I just saw the Maven artifact com.fasterxml.jackson.core:jackson-databind:2.10.0.pr1 and was wondering what pr1 or pr could mean.
2.9.8 has recently been released, so 2.10.x is upcoming.
A quick glance at https://en.wikipedia.org/wiki/PR only offers "pull request", but that doesn't make sense in the context of this project since Jackson sees dozens of PRs between releases and what should 1 refer to then?
In this case, pr can means Preview Release, indicating that the version is a Beta version, open for users testing and feedback.
