IDE changelog

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 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.

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 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.

Cloud Sessions are now available in Agent Focus Mode as a preview. Start a session that runs in the cloud alongside your local ones, pick the repositories it works against, and keep those repositories visible below the chat. Cloud sessions use the same agent and model selectors as local sessions. Learn more ->

Collapse the sessions rail to an icon strip to give the chat more room, with every session still one click away. When a session needs your input, an attention card appears next to the chat with the question and the agent's options as buttons, so you can answer it without switching over. The attention panel never opens on its own, and won't raise itself for the session you already have on screen. And you can move back and forward across sessions and settings from the titlebar (Cmd/Ctrl+[ and Cmd/Ctrl+]). Learn more ->

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.

Install powers aligned with the open Agent Plugin format from a local folder or GitHub URL. Kiro now supports plugins that bundle skills and MCP making powers easier to share across compatible agent tools.

Pin a session with Pin Session to keep it at the top of its section. Resume an existing session in Kiro CLI with Open with Kiro CLI. When a new version of Kiro is available, an update row appears in the rail footer, and the settings pane gains a Check for Updates button. Spec documents and task rows in the context panel now open directly in the editor. Learn more ->

This version adds a Kiro submenu to the editor context menu and an Ask Kiro to Fix quick fix on errors and warnings, plus a guided form for creating hooks. Kiro moves to Code OSS v1.108.2, and now replies in your IDE display language. Chat history also survives workspace folder changes, and several sign-in, trust, and approval issues are fixed.

This release adds user-level global hooks, a searchable session history panel, and stronger reliability for corporate proxy environments. The agent now recovers automatically from interrupted responses and refreshes MCP tools dynamically.

Sessions restore automatically on launch, idle resource consumption is lower, prepaid credit packs appear in the account dashboard, and several fixes ensure permissions, hooks, and steering behave correctly across windows and custom agent profiles.
