Inventor 2019.4 is an update that lets you work with others who are on Inventor 2020. This update also makes some changes to the Constraint command.
AnyCAD for Inventor
Reference Future (newer) Versions of Inventor Part and Assembly Files
You can now reference an Inventor 2020 part or assembly file in Inventor 2019.
You must have Inventor 2019.4 installed to support opening 2020 part and assembly files. Inventor 2019.4 can be downloaded via the Autodesk desktop app or from https://manage.autodesk.com.
Use the Open, Place, or Derive command to create a reference to a future version of an Inventor part or assembly file.
Migration: If you open and save the file in a newer version of Inventor (or use Task Scheduler to migrate files with references to future versions) the future version references are migrated to standard Inventor Place and Derive relationships.

Enhancements to Assembly Constraints
When placing a mate constraint between 2 axes, Inventor now predicts the best match based on the selection with minimal rotation and assigns the optimal selection before displaying the preview.
For example, if you select axis 1 with a direction and then select axis 2, the relative position with minimum rotation is maintained with the type of direction (opposed or aligned) specified. This allows you to add a manual control to prevent the components from orienting incorrectly.
For more information on placing constraints between 2 axis, see To Place Mate or Flush Constraints in Assemblies.
