4.3.3

- Fixed the issue of being unable to insert or change optical discs, floppy drives, and memory cards when filenames contained spaces.
- Added equalizer.
- Bubbles on the built-in VNC screen will automatically fade when there is no interaction.
- The default setting for automatically switching to external mouse mode on the built-in VNC screen is now off.
