+## [0.9.15] - 2026-05-27
+
+
+### Added
+
+- **sentry**: enhance error handling by skipping user input errors in CaptureError
+
+### Changed
+
+- **ci**: point Forgejo URLs at torrentclaw org (post-transfer)
+- **sentry**: decouple agent import via string-match, rename predicate
+
+### Documentation
+
+- **positioning**: reframe unarr around download/stream/transcode, drop misleading search-first wording
+
+### Fixed
+
+- **ci**: unset GITHUB_TOKEN so goreleaser uses GITEA_TOKEN
+- **sentry**: skip "daemon not running" stop/reload errors
+
+### Other
+
+- **scripts**: harden release.sh against double-release and inline version bumps
+- untrack .claude/ (private local config)
+## [0.9.14] - 2026-05-27
+
+
+### Added
+
+- **vaapi**: hybrid CPU-scale + hwupload encode path (QW2, 0.9.14)
+
+### CI/CD
+
+- port workflows from .github/ to .forgejo/ (Forgejo Actions)
+
+### Fixed
+
+- **daemon**: defensive IsClosed check in watchSessionReady poll loop
+- **daemon**: use parent ctx for MarkSessionReady so cancel propagates
+- **release**: move gitea_urls to top-level (goreleaser v2 schema)
+## [0.9.13] - 2026-05-27
+
+
+### Added
+
+- **agent**: session-ready webhook for SSE-driven player handshake (0.9.13)
+- **agent**: send full transcoder diagnostic in register payload (0.9.12)
+
+### Fixed
+
+- **daemon**: defer probeCancel so a panic mid-diagnostic still releases ctx
+
+### Other
+

## [0.9.6] - 2026-05-26
+
### Added
-- **auto-upgrade**: when the web flags the agent for upgrade
- (`POST /api/internal/agent/upgrade` or the "Force update now" button),
- the daemon now downloads and replaces the binary in-place, then exits so
- the service supervisor (`systemd Restart=always` on Linux, the equivalent
- on macOS/Windows) respawns on the new version. No `unarr update` step
- required from the user. Still opt-in — only fires when the server sends
- the upgrade signal.
-
-### Changed
-
-- The `OnUpgrade` daemon callback no longer just logs `run unarr self-update`;
- it now triggers the actual upgrade in a background goroutine.
-
+- **daemon**: auto-apply upgrades when server signals (0.9.6)
## [0.9.5] - 2026-05-26
+
### Added
-- **funnel**: optional CloudFlare Quick Tunnel subprocess. `unarr funnel on`
- spawns `cloudflared` as a child process and registers an anonymous
- `https://.trycloudflare.com` hostname tunnelled to the daemon's
- HLS server. The hostname is reported back to the web on every sync so the
- in-browser player picks it up automatically — cross-network playback now
- works on torrentclaw.com without Tailscale or port forwarding. Bytes
- proxy through CloudFlare; TorrentClaw still doesn't relay content.
-- **funnel**: on by default for fresh installs (NAS/Docker get cross-network
- HTTPS automatically); existing configs that pre-date the feature stay
- off until the operator runs `unarr funnel on`.
-- **funnel**: auto-downloads cloudflared to the unarr data dir when not on
- PATH (Linux amd64/arm64/armhf/386). ELF magic + size sanity check on the
- download; `O_EXCL` partial-write so concurrent daemons don't clobber
- each other.
-- **funnel**: subprocess supervisor keeps the tunnel up across cloudflared
- crashes + CF's ~6h Quick Tunnel rotation. Exponential backoff (2 s → 5 min)
- on persistent failures. The web's reported URL is cleared the moment
- cloudflared exits so an outdated hostname doesn't keep handing out 502s.
-- **funnel**: `unarr funnel status` shows the live URL once registered.
- See README §`[downloads.funnel]` for the throughput / latency caveats of
- CF's free Quick Tunnels.
-- **docker**: the official `torrentclaw/unarr` image now bundles
- `cloudflared` so the funnel works the moment the container starts — no
- first-run download.
-
-### Fixed
-
-- **hls/libx264**: bump the H.264 level we hint to libx264 by one tier so
- anamorphic (>16:9) sources stop emitting unplayable streams. 720p at
- level 3.1 silently rejected 1728×720 cinemascope frames with
- `frame MB size > level limit`; 720p now ships at level 4.0, 1080p at 4.1.
- Decoder compatibility is unaffected — every device that handles 1080p
- already handles ≥ 4.1.
-
+- **funnel**: cloudflare quick tunnel embedded subprocess (0.9.5)
## [0.9.4] - 2026-05-26
-### Removed
-
-- **streaming**: retire the custom WebRTC DataChannel pipeline. The daemon no
- longer ships pion/webrtc, the WSS signaling client, or the wire framing
- package — every in-browser session now uses HLS over HTTP from the daemon
- (Tailscale / LAN / UPnP). Browser P2P (WebTorrent) bytes never re-enabled.
-- **config**: `[downloads.webrtc]` block removed from the TOML schema; existing
- config files with the section parse cleanly because go-toml ignores unknown
- sections.
-- **seed_file**: `mode=seed_file` task handler + `engine.SeedFile` helper
- dropped — the last in-browser caller was retired with the WebRTC player.
-- **wstracker-probe**: standalone probe binary removed.
-
-### Changed
-
-- **agent wire**: `SyncResponse.WebRTCSessions` (JSON: `webrtcSessions`) renamed
- to `StreamSessions` (JSON: `streamSessions`). The Go type `agent.WebRTCSession`
- is now `agent.StreamSession`. Wire-incompatible with web < 2026-05-26.
-- **torrent**: `buildMagnet` no longer accepts an `extraTrackers` variadic —
- the default tracker list is the only set used.
-
-### Fixed
-
-- **hls**: clamp the ffmpeg `-b:v` to the bitrate cap derived from the EFFECTIVE
- output height instead of the requested quality. Previously asking for "2160p"
- on a 1080p source overshot the H.264 level we resolved from the effective
- height (4.0, max 20 Mbps) and made libx264 abort with
- `VBV bitrate > level limit`.
-
-## [0.9.2] - 2026-05-21
### Added
-- **vpn**: `unarr vpn` command (`status`, `enable`, `disable`) to manage the managed
- WireGuard split-tunnel, with `vpn status --check` to verify provisioning.
-- **vpn**: report split-tunnel state (active, exit server) to the web on register
- + every sync, so the dashboard shows which agent holds the single WireGuard slot.
-- **vpn**: send the agent id when fetching the VPN config so the web can arbitrate
- the single WireGuard slot — the first agent claims it; the rest are told to run
- OpenVPN on their own host (1 agent on WireGuard + up to 9 on OpenVPN).
+- **stream**: retire WebRTC, HLS-only, bump 0.9.4 (**BREAKING**)

`unarr doctor` checks: config file, API key, server connectivity (with latency), agent registration, download directory, disk space, and version.
+### Updating unarr
+
+unarr supports three update paths. Pick whichever fits your workflow.
+
+**1. Manual self-update (always available).**
+
+```bash
+unarr self-update # interactive update to latest
+unarr self-update --force # reinstall same version
+unarr self-update --allow-unsigned # accept releases without checksum signature
+```
+
+The CLI downloads the new release archive over HTTPS (from
+`torrentclaw.com/releases/download/v/`), verifies SHA-256, swaps the
+binary in place (`.backup` kept next to it), and restarts the systemd
+user unit if the daemon is running.
+
+**2. Auto-apply on server signal (default, since 0.9.6).**
+
+When you press **"Force update now"** on the web (Settings → Agent → Force
+update), the server sets a flag your daemon polls every sync (~3 s). On
+the next sync the daemon downloads the new binary, replaces itself, and
+exits — `systemd Restart=always` respawns on the new version. No SSH, no
+terminal access required. Works headless on NAS / Docker.
+
+The button shows an amber warning if your agent is below 0.9.6 (older
+daemons see the signal but only log "run unarr update" — the operator
+must run the command manually that one time).
+
+**Opt out of auto-apply.** Some users prefer reviewing CHANGELOG before
+applying. Disable in `config.toml`:
+
+```toml
+[daemon]
+auto_upgrade = false
+```
+
+With `auto_upgrade = false`, pressing the web button still flags your
+agent (so the daemon logs the new version on next sync), but the daemon
+will not download / replace anything — you run `unarr self-update` when
+you're ready.
+
+**3. Docker auto-restart with a new tag.**
+
+```bash
+docker pull torrentclaw/unarr:latest
+docker compose up -d
+```
+
+Tags published: `latest`, `0.9`, `0.9.7`, ... — pin to a minor (`0.9`)
+for opt-in patch updates without surprises.

+| `enabled` | bool | `true` | Persists finished HLS encodes per `(source, quality, audio_index)`. A second play of the same file at the same quality reuses the segments — no ffmpeg, near-zero CPU, instant playback. Set to `false` to delete segments on session close (original behavior). |
+| `size_gb` | int | `5` | Cache budget in gigabytes. When exceeded the LRU sweeper evicts the least-recently-used cached encodes hourly. Minimum 1 GB (smaller values are clamped up). |
+| `dir` | string | `""` | Custom storage path. Empty defaults to `~/.cache/unarr/hls-cache` (Linux/macOS) or the user cache dir (Windows). |
+
+**What it does.** First play encodes normally (ffmpeg writes segments).
+On session close, if every segment is on disk and ffmpeg exited cleanly,
+the directory is sealed with a `.complete` marker and kept. Next time the
+same source + quality combo is requested, the daemon serves segments
+straight from disk — no transcode, no warm-up, no CPU cost.
+
+**Why per (source, quality, audio).** Renaming the file or switching
+quality invalidates the entry: the segments are tied to the exact source
+bytes and the exact ffmpeg parameters. Re-encoding generates a new key.
+
+**Eviction.** A background goroutine wakes every hour. If total cache size
+exceeds `size_gb`, it deletes the oldest entries (by mtime) until under
+budget. Active sessions are pinned — they never get evicted mid-play.
+
+**Disable.** Either edit the TOML to set `enabled = false`, or remove the
+cache directory manually (it'll be recreated as needed). Disabling does
+not delete existing cached segments — drop `dir` (or `~/.cache/unarr/hls-cache`)
+to reclaim the space.
