iTop/lib/doctrine/lexer/UPGRADE.md

Note about upgrading: Doctrine uses static and runtime mechanisms to raise awareness about deprecated code.

• Use of @deprecated docblock that is detected by IDEs (like PHPStorm) or Static Analysis tools (like Psalm, phpstan)
• Use of our low-overhead runtime deprecation API, details: https://github.com/doctrine/deprecations/

Upgrade to 3.0.0

Doctrine\Common\Lexer\Token no longer implements ArrayAccess. Parameter type declarations have been added to Doctrine\Common\Lexer\AbstractLexer and Doctrine\Common\Lexer\Token. You should add both parameter type declarations and return type declarations to your lexers, based on the @return phpdoc.

Upgrade to 2.0.0

AbstractLexer::glimpse() and AbstractLexer::peek() now return instances of Doctrine\Common\Lexer\Token, which is an array-like class Using it as an array is deprecated in favor of using properties of that class. Using count() on it is deprecated with no replacement.
