I'll use this as an excuse to solicit more consumer/app dev involvement in the SIMD process. Would love to see more banter from informed devs around protocol changes! This was discussed in depth as a tradeoff. That said, we have the power to change things. I've heard a lot of complaints about the shorter expiry time, so let's fix it.

Durable Nonces will be deprecated next year! It will move out of the protocol and into onchain programs. Now is the time to try out the new solutions and give feedback to make the tooling around it great for the migration period. Everything you need to know in the deprecation guide: solana.com/upgrades/durable-…

Alpenglow is coming to testnet this week. 🧵 Testnet exercises the exact migration devnet and mainnet-beta will run. The Alpenglow community cluster rehearsed the migration numerous times and has been running Alpenglow for over 4 months.  Now Alpenglow moves to the formal activation path.

Transaction V1 (SIMD-0385) is live on mainnet-beta. Max transaction size grows from 1,232 to 4,096 bytes. ZK proofs, large multisigs, BLS signatures, and confidential transfers that required multiple transactions now fit in one atomic operation. V1 also moves resource requests (compute unit limit, priority fee, loaded accounts data size, heap size) into the transaction header instead of compute budget instructions.
