Nov 1, 2025November 2025 (OpenVADL/openvadl) focused on stabilizing PPC64 support and expanding testing to drive reliability and velocity. Key PPC64 core fixes corrected XO arithmetic handling, GPR logic, XER width, and load update behavior, improving instruction semantics and runtime stability. Expanded PPC64 testing coverage, added and refactored tests, and improved the test infra references to ensure broader validation of PPC64 behavior. Modernized the PPC test framework with new cosimulation capability and 64-bit mode support, while streamlining the infra to reduce fragility.

Sep 1, 2025September 2025 monthly summary for OpenVADL/openvadl: Delivered interactive console input support for Gradle runs by configuring JavaExec to use standardInput (System.in) in build.gradle.kts, enabling interactive sessions when running the application via Gradle. This change improves debugging, testing, and scripting workflows in development and CI environments. No critical bugs fixed this month; maintenance focused on implementing the feature and validating compatibility with the Kotlin DSL Gradle scripts. The update enhances developer productivity, reduces friction for input-driven scenarios, and sets the stage for future enhancements that rely on interactive input. Technologies demonstrated include Java/Gradle Kotlin DSL (build.gradle.kts), JavaExec, and standard input handling, with traceability to commit fd88c358b7c2efd8b46cabc4f201bc84c4da15ee.
