Prysm version v7.3.1 is a minor patch release focused on the Hoodi testnet.
The main change in this update is the unscheduling of the Glamsterdam (Gloas) hard fork on the Hoodi testnet, which was originally planned for October 26, 2026. This is in response to a broader decision to delay the fork, as explained in a recent Ethereum Foundation blog post.
This release removes the fork epoch (132352), fork version, and associated gas limit parameters from the Hoodi testnet configuration.
Important: Mainnet operators already running v7.3.0 do not need to update to this version.
