Maintenance/patch versions are typically made available once per month, with the exception of months with major/minor releases.
The patch releases typically contain updates to the default preset and imagery layer configuration. Both of these can be updated manually without an update, but that increases the amount of phoning home and simply updating the app avoids that.
In the run up to a major or minor release we typically provide at least one beta/test version.
Over the years feedback on these has dwindled to zero. It isn't as if there are no installs, we typically have multiple 100s of users on the beta versions, there is just literally no feedback.
The issue fixing that does happen at this stage tends to nearly all be driven by dog fooding.
Anyway, next major version 21 likely in Q1 2025.
