We are very pleased to announce the release of the ApiDoc extension version 4.0.0.

This is a major release that modernizes ApiDoc for current PHP projects. The minimum PHP version is now 8.2, and dependency requirements were raised for nikic/php-parser, phpdocumentor/reflection, and phpdocumentor/type-resolver.

Version 4.0.0 adds support for intersection and nullable types, PHPStan/Psalm syntax, constants in interfaces and traits, inherited descriptions, improved method signatures, better inline @see and @link handling, and links to built-in PHP functions. It also includes a new template for custom projects.

A brief overview of major changes:

• PHP 8.2 is now required.
• Deprecated code was removed.
• nikic/php-parser 5.0+ is now required.
• phpdocumentor/reflection 7.0+ and phpdocumentor/type-resolver 2.0+ are now required.
• FQSEN support in inline @link tags was removed.
• Type extraction and rendering were significantly improved.
• Constants, inheritance, and PHPDoc handling are more complete.

Most of this release is handled by Maksim Spirkov, with the new custom project template also based on work by jcherniak and cebe.
