+	- switched to 2-clause bsd with "GPL v2 or any later version" option.
+        - speed up compression by ~10-15% in common cases
+          by some manual unrolling.
+        - import some compiler tricks from JSON::XS, for further speed-ups.
+        - tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
+        - for typical binary data (e.g. /bin/bash, memory dumps,
+          canterbury corpus etc.), speed is now comparable to fastlz, but
+          with better compression ratio. with ULTRA_FAST, it's typically
+          3-15% faster than fastlz while still maintaining a similar ratio.
+          (amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
+        - undo inline assembly in compressor, it is no longer helpful.
+        - no changes to the decompressor.
+        - use a HLOG of 16 by default now (formerly 15).
