We currently do not have any plans to have geopackages implemented into MAPublisher, however, I am happy to get this filed with our development team for their review! If we do get this implemented in a future release, we will let you know via email!
If you have any other questions or problems in the interim, please don’t hesitate to reach out to us via support.avenza.com
Adobe released an update to Illustrator 2021 (v25.3) that includes native support for M1 Devices and Rotate Artboard functionality. Please note these features are not yet supported within MAPublisher at this time. See compatibility notes.
