The IIS team has been working on an updated version of the Windows Cache Extension in order to address the compatibility issues that were discovered after PHP 5.4 was released. With that in mind, we have uploaded the a pre-release development build of the Windows Cache Extension on the SourceForge website at the following URL:
http://sourceforge.net/projects/wincache/files/development/
For anyone that is experiencing issues with the Windows Cache Extension, please download and take a look at the pre-release version that our team has uploaded.
Known Issues
This is an ongoing project, so please bear in mind that this is an early version of this extension, and it still has several issues that our team is actively investigating. The two most significant issues that we are concentrating on are some crashes that we are currently seeing with Sugar CRM and Symfony.
If you run into any problems, please post a description of the problem to the Windows Cache Extension for PHP forum, or you can contact me through the IIS.net web site.
Source Code Availability
Since this is an open source project, the IIS team has uploaded the pre-release source code for the 1.3.0 version at the following URL:
http://pecl.php.net/package/WinCache
For the instructions on how to build the extension yourself, please refer to the Building WinCache Extension documentation.
