+### Added

+- Support for defining schemas as dicts (in addition to the class-based approach)
+- New `disabled_actions` graph configuration to prevent specific actions from being generated
+
+### Changed
+
+- BREAKING CHANGE: Converted parameter schema from voluptuous to msgspec
+
+### Fixed
+
+- `taskgraph full -J --tasks <regex>` now displays full dependencies instead of a filtered subset
+- `fetch-content` now percent-encodes artifact names, fixing downloads of artifacts containing spaces or other special characters
+
