Yeah that appeared about a week ago. It's taken a long time for the 8MP H13 firmware to be updated. For a long time it's been on a lower version than teh 4MP H13U (now on 5.8.21)
In the release notes that you linked I noticed this:
4. When the camera is directly connected to HC, the playback viewing on HC supports filtering human and vehicle.
That isn't available in the latest version of H13U (4MP). When installing a standalone camera (no NVR) that is very useful.
Does anyone have any experience with connecting the cameras using this firmware to the Axpro ? i have done this many times and the linecross detection has always worked just fine arming and disarming it using the arm/disarm of the AXpro .. However i now have the issue where dispite arm/disarm of the axpro the cameras stay in armed mode . Anyone who can guide me in this ?
