 == Changelog ==
 
+= v150409 =
+
+- **Enhancement (includes improved CloudFlare support)**: Improvements to IP address detection, including added support for CloudFlare IP forwarding, multiple IPs in a single header, and the ability to customize the lookup order and/or add/remove sources that are searched when looking for the current IP address. It's also possible to revert to the old IP address detection behavior (see [How do I customize remote IP detection?](http://zencache.com/kb-article/how-do-i-customize-ip-address-detection/)). Props @jaswsinc. [Issue #449](https://github.com/websharks/zencache/pull/449)
+- **Enhancement** (Pro): Files being served by the HTML Compressor were being sent without a `Vary: Accept-Encoding` header, which caused some page speed testing services to give a lower rating to sites using ZenCache. ZenCache now ensures this header is sent via an `.htaccess` file inside the HTML Compressor cache directory (requires Apache 2.1+). Props @jaswsinc. [Issue #436](https://github.com/websharks/zencache/issues/436).
+- **Enhancement** (Pro): Static CDN Filters now also filter any static resources inside Text Widgets, so that those resources can be cached by your CDN. Props @jaswsinc. [Issue #430](https://github.com/websharks/zencache/issues/430)
+- **Enhancement** (Pro): Static CDN Filters now apply to minified and compressed CSS/JS files generated by the HTML Compressor; these files will now be cached by your CDN. Props @jaswsinc. [Issue #429](https://github.com/websharks/zencache/issues/429)
+- **Bug Fix**: Fixed a bug related to the Quick Cache migration that resulted in caching being disabled despite ZenCache being enabled. Uninstalling Quick Cache was removing `define('WP_CACHE', TRUE);` from the `wp-config.php` file. ZenCache now makes sure that caching remains enabled after uninstalling Quick Cache during the ZenCache migration process. [Issue #450](https://github.com/websharks/zencache/issues/450).
+- **Bug Fix**: Fixed a minor UI issue where the ZenCache Dashboard icon would occasionally flash to a black color when refreshing the Dashboard. Props @jaswsinc. [Issue #453](https://github.com/websharks/zencache/issues/453).
+- **Bug Fix**: When ZenCache was running on an installation of PHP with `open_basedir` restrictions applied, calls to `is_dir()` were triggering a PHP Warning while looking for a writable temporary directory. This bug has been fixed. [Issue #456](https://github.com/websharks/zencache/issues/456).
+- **Bug Fix**: Fixed a bug where changing the permalink for a published post would result in the cache file for the old permalink being left behind and as a result both the old and the new permalink would be accessible, instead of WordPress redirecting the old permalink to the new one. This has been fixed and ZenCache now properly clears the old cache file when changing the permalink on a published post. [Issue #359](https://github.com/websharks/zencache/issues/359).
+- **Bug Fix**: Fixed a bug where transitioning a Published post back to Pending or Draft would not automatically clear the cache file. This resulted in the post remaining accessible on the frontend despite being set as Pending or Draft. ZenCache now properly clears the cache file automatically when transitioning from Published to Pending or Draft, which prevents access to the post as expected. [Issue #441](https://github.com/websharks/zencache/issues/441).
+- **Bug Fix** (Pro): Some users reported seeing `Warning: trim() expects parameter 1 to be string`. This was produced by a low-impact bug that has been fixed in this release. [Issue #455](https://github.com/websharks/zencache/issues/455).
+- **Bug Fix** (Pro): Some users running the HTML Compressor reported seeing 403 Forbidden errors related to loading the compressed/minified files. This was a permissions-related issue that has been resolved in this release. Props @superian and @jaswsinc. See [Issue #50](https://github.com/websharks/html-compressor/issues/50).
+- **Bug Fix** (Pro): Some HTTP requests made by the HTML Compressor to servers configured to reject HTTP requests that don't include a User-Agent were failing. A User-Agent is now always used in all requests. Props @jaswsinc. See [Issue #49](https://github.com/websharks/html-compressor/issues/49).
+- **Minimum Required PHP Version Bumped to PHP v5.3.2+:** The minimum PHP version required for ZenCache has been bumped up to PHP v5.3.2+ (from PHP v5.3+). The ZenCache cache locking mechanism, specifically the use of `flock()`, requires behavior introduced in PHP v5.3.2. [Issue #444](https://github.com/websharks/zencache/issues/444).

-- **SECURITY FIX - Please upgrade immediately**: Fixes a security related to cached cookies sent in the header of a request. This only affects sites running plugins that might send cookie data via the header. See [#253](https://github.com/websharks/quick-cache/issues/253)
-- **Enhancement**: Auto-Purge RSS Feeds. Quick Cache will now automatically purge the cache for RSS/RDF/Atom Feeds when Feed Caching is enabled. This new option will purge the cache for the master feed, the master comments feed, feeds associated with comments on a Post/Page, term-related feeds (including mixed term-related feeds), and author-related feeds when you update a Post/Page, approve a Comment, or make other changes where Quick Cache can detect that certain types of Feeds should be purged. See [#182](https://github.com/websharks/quick-cache/issues/182)
-- **Enhancement**: Improve handling of symlink creation for 404 cache files by using atomic symlink creation to decrease the possibility of encountering a race condition. See [#242](https://github.com/websharks/quick-cache/issues/242).
-- **Enhancement**: Improved portability of `advanced-cache.php`. This will help reduce configuration overhead for site owners when migrating a WordPress installation from one server to another. See [#258](https://github.com/websharks/quick-cache/issues/258).
-- **Enhancement**: Option Panels now have proper HTML anchor tags so that they work better with browser extensions that rely on anchor tags being available. See [#260.](https://github.com/websharks/quick-cache/issues/260)
-- **Enhancement**: The Plugin Deactivation Safeguards option has been renamed to Plugin Deletion Safeguards. When Plugin Deletion Safeguards are disabled, deactivating and deleting the plugin will now erase your options for the plugin, erase directories/files created by the plugin, remove the advanced-cache.php file, terminate CRON jobs, etc. It completely erases itself, but only when you disable Plugin Deletion Safeguards (enabled by default to prevent accidental loss of data). See [#261](https://github.com/websharks/quick-cache/issues/261).
-- **Enhancement (Pro)**: HTML Compressor now includes FOPEN as transport layer fallback in case cURL is not available. See [#15](https://github.com/websharks/html-compressor/issues/15)
-- **Enhancement (Pro)**: HTML Compressor now writes files atomically; this will help avoid race conditions when writing cache files. See [#273](https://github.com/websharks/quick-cache/issues/273)
-- **Enhancement (Pro)**: Improved error handling for the Auto-Cache Engine. There were some scenarios where `XMLReader()` would fail with a PHP Warning notice when it was unable to properly parse the sitemap. See [#250](https://github.com/websharks/quick-cache/issues/250).
-- **Bug Fix**: The cache directory is now properly removed when deleting the plugin from the WordPress Dashboard plugins list. See [#261](https://github.com/websharks/quick-cache/issues/261).
-- **Bug Fix**: WooCommerce compatibility fix for a bug where cart session data appeared to get cached across sessions. See [#253](https://github.com/websharks/quick-cache/issues/253)
-- **Bug Fix (Pro)**: The plugin upgrade notice no longer appears on Child Blogs in a Multisite Network. There was no security risk here; while the upgrade notice was shown, Child Blog admins who did not have permission to upgrade Network-activated plugins were unable to do anything with the message. See [#259](https://github.com/websharks/quick-cache/issues/259).
-- **Bug Fix (Pro)**: Fixed a bug where, in certain scenarios, a WordPress Plugin may break the JavaScript that controls the Clear Cache button on the Dashboard. See [#272](https://github.com/websharks/quick-cache/issues/259).
-- **Bug Fix (Pro)**: CSS files are now excluded from compression by the HTML Compressor when included inside conditional comments. See [#35](https://github.com/websharks/html-compressor/issues/35)
-- **Bug Fix (Pro)**: HTML Compressor now preserves whitespace inside CSS `calc()` statements. See [#286](https://github.com/websharks/quick-cache/issues/286).

-- **Enhancement**: Improved overall performance by optimizing the auto-purge routines. See also: [#130](https://github.com/websharks/quick-cache/issues/130)
-- **Enhancement**: The "GET Requests" UI Panel now explains that you can use `?qcAC=0` to disable caching when you ARE caching GET Requests. See also: [#210](https://github.com/websharks/quick-cache/issues/210).
-- **New Pro Feature: Auto-Purge XML Sitemaps**. If you're generating XML Sitemaps with a plugin like Google XML Sitemaps, you can now tell Quick Cache to automatically purge any cached sitemap files whenever it purges a Post/Page cache. You may also specify a list of XML Sitemap patterns to clear, if you have multiple sitemap files. See also: [#169](https://github.com/websharks/quick-cache/issues/169)
-- **Enhancement (Pro)**: The Quick Cache Pro Updater now accepts a License Key in place of the WebSharks password.
-- **Enhancement (Pro)**: In a Multisite Network, the Auto-Cache Engine will now also auto-cache each child blog. See also: [#169](https://github.com/websharks/quick-cache/issues/169)
-- **Bug Fix**: Fixed a bug that was causing unapproved, spam, and trash comments to unnecessarily purge the cache. See also: [#159](https://github.com/websharks/quick-cache/issues/159)
-- **Bug Fix**: A custom `WP_CONTENT_DIR` is now obeyed in the scenario where it's set to a path outside of `ABSPATH`. See also: [#95](https://github.com/websharks/quick-cache/issues/95)
-- **Bug Fix**: The UI now correctly displays custom `WP_CONTENT_DIR` in the "Directory/Expiration Time" options panel. See also: [#206](https://github.com/websharks/quick-cache/issues/206)
-- **Bug Fix**: Quick Cache LITE now correctly sets the `QUICK_CACHE_PRO` constant to false. See also: [#229](https://github.com/websharks/quick-cache/issues/229)
-- **Bug Fix**: Workaround for broken page navigation on the front page of some sites. This is a WordPress `redirect_canonical()` bug workaround. See also: [#209](https://github.com/websharks/quick-cache/issues/209)
-- **Bug Fix (Pro)**: 404 Caching now properly returns a 404 HTTP Status code when serving a cached 404 page. See also: [#197](https://github.com/websharks/quick-cache/issues/197)
-- **Bug Fix (Pro)**: The HTML Compressor now properly preserves `[]` character whitespace during CSS compression. See also: [#25](https://github.com/websharks/html-compressor/issues/25)
-- **Bug Fix (Pro)**: The Pro Updater upgrade link now points to the correction location when displayed from a Child Blog in a Multisite Network. See also: [#205](https://github.com/websharks/quick-cache/issues/205)
-- **Bug Fix (Pro)**: The Auto-Cache Engine now correctly handles the sitemap when `home_url()` differs from `site_url()`.
-- **Bug Fix (Pro)**: The "Dynamic Version Salt" options panel now correctly displays the last saved value. See also: [#231](https://github.com/websharks/quick-cache/issues/231)

-- **New Feature**: Branched Cache Structure. Cache files are now written to the cache directory using a more intuitive format of `PROTOCOL`/`HOSTNAME`/`PERMALINK` (e.g., `http/example-com/sample-page.html`). For more details, please see <https://github.com/WebSharks/Quick-Cache/wiki/Branched-Cache-Structure>
-- **New Feature**: 404 Page caching. It's now possible to enable/disable the caching of 404 requests. Enabling this feature generates a single cache file for your 404 Page and then symlinks future 404 requests to that cache file. See *Dashboard -> Quick Cache -> Plugin Options -> 404 Requests*.
-- **New Feature (Pro)**: HTML Compressor (experimental). This new experimental feature automatically combines and compresses CSS/JS/HTML code. See *Dashboard -> Quick Cache -> Plugin Options -> HTML Compressor*. For more details about how this feature works, please see <https://github.com/WebSharks/HTML-Compressor>
-- **New Feature (Pro)**: Auto-Cache Engine. When enabled, the Auto-Cache Engine will pre-cache your site at 15-minute intervals, rebuilding cache files when necessary (it will not rebuild cache files until they have expired). This helps eliminate the slowness a user may experience when visiting a page on your site that has not yet been cached. See *Dashboard -> Quick Cache -> Plugin Options -> Auto-Cache Engine*.
-- **New Feature**: Auto-Purge "Author Page". When a single Post/Page is changed in some way, Quick Cache can also purge any existing cache files for the associated Author Page. See *Dashboard -> Quick Cache -> Plugin Options -> Clearing the Cache*. (This option is enabled by default; disabling this requires Quick Cache Pro.)
-- **New Feature**: Auto-Purge "Category Archives". When a single Post/Page is changed in some way, Quick Cache can also purge any existing cache files for the associated Category archive views. See *Dashboard -> Quick Cache -> Plugin Options -> Clearing the Cache*. (This option is enabled by default; disabling this requires Quick Cache Pro.)
-- **New Feature**: Auto-Purge "Tag Archives". When a single Post/Page is changed in some way, Quick Cache can also purge any existing cache files for the associated Tag archive views. See *Dashboard -> Quick Cache -> Plugin Options -> Clearing the Cache*. (This option is enabled by default; disabling this requires Quick Cache Pro.)
-- **New Feature**: Auto-Purge "Custom Term Archives". When a single Post/Page is changed in some way, Quick Cache can also purge any custom Terms that may have their own Term archive views. See *Dashboard -> Quick Cache -> Plugin Options -> Clearing the Cache*. (This option is enabled by default; disabling this requires Quick Cache Pro.)
-- **Enhancement**: Improved conflict handling of other plugins using `ob_start()`. See <https://github.com/WebSharks/Quick-Cache/issues/97>
-- **Enhancement**: Added a postload filter for `status_header` so that Quick Cache can properly detect calls to the WP core function `status_header()`
-- **Enhancement**: The Quick Cache cache directory has been changed to `wp-content/cache/quick-cache/` to provide better organization of cache files and avoid interfering with another plugin that may also be writing to the `wp-content/cache/` directory. See <https://github.com/WebSharks/Quick-Cache/issues/123>
-- **Enhancement**: New detailed debugging notes (see *Dashboard -> Quick Cache -> Plugin Options -> Enable/Disable*). There is now an extra option to show detailed debugging information in addition to the Quick Cache notes in the HTML source. For now, this feature only applies when the HTML Compressor is enabled.
-- **Enhancement**: Better Debugging Notices. If Quick Cache is not caching a particular page (such as when a logged-in user visits the site and logged-in user caching is not enabled), Quick Cache will now report why that page is not being cached in the HTML notes.
-- **Enhancement**: Improved compatibility with the Nav Menu Roles plugin. See <https://github.com/WebSharks/quick-cache/issues/164>
-- **Bug Fix**: Obey custom content directories. If you have customized your `WP_CONTENT_DIR` and `WP_CONTENT_URL` constants to point somewhere other than the default, Quick Cache will now obey those and use your custom directory for storing cache files. See <https://github.com/WebSharks/Quick-Cache/issues/95>
-- **Bug Fix**: Scheduled posts now trigger the clearing of any associated archive views when those posts go live (assuming you have those archive views set to Auto-Purge in *Dashboard -> Quick Cache -> Plugin Options -> Clearing the Cache*). See <https://github.com/WebSharks/Quick-Cache/issues/26>
-- **Bug Fix**: Fixed a bug where saving a post as `draft` would trigger the Auto-Purge Post routine and clear the cache for that post. Now only purges post status `publish` and `private` and when transitioning from `publish` or `private` post status to `draft`, `future`, or `private`. See <https://github.com/WebSharks/Quick-Cache/issues/43>
-- **Bug Fix**: Split/paginated comments and multi-page Posts/Page cache files are now purged properly when the post cache is purged. See <https://github.com/WebSharks/Quick-Cache/issues/75>
-
-= v140104 =
-
-* **New Options for Feed Caching**. It's now possible to control RSS, RDF, and Atom Feed caching. The new default is for feed caching to be disabled, which resolves an issue where new posts don't show up in the feed until the cache is cleared.
