Kiro CLI — November 2026 Releases
5 releases in November 2026.
What's new in Kiro CLI, November 2026
Kiro CLI makes the V3 harness the default and ships as a single kiro-cli binary
Kiro CLI's biggest change so far in November 2026 is that V3 is now the default agent harness for interactive sessions on hosts that can run it. Three releases have shipped so far, from v3.0.0 to v3.2.0, and the month is still in progress.
Existing V2 users are asked before the default applies, and custom agents still in the V2 format are upgraded unless you turn that off. Kiro CLI is now a single standalone kiro-cli binary, which retires the Classic interface, the desktop app, and inline autocomplete. v3.1.0 added PreCompact and PostCompact Hooks and showed session credits in /usage, the status line, and workflow step rows. v3.2.0 added a full-screen Mermaid viewer, sign-in to more MCP servers without OAuth configuration, and a way to run one more iteration on a workflow loop that used all its iterations. Both releases also fixed a range of rendering, workflow, sub-agent, and session issues.
