If you boot with a new + kernel (version 4.99.10), then you also need a new pthread + library (/usr/lib/libpthread.so.0.7). If you boot with + an old kernel, then you need the old pthread library + (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and + the pthread library in sync, old threaded applications should + continue to work with an old or new kernel. Note that named(8) + is the only threaded application in the base system. + +20061214: + Following the move of string_to_flags() and flags_to_string() + from the bin/ls/ sources to libutil, users doing UPDATE builds + will need to do a "make cleandir" in + tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, + bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, + usr.bin/xinstall/, libexec/ftpd/, rescue/, as well + as the installation images in distrib/ + in order to excise stale references to the old stat_flags.h header + file in the ls sources -- stat_flags.h has been removed. + +20061108: + The configure script used in the src/tools/gcc compiler has been + changed to indicate that our libc has ssp support built-in and + does not depend on -lssp and -lssp-nonshared. You'll need to + make clean in src/tools/gcc first to rebuild the compiler. + +20061009: + The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer + available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. + +20060814: + The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been + withdrawn. Use vidcvideo and pckbd instead. See the GENERIC + kernel configuration for an example. X servers from the last + few years should cope. + +20060703: + MPACPI is no more. We always configure PCI interrupts using ACPI + if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed + to ACPI_SCANPCI. Thanks to work from fvdl. + +20060627: + socket(2) has changed, and its system call has been versioned. + For userlands with the old version of socket(2), make sure that + your kernel has 'options COMPAT_30' set, or else 'bad system call' + errors will result. + +20060526: + The kernel linker scripts for i386 and xen + (sys/arch/i386/conf/kern.ldscript*) were changed to set the + load address correctly, for the benefit of MULTIBOOT boot loaders + (like Grub). If you use a linker (ld) older than from 2006/04/17, it + will be unable to link the kernel because of a bug and ld will fail + with an error like: + ../../../../arch/i386/conf/kern.ldscript:45 \ + non constant expression for load base + You need to update at least src/gnu/dist/binutils/ld and recompile + and install the linker.

When using build.sh, the linker binary is + installed as ${TOOLDIR}/bin/i386--netbsdelf-ld. + +20060131: + the protocol between the sparc64 bootloader (ofwboot) and + the kernel was changed.

After a full build, just copy + /usr/mdec/ofwboot to /, or do a rebuild of + src/sys/arch/sparc/stand/ofwboot and install the result to /. + +20050917: + arch/*/conf/std.* was changed to include conf/std, which + contains MI options previously enabled by default. + If you have kernel config files which doesn't include + arch/*/conf/std.*, you need to edit them to include conf/std + to get the previous configuration. + +20050830: + named.conf was moved from /etc/namedb to /etc. + postinstall(8) migrates this during interactive use. + Users of MKUPDATE=yes will need to manually rectify + this in their DESTDIR. + +20050825: + Some data structures in sys/device.h, related to interface + attributes and locator names, were changed. config(1) was + modified to emit the new data structures. + Thus usr.bin/config must be updated (and run on the kernel + configuration file) before a new kernel can be built. + +20050531: + genassym.sh(8) was moved to genassym(1). You need to either build + tools first or install the version of genassym from /usr/bin before + you can build a kernel again. + +20050520: + Because a kernfs bug which xentools relies on was fixed, + xentools up to xentools20-2.0.3nb4 won't work with new kernel. + +20050417: + postinstall(8) was moved from /etc to /usr/sbin and made part + of the "base" set, to make it easier to invoke after an + upgrade. + +20050325: + pcppi(4) was separated in two devices, adding attimer(4). Be sure + to add a config line for an attimer(4) device in your kernel + configuration, or you won't be able to set the pitch of the beep + with wsconsctl. Depending on the default value for the pitch, you + might even not hear any more beep. Also, it is advised to attach both + devices the same way (i.e., both on isa or both on acpi) or the + pcppi(4) device may fail to find the attimer(4) one. + +20050211: + Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in + some of the cross tools to fail if they use configure.
