thread0 0.1.370

Windows and macOS (Apple Silicon) ship the same version.

This release lets one approval cover all your PCs, keeps the phone connected through poor coverage, stops Claude accounts from signing out in the middle of a session, and adds a light theme and larger text. You can share answers out of thread0 and send things into it, name your PCs, and comment on results more easily.

Changes

Your PCs and phones

• Approve a phone once. A phone or browser you approve on one of your PCs is accepted by every PC in your thread0 account. Before, every PC asked for its own confirmation code.
• Add a PC to your account once. The first PC joins on its own. Add another PC from Settings → Connected devices → Add to account by typing the 6-digit code it shows into a PC that is already in the account.
• Name your PCs. Rename a PC in Settings → Connected devices; the name appears on every PC and phone, with the computer name underneath.
• Each account can register 4 phones or browsers and 4 PCs. When a new one goes over the limit, the one unused the longest is replaced. A removed device can register again.
• If your PC list ever shows a PC you don't recognize, you can reset the list from an email confirmation link.

Phone (thread0 Remote)

• iPhone connects on the first try instead of failing first and connecting about 30 seconds later.
• After moving through poor coverage, the phone reconnects on its own — no need to close and reopen the app — and is no longer cut off seconds after connecting.
• "Connected" with every request timing out on a slow link is fixed.
• Save diagnostics saves one file on the device you pressed it on, with this device's records and the connected PC's records in separate sections. Records survive closing the app, and the button is also on the stuck connection screen.
• While the PC cannot check the phone's registration (for example, the service is briefly unreachable), the phone says so and connects as soon as the check succeeds.

Claude

• A Claude account no longer signs out in the middle of a session. thread0 used to close Claude's helper process while it was refreshing its sign-in, which lost the new sign-in.
• Signing out is only confirmed after a second check, for Claude, GPT and Gemini, so a brief hiccup is no longer shown as "signed out".
• An account that needs to review Claude's updated terms says Review terms instead of "signed out", with a button that opens the terms.
• Thinking summaries are shown again. Empty thinking boxes no longer look like they can be opened.
• A failed turn shows one error card in your language, with the service's own message under Show original error.

Comments

• On the phone, the comment box sits right above the keyboard instead of floating over the content.
• Select text while viewing a Markdown or text result and press Comment to comment on it right away.
• Text you type in the message box while you have comments is sent along with them as your overall comment.
• Comment windows look and work the same everywhere, with Cancel and Save.

Display

• Light theme (warm beige), dark theme, or follow the system — in Settings → Display on the PC and the phone.
• Text size 100%, 115% or 130%. On the PC, Ctrl + / Ctrl − (⌘ on Mac) also work.
• Windows uses the Pretendard font for clearer Korean and Latin text.

Sharing

• Share on an AI answer opens your system's share sheet (or copies the text).
• Send text, links or files to thread0 from another app — the phone's share sheet, or Send to in Windows Explorer — and pick the session; they are added to your draft, not sent.

Results

• HTML results on the phone are viewed the same way as when editing: screens drawn by the PC, with next/previous. Slides show only the current screen number.

Security mode

• In security turns, Auto judges the command the AI actually wrote, so switching from Plan to Auto no longer asks about every command.
• After you approve a plan, the permission chip follows the mode the AI moved to.
• Security checks you turned off stay off after restarting.

Local AI

• The built-in runner picks context size, memory and cache settings for this computer, and shows the expected memory use.
• The built-in llama.cpp runtime updates itself after testing the new version, and rolls back if it fails.
• Sessions no longer fail on every turn because of tool definitions the local server could not read.

Other fixes

• The session header labels the context chip and the usage-limit chip, so context use is not mistaken for your plan limit.
• The phone no longer flashes "Can't connect to the PC" on every launch before a PC is saved.
