# Changelog

## [0.5.0][0.5.0]

Changes for library users since `0.4.2`.

### Added

- Added support for reading OpenSSH private keys encrypted with
`aes128-gcm@openssh.com` and `aes256-gcm@openssh.com`.
- Added `SshClientConfig.sessionWindowSize` and `SshClientConfig.sftpWindowSize`
to configure receive windows for session channels and channels opened by
`SshClient.openSftp` independently.

### Changed

- Increased default receive windows from 64 KiB to 2 MiB for session channels
and 8 MiB for SFTP channels to improve throughput on higher-latency connections.
- Improved SSH and SFTP transfer performance by batching channel writes and
receive-window updates, pipelining SFTP frames, and reducing buffer copies
and allocations.
- Serialized protocol decisions independently of transport writes, keeping
incoming packet processing and shutdown responsive under backpressure.

### Fixed

- Prevented valid packets arriving during suspended writes from causing
spurious disconnects by serializing complete connection state transitions.
- Preserved reply ordering when requests are cancelled after being admitted
for transmission.
- Released SFTP lifecycle locks before waiting for writes to prevent deadlocks
under transport or channel-window backpressure.
- Cancelled pending remote forwarding handlers and released sockets and
selector resources when forwarding ends or fails.
- Improved Android key compatibility by falling back to JVM Base64 operations
when Android calls fail and accepting Ed25519 private keys with PKCS#8
encodings regardless of their implementation class name.
