https://kiro.dev/changelog/cli/2-19/ Sat, 22 Aug 2026 09:40:12 GMT Kiro adds mouse support to spec review and automatic stream recovery with configurable timeouts. • Adds `api.streamIdleSoftTimeout`, `api.streamIdleHardTimeout`, and `api.timeout` settings to tune idle watchdog thresholds and the overall streaming timeout. • Adds a 60-minute default streaming timeout so long responses are no longer cut off mid-turn. https://kiro.dev/changelog/cli/2-19/ https://kiro.dev/changelog/cli/2-19/ Fri, 21 Aug 2026 09:51:54 GMT Kiro adds spec review mouse support, AI session titles, and automatic stream recovery with idle watchdog and configurable timeouts. • Adds `api.streamIdleSoftTimeout`, `api.streamIdleHardTimeout`, and `api.timeout` config settings to tune the new idle watchdog, automatic retry-with-backoff, and 60-minute streaming timeout for stalled or dropped connections. • Adds AI-generated session titles to the V3 session resume picker, surfaced via `kiro-cli chat --resume-picker` or `/chat resume`, so similar sessions are distinguishable at a glance. • Adds mouse support to the spec review screen — scroll to navigate and click to position the cursor — with `m` toggling mouse support on or off. • Introduces a stream idle watchdog that warns after 60 seconds of silence and cancels at 300 seconds, with automatic retries for throttling, 5xx errors, and connection drops. https://kiro.dev/changelog/web/kiro-web-access-with-okta-and-microsoft-entra-id/ https://kiro.dev/changelog/web/kiro-web-access-with-okta-and-microsoft-entra-id/ Thu, 20 Aug 2026 09:49:19 GMT Kiro Web now supports SSO login via Okta and Microsoft Entra ID using OIDC, with Cloud Sessions available for Pro and above. • Adds SSO access to Kiro Web via Okta and Microsoft Entra ID using OpenID Connect (OIDC), requiring admins to add `https://app.kiro.dev/signin/oauth` as a sign-in redirect URI to an existing Kiro OIDC application. • Introduces Cloud Sessions (Preview), which can be enabled independently from API key generation, available on Kiro Pro and above subscriptions. https://kiro.dev/changelog/ide/1-0-288/ https://kiro.dev/changelog/ide/1-0-288/ Wed, 19 Aug 2026 09:48:53 GMT Kiro gains Agent Plugin format support, session pinning, and Kiro CLI hand-off in Agent Focus Mode. • Adds support for the open Agent Plugin format, letting users install Powers (plugins that bundle skills and MCP servers) from a local folder or a GitHub URL — shareable across compatible agent tools. • Adds `Pin Session` action in Agent Focus Mode to keep a session pinned at the top of its section in the session rail. • Adds `Open with Kiro CLI` action to resume an existing Agent Focus Mode session directly in Kiro CLI. • Adds an update row in the Agent Focus Mode rail footer and a `Check for Updates` button in the settings pane when a new Kiro version is available. • Spec documents and task rows in the context panel now open directly in the editor. • Adds bulk session migration for Agent Focus Mode sessions. https://kiro.dev/changelog/models/claude-opus-5/ https://kiro.dev/changelog/models/claude-opus-5/ Wed, 19 Aug 2026 09:48:53 GMT Claude Opus 5 is now available in Kiro IDE, CLI, and Web with a 1M context window. • Adds Claude Opus 5 to the Kiro IDE, CLI, and Web model selector for Pro, Pro+, Pro Max, and Power customers in us-east-1 and eu-central-1 with cross-region inference. • Claude Opus 5 supports a 1M token context window with a 2.2x credit multiplier. • Claude Opus 5 brings improved multi-agent coordination with fewer conflicts between parallel agents running concurrently. • Claude Opus 5 adds self-verification and iterative refinement on agentic coding tasks, reducing stubs and placeholders in generated output. • Code review with Claude Opus 5 delivers higher real-bug detection rates with lower false positives, including at reduced effort settings. https://kiro.dev/changelog/cli/2-17/ https://kiro.dev/changelog/cli/2-17/ Wed, 19 Aug 2026 09:48:53 GMT Kiro CLI gains cloud sessions (preview) with `--cloud`, `--repo`, and `--resume-id` flags, plus substring matching in the slash command menu. • Adds `--cloud` flag to `kiro-cli` (and `kiro-cli chat --cloud`) to run a session in a managed cloud sandbox instead of locally. • Adds `--repo` flag (and `/repo` picker) to attach repositories to a cloud session. • Adds `--resume-id` flag to reconnect to a cloud session from any machine after disconnecting while the agent continues working. • Cloud and local sessions now appear together in the session picker UI. • IAM Identity Center administrators enable cloud sessions via the 'Cloud Sessions (Preview)' setting (formerly 'Kiro Web (Preview)'). • Slash command menu gains substring matching, making commands reachable without typing a prefix. Breaking changes: • The IAM Identity Center admin setting 'Kiro Web (Preview)' is renamed to 'Cloud Sessions (Preview)'; organizations that had the prior setting remain enabled, but new organizations must explicitly opt in. https://kiro.dev/changelog/ide/1-0-293/ https://kiro.dev/changelog/ide/1-0-293/ Wed, 19 Aug 2026 09:48:53 GMT Kiro adds Cloud Sessions to Agent Focus Mode preview, with collapsible rail, in-place attention cards, and session navigation. • Adds Cloud Sessions to Agent Focus Mode as a preview, letting sessions run in the cloud alongside local ones with selectable repositories kept visible below chat. • Cloud sessions use the same agent and model selectors as local sessions. • Adds a collapsible icon-only view for the sessions rail, keeping every session one click away while giving more room to the chat panel. • Adds in-place attention cards that surface agent questions and action buttons next to the chat without requiring a context switch or raising the attention panel automatically. • Adds back/forward navigation across sessions and settings from the titlebar via `Cmd/Ctrl+[` and `Cmd/Ctrl+]`. • Pins the agent's Windows terminal to PowerShell. https://kiro.dev/changelog/ide/1-0-242/ https://kiro.dev/changelog/ide/1-0-242/ Wed, 19 Aug 2026 09:48:53 GMT Kiro adds an editor context menu submenu, Ask Kiro to Fix quick fixes, guided hook creation, and a Code OSS v1.108.2 upgrade. • Adds a 'Kiro' submenu to the editor context menu for quick access to Kiro actions from within the editor. • Adds an 'Ask Kiro to Fix' quick-fix action on errors and warnings, surfacing AI-assisted remediation inline. • Adds a guided form for creating hooks, replacing the need to author hook configuration manually. • Upgrades the underlying editor to Code OSS v1.108.2. • Kiro now replies in the IDE's configured display language. • Chat history now persists across workspace folder changes. https://kiro.dev/changelog/ide/1-0-309/ https://kiro.dev/changelog/ide/1-0-309/ Wed, 19 Aug 2026 09:48:53 GMT Kiro adds nested AGENTS.md support for directory-scoped agent instructions and improves long-session context retention. • Supports `AGENTS.md` files placed at any level of a workspace directory tree, allowing agent instructions scoped to each subdirectory. • Preserves more context during long sessions, reducing loss of conversation state over extended interactions. • Lowers idle resource consumption during inactive periods. https://kiro.dev/changelog/ide/1-0-337/ https://kiro.dev/changelog/ide/1-0-337/ Wed, 19 Aug 2026 09:48:53 GMT Kiro agent commands now run in your configured terminal profile on Windows, with improved permission rules. • Agent commands now run in the user's configured Windows terminal profile instead of a default shell. • Improves filesystem and command permission rules for agent operations. • Keeps ignored files out of search results. https://kiro.dev/changelog/cli/2-15/ https://kiro.dev/changelog/cli/2-15/ Wed, 19 Aug 2026 09:48:53 GMT Kiro adds a guided description step to `/spec new` and auto-executes approved plans in Plan mode. • Adds a guided description prompt to `/spec new`: the agent now asks what the spec should cover before drafting requirements, using your description as ground truth instead of inferring from the spec name alone. • Plan mode now auto-executes the approved plan immediately after approval, removing the manual mode-switch step. https://kiro.dev/changelog/cli/2-16/ https://kiro.dev/changelog/cli/2-16/ Wed, 19 Aug 2026 09:48:53 GMT Kiro gains `/tangent` side-conversations and per-tool token breakdown in `/context`. • Adds `/tangent <name>` to branch a named side-conversation that inherits the full conversation history, letting you explore freely without polluting the main thread. • Adds `/tangent ls` to browse the full conversation tree in a visual picker. • Adds `/tangent root` to jump straight back to the main conversation from any depth. • Extends `/context` with a per-tool token breakdown so you can see exactly what is consuming your context window. • All `/tangent` features are available in V3 mode via `kiro-cli --v3`. https://kiro.dev/changelog/cli/2-18/ https://kiro.dev/changelog/cli/2-18/ Wed, 19 Aug 2026 09:48:53 GMT Kiro gains `/voice` dictation, spec review with `Ctrl+X`, nested `AGENTS.md` steering, and opt-in cloud sessions. • Adds `/voice` command (also triggered by holding `Space`) to dictate prompts with on-device Whisper transcription — no audio leaves the machine and no cloud API key is required. • Adds `Ctrl+X` at spec phase checkpoints to open a review screen where you can read phase documents and stage line comments, sending all staged comments as one revision request when the checkpoint is answered. • Supports `AGENTS.md` steering files anywhere in the workspace tree (not just the workspace root or `~/.kiro/steering/`), so steering context can live next to the code it describes. • Cloud sessions are now opt-in: administrators must explicitly enable 'Cloud Sessions' in the Kiro console, and an unset toggle now defaults to disabled. Breaking changes: • Cloud sessions default to disabled; organizations that never configured the 'Cloud Sessions' toggle in the Kiro console will find cloud sessions unavailable until an administrator explicitly opts in.
