how can i find version history info about Active Directory Right Management Service

I am reaching out to request detailed information regarding the release dates and end-of-life (EOL) timelines for all versions of Active Directory Rights Management Services (AD RMS). Additionally, I would like to confirm whether version 2.1 of AD RMS is still supported.

To summarize, I am looking for the following:

1. A complete list of all AD RMS versions, along with their respective release dates and EOL information.
2. Confirmation on whether AD RMS version 2.1 currently receives support, including details about any extended or limited support options.

Your assistance in providing this information would be greatly appreciated. If additional documentation or steps are required, please let me know.
