Note - Features like UDF and Generic header filtering are delivered for NVIDIA Spectrum-2 and Spectrum-3 devices.

## Release 2.1.0

* Minor Changes in CLI commands as per our unique framework, the OPB-NOS CLI commands are modified. See below the table for keyword changes and commands affected. The CLI command changes do not affect any control or data plane functionality of OPBNOS.
* Image upgrade to 2.1.0 from the lower version via OPB-NOS CLI, will have configuration loss related to the “old” keywords. The Suggested recommendation is to upgrade the OPBNOS using ONIE and manually re-configure the device for existing deployments.
