+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 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.
