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. |
