I am looking to patch my Plant Simulation 12.2.2, and I see that going just by the version numbers the latest version is 12.2.5 released in December 2016, however just yesterday a version 12.0.11 was released.
Which version is newer and has the most bug fixes, given the versioning and release dates?
We release maintenance packs only for supported versions.
For major releases the last two major releases (currently 12.0 and 13.0) are under support.
Minor releases are supported for one year after the release.
12.2 is therefore no longer supported and 12.2.5 is the latest released maintenance pack for this version.
