- Improved retrieval of tmux session lists when connecting via Mosh
- Fixed an issue where tmux session names were not recognized correctly in some Mac environments, preventing connections to existing sessions
- Improved handling of cases where tmux session names contain underscores

・Improved diagnostics when checking tmux sessions during Mosh-preferred connections.
・tmux session discovery now preserves details for cases such as missing tmux, command failures, and socket mismatches.
・Improved handling of early Mosh connection failures so the connection screen no longer closes without showing the reason.
・When no tmux sessions are found normally, the app now continues to the shell without interrupting the connection flow.

Improved Mosh connection status visibility and SSH key management.

- Mosh connection progress now shows clearer steps, including SSH authentication, tmux checks, mosh-server startup, Mosh connection startup, and waiting for the server response.
- Added clearer guidance when deleting SSH keys, making it easier to understand the difference between removing a key from MT and removing a public key from the server.
- Improved biometric authentication prompts so it is clearer why an SSH private key is being accessed.
- Fixed minor issues around connection handling and SSH key management.

Fixed issues related to saving and displaying SSH keys.

Fixed a case where generated or imported SSH keys might not appear in the key list
Improved SSH key selection after saving a new key
Improved server-side public key registration and removal flows
Added a confirmation step before removing a public key from a server
Improved error messages for Keychain-related failures

Improved Mosh connection reliability. This update fixes an issue where Mosh sessions could remain blank or unresponsive on local network or VPN/Tailscale connections, and improves error reporting for hostname and IPv6 resolution failures.

This release also improves connection diagnostics, Low Data Mode and expensive network indicators, and compatibility with iOS 18 and later.

• Fixed a rare "endless Face ID prompt" loop that could appear on app launch or after enabling biometric protection on an SSH key — a workaround for an iOS 26 Keychain enumeration change.
• Biometric-protected keys now show the correct Face ID / Touch ID / Optic ID label on each device.
• You can now turn biometric protection on or off for an existing SSH key without deleting and re-adding it.
• Face ID / Touch ID prompts now appear only when MT actually needs the key — not at launch, when editing a connection, or when opening Security settings.
• Successful biometric auths are reused for up to 5 minutes, so reconnects within that window stay silent.
• Assorted stability improvements around credential and iCloud sync.

v1.2.1 — Claude Code companion features are now officially supported.

• Tap a notification to auto-resume the exact tmux session over Mosh
• Premium plan rebranded to "MT Pro" — same features and price
• Refined in-app review prompt timing
• Stability improvements and bug fixes
