New release: ZEUS v13.0.0

This release features our new graduated wallet experience, a brand new node engine powered by LDK Node, device migration with channels intact, and ...

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.

CDK Release Version 0.13.0 marks a major milestone for mobile development with the introduction of comprehensive native mobile bindings that enable building Cashu wallets for iOS and Android using Swift and Kotlin. The release introduces cdk-ffi, a new Foreign Function Interface crate that provides UniFFI-based bindings for Swift and Kotlin, with full wallet functionality including multi-mint support, BOLT12 payments, BIP-353 address resolution, and advanced features like P2PK conditions and authentication. Mobile bindings are distributed through dedicated repositories at

Delivers end-to-end BOLT12 offers and payments, adds BIP‑353 address resolution for BOLT12 payments, and introduces cdk-ldk-node, an integrated Lightning backend that lets a single binary run both a Cashu mint and a Lightning node with full BOLT11 and BOLT12 support. It also adds a local, admin-focused web UI for cdk-ldk-node with dashboards for channels, invoices and offers, payments, and on-chain activity. On the data layer, the release expands storage with PostgreSQL via the new cdk-postgres crate and accelerates the shared SQL stack (cdk-sql-common) with statement caching and structured, namespaced/global migrations. Operationally, the mint now exposes explicit start and stop lifecycle methods, enabling graceful startup and shutdown of background services. Wallet keyset management has been clarified with renamed APIs that separate local storage from network fetches. The MSRV is updated to 1.85.0.
