+Snappy v1.1.3, July 6th 2015:
+
+This is the first release to be done from GitHub, which means that
+some minor things like the ChangeLog format has changed (git log
+format instead of svn log).
+
+ * Add support for Uncompress() from a Source to a Sink.
+
+ * Various minor changes to improve MSVC support; in particular,
+ the unit tests now compile and run under MSVC.
+
+
+Snappy v1.1.2, February 28th 2014:
+
+This is a maintenance release with no changes to the actual library
+source code.
+
+ * Stop distributing benchmark data files that have unclear
+ or unsuitable licensing.
+
+ * Add support for padding chunks in the framing format.
+
+
+Snappy v1.1.1, October 15th 2013:
+
+ * Add support for uncompressing to iovecs (scatter I/O).
+ The bulk of this patch was contributed by Mohit Aron.
+
+ * Speed up decompression by ~2%; much more so (~13-20%) on
+ a few benchmarks on given compilers and CPUs.
+
+ * Fix a few issues with MSVC compilation.
+
+ * Support truncated test data in the benchmark.
+
+
+Snappy v1.1.0, January 18th 2013:
+
+ * Snappy now uses 64 kB block size instead of 32 kB. On average,
+ this means it compresses about 3% denser (more so for some
+ inputs), at the same or better speeds.
+
+ * libsnappy no longer depends on iostream.
+
+ * Some small performance improvements in compression on x86
+ (0.5–1%).
+
+ * Various portability fixes for ARM-based platforms, for MSVC,
+ and for GNU/Hurd.
+
+
+Snappy v1.0.5, February 24th 2012:
+
+ * More speed improvements. Exactly how big will depend on
+ the architecture:
+
+ - 3–10% faster decompression for the base case (x86-64).
+
+ - ARMv7 and higher can now use unaligned accesses,
+ and will see about 30% faster decompression and
+ 20–40% faster compression.
+
+ - 32-bit platforms (ARM and 32-bit x86) will see 2–5%
+ faster compression.
+
+ These are all cumulative (e.g., ARM gets all three speedups).
+
+ * Fixed an issue where the unit test would crash on system
+ with less than 256 MB address space available,
+ e.g. some embedded platforms.
+
+ * Added a framing format description, for use over e.g. HTTP,
+ or for a command-line compressor. We do not have any
+ implementations of this at the current point, but there seems
+ to be enough of a general interest in the topic.
+ Also make the format description slightly clearer.
+
+ * Remove some compile-time warnings in -Wall
+ (mostly signed/unsigned comparisons), for easier embedding
+ into projects that use -Wall -Werror.
+
+
+Snappy v1.0.4, September 15th 2011:
+
+ * Speeded up the decompressor somewhat; typically about 2–8%
+ for Core i7, in 64-bit mode (comparable for Opteron).
+ Somewhat more for some tests, almost no gain for others.
+
+ * Make Snappy compile on certain platforms it didn't before
+ (Solaris with SunPro C++, HP-UX, AIX).
+
+ * Correct some minor errors in the format description.
+
+
+Snappy v1.0.3, June 2nd 2011:
+
+ * Speeded up the decompressor somewhat; about 3-6% for Core 2,
+ 6-13% for Core i7, and 5-12% for Opteron (all in 64-bit mode).
+
+ * Added compressed format documentation. This text is new,
+ but an earlier version from Zeev Tarantov was used as reference.
+
+ * Only link snappy_unittest against -lz and other autodetected
+ libraries, not libsnappy.so (which doesn't need any such dependency).
+
+ * Fixed some display issues in the microbenchmarks, one of which would
+ frequently make the test crash on GNU/Hurd.
+
+
+Snappy v1.0.2, April 29th 2011:
+
+ * Relicense to a BSD-type license.
+
+ * Added C bindings, contributed by Martin Gieseking.
+
+ * More Win32 fixes, in particular for MSVC.
+
+ * Replace geo.protodata with a newer version.
+
+ * Fix timing inaccuracies in the unit test when comparing Snappy
+ to other algorithms.
+
+
+Snappy v1.0.1, March 25th 2011:
+
+This is a maintenance release, mostly containing minor fixes.
+There is no new functionality. The most important fixes include:
+
+ * The COPYING file and all licensing headers now correctly state that
+ Snappy is licensed under the Apache 2.0 license.
+
+ * snappy_unittest should now compile natively under Windows,
+ as well as on embedded systems with no mmap().
+
+ * Various autotools nits have been fixed.
+
+
+Snappy v1.0, March 17th 2011:
+
+ * Initial version.
