Kiro 2.26.0

September 30, 2026 Workflows, Classic Migration Guidance, and V3 Approval Safeguards 2.26.0 Run reusable, multi-step Workflows in V3, get clear guidance when Classic sessions start, and use stricter approval checks for files, tools, and shells. Kiro CLI 2.26.0 adds opt-in Workflows for reusable, multi-step tasks and helps Classic users identify what to change before moving to the terminal UI. V3 also tightens approval checks for Hook and Language Server Protocol (LSP) file writes, for MCP tools and shell commands in untrusted workspaces, and for approvals that change while an action waits. Run multi-step Workflows In a V3 session, open /settings , choose Features , and enable Workflows , then restart Kiro CLI to apply the change. Then ask Kiro to create a Workflow from the outcome you want, or launch a recipe with /workflow run , and use the /workflow commands to inspect and manage runs.
