- Behavioral: Modifications made in grammar do not affect parser, which was created before those modifications.
- Deprecation: Old ways to construct Grammars were marked as deprecated - use Builders instead.
- If you extend "org.sonar.sslr.toolkit.AbstractConfigurationModel", then make sure to override method "getCharset".
- Migration to new Grammar API is highly recommended, because most likely old API will be marked as deprecated in next release and fully removed later. Tip on migration: create new grammar (all tests pass as they don't depend on this grammar), migrate tests for grammar (they should pass), migrate the rest (AST Visitors and so on).
