What's new

Every SigilTTY release, newest first.

1.5

August 19, 2026

  • File preview in the SFTP browser: code with syntax highlighting, images, PDFs and Office documents with Quick Look — over its own connection, so transfers are never held up.
  • The file browser opened from an attached agent session now starts in the agent’s working directory.

1.4.1

August 17, 2026

  • The interface is now available in Simplified Chinese, with an in-app language setting.
  • Paste and drag-and-drop upload now accepts any file — up to 10 at a time — and drag-and-drop arrives on iPad.
  • Voice dictation arrives on Mac.
  • Serial connections gain line-ending and control-line options (Enter Sends, Local Echo, DTR/RTS) on Mac.

1.4

August 16, 2026

  • Voice dictation in agent sessions, bring-your-own-key: OpenAI-compatible endpoints, Volcengine (Doubao) and iFlytek.
  • Agent status everywhere: notifications when an agent blocks or finishes, badges on tabs, and an Agents list on iPhone, in the sidebar and on the Welcome screen — synced across devices.
  • Offline push: end-to-end encrypted agent alerts that reach your iPhone even while SigilTTY is closed.
  • Paste an image into the terminal and its remote path is typed for you — made for remote AI CLIs.
  • The Live Activity now surfaces agent events with a persistent Dynamic Island marker.

1.3

August 14, 2026

  • Attach to the AI coding agents herdr manages on your servers — every agent listed with live status, one tap to attach as a regular terminal tab. Requires herdr 0.8.0 or later.

1.2

August 1–10, 2026

  • Hardware security key (FIDO) sign-in — the private key never exists in software.
  • Live Activity on the Lock Screen and Dynamic Island for active connections (iPhone and iPad).
  • ZMODEM transfers: run sz or rz on the remote side, right in the terminal.
  • Log Center: structured connection logs that stay on your device, with redacted export.
  • A full set of Mac menu commands and shortcuts, a Welcome tab on ⌘N, and Quick Connect on ⇧⌘K.
  • Known Hosts: host trust is now one shared list, manageable in Settings.
  • The shell locale is sent on connect, so non-ASCII filenames survive the trip.

1.1

July 27, 2026

  • Refinements across SFTP, credential handling and terminal output fidelity.

1.0

July 21, 2026

  • Initial release on Mac, iPhone and iPad: SSH, Telnet and the serial console on Mac; SFTP; port forwarding; snippets; Quick Connect; Keychain-backed keys with biometric protection; Key Handoff; themes and CJK fonts; iCloud sync.

Put it on every device you own.
