-### Added
+#### docs
+- Deduplicate TSV schema docs by generating tables from code constants, add CI/pre-commit drift checks, and extend documentation automation with docs-touch/changelog gates, Release Drafter, and Read the Docs tag triggers. (#51)- Improve documentation automation and TSV schema generation. (#52)- Document PR-based releases (`scripts/release_prepare.py`, **CD - Prepare release PR** workflow), maintainer `docs/releasing.rst`, and Sphinx generated-dir guidance (`_autosummary`, `_generated`, `_static`, `_templates`). (#55)#### changed
+- Ship ``0.4.0a1`` alpha, space-free data/install paths (``WyssCenter`` / ``DBSAnnotator``), optional GitHub release update checks, upgrade-safe user config locations, and ``release_prepare.py --bump`` for prerelease and semver bumps. (#62)- Update checker compares all published GitHub releases for the highest applicable newer semver (including pre-releases), handles repos with no releases quietly, surfaces pre-release guidance with support links, and lets users turn off automatic update checks from Help or the notification. (#63)- Consolidate branding under `icons/logosimple/` for Briefcase and Qt, add `scripts/build_app_icons.py` to generate platform icon sizes from a single source PNG, and document Linux `linux system` icon requirements. (#66)### Added
 - Initial changelog scaffold following Keep a Changelog 1.1.0.
