Sunset v0.6.0

Sunset 0.6.0 - 2026-08-02

Changed

• Updated all crypto crate dependencies. Most are new major versions,
  RSA is a release candidate. RSA now has a 8192 bit limit.

• Update to getrandom 0.4. This has a new API for custom backends,
  see getrandom docs or picow demo. No changes needed for std.

• Fingerprint no longer has a hash argument, it's always SHA-256.

• Error::bug() now returns a Result rather than sunset::Error.

• sshwire::UnknownVariant now is used to indicate decoding
  an unknown variant. sshwire::EncodeUnknown is the old meaning.
  packets::Unknown type is now moved to sshwire::Unknown.

Fixed

• ssh-key feature is properly optional, previously it would always
  be enabled by various other features.

Added

• Re-export API crates such as public key types, embedded_io_async,
  sunset, sunset_async.

• SSHEncode/SSHDecode are implemented for std::String.

• Document ServEvent username fields, and guarantee it
  will be unchanging.

• Allow ECDSA-256 for SignKey::generate.

• SSHEncode/SSHDecode implemented for SignKey.

Removed

• &[u8] no longer implements SSHEncode/SSHDecode.
  Use BinString instead which is more explicit.

sunset-sftp 0.2.0 - 2026-08-02

Changed

• SftpHandler now takes REQ_BUF and RESP_BUF size parameters
  and allocates the buffer internally. Constructors are const to allow
  static allocations.

• SftpHandler::process_loop has been renamed to SftpHandler::run.
  That now takes a SftpServer argument.

• Changed SftpServer trait, replaced OpaqueFileHandle parameter.
  Now FileHandle or DirHandle types are used as handles by
  the application, wrapping a u32.

• Generic parameters on SftpServer trait methods have changed.

• SftpError variants have changed.

Fixed

• Packet decoding is better at handling unknown packet types. Previously
  the stream could get into an unrecoverable state if unknown packets
  were received across buffer boundaries.

sunset-async 0.6.0 - 2026-08-02

Added

• run_tokio() and run_futures_io() methods on SSHServer
  and SSHClient take AsyncRead and AsyncWrite.
  These require tokio or futures-io features.

• From<ChanInOut> conversion for ChanIn and ChanOut.

• Re-export sunset and embedded_io_async.

sunset-stdasync 0.6.0 - 2026-08-02

Changed

• Update for new sunset release

Added

• Re-export sunset and sunset_async

sunset-sshwire-derive 0.3.0 - 2026-08-02

Added

• Allow enum struct and tuple variants.

• Allow #[sshwire(unknown)] on unit variants, discarding the name.

• Add #[sshwire(decode_unknown_fail)] to return an error instead
  of storing unknown variants.

Changed

• Encoding an enum returns WireError::EncodeUnknown

Fixed

• Don't warn about .finish() when derive fails.
