CHANGELOG.md

@@ -4,6 +4,51 @@ All notable changes to `pdf-tools` are documented here.
 
 The project follows a pragmatic versioning scheme while the app is still below `1.0.0`: minor versions mark coherent user-facing milestones; patch versions mark fixes and small improvements.
 
+## 0.4.4 — LocalToolBox organization migration
+
+### Changed
+
+- Moved canonical repository, Toolbox schema, corresponding-source, and package-registry URLs from the personal `zemion` namespace to the `lotobo` LocalToolBox organization.
+- Upgraded the Toolbox contract, React shell, and validation testkit to `0.2.3` from the organization-owned registry.
+- Bumped the app/package version to `0.4.4`.
+
+## 0.4.3 — Aligned Toolbox content width
+
+### Changed
+
+- Expanded the PDF workspace's maximum content width from `900px` to `90rem` so it aligns with the shared Toolbox shell bar and central catalogue.
+- Bumped the app/package version to `0.4.3`.
+
+## 0.4.2 — Corrected Toolbox header orientation
+
+### Changed
+
+- Upgraded the Toolbox contract, React shell, and validation testkit to `0.2.2`.
+- Moved the Toolbox icon and `add·ideas Toolbox` label to the fixed far-left block, kept the app title and one tagline centered, and moved the fixed control cluster to the far right in the reverse order: Help, the PDF-specific Gitea source link, Apps, and Personalize.
+- Bumped the app/package version to `0.4.2`.
+
+## 0.4.1 — Stable Toolbox header layout
+
+### Changed
+
+- Upgraded the Toolbox contract, React shell, and validation testkit to `0.2.1`.
+- Adopted the stable shared top bar: the fixed left cluster contains Personalize, Apps, the PDF-specific Gitea source link, and Help; the app title and one tagline remain centered; and the fixed far-right block contains the Toolbox icon and `add·ideas Toolbox` label.
+
+## 0.4.0 — Shared Toolbox header and themes
+
+### Added
+
+- Added the standard Toolbox header controls for in-app help, the app-specific Gitea source link, appearance personalization, and application switching.
+- Added explicit light, dark, and system-following themes for the PDF workspace, saved-workspace list, merge queue, dialogs, status messages, and controls.
+
+### Changed
+
+- Upgraded the Toolbox contract, React shell, and validation testkit to `0.2.0`.
+- The header now uses the manifest's repository metadata for the source link instead of carrying a release-specific source action.
+- Replaced application color literals with semantic PDF workspace variables while intentionally keeping rendered PDF pages on a white paper surface.
+- Scoped application button and card styles to the shell's main content so they cannot override shared header controls.
+- Bumped the app/package version to `0.4.0`.
+

 - **Merge choices**: Loading another PDF can replace the current document, append pages, or insert pages at a chosen position.
