v0.5.1

Fixed

• Replace recursive derivation-tree inspection, validation, cloning, dictionary conversion, comparison, and representation with iterative traversal, preserving finite-tree results and the existing nested dictionary format.
• Replace nested default iteration and recursive k-path helpers with explicit traversal stacks, preserving seeded outputs and coverage accounting.

v0.5.0

Warning: Breaking changes to the public interface.

Added

• Grammar.validate() raises ValueError for invalid grammars and returns None otherwise.
• SyntaxSymphony.fuzz_tree() generates complete trees, replacing tree_fuzz().

Fixed

• Reject grammars with rules that cannot finish and fix rule selection for recursive grammars.

Changed

• Fuzzers keep their own copy of the grammar. Create a new fuzzer to use edited rules.

Removed

• Internal helpers are now private, and seen arguments are removed. See the migration guide.

v0.4.3

Added

• scripts/extract_release_notes.py to extract Keep a Changelog sections for GitHub Releases; unit tests in tests/test_release_notes.py.

Changed

• Publish workflow populates GitHub Release notes from CHANGELOG.md via --notes-file instead of empty --notes.
