Changelog and deprecations

Every change to the SDKs, the API, webhooks and the export format. An old API version keeps working for at least 18 months after its replacement ships.

  1. AddedMCP server

    New tool: create_draft_reply

    AI tools can save a draft reply on a conversation. A teammate reviews and sends it. The tool cannot send on its own.

    page and per_page keep working on version 2026-03-01 and earlier until 1 March 2028. Move to cursors: every list response already includes next_cursor.
