ShellFish has supported YubiKeys over NFC for a while, and now USB keys work too. Generate, export, and import them like any other keys - they just require the physical key to authenticate. Due to sandboxing restrictions, USB YubiKeys are accessed from a browser context, so your server needs to support webauthn-sk-ecdsa and the key application field must be localhost rather than ssh: The context menu when starting terminals from the server list now has a submenu for picking an existing tmux session or creating a new one, instead of always connecting to the default. Hover the pointer over the session picker for a thumbnail popup.

Shift + Return works like Alt + Return to add newline without submitting prompt in Claude Code. Control+Backspace will send ascii 8. Improvements to Multipath TCP network mode.

Support for post-quantum key exchange algorithms: mlkem768x25519-sha256, mlkem768nistp256-sha256, mlkem1024nistp384-sha384.

'notify' and 'widget' commands support image payloads also delivered from shell to app using end-to-end encryption. Update Shell Integration scripts and run the commands without arguments for instructions. Accept OSC 52 sequences with empty target for copying to clipboard. Fixed issue where terminal would sometimes lose rightmost characters when resizing window.

Configure whether to use CoreFoundation, plain BSD or Multipath TCP for connections inside Settings > Advanced. Fix to allow copying public key to clipboard directly from SSH key list.

Last update had improvements to handling of .ts.net hostnames allowing the Tailscale on-demand VPN time to start, but would also sometimes introduce a delay for .ts.net hostname if the VPN was already started. This has been improved to avoid delays. New setting to allow manual certificate import on SSH keys which was removed when I added support for CAs. This is accessible from the gear menu when adding a new Certificate Authority and enabled by default if the app detects previous manual certificates.

Improved handling of .ts.net hostnames for better compatibility with Tailscale VPN. This is especially useful with multi-address hostnames like MyMac.local, my-mac.tail2faa9.ts.net which first attempts a local network connection before falling back to Tailscale. Running servers listed for Digital Ocean or Hetzner have button to start terminal whether or not a ShellFish configuration exists for each server. Fixed issue where control sequences like ^X in snippets would be confused with literal caret followed by a letter.

Support for synchronized terminal output mode where server can ask for terminal updates to be deferred until all updates have been sent. This makes Claude Code updates nicer. Certificate Authority feature uses in-app browser for authentication such that no browser tab is left open. Error message is shown when Hetzner API key is wrong during Sign In. Fix issue where terminal word wrap was disabled when restore-cursor sequence was used before save-cursor which would often happen for Claude Code.

Improve Certificate Authority with keyId/principals in signing request and PKCE for OAuth. Fix Unicode variation selectors taking up terminal cell width causing weirdly wrapped terminal lines.

Help page now mentions Hetzner alongside Digital Ocean as a supported provider

Uploads and downloads are allowed to use additional memory and CPU to increase transfer speeds on fast networks.

Hetzner servers can be created and managed from Cloud Servers screen. Drag enbries in server list to customize their order instead of the default alphabetical sorting. Previously, drag and drop could only move servers between groups. Initial support for short-lived SSH certificates generated on-demand by a Certificate Authority with authentication through OpenID. Configure your CA from the key-plus button above the list of SSH Keys, enter the URL + root certificate fingerprint and authenticate through the browser. You will then able to pick this CA instead of a SSH key when configuring the server and during authentication your existing unexpired certificate will be used or a new one will be issued and used requiring you to repeat browser-based approval. This browser-based approval isn't possible for connections coming from Finder that will fail if the current certificate has expired. Includes changes from 2025.36 When approving the use of agent keys, you can configure the approval to last 5 minutes, 60 minutes, or while the connection is active. Import of servers from CSV files started from the + button above the server list has been improved. When the ID field is assigned, existing servers are matched and updated rather than duplicated. A confirmation screen shows which servers will be added, updated, or left unchanged, along with which fields will change. There's a toggle to delete previously imported servers missing from the import file. CSV server import has a field for public key, which can contain either the name of the public key, the full public key with or without comment, or the SHA256 fingerprint. Improvements to terminal when using emoji and side-by-side sessions in tmux.

Improvements to terminal when using emoji and side-by-side sessions in tmux. Includes changes from 2025.29 Use the microphone button in the tab bar for dictation on macOS 26. Speak naturally while transcriptions are displayed and select the transcribed text once you're satisfied with the result. Dictation language is configured in Settings or by clicking gear button in dictation popup. When using a new language for the first time, you may need to wait briefly for the language model to download, as all transcription occurs on-device. This feature works best for natural language when editing in Emacs/Vim or composing instructions for Claude Code, and is less suited for issuing shell commands.
