• Release Date: Apr 24, 2006
• AviSynthDocs+257.zip and AviSynthSrc+257.zip are incremental source updates based on the last itme the public CVS server was synchronised, 30th Mar 2006.

• Release Date: Apr 6, 2006
• This installer does not abort on registry error, to aid in debugging the current XPsp2 problem with the installer. i.e. it just stumbles on after the mesagebox, possibly leaving an invalid install. This will be restored after the problem is corrected.
• This version has had the automatic output ConvertAudioTo16Bit disabled to ease the testing of input of WAVE_FORMAT_IEEE_FLOAT type steams. Audio Sample type float will be output as WAVE_FORMAT_IEEE_FLOAT to the host application. None of the popular application can currently handle this stream type. Add a ConvertAudioTo16Bit() to the end of your script. This will be restored for the next release.
