3. Bugfixes

The following user-visible bugs were fixed:

• Will no longer lose focus on Raspberry Pi when launched fullscreen in an Xorg session [PR#995].
• Release builds now use dosbox-staging.conf as the primary conf file instead of dosbox-staging-git.conf [PR#932].
• Windows release builds once again mount Opus CD-DA tracks, which was a regression in 0.76 [PR#885].
• AUTOTYPE now works with all games. Until now, a subset of games didn't respond to its keystrokes [PR#942].
• Shoulder triggers on some six-axis controllers, such as the PS4 and Logitech's F310 and F710 controllers, can now be mapped [PR#944].
• When toggling out of fullscreen mode, in some corner cases this resulted in a blank window. This is now fixed [PR#1096].
