Likewise - no issue going from 4.4.1.1 to 4.4.2 for me...

Also no issues going from 4.4.1.1 to 4.4.2 on a 2865.

With regard to the release notes omitting known issues:

A firewall can restrict/drop unwanted inbound WAN traffic such as VPN requests. The
router's firewall block rules can stop remote management and VPN access. It is
recommended to review the firewall settings before upgrading.

This was noted in previous release notes (4.4.0), however I do agree that the other three items should be included, it might be that as they were not included in the previous release (security) they have not been carried forward, although this depends on when they were found or introduced.

It still blocks IKE traffic unless the endpoint is allowed in the firewall rules (not end of the world)

At least it doesn't block access to Cyren Services like 4.4.1. This broke my web filtering, which is why I ended up on the beta firmware from Draytek support!

4.4.1 also broke the ability of the firewall to ping external servers for the WAN interface monitoring! That was also annoying. Couldn't get my DSL or 5G WAN to work until I realised I had to explicitly put them in the firewall. This was fixed in 4.4.2 also as I don't need to put those in anymore.

Happy with 4.4.2 so far. First official realease firmware I have been able to even use on my router!

4.4.2 Still going strong for me
