 ### Added
-* Check current limit violation: added `ERROR_CURRENT_UNSTABLE`, `motor.config.current_lim_tolerance`.
+* Simplified control interface ("Input Filter" branch)
+    * New input variables: `input_pos`, `input_vel`, and `input_current`
+    * New setting `input_mode` to switch between different input behaviours
+      * Passthrough
+      * Velocity Ramp
+      * 2nd Order Position Filter

+* [CAN Communication with CANSimple stack](can-protocol.md)
+* Gain scheduling for anti-hunt when close to 0 position error
+* Velocity Limiting in Current Control mode according to `vel_limit` and `vel_gain`
+* Current limit violation added `ERROR_CURRENT_UNSTABLE`, `motor.config.current_lim_tolerance`.
+* Regen current limiting according to `max_regen_limit`, in Amps
+* DC Bus Power limiting according to `power_supply_wattage`
+* Unit Testing with Doctest has been started for select algorithms, see [Firmware/Tests/test_runner.cpp](Firmware/Tests/test_runner.cpp)
+* Added support for Flylint VSCode Extension for static code analysis
+* Using an STM32F405 .svd file allows CortexDebug to view registers during debugging
