+### Changed
+- Updated the version constraints for [PHP_CodeSniffer] to `^3.13.3 || ^4.0.0` (was `^3.6.2`).
+- Updated the version constraints for [PHPCompatibility] to `^10.0.0@dev` to benefit from hugely improved issue detection.
+    Includes excluding a number of additional error codes from the `PHPCompatibility.Constants.NewConstants` sniff to allow for polyfilled PHP tokens.
+- The `PSR12.ControlStructures.BooleanOperatorPlacement` will now enforce that boolean operators between two conditions on different lines will always be at the start of the second line.
+- The `PPSR12.Files.FileHeader.SpacingAfterTagBlock` error code (PHPCS 4.0+) has been excluded to allow for file docblocks to directly follow a PHP open tag at the top of a file.
+- The `PEAR.Commenting.FileComment.DuplicateSinceTag` error code has been excluded to allow for `@since` tags used as a changelog in file docblocks.
+- Various housekeeping, including a contribution from [@fredden].
