Sep 1, 2025September 2025 monthly summary: Focused on security hardening, test reliability, and governance enhancements for zapier/zapier-platform. Delivered a new secret scrubber integrated into the error response path to censor sensitive data in URLs and environment variables, stabilized the test suite (build/tests, URL handling, httpbin/middleware/request-client) with async/await migrations and test structure refinements, and improved the Migration CLI with clearer scope definitions and removal of redundant flags. Also aligned versioning and release notes with the 17.8.0 schema, while maintaining compatibility with 17.7.1 downgrades as needed, and completed a maintenance task to switch from node-fetch to native fetch in the CLI. These efforts reduce data-leak risk, improve test determinism, simplify migrations, and strengthen release governance while leveraging existing tech stack.
