UAT (community)	Samuel Leathers	⏳		We encourage our early adopters to look into the below scenarios as part of the UAT for the current tag: scenarios with different node versions, different P2P settings (only with Legacy/P2P relays, with a mix of relays) tests confirming that stake pools with P2P Single Relay does not have a competitive (dis)advantage tests with stake pools having different node versions and P2P settings (1 relay with 1.35.4 and another one with 1.35.6 + P2P Single Relay) renewal of certificates and restart of the nodes
Audits	Kevin Hammond	✔️		All reviewed audits for this release were successfully finalized.
Mixed settings/versions tests	Moritz Angermann, Jean-Baptiste Giraudeau			Not planned (complex/insufficient tooling)
