Commit 99807672055b6bb86e44311a199592ceb35c72bd

Carlos Martín Nieto 2014-06-08T19:42:54

Change SOVERSION at API breaks Since the SOVERSION doesn't need to follow the library's version and simply needs to be monotonically increasing whenever we release something that breaks the ABI, we can set some number and allow multiple versions of the library to be installed side-by-side. We start here with the minor version as that's what we release for now, and it allows to backport this change to earlier versions.
