For more details on the fixsb script, see pr install/25138. + +20040418: + statfs(2) and friends have been replaced with statvfs(2). Before + installing a newly build userland make sure that you are running + a newly built kernel with COMPAT_20 set.

The file is now stored as a uuencoded file in CVS + and the generated Makefile will use the new .uue rules from bsd.file.mk + to build it. + + This means you must have the latest bsd.files.mk installed when + building a kernel without USETOOLS=yes. + +20040318: + A bug in the cgd(4) blowfish code was corrected, without + provision of backwards compatibility, after several public + notices over several months.

If you have been using -current + since 20030402, you may find that fsck again signals fatal + superblock mismatches. To repair, make sure you have + an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4 + to complete the filesystem upgrade.

This should only + affect users who installed or upgraded in September of 2003. + A small utility program was posted to tech-kern which + should fix this problem, and a warning message was added + to the kernel which should discover and warn about it. See + http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html + +20030906: + With the addition of siginfo support the old signal trampoline + code has been deprecated to COMPAT_16.

If you upgrade your kernel, + make sure you also upgrade mountd, because if your export + file contains lines with an old inet4 address syntax (i.e. + a.b.c or a.b or a), they will get rejected by the new kernel. + +20030402: + The superblock layout for FFS was changed. If you have 1.6 + fsck binaries, they will signal a fatal superblock mismatch + with the first alternate, because they compare too many + fields (even ones that aren't useful). If possible, upgrade + your fsck_ffs binary before using a new kernel. + None of this signals actual filesystem damage. + +20030324: + sendmail version 8.12.8 was imported. Since sendmail is + now setgid to the smmsp group, and runs in "collection" + mode for most common activities, there is a new config + file called submit.cf that needs to live in /etc/mail. + The generic submit.cf sample in /usr/share/sendmail/cf + is named netbsd-msp.cf. Upgrading your regular sendmail + configuration file is also strongly advised. + + See the section named "MESSAGE SUBMISSION PROGRAM" in + the updated /usr/share/sendmail/README file for more + information. + +20030117: + Texinfo was updated to 4.3.

The process of rebuilding + libtool will cause it to automatically notice the new + required files, but it *must* be rebuilt in order to + do this. + + An out-of-date libtool will result in shared libraries + which lack _init() and _fini() routines, which means that + their global contructors/destructors will not be invoked. + +20021121: + A bug related to how ARM ELF objects were tagged has been + corrected. + + NetBSD ARM ELF uses the soft-VFP floating point model by + default. However, the assembler lacked support for marking + objects as using the VFP floating point format, and the + compiler was not properly passing the flag indicating "soft-VFP" + to the assembler. + + Unfortunately, this means that the linker will now consider + old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be + incompatible with new (properly marked) objects. + + The problem will only manifest itself if you attempt to compile + a new program using the fixed toolchain, and link that program + against old libraries which do not have the proper "softvfp" + markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES + WILL CONTINUE TO WORK PROPERLY. + + The only work-around for the problem is to recompile all of + the libraries on the system. The easiest way to do this for + system libraries is to install a binary snapshot; they are + generally available on releng.NetBSD.org. Any packages you + have installed which supply libraries will have to be recompiled + if you wish to link new programs against those libraries. + + If you have questions about this matter, please contact + port-arm@NetBSD.org. + +20021011: + Systrace has been improved to support privilege elevation. + Updating the kernel requires the userland part of systrace + to be rebuilt. + +20021010: + The config(8) grammar was changed to allow options to register + dependencies on attributes, as well as other options. Users + must update and reinstall usr.sbin/config before building a new + kernel. + +20021009: + A new attribute dependency syntax was introduced to config(8), + which is now used by the SCSI configuration description.
