3.1.0

This is a minor release of Helidon and is recommended for all users of Helidon 3. In addition to bug fixes and minor enhancements, this release contains two dependency upgrades that could have a small impact on compatibility. These are:

• OCI SDK 3.0. Note that if you are using Helidon MP OCI SDK integration then you will not need to specify an HTTP Client Library as the Helidon support will do that for you.
• GraalVM Native Image 22.3.0.
