Compatibility notes. Java 17+ and Gradle 8.4+ are the minimal supported versions.

PLEASE NOTE. This version is just a refreshed variant of 1.15.0, compatible with latest Gradle version (8.14/9.0). No PIT 1.19.0 features parity was developed.

Missing features:

1. Automatic releasing from CI to Maven Central and Gradle Plugins (as previously used CDeliveryBoy is not compatible with Gradle 7+).
2. Releasing also to Maven Central (not just only to Gradle Plugins).
