+ * Eliminate the use of AutoGen. This allowed some performance
+ improvements to the build system.
+ * Remove variable length arrays.
+ * OpenBSD compile and tools support (NetBSD and FreeBSD were already supported).
+ * Fix build with FreeType >= 2.5.1.
+ * Make gentpl.py compatible with Python 3. It now requires at least
+ Python 2.6.
+ * modinfo.sh contains build information now.
+ * Added many new tests to improve robustness.
+ * Target is built without libgcc now. Necessary builtins are reimplemented
+ directly. This removes requirement for target-specific runtime on build
+ system.
+ * emu libusb support removed (was broken and unmaintained).
+ * powerpc64le compile support.
+ * Use fixed timestamp when generating GRUB image for reproducible builds.
+ * Verify at build time that modules contain only supported relocations and their
+ structure matches what boot-time module loader expects.
+ * Do not require fonts on powerpc-ieee1275.
+
+* Revision control moved to git.
