+## [5.0.1] - 2017-12-09
+
+Data Model: 4.0.0 (unchanged) | USB Protocol: 2.0.0 (unchanged) | Slave Protocol: 3.0.0 (unchanged)
+
+ - Make key presses continue to emit scancodes even if a USB interface (typically the mouse interface) is not polled by the host anymore.
+ - Make scrolling always immediately react to keypresses regardless of the previous internal scroll state.
+
+## [5.0.0] - 2017-12-04
+
+Data Model: 4.0.0 (major bump) | USB Protocol: 2.0.0 (unchanged) | Slave Protocol: 3.0.0 (unchanged)
+
+- Move pointerRole from keymaps to module configurations as pointerMode. Add angularShift, modLayerPointerFunction, fnLayerPointerFunction, and mouseLayerPointerFunction to module configurations. `DATAMODEL:MAJOR`
+
+## [4.0.0] - 2017-11-30
+
+Data Model: 3.0.0 (major bump) | USB Protocol: 2.0.0 (unchanged) | Slave Protocol: 3.0.0 (unchanged)
+
+- Implement mouse movement and scrolling deceleration and acceleration.
+- Toggle layers upon double tapping their keys. Make the double tap timeout configurable.
+- Make the parser read additional user configuration properties: dataModelMajorVersion, dataModelMinorVersion, dataModelPatchVersion, doubleTapSwitchLayerTimeout, iconsAndLayerTextsBrightness, alphanumericSegmentsBrightness, keyBacklightBrightness, mouseMoveInitialSpeed, mouseMoveAcceleration, mouseMoveDeceleratedSpeed, mouseMoveBaseSpeed, mouseMoveAcceleratedSpeed, mouseScrollInitialSpeed, mouseScrollAcceleration, mouseScrollDeceleratedSpeed, mouseScrollBaseSpeed, mouseScrollAcceleratedSpeed. `DATAMODEL:MAJOR`
