This version fixes state difference at block 6701925 of testnet. It also introduces NeoFSStateFetcher service that allows to synchronize contract storage state at particular height based on checkpoint data stored in NeoFS. Moreover, for smooth RPC client upgrade experience, the next Faun hardfork is added in a preview mode (although it doesn't contain any changes yet). Also, new BroadcastTxsBatchDelay P2P application configuration setting is introduced preliminary for custom networks setup to be able to customize the maximum transaction batch broadcast delay.
T5 nodes require DB resynchronisation (or state reset to 6701924 block for full nodes), mainnet nodes DB resync is not required at the moment of release. No configuration changes required.
