v22.1.3

Cosanta Core v22.1.3

Cosanta Core v22.1.3 includes the changes introduced across the v22.0.x and v22.1.x release series, together with additional stability, performance, networking, and build improvements.

Highlights

• Added support for Asset Unlock transactions and updated withdrawal validation rules.
• Enabled encrypted BIP324/v2 P2P connections by default, with automatic fallback to v1 peers.
• Improved network diversity, onion connectivity, peer selection, and resistance to eclipse and partition attacks.
• Improved deterministic masternode list and quorum rotation performance.
• Added persistent UTXO locking in both RPC and the graphical interface.
• Improved responsiveness for large wallets.
• Updated build tooling, platform compatibility, and release packaging.

Consensus and Platform withdrawals

• Added the withdrawals deployment and its updated consensus validation rules.
• Asset Unlock validation can use all 24 active quorums and the most recent inactive quorum.
• Increased the withdrawal limit to 2,000 COSA per 576 blocks.
• Updated protocol requirements for nodes and masternodes.

P2P and networking

• Enabled BIP324/v2 encrypted P2P transport by default. Connections automatically fall back to v1 when the remote peer does not support v2.
• Fixed v2-to-v1 downgrade handling for mixing and masternode probe connections, reducing unnecessary connections and masternode load.
• Nodes with onion connectivity now maintain and protect at least two outbound onion connections.
• Multi-network nodes attempt to maintain at least one outbound connection on every reachable network.
• DSQ messages are relayed through the inventory system to reduce bandwidth usage.
• Increased the compressed block-header request limit from 2,000 to 8,000.
• Ports below 1024 and other commonly authenticated service ports are avoided as peer service ports.
• Updated the isdlock cycleHash field to identify the signing quorum's DKG cycle start block.

Quorums and masternodes

• Optimized quorum rotationinfo and GETQUORUMROTATIONINFO by building diffs progressively from oldest to newest.
• Corrected baseBlockHash handling in quorum rotation responses.
• Improved deterministic masternode list processing and the performance of RPCs such as protx diff.

Wallet and CoinJoin

• Added the coinjoinsalt RPC with get, set, and generate operations.
• Persistent locks are now supported by lockunspent and survive node restarts.
• UTXOs locked through the graphical interface are stored persistently.
• Improved graphical interface responsiveness for large wallets.
• Fixed a potential CoinJoin test deadlock caused by wallet transaction scans under the wallet lock.
• Fixed CoinJoin balance disclosure in discrete mode.

RPC changes

• Added getislocks to retrieve InstantSend lock data in JSON and binary hexadecimal formats.
• Added a binary hex field to getbestchainlock.
• Added descriptor-wallet support to governance votemany and governance votealias.
• createwallet now requires load_on_startup to be set explicitly for descriptor wallets.
• Renamed the getblockfrompeer named argument from block_hash to blockhash.
• Removed deprecated protx *_hpmn aliases in favor of protx *_evo.
• Updated quorum dkgsimerror to accept an integer rate from 0 to 100.
• coinjoin stop now reports an error when no mixing session is active.
• Updated transaction JSON output so creditOutputs entries are objects rather than strings.
• Deprecated top-level mempool fee fields in favor of the fees object.

GUI and configuration

• Added an option to enable RPC server functionality from the graphical interface.
• Added dark-mode appearance support on macOS.
• Extended -walletnotify with %h for block height and %b for block hash.
• Added human-readable units to -maxuploadtarget.
• Added StatsD batching and queueing controls.

Build, compatibility, and tests

• The minimum supported glibc version is 2.31. Ubuntu 18.04 and RHEL 8 are no longer supported.
• Improved FreeBSD build support.
• Updated macOS packaging and notarization support.
• Pinned the QEMU version used by container builds to avoid segmentation faults.
• Improved regtest and devnet activation controls through -testactivationheight.
• Fixed debug-build assertions for coinbase transactions in simplified masternode list diffs.
• Improved CoinJoin test stability and deterministic coverage.

Upgrade notes

Shut down the previous version completely before replacing the binaries. Downgrading to a version older than v22.0.0 may require a full reindex.
