Solana Devnet (Agave v4.2 Upgrade)

Scheduled for Aug 7, 11:00 UTC  -  Aug 8, 11:00 UTC

Scheduled

Scheduled maintenance for the Agave v4.2 upgrade on Solana Devnet.

This upgrade includes a few client-facing changes worth noting ahead of time:

Token-2022 confidential transfers:
depositConfidentialTransfer/withdrawConfidentialTransfer instructions in jsonParsed responses will emit a single account field instead of separate source/destination fields. If your integration parses these fields directly, you may need to update your parsing logic.

getClusterNodes:
Results will no longer be filtered to your own shred version, and the shredVersion field will reflect each peer's own value rather than a constant. Expect more entries in the response, with heterogeneous shredVersion values.

Reward parsing:
A new rewardType value (DeactivatedStake) may appear in getInflationReward and getBlock/getBlockProduction responses. Additionally, the commission field in reward data may return null in some cases going forward.

We recommend reviewing your integration against these changes ahead of the Mainnet rollout on August 10.
