From: Christophe de Dinechin <dinechin@xxxxxxxxxx>
This patch series introduces changes in the ABI and API, and I expect
a few more to arrive shortly. So I tagged the ABI version as 0.01,
and all 0.x versions are considered as incompatible with one another
by default. When we reach ABI and API stability, we can bump to a
non-zero version number and then we will need to preserve ABI and API
compatibility within a major version moving forward.
