 ## [Unreleased]
 
+[Squizlabs/PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer) is dead. Long live [PHPCSStandards/PHP_CodeSniffer](https://github.com/PHPCSStandards/PHP_CodeSniffer)!
+
+### Breaking Changes
+- The `squizlabs/PHP_CodeSniffer` repository has been abandoned. This repository will serve as the continuation of the project.
+    - Composer users will need to `require-dev` the `phpcsstandards/php_codesniffer` package instead.
+    - PHIVE users may need to clear the PHIVE URL cache.
+        - PHIVE users who don't use the package alias, but refer to the package URL, will need to update the URL from `https://squizlabs.github.io/PHP_CodeSniffer/phars/` to `https://phars.phpcodesniffer.com/phars/`.
+    - Users who download the PHAR files using curl or wget, will need to update the URL from `https://squizlabs.github.io/PHP_CodeSniffer/[phpcs|phpcbf].phar` to `https://phars.phpcodesniffer.com/[phpcs|phpcbf].phar`.
+    - Installation of PHP_CodeSniffer via PEAR is no longer supported.
+        - Note: this does not affect the PEAR sniffs.
+
 ### Added
 - Added support for readonly classes to File::getClassProperties() through a new is_readonly array index in the return value
     - Thanks to Juliette Reinders Folmer (@jrfnl) for the patch
