Agent Instruction History, Browser Notifications, and Claude Haiku 5.5
#Experiment with agent instructions, without losing what worked
Your agents now keep a history of their saved instructions. Open View history from an agent's menu to see previous versions, who saved them, and when. Preview an earlier version and restore it when you want to return to a setup that worked well.
#Stay in the loop from your browser
Notifications are no longer desktop-app only. Enable browser notifications in Settings > Notifications to hear when an agent needs your approval, a pull request opens, or a review is requested. Allow notifications for Tembo in a supported browser, choose which alerts you want, and click an alert to jump back to the work.
#Claude Haiku 5.5 is here
Claude Haiku 5.5 is now available in the model selector for compatible agent runtimes. Choose it when starting a session to try the newest Haiku model on your next piece of work.
#Keep merge request follow-ups in one conversation
GitLab merge request opened and updated triggers now keep the same agent's work in one session. Follow-up updates continue with the existing context rather than starting a fresh conversation. GitHub's ready-for-review trigger also continues the agent's existing session when a draft pull request is ready for review.
#More control over your agents and integrations
- Cursor sessions now support steering while the agent is working, so you can send new direction without stopping the current turn.
- Jira label-added triggers can now be filtered by project and team, so your agents respond only to the issues that matter to them.
- Usage history now shows the model used for each session and lets you search by model name, making it easier to understand your usage.
- Vercel and Cloudflare are now suggested MCP servers. Find them in the integration picker to connect your agents to your deployment and infrastructure tools.
Also various bug fixes and improvements as always :)
