any updates on this?

Hi, unfortunately no - not yet. We are addressing all the issues we have in versions V15-V20 as these are the main versions used for our own needs/projects internally and used mainly for other users as well - as we see it in logs. However, we will be getting into V21 in Q4 of 2026 or Q1 2027. As soon as there is release with support of V21 - it will be released here on GitHub. BR
