0.10.0 — 2026-06-26

Erratum (added post-release, 2026-06-26) — the G2 entry below
predicted Linux/Windows artifact reductions of -600 to -800 KB
from disabling arboard's image-data feature. cargo-dist's
actual output shows the opposite: every platform's artifact grew,
because the new G1/G3/G4/G5 code (forwarding modal, OSC 52 escape
builder, ProxyCommand walker, sort axis, base64 dep) added more
than the image decoders saved. Measured deltas vs v0.9.0:

Target	v0.9.0	v0.10.0	Δ
macOS arm64	1086 KB	1103 KB	+16 KB
macOS x86_64	1216 KB	1233 KB	+17 KB
Windows ARM64	1478 KB	1492 KB	+13 KB
Windows x64	1544 KB	1568 KB	+24 KB
Linux aarch64	1213 KB	1376 KB	+163 KB
Linux x86_64	1351 KB	1515 KB	+164 KB

The image-data strip is still correct in principle (sshc never
reads image clipboards) but the net size win didn't materialise.
v0.11 will revisit with cargo bloat to find the real footprint.

Release Notes

Surface-polish round on top of v0.9. Five goals, all delivered;
two of them (G1 + G2) close lingering v0.9 trade-offs (typed
forwarding was single-entry; arboard pulled in image decoders sshc
never used).

Added

• Multi-entry forwarding via a list modal (G1). v0.9 G5
  introduced typed LocalForward / RemoteForward /
  DynamicForward form rows but only stored one entry per kind.
  OpenSSH lets a host carry several of each; v0.9 cascaded
  duplicates into the freeform extra block as a workaround. v0.10
  upgrades the model end-to-end: each field is now Vec<String>,
  the parser pushes per occurrence in declaration order, the
  serializer emits one line per entry, and the form row opens a
  small list modal (Enter to edit / d to delete / Esc to return).
  Validation per kind matches v0.9 G5 — modal rejects garbage on
  the Enter that tries to add it.

• S cycles the host list sort axis (G5). lazyssh's s/S
  parity, but s is sshc's ssh-connect key, so v0.10 takes S
  (Shift+s) only — one direction, three axes. Cycles
  alias → recent → reachability → alias. Favorites still float
  to the top regardless. Status bar shows the new label after each
  press. Session-only — not persisted across sshc invocations.

• OSC 52 clipboard fallback (G3). v0.9 G4's c copy lived
  directly on arboard, which silently failed on Wayland w/o
  display, in remote SSH sessions, or in tmux without
  set -g set-clipboard on. v0.10 chains: try arboard first, then
  emit the OSC 52 escape (ESC ] 52 ; c ; <base64> ESC \) to
  stdout so modern emulators (kitty, iTerm2, foot, alacritty,
  wezterm) can write the user's host clipboard. Status hint shows
  copied: … (osc52) when the fallback fires so the user knows
  which path won. SSHC_NO_OSC52 disables the fallback for users
  who want to keep their terminal output clean.

• ProxyCommand PATH sanity check in doctor (G4). For every
  host parsed out of ~/.ssh/config (Include chain followed),
  pull the ProxyCommand first token and look it up on $PATH
  (PATHEXT on Windows). When the binary isn't found, doctor
  surfaces a single WARN line aggregating offenders by host
  count, e.g.

  [WARN] proxy commands not on PATH — 'my-corp-helper' (3 hosts)

  Variable-laden tokens (%h, $JUMP) are skipped — we can't
  resolve those without ssh's own substitution layer. Clean
  configs see no extra line.

Changed

• arboard image-data feature off (G2). sshc only ever writes
  text via set_text. Stripping default-features and re-opting
  into just wayland-data-control removes the image and tiff
  decoder crates from the transitive graph (verified via
  cargo tree --target x86_64-unknown-linux-gnu). macOS arm64
  release size barely moves because LTO had already DCE'd the
  unused code path on that target; Linux and Windows artifacts
  drop noticeably (-600 to -800 KB depending on platform). New
  download sizes will land in this release's GitHub artifacts.

Internal

• New module src/ui/forms/forwarding_list.rs (~280 LOC plus 7
  unit tests). Owns its own validate-per-kind helpers; the v0.9
  copies in host_form were dead-code removed.
• New module src/exec/clipboard.rs (copy_to_clipboard +
  OSC 52 escape builder). App::copy_ssh_command_for_selected
  now routes through it; no in-flight v0.9 G4 surface area
  changed.
• Host::local_forward / remote_forward / dynamic_forward
  promoted from Option<String> to Vec<String>. All 8 host
  literal fixtures (model, app/tests, ui/list, ui/preview,
  ui/modal, inline_app, probe, examples) updated. FormPayload
  and build_host follow.
• App.sort_axis is new state with a SortAxis enum cycling
  through three keys. apply_filter rewrites the comparator to
  use it as the secondary key behind favorites and (when present)
  the fuzzy score.
• New dep: base64 = "0.22" (OSC 52 payload encoder, ~+10 KB
  binary impact, scoped to clipboard.rs).
• Two arboard dep cleanups removed image and tiff transitive
  pulls.

Migration

• v0.10-written sshc.conf files with multiple LocalForward /
  RemoteForward / DynamicForward lines on a single host:
  if you roll back to v0.9 (or earlier) and re-save that host,
  v0.9 will keep only the last such line per kind (the cascade
  workaround was last-wins). The data still survives in the
  extra block from the read side, but the typed form surface
  drops it. v0.10 reads its own format and v0.9's format
  identically.

Out of scope (carried into v0.11+)

• Sort axis persistence in state.toml — v0.10 is intentionally
  session-only; user feedback decides v0.11.
• ↑/↓ reorder inside the forwarding list modal — add/edit/del
  only for v0.10.
• IdentityFile multi-value — same shape as the forwarding work;
  v0.11 candidate.
• Hand-rolled clipboard backend (G2 alternative path that wasn't
  needed — arboard with image-data off was enough).
