igor is preparing a surpprize

I read on 7-Zip forums that this should be the last beta before a new stable release, that it is a very good new, even if the quality of beta releases IMHO were great.

Hello everyone,

the quality of beta releases IMHO were great

Consens! Iirc only one serious bug (regarding creation of zip-files) in last few months. Not too bad for a "one-man-show" (Microsoft -> do you listen?). Great stuff, indeed!

Best regards!

after testing v4.56 i can say the CHM bugs now is solved.. as the techniques mentioned @
http://www.encode.su/forums/index.php?action=vthre ad&forum=1&topic=546&page=0

as a CHM optimizer would produce CHM file with LZX-15 or LZX-18 and either were supported by 7-zip while it run easily on windows.. now it is solved..

I'm testing it, 4.57 seems very good.
It's nice having a new non-beta version, even if latest beta releases quality was great.
BTW, I'll update 7z frontend in upcoming version of PeaZip for it.

Thanks Giorgio!
