/api/health needs X-Secret-Key but stays outside the rate limit. Only the admin key gets load_errors from /api/services, default error details no longer name the exception class, and a prepare signal replaces aiohttp's Server banner on every response while the CDM routes keep their own.
A dual widevine/playready cdm entry now loads the device of the client's DRM system, for old clients too since they already send cdm_type. A new client hands a capped track to its own device for the track's DRM system, and raises the refusal only after its local vaults miss.
Drop null keys from every licence, server and export source, not only Widevine. dl now finds remote sessions and imports through ServerKeySource instead of private fields.
A manifest snapshot module now saves and restores DASH/ISM parser state for --remote and export/import, so an import keeps the service's period filter without fetching the manifest.
cast_dl_params feeds ctx.params to dl() and dl.result() as on the CLI. A string lang value now returns 400 instead of splitting into letters, and -r accepts HDR10+.
Session update events carry the new action as action_entry instead of the full log; access lines stay out of the log ring unless --debug. Job events build and redact their dict once, the progress interval matches the 0.5 s poll, and dashboard stats are serialized once.
The tool writes to a temporary file through run_step, which gains a timeout that hides the command line. A missing tool now raises instead of skipping.
A bad value now gets 400 INVALID_PARAMETERS at submit and the worker casts each option; a flat dl key such as quality or lang no longer fills a service option of the same name.
A service option named like a dl option (e.g. --profile) is no longer dropped or mixed with the dl value; the server casts nested values and keeps cli defaults nested.
server_cdm: true on a remote_services entry now licenses remote runs with the server CDM even when the service has its own cdm entry, which stays the local-run device and the fallback. A services.<TAG>.server_cdm replaces the server value for one service, per-service entries match the tag in any case, and the configured fallback logs at info.
BREAKING CHANGE: with server_cdm: true, a per-service cdm entry no longer makes your own device license remote sessions; use dl --cdm or services.<TAG>.server_cdm: false.
get_tracks_for_variants skips a later manifest's track when a held track has the same signature, so a track whose ID changes per manifest is listed once.
Fix DASH SegmentTimeline negative @r and Pattern, TTML sidecar sets with no contentType, HLS CHANNELS identifiers and Dolby channel masks; test against 408 public DASH/HLS/ISM manifests.
Set muxing.track_names to native to name an unnamed track in its own language (中文（繁體）, Português (Portugal)) in place of English. The same script and region rules apply. --list, the muxed names and the REST API track_name follow the option. A test fixture resets the muxing options, so a local unshackle.yaml cannot change test results.
Unnamed tracks get the English language name (default region left out); subtitle tags gain the script their region implies (zh-TW -> zh-Hant-TW). Refs #169
Judge a vault KID only on a file whose KID map holds it, tell remote vaults of a bad pair only once another key replaces it, and let the server CDM unflag a pair it returns; the server never flags a CDM-licensed pair. Log FFmpeg stderr on a failed check and name the missing CDM when none is set.
The client set server cookies with no domain and sent all of them to every host, so a CDN refused segment requests with 400 header too large. rnet sessions now send cookies too.
POST/DELETE /api/dashboard/drain refuses new sessions and jobs (SERVER_DRAINING, 409) and warns open sessions. A CDN can replace a 5xx body, so server errors are now 422, retryable ones and the tunnel check 424, and a new middleware turns any 5xx into 422.
BREAKING CHANGE: INTERNAL_ERROR, DOWNLOAD_ERROR, WORKER_ERROR and the fallback return 422 instead of 500; NETWORK_ERROR and SERVICE_UNAVAILABLE return 424 instead of 503; /api/tunnel/check failures return 424 instead of 502.
A reverse tunnel over the remote connection: the server's service traffic leaves through the client's own network. Only the client dials. Adds the tunnel-test command.
Every structured error carries a short ref, appended to its message and logged with the request; /api/dashboard/status gains per-service error counts. Gzip now compresses in place.
Cloudflare replaces an origin 502 body with its own page, so clients got "502: Bad gateway" in place of the error and resent each failed licence.
BREAKING CHANGE: SERVICE_ERROR and DRM_ERROR now return HTTP 422 instead of 502.
The server and the client both check a forwarded cache file before they write it, because Cacher decodes it with jsonpickle. The session-create cache write now runs off the event loop.
Click picks the subcommand before the dl callback applies the service config, so Services.resolve_command now applies remote and server first. A REST API job routes from its request only.
Relabel HEVC HDR10 tracks whose first fragment carries ST 2094-40 SEI as HDR10P, for dl, the REST API and remote sessions. Config key hdr10plus_probe (default true).
Builds per-scene L1 in unshackle (PQ mean, letterbox-aware) with a generate_dv_mode config (v29/v40/legacy); a failed hybrid no longer exits 0 with no video.
--proxy now overrides HTTP(S)_PROXY and the Windows system proxy while keeping the env CA bundle. Core fallback sessions use the run's proxy, and a warn-only audit hook names service code that sends a request or opens a raw socket outside the proxy; a session with proxy_exempt = True opts out.
A tag with a region (en-US, es-419) matches only that variant and reports a miss instead of taking another region. A bare tag takes the variant it means (pt -> pt-BR, es -> es-ES) and falls back to any variant only when that one is missing. `orig` prefers the title's own tag, `-sl orig` resolves, forced and SDH subtitles are picked from their own pools, and the track name no longer strips the region from the cached language.
BREAKING CHANGE: -l es-419 no longer selects es-ES, and language_priority, language_tags and muxing.default_language treat a regional tag as exact.
