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.
