September 2025 performance snapshot for Selenium project work. Key features delivered include: (1) Unified Selenium Grid Node/Standalone images (NodeAllBrowsers) that support all major browsers (Chrome/Chromium, Edge, Firefox) in a single image with linux/amd64 targeting, an option to switch between Chrome/Chromium binaries, and image hardening by removing pre-generated certificates. (2) Kubernetes charts and image registry/version updates to support newer browser versions, expanded cross-browser test matrix, and alignment with latest CI versions, including patch timeouts for autoscaling. (3) CI/CD tooling and workflow enhancements with script linting/formatting checks, updated dependencies, Ubuntu runners, and standardized edge/Firefox release workflows, plus checkout branch standardization. (4) NodeBase video filename default addition to auto-name recordings (SE_VIDEO_FILE_NAME=auto) to simplify configuration. (5) Security hardening improvement by removing pre-generated self-signed certificates in images. In Selenium repo, fixed Distributor session rejection regression so requests are only rejected when no nodes support the requested capabilities, improving reliability for concurrent test loads.
