Google reverses course, makes CalDAV and CardDAV APIs open to all developers

Google CalDAV and CardDAV APIs now open for all developers

Though Google chucked open API access to CalDAV back in March, it appears the company's had a change of heart. Up until today, only a select few whitelisted developers could make use of Google's calendar open standard; a decision it made based on actual usage data. But given the amount of feedback it's received from blocked devs in the time since, Google's decided to re-instate access to CalDAV APIs, in addition to those for CardDAV -- a first -- its open standard for contacts. The news won't make much difference for Windows Phone 8 users (CalDAV and CardDAV support was already promised), but at least your third-party apps can now continue to play nice with your social calendar.
