Hello @bitschmidty, I'm new here and was exploring why the PR has failed some checks. I found out custom CI is failing due to remaining FIXME: markers in _posts/en/newsletters/2026-02-06-newsletter.md (e.g., FIXME:bitschmidty, FIXME:Gustavojfe). Apologies for the above noise. |

Title is a bit messy partly due to the name of the project. Perhaps this?
