1.0.0

Released: 2026-05-25

Summary

Traversio 1.0.0 establishes the first public Swift package API for Apple apps that need native Swift SSH, SFTP, SCP, forwarding, proxy routing, host-key trust, and diagnostics.

Public API Surface

The initial API includes:

• encrypted SSH transport with the documented algorithm profile
• explicit host-key trust
• password, keyboard-interactive, public-key, callback-backed, and SSH-agent authentication
• OpenSSH private-key loading and OpenSSH-compatible key generation
• command execution, streamed exec, named subsystem startup, and PTY shells
• SFTP metadata, file handles, reads, writes, mutations, recursive helpers, resumable helpers, and selected OpenSSH extensions
• single-file SCP receive/send helpers
• raw direct TCP/IP and streamlocal channels
• local forwarding, dynamic SOCKS forwarding, remote TCP forwarding, and remote streamlocal forwarding
• SOCKS5 and HTTP CONNECT connection proxies
• ProxyJump
• structured errors, log handlers, OSLog helpers, support reports, and route-aware SSH port latency diagnostics

Release Hardening

This release also adds:

• public OpenSSH private-key metadata inspection with SSHOpenSSHPrivateKeyInfo
• a public API baseline check through Tools/check-public-api.sh
• release metadata checks for TraversioRelease.version, source package tags, and SSH client identification
• public documentation for connection lifecycle, cancellation behavior, forwarding shutdown, and support diagnostics

Not Included

This release does not include:

• library-owned automatic reconnect
• local ssh_config parsing
• mandatory built-in trust-store persistence
• mandatory Keychain-backed credential or trust storage
• hostbased authentication
• security-key authentication
• X11 forwarding
• auth-agent forwarding
• recursive SCP
• broad legacy algorithm compatibility beyond explicit ssh-rsa
• release-quality benchmark comparisons
