Cosmos Week 37 Release Notes

Control which models your team can use

Admins can now choose which models people in their organization can use. Set a default on the new Model Access page and override it for individual models. Fleet Management flags Experts that use a model your organization no longer allows.

New features

  • Admins can manage every secret in the organization from Secrets, including its owner and the Spaces that can use it, and delete secrets they no longer need.
  • Admins can create user groups and assign them to resources to manage access.
  • Browser push notifications for agent updates are available in beta. Turn them on in Settings.

Improvements

  • Sessions can clone repositories from more than one GitHub organization.
  • Incident Investigator can investigate incidents you describe directly in Cosmos, not only from alert threads.
  • Agents can create private Slack channels and start group DMs. A Slack workspace admin needs to reconnect Slack in Settings > Connectors to turn this on.
  • Runlayer is now in the MCP catalog.
  • You can filter connectors that need attention, and MCP errors explain how to fix them.
  • Environments can repair their repositories, and failed refreshes tell you what to do next.
  • Sessions stay active while you use a tunnel.
  • Session snapshots are now kept for 14 days.

Bug fixes

  • You can save changes to a shared Expert, and saving an Expert no longer changes its hidden triggers.
  • Organization members can edit organization files.
  • Notifications you've read are now marked as read in all your open tabs.
  • File previews update when someone else edits the file.
  • Logging out returns you to Cosmos.
  • Fixed the Settings menu shortcut and added compatibility for Dvorak keyboards.
  • DevRev webhooks no longer fail signature checks.
