The file documents changes to the PHP_CodeSniffer project for the 4.x series of releases.

## [4.0.1] - 2025-11-10

This release includes all improvements and bugfixes from PHP_CodeSniffer [3.13.5].

### Added
- Runtime support for PHP 8.5. All known PHP 8.5 deprecation notices have been fixed.
- Syntax support for new PHP 8.5 features will follow in a future release.
- If you find any PHP 8.5 deprecation notices which were missed, please report them.

### Changed
- The Squiz.ControlStructures.SwitchDeclaration sniff will now flag a PHP close tag as a "wrong opener" and will auto-fix this by inserting a colon. [#1316]
- Various housekeeping, including improvements to the tests and documentation.

### Fixed
- 4.x regression [#1277]: bring back whitespace tolerance in `phpcs:ignore` comma-separated rule reference lists.
- Note: this bug did not affect `phpcs:disable`/`phpcs:enable` ignore annotations.
- Fixed bug [#968]: Generic.WhiteSpace.ScopeIndent was reporting false positives - and making incorrect fixes - for lines following a line containing an arrow function.
- Thanks to [Soichi Sato][@Soh1121] for the patch.
- Fixed bug [#1216]: Tokenizer/PHP: added more defensive coding to prevent PHP 8.5 "Using null as an array offset" deprecation notices.
- Thanks to [Andrew Lyons][@andrewnicols] for the patch.
- Fixed bug [#1279]: Tokenizer/PHP: on PHP < 8.0, an unclosed attribute (parse error) could end up removing some tokens from the token stream.
- This could lead to false positives and false negative from sniffs, but could also lead to incorrect fixes being made mangling the file under scan.
- Fixed bug [#1315]: Squiz.ControlStructures.SwitchDeclaration: a number of the fixers would get into fixer conflicts with each other if the code under scan contained multiple statements on a line within a `switch`.
- The sniff will now forbid - and auto-fix - multiple statements on one line for `case`/`default` and "case breaking" statements.
- Fixed bug [#1316]: Tokenizer/PHP: a PHP close tag after a `switch` case condition or after a `default` keyword, was not regarded as a "scope_opener" for the `case`/`default` body.
- Fixed bug [#1316]: PSR2.ControlStructures.SwitchDeclaration: the `WrongOpener` error is now also auto-fixable if the wrong opener is a PHP close tag.
- Fixed bug [#1316]: Squiz.PHP.NonExecutableCode would throw false positives when code within a switch control structure would move in and out of PHP.
