v1.9.0

• MidiKeys is now 64-bit, so it works on Catalina and future macOS versions.
• Minimum system version is 10.11.
• Keys window is resizable (probably the most asked-for feature request).
• Support for system dark mode, including a dark mode keyboard. A "force light keyboard" preference is visible to allow you to revert the keyboard to a traditional appearance.
• Added Clear Stuck Keys command.
• On systems with a trackpad or mouse that reports pressure, MidiKeys will send channel aftertouch when keys are clicked and held.
• New "show C notes" feature that draws "Cn" where "n" is the octave (i.e., C3, C4, etc) on the keyboard.
• Fixed an issue with key caps where certain keys like tab and delete were not shown; they will now appear as the standard key icons.
• Restored and updated German and French localisations.
• Changed version update feed URL to https.
• Updated Sparkle and ShortcutRecorder frameworks to modern versions.
• No longer a universal binary.
