July 2025 (apache/hamilton): Delivered two high-impact changes enhancing governance, branding, and maintenance efficiency. (1) ASF Branding in Documentation: integrated incubator logo and ASF links into the docs footer and added a new left-navigation section to align with ASF incubator branding per issue #1346. (2) Removal of Unsupported Ray Workflows: removed RayWorkflows from the Hamilton library, updated unit tests (Hugging Face and Kedro), and skipped a Hugging Face test on Python 3.8 due to the upcoming removal of support. These changes improve governance clarity, reduce maintenance overhead, and stabilize the CI/test suite.
