Added logging of Media Library scanning errors – “show errors” button in Media Library Preferences.
Added Advanced Preferences option for flushing playback queue on manual track change (default: on).
Made “Open containing folder” command work with tracks in archives – opens folder containing the archive.
Added an option to preserve last-modified timestamps of tracks when updating tags.
Additional safeguards against corrupted configuration in case of a system crash while saving (FlushFileBuffers).
File Operations: delete/recycle prompt always says “Delete” rather than “Recycle”, since not every volume supports recycle action.
FFmpeg 3.4.6, now compiled with MS compiler, binary size reduced due to DLL runtime.
Implemented reading of cue+bin audio CD images.

Made possible to check for updates of components listed but not hosted on foobar2000.org.
