W4, April 22-30, 2026
Introducing workspace agents in ChatGPT—shared agents that can handle complex tasks and long-running workflows across tools and teams. https://t.co/eHplfXCWlk
We’re introducing the Cursor SDK so you can build agents with the same runtime, harness, and models that power Cursor. Run agents from CI/CD pipelines, create automations for end-to-end workflows, or embed agents directly inside your products. https://t.co/bRcn9xjuVz
Introducing /multitask in the new Cursor 3 interface. Cursor can now run async subagents to parallelize your requests instead of adding them to the queue. For already queued messages, you can ask Cursor to multitask on them instead of waiting for the current run to finish. https://t.co/gtvOlup2hX
Introducing Linear Releases. Manage software releases directly from Linear. Track the deployment environment, version, and status of every issue to give team members and agents your full deployment context. https://t.co/HJ9XWHFAi6
