<Update label="v2.1.0" description="18 Sept 2026">
  `data-sync`

  Adds DataSync support for user privileges, account emails, tags and custom fields. Tags and custom fields now always request a full page, using the account maximums Constant Contact documents (500 tags, 100 custom fields), so a sync returns the whole collection. Other collections are not synced because Constant Contact returns the paging cursor only inside a link URL, which leaves no way to read past the first page.

<Update label="v2.0.1" description="11 Sept 2026">
  `guide`

  Updated OAuth 2.0 connection guide. It now walks the developer portal screen by screen with screenshots, matches the portal's actual labels, covers the redirect URI and secret confirmation dialogs, and explains which scopes to grant.
</Update>

<Update label="v2.0.0" description="10 Sept 2026">
  `breaking` `bug-fix` `description-fix`

  Breaking — filtering an email bounces report by bounce code now takes several codes as a list rather than a single value. Also corrects input guidance across contacts, contact lists, custom fields, segments, events, campaigns, bulk imports, account emails and reporting so calls succeed on the first attempt.
