+## [1.7.38] - 2026-05-29
+
+### Fixed
+
+- **SABnzbd History Legacy Slot Name Compatibility (Issue #74)** — Hardened SABnzbd active-download and history slot title matching in `DownloadMatcher.js` to support all slot name property variations (`filename`, `nzbname`, `name`, `nzb_name`). This ensures history matching succeeds against cached/legacy data schemas where the name is stored solely under the `filename` property, preventing completed downloads awaiting import from incorrectly displaying as `"Unknown"` client cards. Added unit tests for legacy `filename` slot matching compatibility.
+
+## [1.7.37] - 2026-05-29
+
+### Fixed
+
+- **SABnzbd History Matching Symmetry (Issue #74)** — Consolidated SABnzbd active-download matching algorithms in `DownloadMatcher.js` by introducing a unified, type-safe internal helper `findSabMatch(sabDownloadId, nzbName, context, caller)`. Refactored `matchSabSlots` and `matchSabHistory` to route entirely through `findSabMatch`. This resolves a bug where completed SABnzbd downloads awaiting manual import in Sonarr or Radarr queues were incorrectly flagged as "unknown" client/"Orphaned (unconfigured client)". Added detailed unit tests to safeguard this behavior.
+
+## [1.7.36] - 2026-05-29
+
+### Fixed
+
+- **Test Timeout & Cross-Suite Background Event Pollution (V8 Coverage)** — Configured `fileParallelism: false` and `testTimeout: 15000` in `vitest.config.js`. This guarantees that slow code compilation/instrumentation under V8 coverage doesn't cause transient 5-second timeouts, and prevents asynchronous fire-and-forget background event loops (like Ombi webhook retry loops) in one test suite from running concurrently and overwriting cache singletons in other test suites.
+
+## [1.7.35] - 2026-05-29
+
+### Added
+
+- **Orphaned *arr Queue Item Support (Issue #73)** — Added support for active Sonarr/Radarr queue items from unconfigured download clients ("orphaned" downloads). Added a new synthetic client (`'orphaned'`) with a custom viewBox vector graphics asset at `/images/clients/orphaned.svg` to represent unconfigured clients, and updated filter dropdown lists and active downloads grids to cleanly display them with a dimmed logo, custom dashed border styling, and informative hover tooltips. Resolves Gitea Issue [#73](https://git.i3omb.com/Gandalf/sofarr/issues/73).
+
+### Enhanced
+
+- **Download Matching & JSDoc Hygiene (Issue #73)** — Refactored core active-download matching algorithms into unified, deduplicated helper functions (`normalizeTitle`, `titleMatches`, `buildArrDownload`) in `DownloadMatcher.js`, preventing hundreds of lines of duplicate code. Handled case-insensitive and type-safe `downloadId` lookup in `matchSabHistory` across both history and active queue records. Added safe progress arithmetic bounds checking to prevent division-by-zero or `NaN`.
+
+### Fixed
+
+- **Security Metadata Isolation in buildArrDownload (Issue #73)** — Restricted access control for sensitive properties like `arrInstanceKey` (the raw instance API key) to ensure they are strictly stripped out of download objects for non-administrator users, preserving system security boundaries.
+
+## [1.7.34] - 2026-05-28
+
+### Fixed
+
+- **Webhook Test Duplicate Error (Issue #71)** — Skipped duplicate/replay protection for `"Test"` event types in Sonarr and Radarr webhook handlers, resolving test button failures. Resolves Gitea Issue [#71](https://git.i3omb.com/Gandalf/sofarr/issues/71).
+
+### Enhanced
+
+- **Unified Tab Header Layout & Typography Consistency (Issue #72)** — Added consistent titles, subtitles, and icons across Active Downloads, Recently Completed, and Requests tab panels, and refactored styling to use a unified flexbox design with CSS variables. Resolves Gitea Issue [#72](https://git.i3omb.com/Gandalf/sofarr/issues/72).
