JVM

Gradle 9.9.0 compiles Kotlin DSL scripts incrementally (Gradle reports 65% faster recompiles in one test), applies test filters to non-method JUnit tests, and changes Problems API IDs.

TornadoVM 6.0 removes its JNI and JVMCI dependencies, unifying Java GPU acceleration into one build spanning JDK 21 through 27 while retiring three hardware backends.

JUnit 6.1.0, released May 19, absorbs JUnit Pioneer's locale, timezone, and system-property extensions into core while replacing ForkJoinPool with a simpler thread pool for parallel test execution.

Gradle 9.5.0 and its patch 9.5.1 bring clearer diagnostics, CI-resilient wrapper downloads, and long-awaited Kotlin DSL improvements.

After years of development, sbt 2.0 has reached RC12 with 60+ ecosystem plugins ported, targeting a stable release within weeks to months.
