|
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. |

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

|
|
13 | - the fix from 3.3 introduced a compression bug, which is fixed in |
|
|
14 | this release (which explains the mysterious prerelease...). Thanks |
|

|
23 | - include a workaround for failing POSIX and real-world compliance |
|
|
24 | on 64 bit windows (microsoft claims to support POSIX, but is far |
|
|
25 | from it). (bug found and analysed nicely by John Lilley). |

28 | - IMPORTANT BUGFIX: a too long final literal run would corrupt data |
|
|
29 | in the encoder (this was introduced in 3.0 only, earlier versions |
|
|
30 | are safe). |
