+
+- **Bug Fix**: Fixed a bug in the Quick Cache back compat. method `\zencache\share\apply_wp_filters()`. It was not passing the ZenCache-filtered value through the Quick Cache back compat. routine. This bug affected sites that had disabled automatic cache clearing routines via a filter.
+- **Bug Fix** (Pro): Updated Static CDN Filters whitelist to include font file extensions `eot,ttf,otf,woff`, as site owners may wish to serve fonts with these extensions from the CDN (this would require a custom CORS configuration; see [this article](http://davidwalsh.name/cdn-fonts) for instructions). See [#427](https://github.com/websharks/zencache/issues/427).
+- **Bug Fix** (Pro): Updated Static CDN Filters blacklist to exclude font file extensions `eot,ttf,otf,woff` by default, as they require custom CORS configuration to display properly. See [#427](https://github.com/websharks/zencache/issues/427).
+- **Bug Fix** (Pro): The Static CDN Filters feature was calling a protected method that was requiring PHP v5.4+ but now the Static CDN Filters feature works with PHP v5.3+. See [#426](https://github.com/websharks/zencache/issues/426).
+- **Bug Fix**: Fixed a zero-byte `advanced-cache.php` bug related to migrating from Quick Cache. When you deleted/uninstalled Quick Cache after upgrading to ZenCache, the Quick Cache uninstallation process would empty the `advanced-cache.php` file, resulting in the site no longer being cached, despite ZenCache being active. ZenCache now continuously checks to make sure that `advanced-cache.php` is installed properly. See [#432](https://github.com/websharks/zencache/issues/432).
