA_DIRS is unset or empty.
  Skins will also still be looked for in the Free42 directory.

2020-01-11: release 2.5.14

* Some fixes to Paste to improve compatibility with HP-41 text.

2020-01-11: release 2.5.13a (Linux only)

* Another thin-dark-line fix, this time for GDK_SCALE > 1 on certain platforms,
  including Raspbian 10.

2020-01-09: release 2.5.13

* When REGS was shared, ASTO nn could store the character data into the wrong
  copy of the matrix. Fixed.

2020-01-07: release 2.5.12c (Linux only)

* When the print-out area was still growing, i.e. hadn't reached its maximum
  height of 30,000 pixels yet, it was not being repainted in a timely manner.
  Bug introduced by the switch to GTK 3; did not affect early GTK 3 versions
  but became apparent in Ubuntu 18.04 and 19.10. Fixed.

2020-01-03: release 2.5.12b (Linux only)

* Made repaint logic more efficient, also making it work under Wayland.

2019-12-01: release 2.5.12a (Linux only)

* In scaled mode (GDK_SCALE greater than 1), bitmap smoothing causes drawing of
  the display bitmap to bleed outside the display rectangle, and this can lead
  to thin dark lines being left behind around the display, and that looks ugly.
  A similar problem exists in the Android version, and I implemented a similar
  fix here, namely, to always repaint the entire display when the core updates
  it, and to update a slightly larger rectangle than the display itself.
  Because this fix can cause programs to run slower on older systems, I added
  an option to Preferences to switch back to using the old logic.

2019-11-28: release 2.5.12 (Windows and Linux)

* Linux version: Switched from GTK 2 to 3, for HiDPI support.
* Windows and Linux versions: Removed the "Single Instance" option. Both now
  always run in Single Instance mode; what was removed was the possibility to
  turn *off* Single Instance and allow multiple instances to run concurrently.
  That never worked well, and in the Windows version, there was never any
  reason to allow it. In the GTK version, there was a reason, which was that
  Single Instance was hard to implement and did not work well in all
  environments; with GTK 3, Single Instance is supported by the platform, and
  there is no longer any reason not to use it.

2019-10-25: release 2.5.11

* Windows version: Program export in "raw" format performed LF-to-CRLF
  translation on the output file, turning XEQ 10 into XEQ 13 LBL 09, among
  other things. Bug introduced in 2.5.
* Decimal version: During number entry, if you backspaced over a negative
  number until only the minus sign remained, that minus would not be parsed
  correctly, and you could get <Not a Number>. For example, 1 +/- <- ENTER.

2019-10-11: release 2.5.10

* The index range check in R<>R was faulty, allowing a row index equal to the
  number of rows plus one to be used, which in turn would cause memory
  corruption. Fixed.
* Android version: When renaming the currently active state, the state name was
  not updated in the shell settings, with the result that upon exit, the state
  would still be saved under the old name, and at the next launch, would also
  be loaded under the old name. The net effect of all this was that instead of
  ending up with a renamed state, you'd end up with a copy.

2019-10-05: release 2.5.9b (Android and iOS)

* Android version: Could launch with the wrong screen orientation under certain
  circumstances. Fixed.
* iOS version: Greater range of key click volume levels.
* iOS version: Added sanity check for raw files imported using Copy to Free42.

2019-09-28: release 2.5.9a (Android only)

* Several changes in file handling. No longer associates itself with all files,
  so Free42 won't be offered to open files of any types other than raw and f42.
  Unfortunately, this also means that opening f42 files directly from email
  attachments no longer works; state files will now need to be downloaded, then
  opened using the file selection boxes, using More -> Import in the States
  view. Cumbersome, but it's the best I can do given Android's lack of file
  extension filtering for email attachments.
* Added a slider for the key click volume; now offers nine levels plus silence.
* Changed the haptic feedback slider to a logarithmic scale, adding a lot more
  resolution to the weaker end of the scale, for those with devices that are
  capable of it and fingers sensitive enough to feel it.

2019-09-21: release 2.5.9

* Importing programs would insert the programs at the current location, instead
  of at the end of memory. Bug introduced in 2.5 or one of the subsequent
  revisions. Now fixed.
* iOS version: Added support for Dark Mode in iOS 13.
* Android version: Added file extension filtering for file, http, and https URL
  schemes. This should make Free42 not appear in as many file selection
  contexts as before, without making it disappear from contexts where it should
  be offered as an option. N.B. File extension filtering is not supported with
  the content scheme, which means Free42 will still show up in all contexts
  where attachments are opened, and depending on the file manager used, also
  when opening files from file managers.

2019-09-20: release 2.5.8

* When loading a corrupted state file causes a crash, the state file is now
  renamed so that it won't be read again, and the app will start with Memory
  Clear the next time it is launched, instead of crashing again and again.
* Android and iOS versions: Fixed a couple of import-related crashes.

2019-09-16: release 2.5.7

* SOLVE did not always return the second-best guess in Y. Fixed.
* Android version: Changed haptic feedback preference setting from on/off
  switch to a four-level slider, for off/light/medium/heavy feedback.
* Android version: Reduced the GPS update interval for LOCAT from 60 seconds to
  5 seconds.
* Android version: Sharing an empty print-out would crash. Fixed; now it pops
  up a message instead.
* Android version: Fixed crashes in state file import activity: intents without
  data, and SecurityException and UnsupportedOperationException while trying to
  get attachment file names.
* iOS version: Changed haptic feedback preference setting from on/off switch to
  a four-level slider, for off/light/medium/heavy feedback. Also, changed key
  clicks setting from on/off switch to a three-way slider, for off/standard/wav
  click sounds, where standard is the old system key click sound, and wav is a
  wav file that sounds a bit louder.
* iOS version: Making the single-threaded logic permanent. The complexity of
  the multi-threaded event handling logic makes the code too hard to maintain,
  while the benefits in terms of performance are marginal. The only noticeable
  disadvantage of the single-threaded approach was poor performance in display-
  intensive code, and that was mitigated simply by repainting less
  aggressively.
* iOS version: Preferences view now expands to fill the width of the screen.
* MacOS version: Making the app single-threaded. This is the same change as in
  the iOS version; the aim is to simplify the code, making it more robust,
  while sacrificing very little in terms of performance.

2019-09-09: release 2.5.6a (iOS only)

* iOS version: Made the app single-threaded. Interim version, to deal with the
  mysterious crashes in [CalcView drawRect:].

2019-09-08: release 2.5.6

* SOLVE would not always return the best function value in Z. Fixed.
* iOS version: There have been crashes occurring in the display update logic,
  due to some not yet understood condition that appears to affect faster
  iPhones (8, X, XR, XS). I implemented a fix that appears to prevent these,
  but at a cost in terms of performance, i.e. the emulation is a bit slower
  now. I'm working on a proper fix, which will eliminate these problems and
  restore maximum performance.

2019-09-06: release 2.5.5

* Moved the settings "Singular Matrix Error," "Matrix Out Of Range," and "Auto-
  Repeat" from the core state (the *.f42 files) to the shell state, so they are
  not affected by switching core states.
* Fixed a bug that caused State File Corrupt when reading a state containing a
  zero-length string.
* iOS version: Fixed a couple of bugs that were causing memory and state file
  corruption and crashes.
* iOS and MacOS versions: Fixed a couple of bugs that were causing crashes in
  the States window.
* Android version: The States window would ask for confirmation to revert the
  current state back to the last version saved, even when the user was trying
  to switch to a different state. Fixed.

2019-09-02: release 2.5.4 (iOS only)

* Fixed a crash when the States window was opened the very first time the app
  was run after a new install.
* Fixed a bug that could cause the hostname lookup for the HTTP Server window
  to fail.

2019-09-01: release 2.5.3

* Invalid state files (corrupt, or created by an incompatible newer version of
  Free42) are now renamed, so they are not lost when a new state is written,
  and can be retrieved for post-mortem analysis.

2019-08-31: release 2.5.2

* In the States window, renamed Reload to Revert, and added a confirmation
  dialog, since that is a potentially destructive action.
* When programs were imported from raw files, empty programs were sometimes
  being created unnecessarily. Harmless but slightly annoying. Fixed.
* Android and iOS versions: Added "share" option for Print-Out view.
* Android and iOS versions: Added "share" option for programs in raw format.
* Android and iOS versions: Now import raw files directly from email
  attachments and web links.

2019-08-28: release 2.5.1

* Fixed bug in 2.5 that caused string elements in real matrices (including the
  numbered registers) to be written incorrectly in the state file, leading to
  memory corruption and crashes when the state file was read back in.
* iOS version: Now makes sure that the current state shows up in the list in
  the States view, even if it is opened right after a fresh install or right
  after upgrading from a version before 2.5.

2019-08-25: release 2.5

* Added state file manager, for loading, saving, and switching between,
  calculator states. The state files are in a platform-neutral format, so they
  can be exchanged between Free42 instances running on different devices.
* Fixed crash in RTN when a local variable was hiding the indexed matrix.

2019-07-12: release 2.4.2

* Windows version: The new Ctrl-A, Ctrl-I, and Ctrl-T shortcuts (Paper Advance,
  Copy Print-Out as Image, and Copy Print-Out as Text) didn't work, because I
  hadn't updated the corresponding accelerator resources. Fixed.
* Windows and Linux versions: All Ctrl-<Key> shortcuts now work even when the
  Print-Out window is on top.
* Android, iOS, and MacOS versions: When loading a skin in the skin browser,
  they now force an un-cached load, so skin fixes can actually be loaded by
  users without delay, and without having to resort to side-loading.
* Android and iOS versions: Changed default landscape skin, from desktop/42ct
  to android/SGS-L. The old skin had keys below the display that didn't line up
  with the menus; you really have to have Σ+ 1/x ÓÙ LOG LN XEQ
  below the display for a consistent user interface.
* iOS version: Changed Standard-X skin, from Ehrling42sl.X to Matt42X. The old
  skin was rather blurry; the new skin has nice and crisp text for all key
  labels.

2019-07-03: release 2.4.1

* Fixed several bugs in BWRAP mode.

2019-07-01: release 2.4

* Implemented configurable word size for BASE functions (up to 64 bits, or 52
  in Free42 Binary), unsigned mode, and wrap mode. The new settings are all in
  a new row in the MODES menu.
* Android, iOS, and MacOS versions: Added some feedback in the skin loading
  window: the "Load" button changes to "..." while a page load is in progress;
  "Load" is enabled only when a GIF or layout file is being displayed, i.e.
  something that could actually be a skin, and therefore loadable; and finally,
  when Load is pressed to load a skin, an alert box is now shown to report
  success or failure.

2019-06-25: release 2.3.1a (Android only)

* Adding -mfpu=vfp to compilation flags when building the Intel library for
  armv7. Apparently, with NDK r19c, Neon is enabled by default, but Neon is not
  supported on all armv7 Android devices, so this setting is causing 2.3.1 to
  crash on certain phones. (2.2.1b and earlier were built with r4b, which did
  not have this problem.)

2019-06-25: release 2.3.1

* Android version: Implemented the 2.3 features, with the exception of Copy
  Print-Out as Image. (Apparently Android doesn't support images on the
  clipboard.)
* MacOS version: Copy Print-Out as Image didn't handle wrap-around in the
  image buffer correctly. Fixed.
* Windows and Linux version: Implemented Paper Advance, Copy Print-Out as Text,
  and Copy Print-Out as Image.
* iOS version: Fixed the top-of-screen menu trigger so that it no longer
  sabotages keys that are also in that area, as in the HP_Mega_42 and SGS-L
  skins. This is the same fix I made for Android in release 1.5.8d. I didn't
  think to fix this for iOS at the time, probably because the iOS version
  didn't support landscape mode then.

2019-06-15: release 2.3.0a (iOS only)

* Added the 2.3 features.
  This should have been called version 2.3 as well, but a mistake with the
  release build forced me to use the next higher version number instead.

2019-06-12: release 2.3 (MacOS only)

* Added Load Skins feature, for downloading and installing skins from the
  Internet.
* Added Delete Skins feature.
* Added Paper Advance for Print-Out window.
* Added Copy Print-Out as Text and Copy Print-Out as Image.

2019-05-29: release 2.2.1d (source code only)

* Migrated the Android project from Eclipse with ADT to Android Studio.
  Also building the native code for x86 and x86_64 now. Not sure if I should
  release that, but it is convenient for testing in the Android Emulator, now
  that Google no longer releases ARM system images for the emulator.
  The minimum Android API level requirement went from 8 to 14 (2.2 to 4.0), but
  that seems like an acceptable price to pay.

2019-05-24: release 2.2.1c (iOS only)

* Fixed crash in Paste when clipboard contained no text.

2019-05-20: release 2.2.1b (Android only)

* Made the app explicitly single-instance (by adding
  launchMode="singleInstance" to Free42Activity in the app manifest).
  This should eliminate the remaining null-pointer crashes in the native code,
  and also prevent State File Corrupt scenarios.

2019-05-19: release 2.2.1a (Android only)

* Added 64-bit native code.

2019-05-11: release 2.2.1

* Added side margins to print-out window.
* PRLCD is now supported in "Print to Text," using Unicode 2x2 block elements.
* Flag 64 is now set or cleared to indicate the Shift state during the most
  recent key press. This can be used by MENU handlers to implement different
  behaviors for unshifted and shifted menu keys.
* Windows version: Changed sounds from using the Beep() function to playing
  wav sounds using the PlaySound() function, matching the way sounds are played
  in the Android, iOS, and MacOS versions.
* MacOS Dashboard version: Didn't recognize comma as decimal key. Fixed.

2019-04-07: release 2.2

* Implemented YMD mode for date functions, using YYYY.MMDD as the numeric
  format and YYYY-MM-DD as the display format. Programs can check whether this
  mode is active by testing flag 67. If flag 67 is clear, the mode is indicated
  by flag 31 (clear = MDY, set = DMY), as before.
* Local variables. You create them with the new LSTO function, and they
  disappear automatically when the current subroutine ends, by executing RTN or
  END. If a local variable is created with a name that matches an already-
  existing variable, the older variable is hidden until the local variable goes
  away.
* Dynamically growing RTN stack. It is not unlimited; in order to prevent
  infinite recursion from eating up all memory, it maxes out at 1024 levels.
  The new stack behaves a bit different than the old version (and the real
  HP-42S): when an XEQ happens while the stack is full, the old version would
  silently discard the oldest RTN, while with the new version, this returns a
  "RTN Stack Full" error.
* Added support for direct command mapping in skins. This is specified by
  creating Macro: lines where the macro is not a sequence of keystrokes, but a
  command name enclosed in double quotes, e.g., Macro: 40 "SSTãæ
* Windows, MacOS, and Linux versions: In skin layout files, they now look for
  keymap entries tagged as "WinKey:", "MacKey:", or "GtkKey:", respectively.
  This allows embedding keymaps for multiple platforms in one layout file.
  This does mean that old-style keymap entries, with no identifying tags, are
  no longer recognized. Out of all the skins in my collection, the only
  affected skins are desktop/42ck and desktop/42ct. If you use these skins,
  you'll want to download the updated layout files.

2019-03-27: release 2.1.1 (Android only)

* The "Maintain skin aspect ratio" setting didn't stick when the app was exited
  and restarted. Fixed.

2019-03-26: release 2.1

* New functions: SSTãæ(Step Out) and SSTãæ(Step Over). Step Out runs the
  program until the end of the current subroutine; Step Over executes one step,
  but if that step is an XEQ, SOLVE, or INTEG, it runs until the subroutine
  returns, or SOLVE or INTEG are done. When Step Out is performed in a function
  called by SOLVE or INTEG, the program runs until SOLVE or INTEG are done.
* Added SSTãæ(Step Into), which is just an alias for SST. This allows creating
  a row in the CUSTOM menu with SSTãæ SSTãæ and SSTãæ like in typical high-
  level language debuggers.
* Android and iOS versions: Improved "Maintain skin aspect ratio" option: it
  now chooses the largest scale where the skin still fits on the screen in its
  entirety, and centers the skin within the available space.
* iOS version: The "Maintain skin aspect ratio" and "Print to text" options in
  the Preferences were switched. Fixed.
* iOS version: Fixed handling of announcements in the status bar (audio
  recording, active call, active GPS).
* iOS version: Turned optimization back on. It looks like the optimizer bug
  (see release notes for 2.0.21a) has been fixed.

2019-03-18: release 2.0.24h (Android only)

* The screen update logic in the previous version was incorrect and caused the
  app to appear unresponsive on many devices. Fixed.

2019-03-17: release 2.0.24g (Android, iOS, and MacOS)

* Android, iOS, and MacOS versions: Enabled non-integral display scaling.
* Android and iOS versions: Added setting in Preferences to choose whether to
  stretch skins to fill the screen, or to stretch them only to fill the
  available width, while maintaining their original aspect ratio.
* iOS version: Implemented support for landscape orientation.
* iOS version: Fixed alignment of "Done" buttons.

2019-03-08: release 2.0.24f (iOS only)

* Added Haptic Feedback setting in Preferences.

2019-03-03: release 2.0.24e (Android only)

* Fixed crash when calling ON or OFF from a program.
* Fixed a bug that could leave a corrupted state file under certain
  circumstances.

2019-02-28: release 2.0.24d (Android only)

* Fixed crashes while printing.

2019-02-26: release 2.0.24c (Android and iOS)

* Android version: Removed all restrictions on file selection dialogs, and
  instead added a "Home" button, so you can always navigate back to
  /sdcard/Android/data/com.thomasokken.free42 if you get stuck somewhere.
* iOS version: Fixed the white bar that was showing up above the skin on iPads
  running iOS 12.

2019-02-25: release 2.0.24b (Android only)

* Made file selection dialogs full-screen.
* Fixed file selection behavior for Import Programs and Select Skin. It now
  starts in the writable storage directory, but does allow navigation out of
  it.

2019-02-25: release 2.0.24a (Android and MacOS)

* Android version: Lifted file selector directory restriction for Import
  Programs and skin selection, keeping it in place for Export Programs and
  selecting print-out files.
* MacOS version: The previous release broke Import Programs. Fixed.

2019-02-24: release 2.0.24

* Made program pasting a bit more lenient: tabs are now treated as spaces, and
  the following command names are now recognized: x, RCL*, RCLx, RCL/, STOx,
  X#0?, X#Y?, X<>0?, and X<>Y? (in addition to all the alternate spellings that
  were recognized previously).
* iOS version: Added Key Clicks setting in Preferences.
* Windows and MacOS versions: Now refuse to export zero programs. (The other
  versions already did this.) Also tweaked the file selection dialogs a bit.
* Android version: When running on 4.4 (KitKat) or later, now creates the
  storage directory, /sdcard/Android/data/com.thomasokken.free42, as soon as it
  has access. The file selection dialogs are now restricted to this directory
  and its subdirectories.

2019-02-18: release 2.0.23c (iOS only)

* The previous release calculated the skin scale incorrectly for certain skins,
  causing them to be displayed too small. Fixed.

2019-02-17: release 2.0.23b (iOS only)

* Enabled non-integral scaling for skins, so skins can fill the width of the
  screen on iPhone X series (X, XR, XS, XS Max) even if they were designed for
  older models with 3:4 or 9:16 screen aspect ratios.

2019-02-11: release 2.0.23a (iOS only)

* Replaced iPhone X skin with a more screen-filling one.

2019-02-09: release 2.0.23

* SOLVE now tries harder when secant extrapolation gets stuck due to the secant
  being excessively steep.
* 0^0 now returns Invalid Data, not 1, for all combinations of real and complex
  arguments. The rationale for returning 1 was mathematically questionable, and
  Invalid Data is what the real HP-42S returns.
* iOS version: Added basic iPhone X support.

2019-01-26: release 2.0.22c (Android only)

* New Main Menu. This should be compatible with all Android versions, including
  Amazon Fire HD tablets and other devices that sabotaged the old menu after it
  started targeting Android 8.
* Added code to request storage and GPS access when needed.

2019-01-13: release 2.0.22b (Android only)

* Another fix for invisible overflow menu items.

2019-01-12: release 2.0.22a (Android only)

* Fixed invisible overflow menu items.

2019-01-12: release 2.0.22

* Made pasting real scalars a bit more lenient: it is now permitted for there
  to be trailing non-numeric characters after the number, so pasting a number
  with an attached unit, say 50mm, yields the number 50, not the string "50mm".
* INPUT should clear any message from the display before showing the prompt,
  but it didn't. Fixed.
* When ALPHA mode is active on top of VARMENU, ASTO and ARCL should show the
  regular variable menus, but they showed the VARMENU instead. Fixed.
* During command entry, SST and BST should be disabled, but the code that tried
  to do this also prevented some legitimate uses of ãöand  such as switching
  menu rows during FIX IND __.
* While entering a numeric LBL, it should be possible to switch to ALPHA mode,
  using Shift-ENTER, to switch from, say, LBL 3_ to LBL "3_ , as an alternative
  method of entering ALPHA labels that start with a digit. The HP-42S allows
  this, but Free42 didn't. Fixed.
* Android and iOS versions: OFF now turns off "continuous on" mode.

2018-11-24: release 2.0.21b (Windows only)

* Fixed Alt-Tab behavior.

2018-07-03: release 2.0.21a (iOS only)

* Turned off all optimization for release builds; the latest iOS developer
  tools appear to have a buggy optimizer, and it is causing number display in
  OCT and HEX modes to misbehave -- they show numbers with unwanted leading
  zeroes, for a total number of digits that would be appropriate for BIN mode,
  so 1=>1, 2=>02, 3=>03, 4=>004, etc.

2018-06-24: release 2.0.21

* Fixed complex SQRT so it returns exact results when Re(x) = 0 and Im(x)/2 is
  a perfect square.
* VARMENU would step through rows of multi-line menus in the wrong order.
  (You needed a function with 13 or more MVARs to notice this.) Fixed.
* When printing to GIF, changing the filename did not cause the GIF numbering
  sequence to restart at 1. Fixed.
* When printing to GIF, the output file is now flushed and closed immediately
  if there is no more room for at least another 9 pixels after printing -- in
  other words, when no more printing to that file is possible anyway. It used
  to wait until the next print request, or app close, before flushing and
  closing in this situation.
  Also, the minimum height of a GIF output file is now 16 pixels, down from 32.

2018-03-12: release 2.0.20

* MATA, MATB, and MATX should exhibit the same stack lift behavior as EDIT and
  EDITN, but didn't. Fixed.

2018-03-10: release 2.0.19

* Another EDIT/EDITN fix: in the real HP-42S, EDIT and EDITN don't actually
  disable stack lift; they preserve the stack lift state, which you can observe
  if you do ENTER vs. a stack-lift-enabling operation (say, X<>Y) just before
  invoking them. This behavior is not really useful, but it needs to be
  emulated anyway, since not doing so risks breaking HP-42S programs.
  This does not affect GOTO Row/Column.

2018-03-09: release 2.0.18

* EDIT, EDITN, and GOTO Row/Column should disable stack lift, but they didn't.
  Fixed.

2018-03-02: release 2.0.17

* Inserting or deleting an END would not always clear cached local GTO or XEQ
  targets, potentially causing local GTO or XEQ commands to jump to the wrong
  locations. Fixed, and also added code to repair such damage in existing state
  files.

2018-02-22: release 2.0.16

* 0 SEED initialized the random seed incorrectly, wasting one digit of
  randomness. Fixed.
* When importing raw files, E and -E are now recognized as 1 and -1, for
  compatibility with HP-41 raw files with synthetic numbers.
* When importing raw files, synthetic instructions are now handled more like
  the real HP-42S handles them. Basically, any argument >= 100 that isn't a
  stack register and that isn't a local label is treated as numeric. Arguments
  112-116 are always stack registers, even when that makes no sense (flags,
  ΣREG, etc.); 102-111 and 123-127 are only considered as A-J and a-e in LBL,
  GTO, and XEQ.
  Note that nothing very interesting happens as a result of these changes. They
  won't make synthetic HP-41C code work in Free42 any more than it does in the
  HP-42S; the behavior is just more like the real 42S now.

2018-02-17: release 2.0.15

* POSA would not find the search string if its only occurrence was at the very
  end of the alpha register. Fixed.
* Android version: Tweaked handling of low-battery indicator.

2018-02-10: release 2.0.14

* In Export Programs, removed the hard-coded buffer size for the list of
  programs, so you should now see all your programs in the list, no matter how
  many there are.
* When Pasting complex numbers in a+bi notation, the imaginary unit must now be
  either i or j; the alternative spellings I and J are no longer recognized.

2018-02-06: release 2.0.13

* Paste didn't handle numbers with negative exponents correctly. Fixed.

2018-02-02: release 2.0.12d (iOS only)

* Fixed crash in GIF printing.

2018-01-30: release 2.0.12c (Android only)

* Another fix for crash on orientation change while printing.

2018-01-29: release 2.0.12b (Android only)

* Switching between portrait and landscape modes, while printing was in
  progress, could cause a crash. Fixed.

2018-01-28: release 2.0.12a (Android only)

* Fixed handling of state files that were corrupted in a way that caused
  persistent crashes on the first keystroke.

2018-01-27: release 2.0.12

* Fixed pasting of SIZE lines.
* When pasting numbers, spaces are now allowed as thousands separators.
* MacOS and MacOS Dashboard versions: Are now 64-bit.
* MacOS and Linux versions: Fixed Caps Lock handling, so Caps Lock + Esc no
  longer exits.
* Android and iOS versions: Implemented "continuous on" mode (ON function,
  flag 44).

2018-01-26: release 2.0.11a (Android only)

* Removed the cleanup of variables in core_quit(); it looks like this was
  responsible for the failure mode where the app would crash at the first
  keystroke, consistently, forcing uninstall/reinstall.
* Pasting numbers that ended in CRLF, as when copying a single cell from Excel,
  didn't work; they were interpreted as strings. Fixed.

2018-01-14: release 2.0.11

* Copy now ignores flag 29 (thousands separators) and always copies numbers
  without separators. This fixes certain surprising / undesirable behaviors
  when pasting numbers into spreadsheets or programs.
* When entering a program line in NORM or TRACE modes, the line would be
  printed, even when printing was disabled. Fixed.
* MATA and MATB, in the SIMQ menu, would crash if the MATA or MATB variables
  were missing. Fixed, and also cleaned up type checks in MATX.
* Android version: Printing lots of output quickly, for example, by running a
  program in TRACE mode, would cause the user interface to become sluggish or
  even unresponsive on some devices. Fixed by posting UI updates less
  aggressively.

2018-01-07: release 2.0.10

* Program Paste without line numbers didn't handle certain numbers,
  specifically, those that started with a digit and didn't consist of only
  digits. Fixed.

2018-01-07: release 2.0.9

* Program Paste no longer requires line numbers.
* The CUSTOM command would toggle the CUSTOM menu, but that was wrong: it
  should only activate that menu, never deactivate it. Fixed.
* DIM?, EDIT, and EDITN didn't print X in TRACE mode. Fixed.
* Selecting the already-active menu did not cause the display to be repainted,
  even though it should: there might be a message, which should be removed in
  that case. Fixed.
* All versions except MacOS Dashboard: made the print annunciator linger for
  one second after printing stops. This makes it more noticeable, so printing
  is less likely to go unnoticed on fast devices.
* MacOS version: Implemented battery checker.
* Linux version: Added /sys/class/power_supply support in battery checker.

2017-12-26: release 2.0.8

* MENU (activating the programmable menu) while in ALPHA mode didn't turn off
  the alpha_mode flag, leading to bad behavior or even crashes if any menu keys
  were subsequently pressed.

2017-12-21: release 2.0.7c (Windows only)

* Decimal: SIN and COS of 45 degrees or 50 grads returned an inaccurate result,
  correct to only 16 digits. Fixed.

2017-12-18: release 2.0.7b (Android only)

* The "Always Paint Entire Display" setting, introduced in the previous
  version, didn't stick after app restart. Fixed.

2017-12-17: release 2.0.7a (Android only)

* Added "Always Paint Entire Display" option. This prevents display glitches
  with certain combinations of devices and skins.

2017-11-19: release 2.0.7

* Changed the RAN and SEED functions to match the behavior of the real HP-42S.
  The previous implementation used the algorithm from the HP-41C Standard Pac,
  which produced numbers with only 6 significant digits.
* The ¼âÌ´ annunciator (multi-row menu) did not get updated correctly when
  VARMENU was activated, including in the solver and integrator. Fixed.
* Windows version: Restored the Calculator key mapping option, which I had
  removed in 1.5.14. It turns out that keyboards with a dedicated Calculator
  key do still exist.
* Android version: The menu icons for Copy, Paste, and Print-Out were displayed
  too large, overlapping the menu item labels on some devices. Fixed.
* Windows, Linux, MacOS, and MacOS Dashboard versions: Added keyboard mappings
  g => GTO and p => PI. On existing installations, users must delete or rename
  the existing keymap and restart for this to take effect.
* iOS version: Painting the display could be glitchy if either or both of
  its coordinates were odd. Fixed by forcing them to be even.

2017-08-12: release 2.0.6

* Decimal version: Fixed ISG and DSE for values >= 2^63 (9.2e18).
* Fixed a couple of bugs in how changes to internal SOLVE and INTEG data
  structures are handled.

2017-07-30: release 2.0.5

* Fixed INTEG termination condition. It would return inaccurate results in
  certain cases.
* Fixed importing numbers with exponent but no mantissa, e.g. E3, -E-5, etc.
  This got broken in 1.5.
* Fixed crash when trying to allocate ridiculously large matrices.
* While entering a numeric argument, the ãöand keys would perform BST and
  SST, which should be blocked. Fixed.
* Testing flag 75 would turn on the programmable menu. Fixed.
* iOS version: Fixed a few display alignment issues with the built-in 4"
  skin.

2017-05-29: release 2.0.4

* Implemented special-case code for pure real and pure imaginary numbers in all
  the complex logarithmic, trigonometric, and hyperbolic functions.

2017-05-28: release 2.0.3

* Fixed a few edge cases in complex functions.
* The last digit in full-precision representation (SHOW, Copy) could be off by
  one in certain circumstances. Fixed.
* On cold start, now clearing flags 21 (printer enable) and 55 (printer
  existence), to match the behavior of the real HP-42S.
* Removed "raw text" print option; it has been obsolete since the introduction
  of UTF-8 printing in 1.5.11, since Unicode can represent the HP-42S character
  set directly.
* iOS version: LOCAT didn't work when its initial invocation happened from a
  program. Fixed.
* In the About box, replaced the link to the Free42 discussion group with a
  link to the Alternative HP-42S/Free42 Manual.

2017-04-28: release 2.0.2

* In Unicode-to-HP conversion, translate "\LF" and "[LF]" to 10, not 138.
  Character 138 only exists to *represent* LF, but isn't available in the ALPHA
  menu and therefore cannot appear in non-synthetic programs.
* Unicode-to-HP conversion handles curly quotes now (U+2018, U+2019, U+201C,
  U+201D).

2017-04-23: release 2.0.1 (beta)

* Change right-pointing triangle from Unicode U+25B6 (black right-pointing
  triangle) to U+25B8 (black right-pointing small triangle); the former gets
  rendered as an emoji in iOS, while the latter doesn't, plus, the smaller
  triangle looks better in listings anyway.
* MacOS Dashboard version: Fixed multi-line pasting.

2017-04-22: release 2.0 (beta)

* Copy & Paste now handle matrices, ALPHA mode, and PRGM mode.

2017-04-01: release 1.5.15

* Instead of being limited to 12 mantissa digits, full precision (34 digits in
  the Decimal version, 16 digits in Binary) is now supported for number entry,
  SHOW, Copy, and Paste.

2017-03-11: release 1.5.14

* Changed complex TAN and TANH to use more accurate formulae.
* The Time Module functions used to keep track of MDY/DMY modes using an
  invisible flag. For better HP-41 compatibility, they now use flag 31.
* Android version: Made state file writing more robust. If writing the state
  file fails, it now keeps the previous one, instead of leaving behind a
  partial or corrupt one.
* Linux version, Free42 Binary only: Some (recent?) versions of GTK set the
  LC_NUMERIC locale, which Free42 expects to always be "C". This causes number
  entry and display to be messed up in locales where the decimal is not ".",
  including most of Europe. I added code to force LC_NUMERIC back to "C" after
  gtk_init(), fixing this problem.
* Binary version: Fixed binary round-off problem in ADATE (for example,
  10.102010 would be rendered as 10/10/2009).

2017-01-22: release 1.5.13

* When DIM, SIZE, or SIMQ resize the indexed matrix, and when CLV deletes the
  indexed matrix, IJ should be set to (1, 1); and when DIM, SIZE, or SIMQ try
  to resize the matrix currently being edited by EDITN, and when CLV tries to
  delete the matrix currently being edited by EDITN, they should return a
  "Restricted Operation" error. Neither happened, creating the potential for
  memory corruption if IJ ended up pointing outside the matrix' data array.
  Fixed.
* STO and STO* allowed the target to be the matrix under edit by EDITN. They
  should not allow this, but return "Restricted Operation" instead. Fixed.
* CLALL didn't always exit all menus. Fixed.

2016-10-03: release 1.5.12

* Android version: Fixed UTF-8 printing, which was broken in 1.5.11.
* All versions: When printing to text, up-arrow now looks like an up-arrow,
  instead of a caret.

2016-10-01: release 1.5.11

* EXITALL didn't always exit all menus. Fixed.
* Print-to-text now emits UTF-8 encoded text, instead of ISO-8859-1.
* Print-to-text now emits CRLF line separators on all platforms.
* Android version: Didn't save the "raw text" print setting. Fixed.
* Android version: Added landscape skin; made it the default for landscape mode
  in new installs.

2016-09-04: release 1.5.10 (Android, Windows, MacOS, and Linux)

* Fixed AGRAPH bug with complex number in X.

2016-09-04: release 1.5.9 (Android, Windows, MacOS, and Linux)

* Now building the Intel Decimal Floating-Point Math Library from source for
  all targets. In terms of the end user, this makes no difference, but it will
  make life easier for people who want to port Free42 to platforms that I don't
  support myself (FreeBSD, Solaris, etc.); those platforms were left out in the
  cold when I started using the Intel library and only provided pre-built
  binaries for the supported platforms.
* Implemented range reduction for more accurate TAN in DEG and GRAD modes.
* Android version: Now handles orientation change more efficiently.

2016-04-26: release 1.5.8f (Android only)

* Rolled back 8e, which was a disaster; it didn't fix the remaining black
  line issues, but it did cause crashes everywhere.

2016-04-26: release 1.5.8e (Android only)

* The previous fix for the thin-black-line problem didn't do the job on some
  devices. Here's another fix that should do a better job.

2016-04-25: release 1.5.8d (Android only)

* Fixed the thin black lines that would sometimes appear around the display.
* In full-screen mode, swiping down from the top would post the menu, because
  the initial touch would be in the same area that Free42 watches as the menu
  trigger. I changed the code so that the trigger only fires if the user lifts
  their finger while still inside that critical area, which will only happen
  if the downward swipe is very short.
* Fixed the top-of-screen menu trigger so that it no longer sabotages keys
  that are also in that area, as in the HP_Mega_42 skin.

2016-04-24: release 1.5.8c (Android only)

* Implemented true full-screen mode. This hides the navigation bar as well the
  status bar, on devices running Android 4.4 (KitKat) or later.

2016-04-23: release 1.5.8b (Android only)

* Print-Out is now scaled to make better use of available screen width.
* Fixed key clicks.
* Implemented Reverse Portrait (upside-down) mode.

2016-04-17: release 1.5.8a (Android only)

* Tapping in the top half of the display now brings up the app's option menu.

2016-04-17: release 1.5.8

* Entering an END into a program using the CUSTOM menu would leave the program
  counter at an invalid value, leading to memory corruption, state file
  corruption, and crashes. Fixed.
* Android version: Changed haptic feedback code back to using the old API.
* Android version: Changed targetSdkVersion from 3.0 to 2.2. This should make
  the menu reliably accessible in all Android versions and with all display
  styles.
* Resurrected the MacOS Dashboard version; the display repaint logic now
  supports Yosemite (10.10) and later.

2016-03-19: release 1.5.7a (Android only)

* Made the action/title bar optional.
* Added full-screen mode (removes action/title bar and status bar).
* Added installLocation=auto to the manifest, so the app can now be installed
  on an SD card.

2016-02-28: release 1.5.7

* INSR should disable stack lift, but didn't. Fixed.
* Android version: Added Action Bar, reluctantly embracing the reality of
  devices with no menu button (or hard-to-find menu buttons, like the "press
  and hold the task switch button" behavior on some devices).

2014-12-21: release 1.5.6

* iOS version: Implemented Copy and Paste.
* iOS version: Fixed LOCAT for iOS 8.
* All versions, on hard reset, now initializing flag 28 (decimal point/comma)
  to match the host's locale.
* Paste didn't clear the message flags. Fixed.

2014-11-12: release 1.5.5

* Decimal version: Entering a number with an empty exponent (e.g. 1E or 1E-)
  would yield <Not a Number>. Fixed.
* iOS version: HTTP server: Fixed downloading individual programs from, and
  uploading zip files of programs to, the /memory directory. This got broken in
  release 1.4.77, while implementing local file download.
* Android version: When the screen orientation was set to "automatic", it would
  not honor any system-wide orientation lock. Fixed.

2014-11-08: release 1.5.4a (Android only)

* Fixed crash on startup in Android 5.0 (Lollipop).
* Printing to text would truncate the file whenever it was reopened, opening it
  for writing rather than appending. Fixed.

2014-09-23: (no new code release)

* Added nova1_1096 skin, for iPhone 5, to the Free42iPhoneSkins package.
  Contributed by Keith Carangelo.

2014-09-06: release 1.5.4a (iOS only)

* Fixed keyboard handling in the Preferences and Select File dialogs.
* Fixed scrolling behavior (in 1.5.4, windows were sized 20 pixels beyond the
  bottom of the screen, making the bottommost bit of scroll views drop off the
  screen).
* Added 4" skin for iPhone 5, and added code to select the best-fitting built-
  in skin on first launch.

2014-07-22: release 1.5.4

* Decimal version: Fixed ACOS. It would return 0 for acos(-1).
  This bug was introduced in release 1.5.

2014-06-21: release 1.5.3a (Android only)

* Made GPS optional. When I added the ACCESS_FINE_LOCATION permission in
  1.4.78, that had the side effect of making GPS a requirement. In 1.5.3a,
  the app manifest explicitly states that the GPS is not required.

2014-05-25: release 1.5.3

* Fixed crash in SIMQ if any of MATA, MATB, or MATX already existed and was a
  scalar or string.

2014-05-10: release 1.4.78 (Android only)

* Fixed the LOCAT function, by adding the ACCESS_FINE_LOCATION permission.

2014-03-16: release 1.5.2

* Decimal version: Fixed Y^X for complex Y and negative integral X.
* Decimal version: Made Y^X and 10^X for real Y and integral X more accurate.
* All versions: sin(45°) now equals cos(45°), and sin(50grad) = cos(50grad).

2014-03-15: release 1.5.1

* All versions: Fixed ASIN, ACOS, and ATAN so they return exact results in DEG
  and GRAD modes for trivial parameters (asin(1), asin(-1), acos(0), atan(1),
  atan(-1), atan(infinity).
* Now displaying signed zero as zero, so you won't see -0 any more.
* Windows version: Removed the "Free42 Directory" setting from the Preferences.
  The application now looks for a file or directory named "portable" in the
  directory where Free42Decimal.exe or Free42Binary.exe itself is located; if
  it exists, the state.bin, print.bin, and keymap.txt files will be stored in
  this directory as well, and skins will only be loaded from this directory. If
  there is no "portable" item in the executable's directory, it will store
  state.bin, print.bin, and keymap.txt in %APPDATA%\Free42, and it will load
  skins from that directory, and from the executable's directory.

2014-03-09: release 1.5

* Decimal version: Switched from BCD20 to Intel's Decimal Floating-Point
  Library v2.1.
* Binary version: Replaced the old binary-to-decimal and decimal-to-binary
  conversions with code that uses the standard C library's equivalent
  functionality. This fixes final-digit errors in the Binary version, and also
  final-digit errors when switching from the Decimal to the Binary version.
* All versions: Added angle reduction code to make SIN, COS, and ->REC more
  accurate in DEG and GRAD modes.
* Windows version: Now uses %APPDATA%\Free42 as the default Free42 directory
  (for storing state.bin, print.bin, and keymap.txt). This avoids permissions
  problems when people install the executable in a directory to which they
  don't have write access (like the popular choice C:\Program Files).
