we recently added Ubuntu support to the connector. This was also a major step, as the connector now is not depending on a deep kernel integration any more. This makes the support for other Linux distributions easier. Behavioral Protection engine was added to the connector, which was a major step for detection and meeting ATT&CK criteria.
The next big step will be the unified endpoint: this means AMP4E, Umbrella, Any Connect and DUO will be included in one single agent.
For any other stuff, you may ping your Cisco representativ getting more insights into the official roadmap.
