-- Added AST version 60 with the following changes:
-  - `AST_FUNC_DECL` and `AST_METHOD` no longer generate a `uses` child. Previously this child was
-    always `null`.
-  - `AST_FUNC_CONST_ELEM` now always has a `docComment` child. Previously it was absent on PHP 7.0.
-    On PHP 7.0 the value is always `null`.
-- Added `ARRAY_ELEM_REF` flag, which is used by `AST_ARRAY_ELEM` for by-reference array elements
-  and (since PHP 7.3) for by-reference destructuring. Previously this flag was represented simply
-  by the value `1`.
-- Deprecated AST versions 40 and 45.
-- Fix build against PHP 7.4-dev.
+- TBD
