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.
