What’s Changed

This release brings major improvements across the engine, editor (utiLITI), input system, file I/O, iconography, documentation, build tooling, and overall stability. The most notable change is our migration towards our own custom input framework: Say goodbye to JInput, say hello to Input4j, improving the cross platform support and eliminating the need to deploy native third party binaries along the engine by utilizing the new(ish) Java FFM API. We’ve also migrated the engine to Java 25 and Gradle 9, improved the release pipeline, and resolved some reported bugs. After 1 year of not publishing a release, the improvements to our build and release pipelines guarantee that we can build releases with less manual effort in the future - and we’ve solved the problem of not being able to publish artifacts to Maven Central via the OSSRH anymore. Please don’t be confused about the versioning of this release: There was a 0.11.0 artifact published to Maven Central that is functionally identical, but our build pipeline had uploaded the utiLITI artifacts to itch.io with the wrong version tag, which we’ve addressed with the 0.11.1 patch.
