+## [1.7.32] - 2026-05-28
+
+### Fixed
+
+- **TransmissionClient Hardening (Issue #63)** — Mapped the previously-unknown Transmission RPC status code `7` to `Checking` (best-effort; the RPC spec formally documents only codes 0–6, and the historical alias `TORRENT_IS_CHECKING` corresponds to code 2), so torrents reporting code 7 are now rendered with a useful status label instead of `Unknown`. Implemented three torrent control methods on `TransmissionClient` that were previously absent: `startTorrent(id)` (resumes via `torrent-start`), `stopTorrent(id)` (pauses via `torrent-stop`), and `removeTorrent(id, deleteData = false)` (removes via `torrent-remove`, optionally also deleting local files via Transmission's `delete-local-data` flag). All three accept either a single id (numeric or hash) or an array of ids, matching the Transmission RPC contract. Documented in `extractArrInfo()` that an `arrQueueId` cannot reliably be derived from filename alone — the cross-client matching path is hash-based via `DownloadMatcher.matchTorrents()` (Issue #65), which keys on `torrent.hashString` for Transmission. Added regression tests for status code 7 and all three control methods. Resolves Gitea Issue [#63](https://git.i3omb.com/Gandalf/sofarr/issues/63).
+- **Frontend Build Stability (Issue #66)** — Added explanatory inline comments to `client/vite.config.js` documenting two non-standard but deliberate build settings: `build.outDir = '../public'` (the Vite bundle is emitted into the Express-served `public/` directory at the repo root rather than the Vite-default `client/dist/`) and `build.emptyOutDir = false` (required so the hand-authored static assets committed under `public/` are not wiped by every `vite build`). The comments explicitly warn that changing either setting without also updating the Express static-serve configuration in `server/app.js` and the Dockerfile copy steps will break production serving. Removed a stale, untracked `client/dist/` directory (a leftover from an earlier default-Vite build) that was harmless — both `.gitignore` and `.dockerignore` already excluded it from version control and Docker contexts — but caused recurring confusion about which `index.html` was authoritative. Verified `client/index.html` correctly references `/src/main.js` as the Vite entrypoint. Resolves Gitea Issue [#66](https://git.i3omb.com/Gandalf/sofarr/issues/66).
+- **Download Matching & Deduplication (Issue #65)** — `DownloadMatcher.matchTorrents()` now attempts hash-first matching for every torrent before falling back to title-substring matching. The hash lookup compares `torrent.hash` (qBittorrent, rTorrent) or `torrent.hashString` (Transmission) against each *arr* queue/history record's `downloadId`, restoring deterministic matching for renamed downloads and torrents whose on-disk filename has diverged from the *arr* release title. Title-substring matching is retained verbatim as a fallback so unhashed clients and legacy fixtures continue to work. After the per-torrent matching pass, the returned list is deduplicated by the composite key `(arrType, arrQueueId)`: the first matched download wins, so a single torrent that maps to N *arr* queue records sharing one queue id (for example, a season pack exposed as multiple per-episode rows) produces a single dashboard card instead of N near-identical duplicates. A new integration suite at `tests/integration/download-matcher-season-pack.test.js` covers hash-first matching for qBittorrent (`hash`) and Transmission (`hashString`), the title-substring fallback path, and the deduplication step. Resolves Gitea Issue [#65](https://git.i3omb.com/Gandalf/sofarr/issues/65).
+- **qBittorrentClient Peer Data & Response Safety (Issue #64)** — `QBittorrentClient.normalizeDownload()` now exposes two new fields on every torrent record: `seeds` (sourced from qBittorrent's `num_seeds`, the count of connected seed peers) and `peers` (sourced from `num_leechs`, the count of connected leecher peers). The connected counts were chosen deliberately over the swarm totals `num_complete`/`num_incomplete` so the values remain consistent with what other clients (Transmission via `peersConnected`/`peersSendingToUs`, rTorrent via `d.peers_connected`) report on the same normalised contract. `QBittorrentClient.getMainData()` now also defensively returns the existing in-memory torrent map (rather than dereferencing a null) when the qBittorrent server responds with an empty body to `/api/v2/sync/maindata`, eliminating a crash class observed against transiently-restarting qBittorrent instances. A regression test verifies the new fields are populated from `num_seeds`/`num_leechs` and not from the swarm-total fields. Resolves Gitea Issue [#64](https://git.i3omb.com/Gandalf/sofarr/issues/64).
+- **Season Pack Queue Handling & Crash Prevention (Issue #61)** — Extracted a shared `buildArrQueueCache(queues, instances, mediaKey)` helper at `server/utils/arrQueueHelpers.js` covering both Sonarr and Radarr, replacing four previously-divergent inline `flatMap` blocks across the background poller (`server/utils/poller.js`) and the webhook event processor (`server/routes/webhook.js`) that built the `poll:sonarr-queue` and `poll:radarr-queue` cache entries. Sonarr queue records that share a `downloadId` (the canonical fingerprint for a season-pack release) are now annotated with `isSeasonPack: true` and `episodeCount: <n>` so downstream consumers — including the active-downloads matching service — can identify and de-duplicate season packs without re-deriving the grouping. The helper is wrapped in per-record and per-instance `try`/`catch` guards: malformed records (`null`, missing `data`, unknown instance ids) are skipped with a warning rather than throwing, eliminating a class of crashes that previously bubbled out of the `flatMap` and tore down the entire poll cycle or webhook refresh. Movies (Radarr) skip season-pack annotation by design. A new unit test suite at `tests/unit/utils/arrQueueHelpers.test.js` covers tagging, season-pack grouping, null-safety, and unknown-instance fallback. Resolves Gitea Issue [#61](https://git.i3omb.com/Gandalf/sofarr/issues/61).
+- **rTorrent Null-Safety, SABnzbd History Limit & Client Last-Error Visibility (Issue #68)** — Three related hardening improvements to the download-client layer. First, `RTorrentClient` now defends against the malformed-response scenarios observed against misconfigured or transiently-restarting rTorrent servers: `getActiveDownloads()` explicitly checks that `d.multicall2` returned an actual array (logging a warning and returning `[]` if not, rather than throwing on `.map`) and processes each torrent row in its own `try`/`catch` so a single malformed entry cannot poison the whole result set. All eleven field values retrieved from the multicall response are coerced to their expected types via explicit `Number()`/`String()` conversions in `normalizeDownload()`, so downstream arithmetic and string operations can no longer blow up on `null` or `undefined` values from plugins or older rTorrent versions. `_extractArrInfo()` now short-circuits safely on non-string filenames. `getClientStatus()` additionally coerces the global rate values through `Number.isFinite` before returning them. Second, the SABnzbd history limit (previously hard-coded to `10` records per poll) is now configurable via the `SAB_HISTORY_LIMIT` environment variable. Invalid or absent values fall back to the default of `10` with a log warning, ensuring backward compatibility. Third, all four download clients (`RTorrentClient`, `SABnzbdClient`, `QBittorrentClient`, `TransmissionClient`) now record structured `lastError` objects (`{ operation, message, at }`) on every failed API call via `_recordLastError()` and clear them on subsequent success via `_clearLastError()` — both helpers introduced on the `DownloadClient` base class alongside the public `getLastError()` accessor. The per-client last-error is surfaced through `DownloadClientRegistry.getAllClientStatuses()` and exposed on the `GET /api/status/status` admin endpoint under the new `downloadClients` array, letting the admin panel show a per-client failure indicator without log scraping. New regression tests cover all null-safety paths, the SAB history limit env variable (unset, valid, invalid, propagated to the API call), and the full lastError set/clear cycle for both rTorrent and SABnzbd. Resolves Gitea Issue [#68](https://git.i3omb.com/Gandalf/sofarr/issues/68).
+- **Webhook Reliability (Issue #62)** — Hardened the webhook replay protection to prevent false-duplicate detection while preserving protection against genuine retries. The replay key for Sonarr and Radarr now incorporates a content identifier (`downloadId`, falling back to `series.id` or `movie.id`) alongside the existing `eventType:instanceName:eventDate` components, so that multiple distinct events sharing the same timestamp (for example, several `Grab` events fired in the same second for episodes in a season pack) no longer collide and get silently dropped. Events without a content identifier (such as `Test`) fall back gracefully to the previous key shape so existing behaviour is preserved. The Ombi handler — which already uses a distinct `requestId`-bearing key — is unchanged. Additionally, the Sonarr and Radarr handlers now log an explicit warning when the inbound `instanceName` fails to match any configured instance and processing falls back to the first instance, improving diagnosability of misconfigured webhook senders. Resolves Gitea Issue [#62](https://git.i3omb.com/Gandalf/sofarr/issues/62).
+
+## [1.7.31] - 2026-05-28
+
+### Fixed
+
+- **Frontend Connection Remediation** — Staged and committed dynamic proxy target configurations and startup pipeline orchestrations. Rebuilt the production build of `public/app.js` to ensure dynamic SSL bypass and dynamic local network address resolution are fully compiled and deployed.
+
+## [1.7.30] - 2026-05-28
+
+### Added
+
+- **Testing Scope Expansion (Issue #60)** — Significantly expanded unit and integration test coverage targeting the background polling engine, rate limiting, and frontend rendering logic to secure core behaviors.
+  - **Background Poller Tests (`poller.test.js`)**: Implemented robust unit tests verifying concurrency guards, subscriber registries (`onPollComplete`/`offPollComplete`), graceful error recovery, webhook bypasses, and global fallbacks using a hybrid testing approach with Vitest fake timers.
+  - **Isolated Rate Limiting (`rateLimiter.test.js`)**: Designed a dedicated integration test that unsets `SKIP_RATE_LIMIT` and asserts `429 Too Many Requests` responses under rapid login requests while maintaining test suite stability.
+  - **Active Downloads Decoration (`ombiDecoration.test.js`)**: Covered deep-link generation (`arrLink`) for active download matching under admin and non-admin states.
+  - **Frontend UI Rendering (`downloads.test.js`)**: Expanded coverage for the downloads rendering engine, specifically targeting conditional administrative icon construction (`createServiceIcons()`) and client logo loading fallbacks (`createClientLogo()`).
+  - **SSE Connection Lifecycle & Payload Contracts (`dashboard.test.js`)**: Added stream tests checking Server-Sent Event heartbeat emission, payload schema schemas, and client close event listeners (`req.on('close')`) to verify callback cleanup and prevent connection-based memory leaks.
+
+## [1.7.29] - 2026-05-27
+
+### Fixed
+
+- **Missing Radarr/Sonarr Links on Active Downloads (Issue #59)** — Resolved a bug where Radarr and Sonarr deep-link buttons were missing from active/completed download cards on the main dashboard for administrator users. Implemented a generic link enrichment utility `decorateDownloadsWithArrLinks()` to query Radarr and Sonarr catalog APIs in parallel and match downloads via their database ID or title, circumventing minimal metadata in cached records that lacked `titleSlug`. Added a robust integration test to safeguard links decoration for dashboard downloads.
+
+## [1.7.28] - 2026-05-27
+
+### Fixed
+
+- **Missing Sonarr Link on TV Requests (Issue #58)** — Resolved a bug where the Sonarr deep-link button was missing on TV request cards while Radarr links correctly appeared on movie request cards. Added support for all camelCase TVDB ID variants (`tvDbId`, `tvdbId`, `theTvdbId`, `theTvDbId`, `TvDbId`, `TheTvDbId`) on both backend link decoration (`server/utils/ombiHelpers.js`) and frontend rendering (`client/src/ui/requests.js`). Added a dedicated integration test to safeguard links decoration for TV requests.
+
+## [1.7.27] - 2026-05-27
+
+### Fixed
+
+- **Frontend Dashboard Serve Regression (Issue #57)** — Resolved a critical regression where the Vite-built frontend dashboard UI was not served. Consolidated Express configurations by migrating static files serving and SPA routing into the `createApp` factory in `server/app.js`. Cleaned up `server/index.js` to import and instantiate the app from the factory, successfully eliminating over 300 lines of duplicate route and middleware registrations, and ensuring alignment between development testing and production runtime configurations.
+
+## [1.7.26] - 2026-05-27
+
+### Fixed
+
+- **Missing Ombi & \*Arr Request Links (Issue #56)** — Resolved an issue where the Ombi and \*Arr lookup buttons failed to appear against request cards. Added `decorateRequestsWithArrLinks` to aggregate IDs and query Radarr/Sonarr libraries during SSE stream decoration and backend REST fetching. Also fixed a frontend condition failing to generate Ombi links for TV requests by checking a broader set of ID properties (`theTvDbId`, `theTmdbId`, `imdbId`).
+
+## [1.7.25] - 2026-05-27
+
+### Fixed
+
+- **Ombi TV Request Status, User, and Date Resolution (Issue #53)** — Resolved the root cause where Ombi TV show requests consistently displayed "unknown" status, "unknown" user, and missing request dates. The Ombi API nests all TV request data (`requestedUser`, `approved`, `available`, `denied`, `requested`, `requestedDate`) inside `childRequests[]` sub-objects, while the application previously only inspected top-level properties.
+  - `OmbiRetriever._hydrateRequest()` now hydrates `requestedUser` on each `childRequests` entry and promotes `requestedDate` from `childRequests[0]` to the top level.
+  - `getRequestStatus()` (server and client) now aggregates status flags from `childRequests[]` when top-level properties are absent.
+  - Client-side date display now falls back to `childRequests[0].requestedDate` as a defensive measure.
+
+## [1.7.24] - 2026-05-27
+
+### Enhanced
+
+- **Gitea Actions Prioritization** — Optimized CI/CD workflow pipeline executions to prioritize critical `build-image` Docker compilation runs. Redundant security audits, tests, coverage generation, and RAML packages are now bypassed on `release/**` branches (which have already passed validation during development on `develop`).
+- **Workflow Concurrency Controls** — Configured active concurrency groups with `cancel-in-progress: true` inside both `ci.yml` and `build-image.yml` pipelines, ensuring obsolete running jobs are aborted instantly when newer commits are pushed.
+
+## [1.7.23] - 2026-05-27
+
+### Enhanced
+
+- **Request Card Link Alignment (Issue #55)** — Aligned deep links on request cards (Ombi link and administrator Sonarr/Radarr deep links) with the elegant, inline `.service-icon` styling used across the downloads and history dashboard cards. Replaced bulky button elements with clean hoverable icons in a shared `.service-icons-container`, maintaining strict administrator-only visibility for *arr links.
+
+## [1.7.22] - 2026-05-27
+
+### Fixed
+
+- **Theme Switcher Multi-Button Support (Issue #54)** — Resolved a frontend bug where themes other than Light failed to apply because the Javascript code queried a non-existent `#theme-toggle` element. Re-engineered the switcher to query all `.theme-btn` selectors inside `.theme-switcher`, managing and toggling the active class styling across `light`, `dark`, and `mono` themes, and cleanly persisting choices to local storage.
+- **Ombi TV Requester User Extraction Fallback (Issue #53)** — Resolved a bug where TV show requests from Ombi displayed as "unknown" user because requester attributes were nested under non-standard properties (`user`, `requestedBy`, `ombiUser`, `requestedByUser`, and nested seasons/child requests arrays). Added robust multi-layer extraction logic on both backend and frontend layers to resolve requester usernames under all TV request structures.
+- **Configurable Webhook Commit Delay & Retry Loop (Issue #53)** — Mitigated race conditions between Ombi webhook events and database commits by introducing a configurable `OMBI_WEBHOOK_REFRESH_DELAY_MS` delay (defaulting to `2000`) and a smart 3-attempt retry polling loop to verify updated requester data before cache updates.
+
+### Added
+
+- **Admin Request Card *arr Library Lookup (Issue #53)** — Added library deep-link lookup for admin views. Request cards now query Sonarr and Radarr library caches and dynamically render deep-link navigation icons in the card actions container if the item exists.
+- **Request Date/Time Presentation** — Added request date and time display inside request cards formatted as `YYYY-MM-DD HH:MM`.
+- **Unknown (Ombi) Dotted Underline Tooltip** — Added user-friendly placeholder "Unknown (Ombi)" with dotted underline and explanatory hover tooltip when user details are unavailable from the Ombi database.
+- **Expanded Test Coverage** — Introduced two new frontend DOM test suites (`tests/frontend/ui/theme.test.js` and `tests/frontend/ui/requests.test.js`) and robust backend unit test assertions in `tests/unit/ombiHelpers.test.js`.
