36Kr AI reported that Anthropic released a major update to the Claude Code desktop app that can launch multiple conversations in parallel and return their results to the main session. The report says the new version automatically creates nested sessions for subtasks it judges can run in parallel, and redesigns session management with saved environments, per-folder Git Worktree isolation, a /btw command for side questions in a separate tab, and idle context compaction. An Anthropic engineer, Thariq, is quoted as calling it “almost a v2 version”; the feature details and that characterization come from a single Chinese report and have not been independently confirmed.
