• Gateway operator improvements including availability tracking, custom fee configuration, bitcoind support, and force close capabilities (#7736, #7758, #7680, #7690)
• Guardian enhancements with configurable absolute base fees, password changes, and config backup downloads (#7749, #7725, #7745, #7691)
• Iroh networking performance and stability improvements including connection reuse, optimized join times, and enhanced monitoring (#7804, #7816, #7710, #7785, #7778)
• New fedimint-client-rpc provides dedicated RPC interface for client integrations with built-in backup and recovery support (#7499, #7605)

Breaking Changes

Library users must initialize crypto provider. Applications using fedimint as a library must call the following at startup before any TLS connections:

:::rust
fedimint_core::rustls::install_crypto_provider().await

Required due to rustls 0.23 upgrade removing the implicit default crypto provider. (#7554, rustls v0.23.0)
