May 2026 monthly summary (modularml/mojo). Focused on improving CI reliability and test determinism by enabling CPU-only testing for the Vision Rotary Embedding path and removing GPU gating. This change ensures tests run on CPU using DeviceRef.CPU and InferenceSession(devices=[CPU()]), with no GPU kernels dispatched. The CPU path is now the default Linux runner, reducing GPU-related timeout flakes and aligning the test suite with other CPU-only targets. Overall, this improves feedback tempo and stability of integration builds, enabling faster iterations on model tooling and tests.

April 2026 (2026-04) monthly summary for modular/modular. Key deliverables focus on backward compatibility and CI/test strategy improvements. The work preserves user expectations, reduces CI timeouts, and enhances local testing workflows.

March 2026 monthly summary for modular/modular: Focused on stabilizing CI and addressing flaky tests to improve release velocity and build reliability. The primary effort this month was a CI stability enhancement achieved by disabling a nondeterministic test and marking it as manual to prevent flaky failures from blocking pipelines. This directly reduces CI noise, shortens feedback loops, and enables more deterministic releases.
