+- Don't make shortcuts sticky with the exception of Alt+Tab and Cmd+Tab.
+- Add extra USB reports for pressing and releasing the modifiers of shortcuts. This makes the firmware play nicer with Karabiner, RDP, and possibly some other applications.
+- Make scroll key actions always emit a USB scroll event, even when tapped momentarily.
+- When conflicting mouse keys are pressed at the same time, make the most recent key the dominant one.
+- Add key cluster, trackball, and trackpoint firmware images to the firmware tarball.
+- Set sensible default key actions for modules.
+- Make the key cluster scroll and the other modules move the pointer by default.
+- Move from .tar.bz2 to .tar.gz as the firmware release file format because the latter can be attached in GitHub issues.
