3.7.0

PHP 8.1 Language Feature Support

PHP_CodeSniffer has run correctly under PHP 8.1 since PHP 8 support was added, but it has not supported new 8.1 language features until this release. Version 3.7.0 adds support for the following PHP 8.1 language features:

• Enums
• Explicit octal notation
• Readonly properties
• Intersection types
• The never type

Note: Standards and sniffs included with PHP_CodeSniffer have been updated to support these language features, but external standards and sniffs may need updating before they are able to detect them correctly.
