Kiro CLI — August 2026 Releases
4 releases in August 2026.
What's new in Kiro CLI, August 2026
Kiro CLI adds cloud sessions, /voice dictation and a spec review screen
Kiro CLI's main additions in August 2026 are cloud sessions in preview, voice input with /voice, and a review screen for spec runs. Four releases shipped, from v2.17.0 to v2.20.0.
Cloud sessions run in a managed cloud sandbox started with --cloud, keep working after you disconnect, and can be resumed from any machine. Enterprise administrators should note that cloud sessions became opt-in in v2.18.0, so organizations that never set the toggle will find them disabled. /voice dictates prompts using on-device transcription. Spec runs gained a review screen for reading phase documents and staging line comments, later with mouse support, and V3 spec runs got a full-screen task execution view with real-time progress and task scope selection. AGENTS.md files now load as steering context from anywhere in the workspace tree. Reliability work in v2.19.0 added a stream idle watchdog, automatic retries with backoff and a 60-minute streaming timeout, so dropped connections or throttled requests no longer hang or end a turn.
