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.
