Hey David
It’s complicated. The latest official release is 0.8.23-hotfix1 (from late last year) but we have unofficially released 0.9.0, 0.9.1, and 0.9.2 so far this year. So 0.9.2 is the latest release.
See the following announcement for release notes and the reason why we haven’t officially released these versions to the community yet.

We have started development on 0.9.3 and I think the plan is for that to be ready by the end of the year.
