| 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. |
