Based on the user's feedback (which was all positive) we decided to release WINCACHE 1.0.1 today. I would advise everybody using WINCACHE to switch to the new stable version even if you are not seeing any problem with current builds. This version has got a critical fix and is good enough reason to upgrade to the newer bits.
Fixes in this release include problems with require_once, some pathing problems, a few changes to the wincache.php file and a few other smaller changes to help with the overall stability. You can download this latest release from the project's SourceForge page. However, if you want a thread-safe version, you'll need to compile it yourself.
