TL;DR: The 4.5.0, 4.5.1, and 4.5.1-1
zcashd nodes will reach End of Service on or about January 10, 2022. Prior to that time, all testnet and mainnet nodes should upgrade to 4.6.0 or later release.
From this release, newly-created wallets will save the chain name (“Zcash”) and network identifier (e.g. “main”) to the
wallet.dat file. This will enable the
zcashd node to check on subsequent starts that the
wallet.dat file matches the node’s configuration. Existing wallets will start saving this information in a later release.
Two new APIs have been added to this library (
zcash_script_legacy_sigop_count_precomputed), for counting the number of signature operations in the transparent inputs and outputs of a transaction. The presence of these APIs is indicated by a library API version of 2.
getblocktemplateRPC method output now includes a
defaultrootsfield, which provides various tree roots and block commitments matching the contents of the block template. If any part of the block template marked as
mutablein the RPC method output is mutated, these roots may need to be recomputed. For more information on the derivation process, see the block header changes in ZIP 244.
- Fixed an issue where
ERROR: spent index not enabledwould be logged unnecessarily on nodes that have either
-lightwalletdconfiguration options enabled.
getmininginfoRPC now omits
currentblocktxwhen a block was never assembled via RPC on this node during its current process instantiation.
