What changed

New features

3
  • Choose how terminals behave before installing an update — the Restart & Install screen now includes the experimental terminal keep-alive option and explains exactly what will happen during this restart
  • See whether running terminals will continue through the update or be saved and restored
  • Changes made here stay in sync with Settings → Terminal and take effect at the correct restart

Improvements

6
  • Keep busy terminal workspaces responsive — live run indicators now update only while visible, pause when 1DevTool is in the background, and avoid refreshing every tab when a single AI agent starts or finishes
  • Vertical Tabs shows one stable elapsed timer instead of duplicating it, long timers no longer shift tab content, and reduced-motion preferences are respected
  • Closing a terminal now releases its saved status and timer state instead of leaving it behind for the rest of the app session
  • Keep your reading position when focusing a terminal — clicking an AI terminal no longer pulls its output to the bottom, so you can select, focus, and continue reading older output without losing your place
  • Paste into Agent Input only when you choose — opening the composer no longer reads or fills from the clipboard, and multiline terminal pastes are no longer redirected into it automatically
  • Manual text paste inside Agent Input, terminal-copy line-wrap cleanup, and image attachments continue to work normally

Bug fixes

2
  • Fixed blank terminals when keep-alive was enabled in packaged macOS builds — shells and AI terminals now open correctly when the experimental background terminal service is active
  • If that service cannot start a terminal, 1DevTool automatically falls back to normal session saving and restoration instead of leaving every terminal blank
