Bad soname version in current git master

[GoogleCodeExporter]

Commit cd7aece14e2aac0669292c95ab42de6e267a5034 sets the library SOVERSION to 
the major version of the package (currently 2).

However, the current git master (or even 2.1.1) is not backward compatible at 
an ABI level with previous versions (2.0) of the library. At least one symbol 
was dropped at some point.

Please increment the SOVERSION, or go back to using MAJOR.MINOR (or maybe even 
MAJOR.MINOR.MICRO).
