Recent changes: ^^^^^^^^^^^^^^^ +20070422: + The way OS emulations lookup filenames inside the emulation root + has been changed. Rather than modify the pathname (and copy back + to userspace) namei() and lookup() directly check the emulation + root. One side effect is that absolute symlinks inside the emulated + root filesytem will be relative to that filesystem - unless they + start /../ this is useful when the emulated root is a real install + that has such links. + This might affect symlinks that have been added to reference outside + the emulated root. + +20070412: + The pckbc driver on sgimips IP32 has been removed. Use macekbc + instead. See the GENERIC32_IP3x kernel configuration for an + example. + +20070319: + src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so + on many platforms due to incorrect flags settings. If you + updated and built after about 20070315, do "nbmake-$arch + cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a + rebuild of object files that might have been built + incorrectly, and ensure that you have at least + src/lib/libc/Makefile 1.130. + +20070210: + src/sys/sys/{sa.h,savar.h} were removed. + find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ + | xargs egrep -l '/sa.h|/savar.h' | xargs rm + will allow dependencies on those files to get get rebuilt + +20070209: + The threading model was changed when the newlock2 branch + was merged to NetBSD-current. 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.

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.
