-## [0.5.2] - 2026-01-22
+## [Unreleased]
 
-### Fixed
-- Fixed COMMAND rules promise handling to properly update queue status
-  - When an agent provides a promise tag for a FAILED command rule, the queue entry is now correctly updated to SKIPPED status
-  - Previously, FAILED queue entries remained in FAILED state even after being acknowledged via promise
-  - This ensures the rules queue accurately reflects rule state throughout the workflow
-
-## [0.5.1] - 2026-01-22
-
-### Fixed
-- Fixed quality criteria validation logic in skill template (#111)
-  - Changed promise condition from AND to OR: promise OR all criteria met now passes
-  - Changed failure condition from OR to AND: requires both criteria NOT met AND promise missing to fail
-  - This corrects the logic so the promise mechanism properly serves as a bypass for quality criteria
-
-## [0.5.0] - 2026-01-20
+### Added
 
 ### Changed
-- **BREAKING**: Renamed `document_type` to `doc_spec` throughout the codebase
-  - Job.yml field: `document_type` → `doc_spec` (e.g., `outputs: [{file: "report.md", doc_spec: ".deepwork/doc_specs/report.md"}]`)
-  - Class: `DocumentTypeDefinition` → `DocSpec` (backward compat alias provided)
-  - Methods: `has_document_type()` → `has_doc_spec()`, `validate_document_type_references()` → `validate_doc_spec_references()`
-  - Template variables: `has_document_type` → `has_doc_spec`, `document_type` → `doc_spec`
-  - Internal: `_load_document_type()` → `_load_doc_spec()`, `_doc_type_cache` → `_doc_spec_cache`
 
-### Added
-- Comprehensive tests for generator doc spec integration (9 new tests)
-  - `test_load_doc_spec_returns_parsed_spec` - Verifies doc spec loading
-  - `test_load_doc_spec_caches_result` - Verifies caching behavior
-  - `test_load_doc_spec_returns_none_for_missing_file` - Graceful handling of missing files
-  - `test_generate_step_skill_with_doc_spec` - End-to-end skill generation with doc spec
-  - `test_build_step_context_includes_doc_spec_info` - Context building verification
+### Fixed
 
-### Migration Guide
-- Update job.yml files: Change `document_type:` to `doc_spec:` in output definitions
-- Update any code importing `DocumentTypeDefinition`: Use `DocSpec` instead (alias still works)
-- Run `deepwork install` to regenerate skills with updated terminology
