Shipped August 12 on the Agent Host Protocol: the same agent session attaches from multiple VS Code windows, and the model picker exposes both Anthropic and Copilot options, switchable between turns and billed to the respective service.

HTML files in the integrated browser auto-reload on edit. VS Code

Released August 26, the Agents window defaults to a single-pane side layout with session state surfaced as pills above the chat input showing changes, pull requests and artifacts. It now lists recent Copilot or Claude sessions started in other applications, two by default, tun...
The New Stack's coverage of Cursor 3 leads with a provocative framing: the IDE is now a fallback, not the default. That's deliberately inflammatory. It's also not wrong. Cursor 3 is a full redesign built around an "Agents Window" command hub. The headline feature is multi-agen...
