When will he increase the "the planned release of a public version has been delayed until sometime 2010. " to 2011 like he use to? >

... LZO Professional is currently undergoing final pre-release cycles and is scheduled for early 2011.

Here are some news from lzo:

http://www.oberhumer.com/products/lz...onal/showcase/

but there is only a compare with zlib 1.2.5 and lzo 2.04

it will be interesting to see a compare with
- qpress 1.1 from http://www.quicklz.com/
- bsc 2.4.0 from http://libbsc.com/
- 7zip 9.20 (with fast ppmd) from http://www.7-zip.org/
- rings 1.5c form http://heartofcomp.altervista.org/

the best feature IMHO is the complete compatibility with lzo 1.x !

best regards

>it will be interesting to see a compare with
also with tornado/thor/slug and nania's fast lz. and rar -m1

23 Apr 2011 - LZO 2.05 has been released

http://www.oberhumer.com/opensource/lzo/

Changes in 2.05 (23 Apr 2011)
* Converted the configure system to non-recursive Automake
* Applied some overdue "speed optimizations" for
modern x86/x64 architectures
and current compilers like gcc 4.6 and MSVC 2010

"speed optimizations" ..

it seems interesting to compare it with "snappy 1.0"

anyone has it successfully compiled for win32 or win64 ?

Anyone compile this for win32? Would love to test a binary.
