Cache is not automatically cleared when widgets are changed #411
Steps to reproduce this bug
The entire cache should be cleared, since a change to widgets may affect many pages on the site.
No cache files are cleared. The old cache file continues to be presented to users and the changes to widgets are not seen until the cache is cleared manually.

…arance → Widgets** are added/edited/removed, and Comet Cache will automatically clear the cache so that your site remains up-to-date. See [Issue #411](wpsharks/comet-cache#411).
- **Bug Fix:** Improving PHP OPcache detection. Now considering the INI option `opcache.restrict_api`. Comet Cache is now smart enough to avoid generating the PHP Warning: _PHP Warning: Zend OPcache API is restricted by "restrict_api" configuration directive_. See [Issue #733](#733). - **New Feature (Pro): Mobile Mode.** This release adds a new feature that is designed to improve compatibility with Adaptive themes for mobile devices. To learn more, please see: **Dashboard → Comet Cache Pro → Plugin Options → Mobile Mode**. See also: [Issue #471](#471). - **Enhancement: Auto-Clearing Author Page Cache.** This release makes Comet Cache smart enough to detect when a user is deleted (or removed from a child blog in a Network), at which time the Author page for that user will be cleared from the cache so it can be regenerated automatically. See [Issue #304](#304). - **Enhancement: Multibyte Compatibility.** This release improves support for WordPress Permalinks that contain UTF-8 symbols (or emojis) in them. More specifically, this release adds the `/u` flag to all `preg_*()` calls in cache clearing routines that generate cache paths from Watered-Down Regex patterns entered by a site owner. See: [Issue #611](#611). - **Enhancement: Widget Change Detection.** Comet Cache can now detect when **Appearance → Widgets** are added/edited/removed, and Comet Cache will automatically clear the cache so that your site remains up-to-date. See [Issue #411](#411). - **Enhancement (Pro): Static CDN Filters and `srcset`.** This release enhances Static CDN Filters in Comet Cache Pro. Static CDN Filters are now smart enough to filter all image sources included in an `srcset=""` attribute that is generated by WordPress. See [Issue #660](#660). If you'd like to learn more about `srcset=""`, see [this article at WordPress.org](https://make.wordpress.org/core/2015/11/10/responsive-images-in-wordpress-4-4/). - **Enhancement (Pro): Automatic Background Updates.** It is now possible to enable automatic background updates that occur quietly in the background whenever new features, bug fixes, or security issues are addressed by our developers. See: **Dashboard → Comet Cache Pro → Config. Options → Update Credentials**. See also: [Issue #827](#827). - **Enhancement (Pro): HTML Compressor + Accelerated Mobile Pages (AMP).** Updated to the latest available release of the HTML Compressor (v161208) with improved support for [Accelerated Mobile Pages](https://www.ampproject.org/). See: [Issue #695](#695). See also: [HTML Compressor v161208 changelog](https://github.com/websharks/html-compressor/releases/tag/161208). - **Enhancement (Pro): HTML Compressor / AMP Compatibility.** Improved compatibility with [Accelerated Mobile Pages](https://www.ampproject.org/). There is a new HTML Compressor option that is enabled by default and it makes Comet Cache smart enough to auto-detect and selectively disable portions of the HTML Compressor that are incompatible with the AMP spec; i.e., routines that are not necessary when serving APMd pages. In short, if the URI being compressed ends with `/amp/`, or the document contains a top-level `<html
⚡>` tag (`<html amp>` is accepted as well), then features which are incompatible with [Accelerated Mobile Pages](https://www.ampproject.org/) will be disabled accordingly. - **Compatibility:** Avoid deprecated `wp_get_sites()` and use `get_sites()` instead. See [Issue #848](#848). - **Documentation:** Added Watered-Down Regex documentation notes to the inline documentation (in the software) about the use of `^` and `$` in some places where these special characters are not fully supported. Also adding the same notes to the [Watered-Down Regex KB Article](https://cometcache.com/r/watered-down-regex-syntax/). See also: [Issue #611](#611).
