Stella release 6.3 for Linux, macOS and Windows is now available.

• Added adjustable autofire.
• Added 'Dark' UI theme.
• Extended global hotkeys for debug options.
• Added option to playback a game using the Time Machine.
• Allow taking snapshots from within the Time Machine dialog.
• Added the ability to access most files that Stella uses from within a ZIP file. This includes the following:
  • Per-ROM properties file (so one can distribute a ROM and its associated properties).
  • Debugger symbol (.sym) and list (.lst) files, etc.
  • Several others, as we extend the support.
  Basically, you are now able to put many files that Stella uses inside one ZIP file, and distribute just that file.
• Extended AtariVox support to handle flow control, so that long phrases are no longer corrupted/cut off. This includes properly supporting the 2600-daptor II, which is flashable to an AVox-USB converter.
• Added auto-detection of the serial port used for an AtariVox-USB adaptor.
• Added QuadTari controller support.
• Added option to select the audio device.
• Added support for CDFJ+ bankswitching type.
• Further enhanced UA bankswitching to support more Brazilian carts.
• Added option to display detected settings info when a ROM is loaded.
• Added another oddball TIA glitch option for delayed background color.
• Added option to disable aspect ratio correct scaling.
• Added debugger pseudo-registers '_timwrapread' and '_timwrapwrite', which are set when the RIOT timer is read/written on timer wraparound, respectively.
• Bankswitching schemes BUS, DPC+ and CDFx now work when startup bank randomization is enabled (these schemes now ignore that setting).
• Replaced "Re-disassemble" with "Disassemble @ current line" in debugger.
• Fixed bug when taking fullscreen snapshots; the dimensions were sometimes cut off.
