Google today updated its CardDAV API, a protocol for sharing address books and contacts on a server. Developers who sync with Google Contacts will enjoy the additions.

Here are the four new features rolling out today:

  • High resolution contact photos, which enables syncing of full-screen photos used by some mobile devices including iPhones (previously we supported 96×96 thumbnails).
  • Sync-Collections, which improves battery life for mobile users by reducing the amount of data exchanged.
  • POST support, which reduces mobile data usage when creating new contacts.
  • For Google Apps users, searching the domain’s Global Address List.

This is the first major update to the CardDav API. Google launched it in June 2013 when it reversed a decision to kill off its CalDAV API.
