Feb 1, 2026

February 2026 — Genesis repository: Delivered critical collision-detection reliability improvements, introduced performance benchmarks for robotics workloads, and optimized CI to accelerate delivery pipelines. The month focused on strengthening simulation accuracy, establishing measurable performance baselines, and reducing feedback loop times in CI/CD.

January 2026

17 Commits • 4 Features

Jan 1, 2026

January 2026 delivered a set of targeted improvements across Genesis and ROCm/pytorch that strengthen performance measurement, stabilize the CI pipeline, and accelerate benchmarking. Core progress includes GPU memory monitoring for benchmark tests in Genesis with standardized artifacts, improved reporting, and a memory data upload path, complemented by fixes to exit codes and CSV/text uploads. CI reliability was significantly enhanced through uv-based unit tests, more robust Mesa installations, removal of unused apt sources, ensured code checkout in workflows, explicit CI outputs, and expanded memory metrics in performance reports. Benchmark execution was overhauled to support multi-step runs, updated environment tooling, and caching to speed up and stabilize results. The codebase benefited from cleanup and minor improvements to improve maintainability and readability. In ROCm/pytorch, a failing DLPack test comparison was fixed to prevent AssertionError, improving test reliability across the stack.
