Aseprite v1.3-rc1

Hello asepriters! :art: After several months we’re preparing the first release candidate to finally move forward to v1.3 (and leave v1.2 behind :wave: ). If everything goes well (and probably with a couple of extra release candidates) we will finally put v1.3 in the main channel (and the beta channel will be used to bring new features quickly).

Remember to get this update from the beta channel right now. A list of changes and fixes in this v1.3-rc1:

• Prefer native file dialog by default on Windows & macOS

  • macOS: Fixed shortcuts for Edit actions when the native file dialog is displayed
  • You can switch back to the Aseprite file dialog unchecking the Edit > Preferences > Experimental > Use native file dialog option
