1 | |
|
|
2 | - fixed hash calculation in C♯ version (Tiago Freitas Leal). |
|
|
3 | - unroll copy for small sizes, use memcpy for larger sizes, |
|
|
4 | greatly speeding up decompression in most cases. |
|
|
5 | - finally disable rep movsb - it's a big loss on modern intel cpus, |
|
|
6 | and only a small win on amd cpus. |
|
|
7 | - improve c++ compatibility of the code. |
|
|
8 | - slightly improve compressor speed. |
|
|
9 | - halved memory requirements for compressor on 64 bit architectures, |
|
|
10 | which can improve the speed quite a bit on older cpus. |

|
|
13 | - lzf_compress did sometimes write one octet past the given output |
|
|
14 | buffer (analyzed and nice testcase by Salvatore Sanfilippo). |

|
16 | 3.4 Tue Sep 2 06:45:00 CEST 2008 |
|
|
17 | - the fix from 3.3 introduced a compression bug, which is fixed in |
|
|
18 | this release (which explains the mysterious prerelease...). Thanks |
|
|
19 | once more to Clément Calmels. |

21 | 3.3 Mon Aug 25 03:17:42 CEST 2008 |
|
|
22 | - lzf_compress could access memory after the given input buffer |
|
|
23 | when outputting back references. reported with nice testcase |
|
|
24 | by Clément Calmels. |

26 | 3.2 Fri May 9 18:52:23 CEST 2008 |
|
|
27 | - include a workaround for failing POSIX and real-world compliance |
|
|
28 | on 64 bit windows (microsoft claims to support POSIX, but is far |
|
|
29 | from it). (bug found and analysed nicely by John Lilley). |

31 | 3.1 Fri Nov 30 11:33:04 CET 2007 |
|
|
32 | - IMPORTANT BUGFIX: a too long final literal run would corrupt data |
|
|
33 | in the encoder (this was introduced in 3.0 only, earlier versions |
|
|
34 | are safe). |
|
