What's new in AviSynth 2.6.0 Alpha 1:

August 31st, 2009

· The main pupose of this release is to confirm compatibility with version 2.5.8. For scripts using only 2.5.8 features the results should be identical.

· This version does not contain all of the latest features in the experimental 2_6 CVS tree. It supports Y8, YV24 and YV16 colour spaces in most existing filters. Other features will be imported in an on going manner.

· Note this installer does not include any of the documentation. You should install 2.5.8 and then install this version over the top.
