One new capability, plus a focused fix pass on the terminal in full-screen programs. External agents (macOS) • New MCP service: expose the hosts you have already configured in Shellby to AI coding tools on your desktop (claude-code, codex and the like), without them needing your passwords, private keys or jump-host setup • Everything exposed in this release is read-only: list hosts, run read-only commands, read remote files, fetch metrics. Mutating commands are refused, with the reason given • Listens on this machine only, checks a token on every request, keeps that token in the Keychain, and records every call in an audit log • Reuses sessions you already have open rather than opening new ones • Settings → External Agents gives you the connection command, ready to copy Terminal • Scrolling finally works in tmux, vim and less — the wheel and swipes previously did nothing at all, even with mouse on enabled in tmux • iPhone & iPad: swipe to scroll in full-screen programs too • Going to the background is reported to the remote program, which pauses its animations and redraws — saving battery Input (iPhone & iPad) • Sticky Alt on the shortcut bar: word-wise cursor movement (Alt+B / Alt+F) and the last argument of the previous command (Alt+.) now work • New ⌥↩ key for newlines inside command-line programs that take multi-line input • New \ key Also • Sync and pairing codes now draw from the system cryptographic random source, and no longer continue silently if it is unavailable • Fixed monitoring failing on servers reporting unusual disk sizes Questions or ideas are always welcome!

A round of stability and polish fixes. Keys & credentials • RSA private key import completed: classic PKCS#1 supported, public keys derived from the private key for real • Private keys are now always stored as OpenSSH PEM, fixing binary keys being corrupted by sync • New "re-push credentials to iCloud Keychain" in Settings, for when another device is missing them • Credentials carried over from older versions are normalised automatically — nothing for you to do Terminal • Fixed terminals filling only a corner of the window after reconnecting (vim, htop and other full-screen programs) • iPhone & iPad: you can now scroll back through history during continuous output such as tail -f • Steadier Mosh-compatible connections: fixed stalls caused by out-of-order packets being discarded as replays, and spurious "link interrupted" warnings on a perfectly healthy link • Mosh-compatible sessions keep no scrollback (a protocol limitation) — the first time you scroll up we explain why and what to use instead AI agent • Replies render as Markdown instead of showing raw ** and backticks • Approval cards stay fully readable: long commands and rationales scroll inside the card, and destructive commands get a "view full command" link — no more approving what you couldn't finish reading • Adding a follow-up task in the same conversation now regenerates the plan iPhone UI • The terminal's top bar now follows your terminal theme's light/dark, with the status bar and keyboard matching • SSH / Mosh-compatible badges on tabs are far easier to read Sync • Fixed duplicate host rows reappearing after being removed, via iCloud Keep the feedback coming!

Shellby 1.1.0 is our biggest update yet. Mosh-compatible connections • New Mosh-compatible transport: switch from Wi-Fi to 5G, ride an elevator, go through a tunnel — your session stays alive and picks up where it left off • Typing stays smooth even on slow, high-latency links • No mosh-server on the box? The connection test detects it and offers install instructions for your distro Third-party sync — your data, your storage • Sync hosts, keys, snippets, AI settings and chats across devices via your own WebDAV or S3-compatible storage — your data never touches anyone else's server • Effortless pairing: scan a QR code or pick an image on iPhone, import the image on Mac • Sync is now a top-level settings section — manage iCloud and third-party sync in one place Refreshed navigation & UI • Brand-new three-column layout on Mac and iPad • Native tab bar on iPhone; session cards show a live terminal preview • Files, monitor and AI now slide in from the right inside a session • Mac gains a full native menu bar, keyboard shortcuts and window toolbar Snippets & terminal • New command toolbar above the terminal: run, insert or copy your snippets in one tap • Snippet library redesigned: shell syntax highlighting, line numbers, review before you run • Tunnels can now be edited and deleted; ⌘K clears the terminal locally SFTP • Downloads join the transfer queue with a choice of destination; more reliable resume • Drag & drop upload on Mac; system notification when background transfers finish AI agent (bring your own key) • Custom command allow/deny lists; approve & allowlist in one tap • sudo password prompts supported; the agent suspends on disconnect and resumes when you're back online Plus plenty of stability fixes: a rare crash, a keychain edge case that could lose saved passwords, iCloud sync being silently switched off — and a strong warning when a host's key fingerprint changes. Keep the feedback coming!

Every improvement in this update comes from feedback by @break on V2EX — thank you: • AI panel: message text is now selectable, with a one-tap copy button on every reply • AI panel: command output is shown in full, no more truncation • AI panel: resizable width (drag the panel's left edge on Mac, the divider on iPad) • New "Copy on Select" for the terminal: selected text goes straight to the clipboard, just like iTerm (Mac, Settings ▸ Terminal) • File-write diff previews can now expand to show all changes • Fixed: the host-fingerprint prompt could appear behind the New Host form or the Tunnels panel Also in this update: • iPhone & iPad: fixed the garbled display when searching and scrolling in vim and other full-screen programs • Mac: hold a letter key to repeat it — press-and-hold now scrolls continuously in vim, less and friends • Sturdier AI agent, SSH and terminal sessions, with fewer hiccups on flaky connections • Refreshed Mac app icon, localization and polish throughout Keep the feedback coming!
