NESd changelog:
Changed
NESd can now handle the audio output disappearing (e.g. headphones unplugged)
Replaced the unmaintained third-party audio backend with a custom audio plugin
Error notifications no longer show raw stack traces
Notifications are now deduplicated and capped, so a repeating error no longer floods the screen
A failed settings save now shows a warning instead of silently reverting the changes on the next launch
Fixed
Fixed rewind crashing on Windows: the LZ4 compression library was missing from the Windows builds since 0.14.0
