What’s new?

GraalVM/Mandrel 22.2

It was already possible to use it with Quarkus 2.11 but GraalVM/Mandrel 22.2 is now the default version for building native executables.

Kotlin 1.7

Our Kotlin extensions got upgraded to Kotlin 1.7.

SmallRye Config SecretKeys

Support for SmallRye Config SecretKeys has been added.

Microsoft SQL Server JDBC driver update

We were using a very old version of the Microsoft SQL Server JDBC driver, due to some issues when compiling to native executables. We were finally able to upgrade to version 11.2.0.jre11 in Quarkus 2.12.0.Final.
