ChangeLog for CXP

[1.2.0] - 2025-05-30

Changed

  • Internal framework refactor: Migrated from Flask to FastAPI for improved asynchronous handling and performance.
  • Updated operational dependencies:
    • Added fastapi, uvicorn
    • Removed flask, gunicorn

Notes

  • No changes to Prometheus metrics endpoints, names, labels, or scrape behavior.
  • Existing Prometheus scrapers, dashboards, and alerting rules will continue to work as-is.
  • The internal implementation is now fully asynchronous with FastAPI, potentially improving concurrent scrape handling under heavy load.
  • Logging and startup messages will differ due to the new framework and ASGI server (uvicorn).
  • adjust the following settings for uvicorn as environment variables:
    • HOST
    • PORT
    • WORKERS (Default : 1)
    • LOG_LEVEL=(Default : warning)

⚠️ Breaking operational change: if your deployment or runtime environment specifically depends on Flask or Gunicorn, you'll need to adjust service definitions accordingly.
