New version testing

[xvik]

A new large guicey update is (almost) ready: see release notes (overall documentation is not ready yet)

The same changes released in 3 branches (as release candidates):

• Dropwizard 3: 6.3.0-rc.1
• Dropwizard 4: 7.2.0-rc.1
• Dropwizard 5 (rc.2): 8.0.0-rc.2

Please try the new version. I want to make sure there are no (unwanted) breaking changes.

General release for dropwizard 3 and 4 would appear in a couple of weeks - as soon as I finish updating documentation.
