At the end of 2011 we announced the Google Analytics Core Reporting API as a replacement for the Data Export API. We also announced a 6 month deprecation period for the Data Export API version 2.3, after which all v2.3 queries will return a v2.4 response. Well, it's almost been 6 months since the announcement was made. If you haven't already moved to our shiny new APIs, and we know there are quite a few of you out there who haven't, we urge you to get movin' or risk your application not working come June.
