Ongoing Work On More Semantic-Typed API
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This release, like the 20.01, continues the journey on defining the
semantic-based types instead of storage-based types within the API, so
you may have noticed this in the API changes.

Some of the changes are related to the infrastructure, and may be
bugfixes, they do not change the CRC of the message but affect the
representation on the wire. One particular commit we want you to pay
attention to, is
`b5c0d35f <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=b5c0d35f>`__,
which fixes the bug with the enum representation on the wire - before
it, even the enums declared as u8 or u16 were represented as u32 in the
API messages.

Another important commit we would like to call out explicitly as well is
`7dd63e5c <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=7dd63e5c>`__,
which pinned the address_family and ip_proto enum types to be u8 instead
of the default u32.

The above two commits will be primarily interesting for those who work
with the low-level APIs on VPP - the API frameworks should make these
under-the-hood changes transparent. However, we decided to call these
out, given that for those affected these will be pretty important
changes.

Another commit, that does not have the immediate impact at the moment,
but that is poised to improve the user interaction with the API is
`5c318c70 <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=5c318c70>`__.
This adds the tooling and ability to implement a structured process, by
which the API messages can evolve, while minimizing the impact to the
API users.
