 ## [Unreleased]
+### Added
+- `phpCodeSniffer.specialOptions` option to allow for supporting narrow use-cases without
+needing to add options that most users will not need.
+- `phpCodeSniffer.specialOptions.phpcsIntegrationPathOverride` option that allows for
+overriding the path to the directory containing the extension's PHPCS integration.
