In a new post to his blog Ruslan Yakushev points out a new build of WinCache (the Windows caching tool for PHP) that makes life easier for WordPress users who want it to be able to to the auto-upgrade correctly.

The WinCache extension 1.1 for PHP has been released last year. Since then several customers reported a bug in the extension that prevents WordPress and other PHP applications from performing automatic upgrades or their plugins. This was reported on WordPress forum as well as on WinCache forum. The new build of WinCache with the fix for this problem is available now at the following location: https://sourceforge.net/projects/wincache/files/development/

He asks for feedback if things still don't work - either as a comment in the WinCache forum or as a bug to the PECL database. This will help them improve the support in future releases and make it even easier for those running WordPress on Windows to keep their sites running smoothly.
