# FORKED REPOSITORY

This fork was made to create a version compatible with Spring Boot 4 but using Jackson 2.
This is required because the mere presence of Jackson 3 on the classpath can trigger autoconfiguration or feature detection
in some parts of Spring/Spring Boot.
While we can decorrelate the upgrade to Spring Boot 4 from the upgrade to Jackson 3, to Apps are encouraged to migrate to Jackson 3 soon.

Deploy to our Maven repo with `mvn deploy -DaltDeploymentRepository=<repoId_from_settings.xml>::default::<repoUrl> (-DskipTests)`.

We won't maintain this fork for longer than necessary for internal use and support only our internal use cases.
