• It is now possible to define macros and trigger them through mappings. This allows for previously impossible things like mapping a button to double-click or having one key type some text.
• Mappings can now be present on more than one layer, which could reduce the number of mappings required in some configurations.
• Unmapped input passthrough now also works on layers other than 0 and can be enabled or disabled on each layer individually.
• Layer activating mappings are no longer implicitly present on all layers, but they are still forced to be present on the layer they activate.
• Some bugs related to sticky mapping handling were fixed.
