• Live streaming:
  • Fix playback issue for HLS live streams without program date time information (#8560).
  • Fix playback issue for multi-period DASH live streams (#8537).
  • Fix playback failures when playing live streams with video tunneling enabled (#8570).
• IMA extension:
  • Fix handling of repeated ad loads, to avoid ads being discarded if the user seeks away and then back to a preloaded postroll (for example).
  • Fix a bug where an assertion would fail if the player started to buffer an ad media period before the ad URI was known then an ad state update arrived that didn't set the ad URI.
  • Add ImaAdsLoader.focusSkipButton to allow apps to request that the skip button should receive UI focus, if shown (#8565).
• DRM:
  • Re-use the previous DrmSessionManager instance when playing a playlist (if possible) (#8523).
  • Propagate DRM configuration when creating media sources for ad content (#8568).
  • Only release 'keepalive' references to DrmSession in DefaultDrmSessionManager#release() if keepalive is enabled (#8576).
