v 0.1.48

Latest

This release introduces Widgets in Business Mode, improves Remote Access, fixes GPT-5.5 Instant routing, and removes Voice Mode from Proton.

New

  • Added Widgets as a new Business Mode feature, including the Widgets panel, standalone widget windows, embedded widget previews, and widget actions.

Fixed

  • Fixed Remote Access issues, including chat startup reliability, mobile composer spacing, sidebar scrolling, and live syncing of chat deletions and model picker changes back to the desktop app.
  • Fixed GPT-5.5 Instant routing so it works correctly through the ChatGPT subscription path instead of falling through to API-key-only handling.

Removed

  • Removed Voice Mode from Proton.

v 0.1.44

This release makes Flow remote access more reliable on web and mobile, improves mobile Flow Graph navigation, and adds Claude Fable support across Proton.

New

  • Added Claude Fable support throughout Proton, including chat model selection, Flow AI model selection, Mission Control labels, slash-command aliases, token handling, and context-window settings.

Improved

  • Improved the remote-access Flow Graph on mobile with pinch-to-zoom, centered zoom controls, viewport fitting, pan clamping, and double-tap reset, making larger Flows easier to inspect from a phone.

Fixed

  • Fixed Flow remote access so Flows now load, update live, and can be controlled correctly from the web and mobile interface, including run, pause, resume, cancel, debug, and history actions.
  • Fixed the Flow Graph layout in remote access so graph controls and the canvas stay inside the mobile detail view instead of overflowing on narrow screens.

v 0.1.43

This release adds Flows and updates Claude Opus to 4.8.

New

  • Added Flows.

Updated

  • Updated Claude Opus from 4.7 to 4.8.

v 0.1.40

This release adds the first Flow runtime and Flows dashboard, improves Signal visibility, and makes Mission Control threads easier to follow.

New

  • Added the first real Flow runtime, starting with a Numbers Flow that watches a folder, extracts numbers, and cleans up processed files.
  • Added the first Flows dashboard in Business Mode, with a two-pane list and detail shell for future persistent workflows.
  • Signals can now run silently for background checks that do not need to post a chat notification every time.
  • Each Signal now has its own activity log, making recent runs and events easier to inspect.

Improved

  • Improved the Numbers Flow so files with no numbers append 0 instead of producing no output.
  • Improved the Flows detail view with a visual block graph for workflow steps, including branches, actions, and outputs.
  • Flows are now stored as folders with their own flow.json and context.md files, so each Flow can keep dedicated long-term context.
  • Mission Control now shows missions in the order they were created, making mission lists easier to follow chronologically.
  • Removed Atoms and Electrons from the app.

Fixed

  • Fixed Mission Control thread rendering so a mission inside a thread no longer appears again as a separate top-level mission when it starts running.

v 0.1.39

This release upgrades Mission Control with mission threads, selected Skills, model selection, cleaner completion updates, and more reliable recovery after restarts.

New

  • Added mission threads: Proton can now create a named thread of missions that run one after another, where each mission waits for the previous one to finish.
  • Follow-up missions can now receive results from earlier missions as context, making larger multi-step workflows easier to manage.
  • Missions can now use selected Proton Skills during execution.
  • Missions can now run with a selected model and show which model was used.

Improved

  • Mission threads now have a cleaner expandable timeline UI with polished connectors, animations, and consistent card styling.
  • Background mission completion messages are now shorter, cleaner, and deduplicated across restarts.
  • Mission Control can now recover interrupted missions after Proton restarts.

Fixed

  • Fixed project mission controls so stale or wrong-scope mission IDs no longer break chat or Telegram.
  • Fixed conversation compaction so GPT-selected compaction now uses GPT for the full compaction workflow instead of silently using Claude for part of it.

v 0.1.38

This release introduces Mission Control, a new way to send Proton on background missions while you continue chatting, with real-time progress and inspectable actions.

New

  • Added Mission Control: Proton can now run long background missions while you keep using chat.
  • Mission progress, plans, logs, files, and actions are visible in a dedicated Mission Control interface.

Fixed

  • Claude connection reliability fixes so Claude models work correctly again.

Improved

  • Redesigned the chat Project Tab and Projects view to support the new Mission Control workflow.
  • Files opened from Proton’s file manager now open externally in the system app instead of inside Proton.
  • Made project list items taller so longer project names can wrap cleanly across two lines.
  • Update notifications now include a link to see what changed in the new version.
  • GPT-5.5 reasoning now shows “None” instead of “Auto” when no reasoning effort is selected.

v 0.1.37

A design polish release that redesigned the dashboard views to make Proton feel much more consistent across the desktop app.

Improved

  • Redesigned Schedule, Signals, Activity, Memory, Skills, Tools, Images, Sandbox, Atoms, and Projects.
