When was Esri File Geodatabase API made available?

See Inside Geodatabase: File Geodatabase API Details blog post.

The are some key limitations, though. If I were to name the most important ones, it would probably be that editing classes participating in relationships is not fully supported, as well as editing data in geometric networks. Also, support for rasters is not included at all in the first version.

Some of the limitations mentioned in the blog post are understandable, but still, I am very disappointed that after so many years of waiting, ESRI still can't get it quite right.

The C++ API is now available at ArcGIS Resource Center - File Geodatabase API.

An Esri blog posting announced that the Esri File Geodatabase API Is Now Available on 3 June 2011.
