Hi network engineers,

I would like to understand what the main differences are between 4.21, 4.22 and 4.23.
I am planning to upgrade current Arista switches so I need to make a decision which train we can take for our environment.

Hi Yongate,

Each train brings new features.
Within a train, you have several features releases until it reaches maintenance only.

See details here:

You have to balance between feature needs (brand new features?), and code maturity (stability)

Regards,
Alexis
