Nostr PHP is a helper library that makes it easier for developers to interact with the Nostr protocol using PHP. This release adds support for NIP-05 lookups, NIP-17 private direct messages, and additional metadata fields for profiles. It also includes a fix for NIP-44, improvements to relay handling via Relay and RelaySet methods, and the removal of the CLI tool from the library. These updates enhance protocol support, simplify integration, and give developers more flexibility when building Nostr-based PHP applications.

Noscrypt is a C-based cryptographic library tailored for Nostr applications. This release introduces versioned CI builds using a new semver format, modernizes Windows crypto API usage, and improves build configurations through updated Taskfiles and CMakePresets. It also updates mbedTLS to 3.6.3.1 and refreshes .NET dependencies for its wrapper. These changes enhance development workflow, ensure better compatibility, and lay groundwork for more stable builds in future updates.

Mostro Core is a Rust-based library that provides peer-to-peer and cryptographic functionality for decentralized applications, forming the foundation for the Mostro daemon. This release introduces encrypted database columns, enhances password handling and privacy logic, and adds a new, more readable crypto.rs module. Improvements also include refined encryption/decryption functions, better memory settings for Argon2, and smarter caching of identity keys. These updates boost security, reliability, and maintainability for developers building on the Mostro protocol.
