crosstool-NG

Two new architectures have been added: Blackfin and MIPS64. Building of canadian-crosses has been improved. Experimental support for GCC 4.5.0 has been added. Optimization for size has been added to eglibc (instead of speed by default). The companion libraries can now be built statically, removing the need for the tools wrapper. Many component versions have been added, and associated patchsets updated. Usability and stability has been improved. A lot of bugs have been fixed, some that help building on Darwin on *BSD.

cc is now correctly symlinked to gcc on systems that have file extensions (eg. .exe). The cross-gdb build has been fixed. Forced libraries are corectly handled when populating the rootfs. Extracting MPFR >= 2.4.0 has been fixed. New patches have been added to newlib (to fix m68k alignment), gcc (PowerPC build), and glibc (sjlj for ARM).

All samples have been fixed. A patch has been added for old glibc versions to recognize newer binutils. Building ltrace has been fixed on x86 and powerpc. Auto-completing sample names has been fixed.

Two new architectures have been added: s390 and m68k.
Support for ARM noMMU, THUMB, and interworking has been added.
Newlib has been enabled for all architectures (not limited to AVR32).
Support has been added for the latest gcc-4.4 series, and
many other components' versions have been updated.
The documentation has been (slightly) updated.
A lot of bugs have been fixed.

Installation has been fixed when using --libdir and/or --docdir. The Linux kernel version strings have been fixed. Two uClibc-related bugs (a latent bug in non-ARM builds, and IP frames in big endian) have been fixed. A check that the destination directory is specified has been added. The ncurses download has been fixed and sped up. Sanitizing the environment has been fixed with respect to GREP_OPTIONS.
