Batcache 1.2

10 Dec

Batcache version 1.2 was released today. It fixes a fun bug that could cause incorrect cached content to be returned in some cases. The default Batcache key has been updated to include $_SERVER['REQUEST_METHOD'] which means when you upgrade, all of your keys will be immediately invalidated. For most folks using a short TTL this won’t matter. It’s a good idea to upgrade. Download version 1.2 today!
