OEM version versus plugin version
I'm wondering how the versioning of OEM plugins works compared with the OMS version. When I look into the plugin directory, we have 10 plugins.
The named plugins in that folder contain a version name, and some of them do not have the version of OMS istelf. Actually, there are 3 different versions listed there, one of them being the latest version (13.5).
So my question is : does every pluging needs to be upgraded, when OMS is upgraded ?
