0.1 Alpha

First public release
Coordinate transformation system ready
Homing not supported but machine can be manually homed and calibrated with M362 GCode
M360 command for changing coordinate transformation mode from cartesian to angular positioning
M361 command for setting joint angles individually, for shoulder and elbow
M362 command for setting current position (similar to G92)
M364 command for getting current X-SCARA version

0.2 Alpha

Moved to Beta stage: all basic functionality (homing, bed-leveling, EEPROM configuration) implemented & working
Added coordinate transformation modes to support bed-leveling (M360 M2 - probe mode)
Activating M1 angular coordinate transformation mode automatically on G28
Activating M2 probe coordinate transformation mode automatically on G29
Implemented homing sequence G28 (X,Y axis are set as codependent by default, shoulder homes first)
Modified UBL (Unified Bed Leveling) to support X-SCARA's kinematic model
Integrated bed-leveling support G29 (requires NOZZLE_AS_PROBE and SCARA_PROBE_OFFSET_DEGREES configurations)
Applying bed leveling for planar moves when bed-leveling is activated
Modified M665 for configuring:
- M665 D - number of segments per second for G1 segmented moves
- M665 M - minimum segment length in mm for segmented moves
- M665 X Y - setting bed center origin relative to shoulder axis (default SCARA_OFFSET_X and SCARA_OFFSET_X)
- M665 E S - setting home offset in degrees for shoulder and elbow joints (required for precise calibration)
M50x EEPROM commands supported to save, load and reset the values configured with M665
