The libtool current:revision:age numbers change from 1:0:0 to 2:0:0.
Details:
http://www.gnu.org/software/libtool/manual/libtool.html#Updating-version-info
This changes the library filename (e.g. on Linux) from
libsigrokdecode.so.1.0.0 to libsigrokdecode.so.2.0.0, the SONAME (+symlink)
becomes libsigrokdecode.so.2.
# Carefully read the libtool docs before updating these numbers!
# The algorithm for determining which number to change (and how) is nontrivial!
