September 17, 2026 at 6:05 AM UTC

Patch release 3.21.9 (from 3.21.4) on the latest track: team project settings APIs, agent/IDE unification and sidebar defaults, and agent prompt updates.

Changelog

  • [new] Team project settings support via GetTeamProjectsSettings and UpdateTeamProjectsSettings, so team-level project configuration can be read and updated from the product.
  • [new] cursor.agentIdeUnification.enabled — setting/flag to control agent–IDE unification behavior.
  • [new] cursor.defaultSidebarLocation — setting to choose the default sidebar location.
  • [changed] Agent system prompts refreshed (including Composer and persona-powered assistant copy) for how the coding agent is instructed in chat/pair-programming flows.

Availability

3.21.9 is on latest for all desktop targets: macOS (arm64 and x64), Linux (arm64 and x64), and Windows (arm64 and x64). Stable remains on 3.20.21.
