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.
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.
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.
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 service that sets the flag gets no cookie load, no authenticate() call and no cookie save on a search, on the CLI and in the REST search handler. /api/services reports it as anonymous_search.
A REST job shows a wait_for_approval message as its notice field. search, list-titles and list-tracks fail at once on a login that needs the user. A remote client downloads through the --proxy it sends.
Regions in GEOBLOCK refuse the service and everything else is allowed. A hit stops the run with a region error instead of auto-proxying; the check also covers proxy exits and the remote-dl client region.
Route titles with a dtsx/dtsy sample entry to MP4 via MP4Box, since Matroska has no CodecID for DTS-UHD. Add per-rendition HLS audio codec selection, fix merge_segments progress and its cleanup path.
Init segments now carry dvcC/dvvC with a profile-keyed sample entry and the dby1 brand; track ids cover the manifest URL so per-range ladders stop colliding, and the remote path carries the Atmos flag without inventing a JOC count.
Uppercase entries in ALIASES never resolved, because get_tag lowercased the input but not the alias. Match real tags first so a service's own tag cannot be taken by another service's alias.
Delete the dead grouped-download block, the planner, and the music service hooks; Song now flows through the one download loop, gets tagged via tag_file, and answers -w with {disc}x{track} keys.
BREAKING CHANGE: GROUP_AUDIO_DOWNLOADS, get_music_track_options and get_music_collection_label are gone. A music service returns one Audio track per quality and lets the framework choose.
