+- Adding new config option: `amp_exclusions_enable` (default is enabled). This improves compatibility with [Accelerated Mobile Pages](https://www.ampproject.org/). When this option is enabled and the URI being compressed ends with `/amp/`, or the document contains a top-level `` tag (`` is accepted as well), then features which are incompatible with [Accelerated Mobile Pages](https://www.ampproject.org/) will be disabled accordingly, regardless of your other settings. See [Issue #695](https://github.com/websharks/comet-cache/issues/695) in the Comet Cache repo.
+- Adding `isDocAmpd()` conditional check against current URI & document.
+- Adding automatic AMP feature exclusions for improved AMP compatibility.
+- Optimizing for speed by removing unnecessary calls to `unset()`.
+- Enhancing unicode compatibility by taking full advantage of all `mb_*()` functions.
+- Adding multibyte compatible `pregQuote()`.
+- Adding multibyte compatible `replaceOnce()`.
+- Adding multibyte compatible `substrReplace()`.
+- Updating all regex patterns to add the `/u` flag for unicode compatibility.
+- Updating minimum PHP requirement. Now requires PHP v5.4+ in support of short array syntax `[]`.
