Highlights

Single-tool MCP interface — domshell_execute is the primary tool; pass any DOMShell command as a string, or several newline-separated for a workflow in one call. The 38 per-command tools remain available with --granular.
Concurrent multi-agent — multiple MCP clients can connect simultaneously, each in its own isolated 🐚 agent tab group with its own shell state. No more single-session lockout.
Agent-declared sessions — optional group_id parameter on domshell_execute lets an agent address a specific lane ("new" for a fresh one; pass an existing id to join — agent-to-agent handoff). Two chats in one Claude Desktop can each get their own lane despite sharing one MCP connection. Every reply ends with [lane: <id>].
Per-session kernel — each side-panel window and each MCP connection runs in its own session: own current tab, DOM cursor, command history, and tab-group binding.

See CHANGELOG.md for the full list, including the bug fixes and migration notes.
