Arista Networks' EOS™ Software Release Policy and Life Cycle guidelines help customers and partners facilitate EOS migration and plan multi-year infrastructure deployment. Arista will support each major EOS software release for up to 36 months from the date of initial posting for a particular train.
To assist customers in selecting the right EOS software release for their environments, Arista follows a standard naming convention for EOS releases. The naming convention identifies if a particular release is integrating new feature functionality, or has reached software maintenance mode.
Each EOS software release is identified with either the letter "F" indicating that the release contains new Functionality or "M", denoting that the release is in the Maintenance phase. An M release only receives incremental fixes and no new functionality is added.
New Feature Phase
- EOS software releases will be identified with the letter "F" indicating that the release contains new feature/functionality.

Maintenance Phase
