Hi Dominik,

If I understand your question correctly, you’re looking to know if you’re using a software version from the Main Release or Feature release.

A main release won’t increment the last number of the version, like 9.6.0, 10.0.0 and 10.1.0.

A feature release increments the last number of the version, like 9.6.13, 10.0.12.

There’s a 3min video from Simon that clarifies how this is organized: Agents – DataMiner versioning & upgrade – DataMiner Dojo

Further details about the differences between a main and feature release can be found at: DATAMINER MAIN RELEASE VS. FEATURE RELEASE – DataMiner Dojo

I also recommend you to have a look in our FAQ Maintenance & Support where you can read when DataMiner version is no longer supported.
