However, in some cases we recommend you uninstall once any current projects using a version are completed.
Or, in the case sometimes of issues fixed in a subsequent version, we do recommend moving to the fix version and uninstalling the older one so that you do not accidentally open the scene in the wrong version. For example v5.7.1 resolved some issues in v5.3 so v5.7.1 should be used and v5.3 uninstalled. V5.7.2 is the recommended version because of some enhancements and a fix on v5.7.1. Phew
Check the Release Notes
published for each update, and if in doubt, then ask about moving to a newer version.
So, (briefly) V5.7.2 is the current and recommended version, and all prior versions should be uninstalled.
