Hello @papita.marcel.rares, the only issue is once you upgrade studio, you must upgrade your assistant as well because newer projects won’t be able to run on an older assistant version.
Additionally, when you open your previous projects up in the updated version of Studio, you may be prompted to upgrade dependencies. 9 time out of 10 there should be no problems, and none of your existing/deployed automations will be impacted. Its safe overall. I’ve updated multiple times with little to no issues.
