Kiro

This version lets third-party extensions work alongside Kiro, adds support for the latest MCP protocol revision with more reliable sign-in, reduces extension host crashes during large agent responses, and keeps agent turns going when the network briefly drops.

This release gives V3 spec runs a full-screen task execution view with real-time progress and task scope selection. The new Preserve scrollback toggle keeps terminal history available through overflow and resize redraws.

This release brings mouse support to the spec review screen. Under the hood, a stream idle watchdog, automatic retries with backoff, and a 60-minute streaming timeout mean a dropped connection or a throttled request no longer hangs or ends your turn.

This version keeps ignored files out of search results, improves filesystem and command permission rules, and runs agent commands in your configured terminal profile on Windows.

Your team can now access Kiro Web through the Okta or Microsoft Entra ID integration you already use. After an administrator configures access, users only need to sign in. This capability is available with Kiro Pro and above subscriptions.

Add AGENTS.md files throughout your workspace to give Kiro instructions scoped to each directory tree. This version also lowers idle resource use, preserves more context in long sessions, and improves Cloud configuration, chat, hooks, and MCP connections.

This release lets you talk to Kiro instead of typing: /voice dictates your prompts with on-device transcription. Spec runs gain a review screen for reading phase documents and staging line comments, and AGENTS.md files now load as steering context from anywhere in your workspace tree. Enterprise administrators should note that cloud sessions are now opt-in, so organizations that never set the toggle will find them disabled.

This release introduces cloud sessions in preview: run your session in a managed cloud sandbox with --cloud, disconnect while the agent keeps working, and resume from any machine. The slash command menu also gains substring matching, and typing in the TUI stays smoother during rapid input.

This version brings Cloud Sessions to Agent Focus Mode as a preview and gives the sessions rail a collapsible icon-only view, attention cards you can answer in place, and back/forward navigation. It also pins the agent's Windows terminal to PowerShell, restores Always Allow for commands it was quietly forgetting, and fixes the macOS updater downloading every update twice.

This version supports Powers packaged in the open Agent Plugin format and reworks the Agent Focus Mode session rail with pinning, Kiro CLI hand-off, and in-app updates. It also moves Kiro to Code OSS v1.109.5, improves how spec hovers and MCP installs handle untrusted workspace content, and adds bulk session migration and steadier error recovery.
