Release Train Ockham (2020.0.0)

This page contains a list of the most significant features and bugfixes implemented in the Spring Data Ockham release train that will not be back-ported into Neumann service releases. With this release train, we switch to a calver-based versioning scheme for the release train. The version follows the pattern YYYY.minor.micro where minor starts at 0 each year and gets incremented for each release in that year.
