Release v4.2.0 Notable changes =============== Switch to ed25519-zebra for consensus signature checks ------------------------------------------------------ This removes the zcashd dependency upon libsodium for ed25519 signature checks and instead uses the Rust implementation in ed25519-zebra, which has been active for signature verification since the Canopy upgrade. For more information on the conditions that led to this change see https://hdevalence.ca/blog/2020-10-04-its-25519am Update default fees according to ZIP-313 ---------------------------------------- Reduce default fees to 0.00001 ZEC as specified in ZIP-313 and ensure that transactions paying at least the new minimum fee meet the transaction relay threshold irrespective of transaction size. Improve getblocktemplate rpc performance when using shielded coinbase --------------------------------------------------------------------- This change precomputes future block templates to permit miners to begin working atop newly arrived blocks as quickly as possible, rather than waiting for a new template to be generated after a block has arrived. It also reduces the initial the wait time for incorporating new mempool transactions into a block from 1 minute to 10 seconds; the previous value was inherited from the upstream bitcoin codebase but is inappropriate for our block timing. Migrate from rpc-tests.sh to rpc-tests.py ----------------------------------------- This unifies and simplifies the RPC testing framework, as has been done in the upstream Bitcoin codebase.
