Do many software creators tend for a convention on versioning when releasing software? For example Tomcat right now is v9.0.41. We would like to only update our internal stack when "major releases" occur. Would I wait until 9.1.x? I know some softwares call these LTS, but often that is nowhere to be found on their site.

I think this is probably the type of question that could spiral into a bunch of conjecture, but any insight welcome.
