Pull Request Workspace, AI-Generated Tours, and Pinned Sessions

#Reviews is now a complete pull request workspace

The reviews feature flag is gone, so pull request reviews are now on by default for everyone. Reviews grew into a full workspace for getting a PR merged: a dedicated attention indicator in the sidebar surfaces reviews waiting on you, the file tree and diff viewer got a round of polish (file-type icons, cleaner embedded diffs, steadier scrolling), and you can submit a review with Cmd+Enter without leaving the keyboard.

#AI-generated tours for every pull request

Reviews can now generate a guided tour: a walkthrough of a pull request that highlights the key changes and explains why they matter, so reviewers can get oriented before diving into the diff line by line.

#Pin your most important sessions

You can now pin sessions to a dedicated section at the top of the sidebar, so the work you care about most stays one click away instead of scrolling through recent activity to find it.

#Workspace deletion

Org admins can now permanently delete a workspace from settings when it's no longer needed, instead of leaving it around indefinitely.

#New Linear trigger: Issue Updated

The Linear integration now includes an Issue Updated trigger for automations, so you can kick off follow-up work whenever an issue's fields change, not just when it's created.

#More agents: Kimi K3 and the Pi SDK runtime

Kimi K3 is now available as a model option via Fireworks, and the Pi agent now runs on the official Pi SDK runtime for a faster, more reliable hot path.

#Usage, billing, and everyday improvements

  • Billing and usage pages now show dollar amounts instead of credits.
  • A new token usage metric card in Insights → Models makes it easier to see consumption at a glance.
  • The getting started checklist now includes a step for creating your first snapshot.
  • Set a default agent per user from the Preferences tab in settings.
  • The new session dialog has an options menu for configuring a session's setup before you start it.
  • A new Tailscale integration lets you connect agent sandboxes to your Tailscale network with ACL and tag support, available from Settings → Integrations.

Also various bug fixes and improvements as always :)
