3.2.0

This is a bugfix release of Helidon and is recommended for all users of Helidon 3. Helidon 3 requires Java 17 or newer.

This release upgrades SnakeYaml from 1.32 to 2.0. Because of incompatible API changes in SnakeYaml 2 it is possible your application might be impacted if you use SnakeYaml directly. While we reccomend you do the upgrade, if that is not possible you may force downgrade SnakeYaml to 1.32 and Helidon 3.2.0 will still work.
