Release Notes

Feature round + a measurable size win after eight v0.8.x patches.
Three sources fed v0.9: operational hardening leftover from the
v0.8 cycle, UX ideas borrowed (selectively) from Adembc/lazyssh,
and a long-deferred dependency cleanup.

Added

  • doctor surfaces CRLF in ~/.ssh/config (G1). When the user
    copies a config off a Windows host or saves it through an editor
    whose files.eol is CRLF, OpenSSH treats \r as part of an alias
    token and every Host match silently fails. doctor now scans the
    first 100 lines and emits a WARN with the exact tr -d '\r'
    fix. Clean configs see no extra line.
  • doctor surfaces nested Include scope (G2). Pre-v0.8.4
    installs (and any user who hand-edits the ~/.ssh/config block
    sshc injected) can end up with the Include line nested under a
    Host <pattern> stanza. OpenSSH then only fires sshc.conf for
    that alias, making every sshc-managed host invisible to
    ssh <other-alias>. doctor identifies the offending stanza, names
    it in the warning, and suggests adding Match all directly above
    the Include — or re-running sshc -m → i on v0.8.4+ which
    emits the terminator automatically.
  • Sticky-on-error status messages (G3). The single most painful
    failure mode of the v0.7–v0.8 cycle was status messages getting
    overwritten by the modal-close redraw before the user could see
    them. Split StatusMessage into Info (v0.6 transient, 3 s
    timeout) and Error (stays visible until the user's next
    keystroke). All seven real failure paths (apply_form, persist,
    ssh -G, include injection, etc.) now use Error; routine
    confirmations stay Info.
  • c copies a one-line ssh command (G4). Pressing c on a
    selected host runs ssh -G <alias>, reduces the dump to
    ssh user@host -p port -i key (dropping defaults like port 22 or
    empty identityfile), and pushes the line onto the system
    clipboard via arboard. Useful when sharing a connection string
    with someone who doesn't have your ~/.ssh/config. Clipboard
    failures (Wayland w/o display, etc.) surface as a sticky Error so
    the line isn't silently dropped.
  • Typed Forwarding form fields (G5). The add/modify host form
    grows from 7 to 10 fields with a dimmed ─── Forwarding ───
    section header between Tags and the freeform Options field, and
    a ─── Advanced ─── header above Options. LocalForward,
    RemoteForward, and DynamicForward are now typed
    Option<String> values on Host, parsed and serialized
    round-trip. Loose validation matches OpenSSH's
    [bind:]port host:hostport (Local/Remote) and [bind:]port
    (Dynamic) shapes; deep validation is left to ssh on connect
    (anti-feature 5: no full config(5) parser). Multi-directive
    hosts keep their extras in the free-form extra block so the
    round-trip is lossless.
  • g TCP reachability probe (G6). Distinguishes "host is down"
    from "ssh config is wrong" without spawning ssh. g resolves the
    selected alias through ssh -G (reusing the v/c cache),
    attempts a raw TCP connect to the hostname:port endpoint with a
    2-second budget, and reports either a sticky ✗ TCP unreachable
    error or a transient ✓ TCP reach: host:port (N ms). nc -z
    semantics — reachability ≠ authentication, anti-feature 1 stands.
  • Windows ARM64 release artifacts (G8). cargo-dist now produces
    sshc-aarch64-pc-windows-msvc.zip alongside the existing
    x86_64 Windows artifact. The PowerShell installer routes
    ARM64 hosts to the matching binary automatically.

Changed

  • HTTP/TLS: ureq + native-tls, explicitly wired (G7). v0.8.0
    shipped ureq with default rustls + webpki-roots after the
    initial native-tls attempt died with "no TLS backend is
    configured". v0.9 closes that loop by handing AgentBuilder an
    explicit tls_connector — the step v0.8 R6 missed. The release
    binary on macOS arm64 shrinks from 5.95 MB (v0.9 R6, with
    arboard + new exec/ surface) to 3.76 MB (-2.18 MB), well
    under the v0.7-era baseline of 3.0 MB even with everything v0.8
    added on top. Dropping ring as a transitive dependency also
    unblocked cargo check --target x86_64-pc-windows-msvc from
    macOS hosts (broken since v0.8 R6 — see the
    docs/WINDOWS_DEBUG_HANDOFF.md rant for context).

Internal

  • host_form row layout split into a small Row enum so section
    headers (Forwarding, Advanced) participate in the layout
    without confusing Tab routing.
  • FormPayload + FormOutcome pick up #[allow(clippy::large_enum_variant)]
    rather than the boxing dance — both are stack values with
    one-call lifecycles.
  • All 8 Host literal fixtures (model, app/tests, ui/list,
    ui/preview, ui/modal, inline_app, probe, examples) gained the
    three new forwarding defaults.
  • New module src/exec/tcp_reach.rs houses the G6 reachability
    helper. Network surface stays in src/exec/*.
  • doctor's Path import is no longer cfg(unix)-gated (G2 uses it
    on every platform).
  • ~/.cargo/bin/sshc 0.9.0 doctor smoke run: 7 PASS lines, including
    the update check landing through native-tls.

Out of scope (carried into v0.10+)

  • Multiple Forwarding directives per host (G5 takes the last and
    cascades the rest into extra; round-trip is preserved).
  • Self-built SSH client, SCP, key deployment — anti-features 1 + 2
    still stand; lazyssh's roadmap items in that direction are
    intentionally not mirrored.
  • Always-on / startup update check — anti-feature 4 stands. g for
    reachability is the user-driven probe; the GitHub Releases call
    fires only inside --doctor.
