Latest MLNX-OS update on CS7520

Hello,

I have Mellanox CS7520 Switch with the current MLNX-OS 3.7.1134. I would like to upgrade to a newer version. The latest version lists on NVIDIA website is 3.12.xxx. Can you please let me know what is the correct latest version to can upgrade to? Thank you very much.

CS7520 has been End Of Life. From what I can see, the last image which supports CS7520 is 3.10.4500.
