Hello, an updated plugin for ASCOM cameras is available at:
https://www.msb-astroart.com/down_en.htm#cameracontrol
which fixes a possible problem for 64 bit drivers: sometimes settings were not saved.
If this problem does not affect your camera, there's no need to upgrade now, unless you are using a very old version (2.6 or older) which lacks all the features added in 2.7x versions.
Clear skies, Fabio.
