Error messages named the resolved language for a user who only ever defaulted to orig. Audio tracks now carry is_original, resolved through Tracks.by_language so it agrees with the downloader.
Detect the dot/space style from the full folder template instead of per segment, so `{artist}/{album} ({year})` no longer yields `Some.Artist/Some Album (2025)`. Also drops empty `[]` groups like the existing `()` handling and removes redundant cleanup passes.
Only fall back to Title.language when the manifest labels nothing, and reject und as firmly as a missing tag. Exported direct-URL subtitles now replace the re-parsed set, and fetch failures stay distinct from parse failures.
One CPython interpreter caps sustained segment throughput at ~160 MB/s;
spawned children each run the existing thread-pool path on a contiguous
chunk of the batch, reaching NIC line rate on fast CDNs. Opt-in via
--download-processes (default 1), engaged only for 24+ segment batches.
Sessions are rebuilt per child from a picklable spec; RnetSession falls
back to a single process when it has no impersonate preset.
Merge cues at the string level instead of round-tripping through
pycaption, which dropped inline tags and cue settings. STYLE and
REGION blocks are kept, duplicate boundary cues splice correctly,
and a bad timing line now skips the cue instead of crashing.
Also rank pysubs2 above SubtitleEdit for ASS to TTML/VTT since
SubtitleEdit flattens inline styling there. Documented the measured
backend fidelity table and added regression tests for the merge.
Upstream migrated the free IMDxAPI from imdbapi.dev to api.tiffara.com.
Endpoints and JSON schema are unchanged, so only BASE_URL and the
user-facing docs/docstrings needed updating.
Share one best-audio selector across the episode and music paths so best/all works for songs, descriptive audio is capped to one track, and codec_priority is honored. Guard --channels and 16:9 canvas math against tracks missing channel/width metadata. Extend --best-available to video languages and full resolution misses in both normal and hybrid mode, and count only deliverable ranges when reporting missing resolutions. Rank video by resolution before bitrate, and trim group audio selections to one track per song with a warning.
BREAKING CHANGE: a missing resolution with -r HYBRID now errors without --best-available, matching non-hybrid behavior.
Swap cookie/PKCE auth for the OAuth 2.0 device authorization grant with a cached rotating refresh token. Fix the connection-token key (`cat`) and move the cache to {cache}/vpn/ to match ProtonVPN.
BREAKING CHANGE: cookie-file auth removed; run once with `enable: true` to approve a device code.
Optional ranking of forced/normal/sdh per language, mirroring audio.codec_priority; first track gets the default flag, so this also picks the default subtitle. Unset = existing behavior.
Persistent job history (capped by serve.history_limit, stored under cache), profiles/config reads, maintenance + env-check endpoints, and 409 conflict code.
Optional Episode.air_date names daily/sports content by date instead of SxxExx (no template change). Presentation-only; `{year}` dropped only when it duplicates the date's year. Round-trips via export/import.
Allow directories.services entries to be git repo specs (URL/owner-repo/ @branch) alongside local paths: clone + TTL-pull as cache, list-order priority with a duplicate-ignored summary, a refresh-services command that force-syncs and reports the per-service diff, and a dirty-clone guard that protects local edits on the automated path. Adds binaries.Git and a redact_paths config toggle.
cdm lookups used the raw service key while decryption upper-cases its keys, so a case-mismatched cdm entry silently used the default. Add a shared ci_get helper, route cdm/decryption through resolvers, drop a redundant decryption mutation and dead downloader writes, and add a regression bench.
Group selected videos by (resolution, range, codec) and mux each group into one MKV; only language is collapsed, so ranges/codecs/resolutions stay in separate files. Adds --merge-video flag + muxing.merge_video config (global and per-service), docs, and tests.
unshackle's DASH parser only recognised Widevine and PlayReady ContentProtection, so services using W3C EME ClearKey had to fake a Widevine object and monkey-patch get_content_keys. Add a first-class ClearKeyCENC DRM type so services just implement a license callback.
- ClearKeyCENC (core/drm/clearkey_cenc.py): KID-based, no CDM/PSSH; builds the W3C JSON license request (unpadded base64url), parses the JWK Set response (dict/str/bytes), falls back to POSTing the manifest Laurl when the service returns None, decrypts via the same shaka/ mp4decrypt CENC path as Widevine
- DASH.get_drm emits ClearKeyCENC for scheme e2719d58-...; KID from own or sibling mp4protection cenc:default_KID, Laurl across dashif/legacy/ bare namespaces
- track.download dispatches prepare_drm for ClearKeyCENC; dl.prepare_drm gains a clearkey branch (cache/vault lookup, license-failure tolerated when content_keys pre-populated, vault push, export)
- Service.get_clearkey_license base callback (default None -> Laurl); drm_from_dict reconstructs ClearKeyCENC for export/import round-trip
- EXAMPLE service + config demo the callback
- Tests: tests/core/test_clearkey_cenc.py and an export round-trip case
- Docs: DRM_CONFIG.md ClearKey section
Instrument the full download pipeline in the structured JSONL debug logger and make adding logging to new features a one-liner.
Coverage:
- DRM license request/response, content keys (incl. remote-CDM seam) and decrypt timing across Widevine/PlayReady/ClearKey
- DASH/HLS/ISM manifest fetch + parse milestones (HLS.to_tracks also covers the m3u8_parser path used by iTunes/ATV-style services)
- Per-backend vault get/add via the Vaults manager, track selection, subtitle conversion, repackage, normalize_vui, and full mkvmerge mux (command, duration, output size, warnings)
- All external tooling (ffmpeg, ffprobe, mkvmerge, mkvpropedit, dovi_tool, SubtitleEdit, ccextractor) via a unified `tool_run` op, centralised in run_step/ffprobe + log_tool_run
DX:
- Add log_event() / timed_operation() primitives (no-op when disabled); retrofit ~91 guard/timing blocks onto them
- Fix message= collision in log_drm_operation/log_vault_query/log_service_call that raised TypeError on the live decrypt path
Redaction (redact_all = redact_text -> redact_url -> redact_path):
- Collapse content/CDN/api URLs to `redacted[.ext]`
- Strip local path prefixes (install root -> <unshackle>, venv -> <venv>, home -> ~)
- Apply to every logged string so shared logs leak no URLs, paths or usernames
- Drop per-request service_call logging (manifest parse is the request seam)
services.<TAG>.dl values only applied when the key was also set in the global dl: section (equality check against config.dl missed Click's declared defaults). Gate on Click's ParameterSource instead: CLI/env > service dl > global dl > defaults, converted via each option's own type.
- record parameter sources on serve's hand-built context so client values are never clobbered
- accept range/list as natural keys for range_/list_
- harden QualityList (YAML int) and SlowDelayRange (YAML bool) converts
Replace the hardcoded conversion if/elif in Subtitle.convert with a capability-matrix backend registry (subtitle_convert.py): each backend declares the source->target pairs it supports plus a rank, and run_conversion tries them in order as a real fallback chain. conversion_method pins a backend but still falls back (pin-then-fallback).
- Detect the cross-platform SubtitleEdit 5+ CLI (seconv) and use its --flag syntax for convert, SDH stripping, and reverse-RTL
- Protect styled ASS/SSA from automatic SRT downconversion; honor an explicit --sub-format / sidecar_format
- Read segmented fVTT (wvtt) and fTTML (stpp) directly from fragmented MP4
- Improve ASS/SSA font detection: inline \fn overrides, Format-located Fontname column, @-prefix strip, case-insensitive de-dup; covers SSA too
- Update SUBTITLE_CONFIG.md, example yaml, README; add regression tests and a backend benchmark script
Add services.<TAG>.title_map exact-match dict to rewrite service-provided titles before naming/output. Shared remap_titles helper applied on local dl, import, and client-side dl --remote (server stays raw so clients can override names for services they don't have installed locally).
Add --real-video-bitrate/-rvb and --real-audio-bitrate/-rab to measure a track's true bitrate from actual media size instead of the manifest's declared value, which is often inflated. Useful for accurate track listings and --vbitrate/--vbitrate-range selection.
Single-file tracks are measured exactly; segmented HLS/DASH/ISM are sampled. Only the top renditions per quality tier are probed, in parallel, so it stays fast. Without the flags, behaviour is unchanged.
Adds optional `audio.codec_priority` list in unshackle.yaml to define preferred audio codec order when tracks share the same bitrate and language. Listed codecs rank in the order given; unlisted codecs retain bitrate-based order and fall after the listed group (soft priority - nothing dropped). Atmos and descriptive rules still apply last.
- Wire --no-proxy-download through download_manager + handlers + swagger
- Add tag/proxy/tmdb_id/animeapi_id/enrich/worst to DEFAULT_DOWNLOAD_PARAMS
- Normalize `slow` (bool/"MIN-MAX" string/list) to tuple before invoking dl.result
- Overlay any /api/download flag declared under `serve:` in unshackle.yaml as a default (downloads, workers, best_available, etc.); request body still wins
- Quiet successful worker stderr from `warning` to `debug` (kept under job.worker_stderr for ?full=true)
- Include HYBRID in range validator
- Document new flags + overlay layering + max_concurrent_downloads / download_job_retention_hours
Replace get_ip_info + get_cached_ip_info pair with a single unshackle.core.utils.ip_info module providing a normalized return shape across providers. Adds optional ipinfo_api_key config for the ipinfo.io Lite endpoint (higher rate limits, ASN/org/continent data), swaps the ipapi.co fallback for ip-api.in, and migrates all callers (service, gluetun, remote_service, api/handlers, DSNP, YT) to the new import path. Auth token is sent per-request and never attached to the shared session headers.
Update API docs, Swagger schema, handlers, and example config to reflect --export as a boolean flag that auto-generates export files in the configurable exports directory.
