## Overview

Recently shipped Message-ID inclusion in all webhooks and email endpoints for threading, plus an emoji picker and suppression list management in the Node SDK.

**All email webhooks and GET endpoints now include `message_id` for threading.** Pass it as `In-Reply-To` and `References` on your next send so Gmail, Outlook, and Apple Mail group replies into the same conversation. Reply matching and cross-system correlation follow naturally.

**The MCP server gained idempotency support and domain claim tools.** The hosted remote MCP server (with OAuth) now supports `idempotencyKey` on `send-email` and `send-batch-emails`, surfaces `message_id` in email tool outputs, and accepts a display-name `From` header. Tools for claiming domains and configurable API/host/allowedHosts settings shipped in recent versions.

**React Email’s preview toolbar now has a Props tab for live-editing template props.** Edits re-render the preview without changing `PreviewProps`; invalid JSON is flagged inline. The `email build` command accepts a custom export extension (`--extension .blade.php`). Per-module build output with `sideEffects: false` lets bundlers tree-shake unused components — importing a component no longer pulls in `prismjs`, `marked`, or `tailwindcss` unless actually used. The preview toolbar is now responsive across desktop and mobile. Editor bug fixes include applying inline styles stored on the `code` mark and skipping filler paragraphs when composing emails.

**Node SDK v6.18.0-canary.0 added `resend.suppressions`** with `add`, `get`, `list`, `remove`, and batch `add`/`remove` methods for managing suppression list entries.

The Auth0 provider integration, bar/line/area chart component, AI @-mention context injection, Logs API, Python async support, and the Claude Code plugin remain active and stable.
