What

Adds the What's New entry for the Week of June 15, 2026 (fern/changelog/2026-06-15.mdx).

This covers what shipped in the weekly release weekly-20260609 → weekly-20260616-hotfix. Because last week's release was rolled back and re-shipped this week, this single entry includes both the re-shipped items and the genuinely new ones.

Entries

1. Claude Haiku (Global) — now available as a model through Amazon Bedrock.
2. Pronunciation Dictionary Management in Voice Config — view/manage API-configured dictionaries in the dashboard; stale references flagged.
3. Rotating Tool Messages — configure multiple tool message variants, picked at random.
4. Dynamic Variables in Test Calls — set variable values before starting a dashboard test call.
5. Concurrency and Rate Limits in Organization Settings — now shown as read-only fields.
6. Fixes and Improvements — squad Cartesia voice overrides, duplicate-tool dedupe at the LLM stream, analytics concurrency chart fix.

Excluded (per the What's New criteria)

• Microsoft AI Voice — gated behind enable-mai-voices, restricted to internal vapi.ai accounts (not GA).
• Composer / Simulations — Alpha features.
• Internal infra (DB cutover, queues/workers, auth migration, CI, typecheck), and very minor UI changes.

Testing

• Verified rendering on the local Fern build server — formatting, nested sub-bullets (🌿 ✨ [Scheduled] Update API Spec #2, chore: update styling #6), and all five docs.vapi.ai links resolve.
• Date confirmed: June 15 is the Monday of the week (filename + title follow the Monday convention).

Notes

• One link to spot-check on the Fern preview deploy: item 3's tool message variants → /tools/custom-tools (best-available anchor).
