Sorry for that.  Directly checking the following macros of <otf.h> is
easier.

/* Version name of this library.  */
#define LIBOTF_VERSION "0.9.15"
/* Major version number.  */
#define LIBOTF_MAJOR_VERSION 0
/* Minor version number.  */
#define LIBOTF_MINOR_VERSION 9
/* Release (i.e. patch level) number.  */
#define LIBOTF_RELEASE_NUMBER 16

Yes.  The current library is libotf.so.0 (linked to libotf.so.0.0), but
the new one will be libotf.so.1 (linked to libotf.so.1.0.0).
