Month 2024-11 focused on reliability, performance, and maintainability across saucectl and sauce-docs. Key outcomes include: 1) Unconditional npm registry deprecation warning implemented to ensure consistent user messaging; 2) CI testing frameworks upgraded (Cypress, Playwright, TestCafe) to align with current tooling; 3) File upload model refactor introducing a FileInfo struct to encapsulate file name, description, and tags for uploads; 4) Node_modules archive tagging added to caching with refactors to isolate project files, runner configs, and node_modules with validation; 5) Slack notification integration removal to simplify the project and reduce maintenance. In addition, CI tag naming improvements were implemented for descriptive environment-based names and short SHAs. Documentation updated to reflect version support and EOL for Cypress/TestCafe, with relevant config guidance.
