We are glad to announce that the migration to Aave Governance v2.5 (proposal 355) has been fully executed and a.DI (Aave Delivery Infrastructure) is now active everywhere (including Avalanche) as a cross-chain governance solution of Aave 
Regarding the final Governance v3 activation, everything is going as per the timeline defined in the previous post: currently MixBytes is doing an additional review on the voting assets (AAVE, stkAAVE and aAAVE), and once finished, we will proceed with the extra governance proposals required.
