What changed

Since v1 (12 August 2026).

• addedA section on what the page can hear — tool-started / tool-progress / tool-finished with args, result and citations, plus `thinking`, `agent-partial`, `agent-word` and `listening-started`.When an agent calls a tool it stops talking. Before 0.5.0 an embed went silent for however long the tool took, with no event to hang a UI on — and every caller reads silence as a hang.
• added`sendText()` — type into a live call, or take a turn over HTTP without one.A visitor who cannot speak, or will not in an open-plan office, had no way to use a voice agent at all.
• changedHistory now reads `sessions`, not `calls`.`calls` means “rows from the calls table” and structurally cannot see a text thread. Anyone building a text product was reading a fraction of their own history with no signal the rest existed.
• added`sessions.trace(id)` — which provider and model actually answered a turn, and whether it failed over mid-turn.It is the only view in the product of what really served a conversation, which is the first question when a call goes strange.
• changedErrors are typed and carry a code: 402 out of credit, 403 missing scope (named), 404 not found.The old guidance was one sentence — “check the key and the agent id” — for three unrelated failures with three different fixes.
• fixedThe microphone is checked before connecting, with the fix in the message.A refused microphone used to bring the session up and then ignore the visitor for the entire call.
• fixed`whissle` CLI links point at whissle.ai, not the retired platform.whissle.ai.That host answers 503, and the URL is persisted in ~/.whissle/config.json — so 1.0.2 migrates a stored one rather than only changing the default.

• addedThe first public edition: provision agents from one JSON file, mint a session server-side, run a call with or without an avatar, read transcripts and scores.Everything before this was a private example nobody outside the team could run.
