New in this version

• MPEG-DASH support. Streams described by an .mpd manifest are now detected
  and downloaded, with the available qualities read from the manifest.
• AES-128 encrypted HLS is decrypted during download, using the key declared
  in the playlist.
• Fragmented MP4 (CMAF) streams are supported, including initialization
  segments and byte range playlists.
• Subtitle tracks are detected and saved as WebVTT files, one per language.
• A failed segment is retried three times before a download gives up, and any
  running download can be stopped from the same button that started it.
• The whole row acts as a progress bar and shows the live segment count.
• A new Clear button empties the panel for the current tab, which matters on
  sites that never reload the page.
• Advertising is kept out of the list, and the popup reports how many items
  were hidden.
• Every switch on the settings page now does something. The ones that did
  nothing have been wired up or removed.

Fixed

• Files saved from a stream opened as an empty movie in VLC and QuickTime and
  showed a duration of 13 or 24 hours. They are now written as a progressive
  MP4 with real sample tables and the correct duration.
• Playlists that address segments by byte range produced a file repeating the
  same clip dozens of times.
• Many streams failed silently because segment requests carried no Referer.
  They now keep the context of the page they came from.
• Segments from different qualities on the same site could be mixed into one
  unplayable file.
• A stream with a separate audio track produced a corrupt video. The audio is
  now saved as its own file beside it.
• Standalone .m4a and .m4v files were never listed.
• Downloads started from a private window were recorded in the normal download
  history and sent normal session cookies. They now stay in the private session.
• An incomplete download was saved anyway. It now stops with a clear message
  instead of writing a broken file.
• Peak memory use during a download has been cut by more than half.
