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