CDK release v0.14.0
Summary
This release focuses on reliability and robustness improvements across the codebase. The mint now implements saga patterns for both melt and swap operations, providing better error recovery and state consistency during these critical operations. Async melt processing has been added for improved throughput. The wallet gains a new Tor mint connector with isolated circuits support for enhanced privacy when communicating with mints, along with a MintMetadataCache that delivers significant performance improvements for key and metadata management. A new proof recovery mechanism automatically handles failed wallet operations. MultiMintWallet receives improvements including the ability to check and wait for mint quotes and configure internal wallets. NUT-11 SIG_ALL message aggregation has been updated to match the latest specification. On the infrastructure side, a generic pubsub module has been introduced in cdk-common, and cdk-ffi adds postgres support. Additional highlights include keyset amount tracking and SQL balance calculation optimization for improved performance, wallet functions to pay human readable addresses (BIP353 and Lightning address), invoice decoding for BOLT11 and BOLT12 in the FFI bindings, and a mutation testing infrastructure to ensure security-critical code coverage. The release also brings numerous bug fixes addressing database contention, HTLC witness handling, and quote state management.
