This version contains improvements to MC_CamIn and forecast functionality for single axis and master/slave movements.

New cam features include distance based ramping in, the segment type Poly7, and a CamBuilder API to programmatically create Cams.

The forecast functionality provides a forecast of the axis movement with high resolution timing. That means you can execute an action a given time (e.g. 100 ms) before an axis reaches a given position. And you can query the position, velocity, acceleration, and jerk that an axis will have at a given time.

By serving as a gateway, this version enables proprietary add-ons to connect to IO-Link devices.

Fixed issues in certain cases when using pack_mode attribute on ARM based devices.

Support new functionality standardized in BACnet standard ASHRAE 135-2020 and protocol revision 25.

Update of "CODESYS Application Composer Single License" only, no functional changes. This update is necessary for running "CODESYS Application Composer" (any version) in SL-mode on any new CODESYS versions starting with V3.5 SP19 Patch 3. It cannot be used with older CODESYS versions. For using "CODESYS Application Composer" with older CODESYS versions, use the old "CODESYS Application Composer Single License".
