Start Without a Repo, Switch Modes Anytime

You can now start a Kiro Web session without connecting a GitHub repo first, and switch to Autonomous mode at any point in a Vibe session, not just at the start. This update also brings relative message timestamps, clearer network mode visibility, and a round of sandbox and reliability fixes.

You no longer need to add a GitHub repository to start a session. Open a session, describe your task, and connect a repo later if you need one.

In a Vibe session, you can now select Autonomous mode after your first prompt, not just at session start. Hand off to the agent whenever you're ready without starting over.

Session messages now show relative timestamps. Hover to see the absolute time, making it easier to track when events occurred during long-running tasks.
