Since the latest version is 6.10.8 (instead of a 6.10.1 for instance) I would just go to this latest release.
This is also a better starting point for future upgrades to Mendix 7 or higher.
In general I tend to use the latest version -1 minor, unless the release provides some functionality that will really benefit my application.
In the case of Mendix 6, I agree with Ronald and can recommend 6.10.8 since the patches probably contains fixes you want, making this the most stable version at the moment.
we are having mendix service console 4.3.0 and we dont want to change our existing service console.
Will Mendix 6.10.7 run on Service console 4.3 ?
