npm install lemma-sdk@latest # TypeScript SDKWhat's new in 0.9
- A new workspace. Resources open beside the conversation (or as a sheet on your phone), history is searchable, and a pod shows who has access to it.
- A browser you can watch and take over. The agent's browser streams live: click, type, paste, and sign in to sites right from the conversation.
- Agents that wait, and ask before running on.
wait_forlets an agent wait on a time, a process or a sub-agent without cost, and a very long or failing run pauses to ask. - Approvals run as you. When you approve an agent's action, it runs with your access — for that one action, and nothing more.
- Desktop. Settings live under This Mac, coding agents can be steered while they work, updates download only what changed, and quitting takes seconds.
- Connectors and channels. Attach pod files to any connector, send and draft in Gmail, connect Shopify with OAuth, and WhatsApp conversations keep their full history.
Upgrading from 0.8
A few API responses changed shape, one protocol moved, and approvals now run as the approving person. If you use the API, SDKs or CLI directly, read what changes for API, SDK and CLI users before upgrading.
