Changelog
What shipped. Every week, in plain words.
New features and improvements across ReasonOS, newest first.
September 2026
- QA
Every click drawn on the page, and a design reviewer on every screen
Open any step of a QA run to see exactly where the agent clicked, drawn on the page it clicked, with a crop of the element beside each action. A design reviewer looks at every screen the run visits and flags what a top-tier team would not ship — misrendered or misaligned elements, confusing flows, sloppy copy — as findings beside the step, numbered on the page. Requests open to their headers, bodies and timing, and each step keeps its console, its document and the browser’s load.

AI orchestration for role-based agent teams
Set up Design, Risk Assessment, Impact Analysis, Code, Test Generation, Code Review and AI Test & Iteration roles. Assign primary agents and independent reviewers, keep people at decision gates, preserve workflow evidence, and compare recorded outcomes.
Learn more → - QA
A step-by-step view of every QA run
Open any run to see each step’s outcome, its retries and which steps were reused from a previous run. Repeat runs of the same test now behave the same way.
Learn more → - Agents
Claude Code, Codex and Gemini in the editor
Chat with Claude Code, Codex or Gemini inside a branch, approve their actions as they work, and set a default agent for each project.
Learn more → - QA
A guided start for QA
A setup guide, a test picker and a live replay make it quicker to write your first tests and watch them run.
Learn more → - Agents
Bring your own AI subscription
Link your own Claude, ChatGPT or Google account, or give a project its own API keys, so agents run on the plan you already pay for. Keys are encrypted and never reach a branch.
Learn more → - Platform
Email notifications
Hear when a CI run finishes, a review or merge happens, a QA suite settles, someone mentions or assigns you, or opens a document you shared. Choose what you get in Settings.
- Documents
Page previews for documents
Uploaded decks and documents now render page by page, so readers never need to download a file.
Learn more → - Documents
Document library, share links and data rooms
Keep a shared library, send a link per recipient, build data rooms, and give people access to documents without access to code.
Learn more → - Platform
Guided tours inside the product
Built-in walkthroughs cover the platform, stacked changes, working together in a branch and reliable builds.
- Build
Bring a repository, build it with no setup
Import an existing repository and run, build and test it without writing any build files first.
Learn more → - Security
Required two-factor sign-in
Organizations now require an authenticator app by default, and admins can cap how long a branch’s credentials last.
- Security
Workspace activity log
Owners and admins can browse and filter every sign-in, push, merge, permission change and secret change in one log.
August 2026
- Build
A shared build cache
Builds reuse results a teammate, an agent or CI already produced, and each project shows how much the cache saved.
Learn more → - QA
Agentic QA
Write tests as plain sentences. An agent runs them in a real browser with recordings, screenshots of every step, test personas and saved sign-in states.
Learn more → - Planning
Issues, cycles and initiatives
Plan work next to the code: issues link to their branch and review, cycles track progress, and initiatives group the bigger bets.
Learn more → - Build
Ask your codebase a question
A map of your code, built without sending it to a model: ask where something happens, see who calls it and what a change would touch.
Learn more → - Security
Custom roles, teams and managed secrets
Write roles from allow and deny rules, grant them to nested teams, and keep secrets encrypted and scoped to a project or an environment.
- Review
Branch rules with required checks
Protect branches: require reviews, passing CI and QA checks, linear history or signed commits before anything merges.
Learn more → - Review
Stacked reviews
Split a large change into small ones that are reviewed separately and land in order.
