Release Notes: What's New

A dated log of new features, improvements, and fixes across the platform, newest first. Check here to see what changed, when it changed, and how it affects the way you build Editions, send Broadcasts, and read your reports.

What this covers

Each release entry is grouped by date and, where useful, labeled by area:

  • New — capabilities added for Authors, admins, analysts, or developers.
  • Improved — refinements to existing features (editor, deliverability, reporting, integrations).
  • Fixed — resolved defects and behavior corrections.
  • Deprecated / Changing — advance notice of features being retired or altered, so you can plan ahead.

Entries note anything that may need action on your side, such as a settings change, a re-authorization, or an updated personalization tag.

Key tasks

  • Scan the latest entry at the top of the sidebar to see what shipped most recently.
  • Filter by what you care about — for example, look for reporting or deliverability changes if that is your role.
  • Watch for action-required notes. Some updates ask an admin to review account settings or reconnect an integration (confirm the exact steps in your account).
  • Share relevant changes with your team, especially developers who rely on the API or SSO.
  • Shiny new help system with details you never saw before.

New releases roll out on a regular cadence. If a change affects data you have already sent, the entry will call that out explicitly.
