+2.2
+	- switched to GPL v2 or any later version.
+        - speed up compression by ~10-15% in common cases
+          by some manual unrolling.
+        - import some compiler tricks from JSON::XS.
+        - 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, it is no longer helpful.
+        - no changes to the decompressor.
+        - use a HLOG of 16 by default now (formerly 15).

+2.1  Fri Nov  2 13:34:42 CET 2007
+	- switched to a 2-clause bsd license with GPL exception.
+	- get rid of memcpy.
+        - tentatively use rep movsb on x86 and x86_64 (gcc only) for a
+          moderate speed improvement.
+        - applied patch by Kein-Hong Man to maske lzf.c compile under
+          the crippled mingw32 environment.

+2.0  Fri Feb 16 23:11:18 CET 2007
 	- replaced lzf demo by industrial-strength lzf utility with behaviour
           similar other compression utilities. Thanks for Stefan Traby for
           rewriting it!
+        - fix state arg prototype.

-	- remove bogus broken horrific "unlzf" patch by Scott Feeney,
+	- remove bogus "unlzf" patch.
           note to self: never accept well-meant patches.
 	- make lzf more robust in presence of padding bytes or sudden eof.
