1 Snappy v1.0.5, February 24th 2012:
3 * More speed improvements. Exactly how big will depend on
6 - 3–10% faster decompression for the base case (x86-64).
8 - ARMv7 and higher can now use unaligned accesses,
9 and will see about 30% faster decompression and
10 20–40% faster compression.
12 - 32-bit platforms (ARM and 32-bit x86) will see 2–5%
15 These are all cumulative (e.g., ARM gets all three speedups).
17 * Fixed an issue where the unit test would crash on system
18 with less than 256 MB address space available,
19 e.g. some embedded platforms.
21 * Added a framing format description, for use over e.g. HTTP,
22 or for a command-line compressor. We do not have any
23 implementations of this at the current point, but there seems
24 to be enough of a general interest in the topic.
25 Also make the format description slightly clearer.
27 * Remove some compile-time warnings in -Wall
28 (mostly signed/unsigned comparisons), for easier embedding
29 into projects that use -Wall -Werror.
32 Snappy v1.0.4, September 15th 2011:
34 * Speeded up the decompressor somewhat; typically about 2–8%
35 for Core i7, in 64-bit mode (comparable for Opteron).
36 Somewhat more for some tests, almost no gain for others.
38 * Make Snappy compile on certain platforms it didn't before
39 (Solaris with SunPro C++, HP-UX, AIX).
41 * Correct some minor errors in the format description.
44 Snappy v1.0.3, June 2nd 2011:
46 * Speeded up the decompressor somewhat; about 3-6% for Core 2,
47 6-13% for Core i7, and 5-12% for Opteron (all in 64-bit mode).
49 * Added compressed format documentation. This text is new,
50 but an earlier version from Zeev Tarantov was used as reference.
52 * Only link snappy_unittest against -lz and other autodetected
53 libraries, not libsnappy.so (which doesn't need any such dependency).
55 * Fixed some display issues in the microbenchmarks, one of which would
56 frequently make the test crash on GNU/Hurd.
59 Snappy v1.0.2, April 29th 2011:
61 * Relicense to a BSD-type license.
63 * Added C bindings, contributed by Martin Gieseking.
65 * More Win32 fixes, in particular for MSVC.
67 * Replace geo.protodata with a newer version.
69 * Fix timing inaccuracies in the unit test when comparing Snappy
73 Snappy v1.0.1, March 25th 2011:
75 This is a maintenance release, mostly containing minor fixes.
76 There is no new functionality. The most important fixes include:
78 * The COPYING file and all licensing headers now correctly state that
79 Snappy is licensed under the Apache 2.0 license.
81 * snappy_unittest should now compile natively under Windows,
82 as well as on embedded systems with no mmap().
84 * Various autotools nits have been fixed.
