v150314

• 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 for instructions). See #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.
• 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.
• 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.

v150129

• Bug Fix (Pro): Fixed a bug where the Pro Updater would fail when FTP or SFTP details via the WordPress Dashboard are required to perform updates. Props @jaswsinc. See #389.
• Bug Fix: Several fixes for a stubborn bug related to "Fatal Error: 'Unable to clear dir'" error messages and errors referencing "SplFileInfo::getMTime(): stat failed". Props @jaswsinc. See #397.
• Bug Fix (Pro): Fixed a bug where the qcAC variable (used to force-enable/disable GET Request caching) was not respected properly whenever a URL contained a query string and a user was currently logged into the site. Props @jaswsinc. See #401.

v150121 (Release Candidate)

• Bug Fix (Pro): Fixed a bug where the Pro Updater would fail when FTP or SFTP details via the WordPress Dashboard are required to perform updates. Props @jaswsinc. See #389.

v141231

• Bug Fix: Addressed another issue related to "Fatal Error: 'Unable to clear dir'" and tmp directories that don't get cleared by Quick Cache. This fix discards iteration references before renaming the tmp directories. Props @jaswsinc. See #288.
• Bug Fix: We have had a few reports of getMTime Stat failing when clearing the cache. This fix clears the Stat Cache before iteration when deleting files from the cache directory. Props @jaswsinc. See #385.
• Enhancement: Added a new filter (quick_cache\\share_disable_cache_locking) to allow disabling cache locking. Simply return boolean TRUE to this filter to disable cache locking. This may be useful for site owners who are experiencing issues with cache locking on web hosting platforms with filesystems that don't properly support locking. Note that this filter must be applied using an Advanced Cache Plugin (see Dashboard → Quick Cache → Plugin Options → Theme/Plugin Developers). See also #387.
• Enhancement: Added a new filter that allows forcing Semaphore cache locking on hosting platforms where sem_get() is available and would result in improved performance. Return sem to the quick_cache\\share::cache_lock_lock_type filter to force Semaphore cache locking, or flock to use the default method that uses flock(). Note that this filter must be applied using an Advanced Cache Plugin (see Dashboard → Quick Cache → Plugin Options → Theme/Plugin Developers). See also #387.

v141205

• Bug Fix: Addressed another issue with "Fatal Error: 'Unable to clear dir'" messages by adding new blocking methods for cache lock and unlock, making it so that cache writes (including clearing, purging, wiping) all gain an exclusive lock on the cache directory while work is underway. Props @jaswsinc. See #288.
• Bug Fix: Fixed a Home Page clearing bug that arose in the previous release as the result of an extra leading \/ in one of our regex patterns. Props @jaswsinc. See #365.

Note: This release includes a hotfix for a bug discovered in v141204. See this comment for details.
