Maven release very old (2015)

The most recent tagged release in the maven repository is 1.0-beta-2 from 2015. This is using guava 19.0. The current build is using guava 28.1. I would prefer to be able to have a dependency on caliper by just using the maven repository.

Can you release a more recent tagged version?
