NEW:
  (Playback) Better caching of codec testing to improve
   start time of playback sessions.
  (Preferences) Split transcoder slots into CPU and GPU slots.

 FIXES:
  (Ad Detection) Logs were left next to the target media file
   instead of in the Plex Log folder.
  (CreditDetection) Credit detection would fail on windows
   servers.
  (Docker) Various issues related to permissions could occur
   when explicitly setting UID and GID.
  (Downloads) Any existing files in ‘Downloads temporary
   directory’ would be deleted.
  (Downloads) Setting ‘Maximum simultaneous background video
   transcode’ to ‘Unlimited’ would prevent any download
   transcodes or optimizations from running.
  (Music) Similar artist tags were not being loaded.
  (Optimizations) HEVC Optimization could result in a file with
   no video.
  (Subtitles) When automatically selecting subtitles forced
   subtitles were preferred over full subtitles.
  (Transcoder) SW fallback would fail when CPU slots were set
   to Unlimited.
