Hello dear maintainers, contributors, and others!

Yesterday, the weekly release process for 2.294 suffered a human error (from I) which led to a duplicated release 2.295.

Also, the Windows Weekly Package was unavailable for download (HTTP/404) from 2021-05-25 11:30 UTC until 2021-05-26 07:51 UT, due to a problem in the release process.

I’ve written a post-mortem on this URL: https://hackmd.io/@jenkins-infra/SJNjA5jKu to explain the chronology, impact, reasons that led to this "outages".

A set of proposal has been made in the document to avoid these errors and mistakes again: please feel free to add more in this email thread and/or by logging in and commenting the document.

My apologies for the additional work the duplicated release added on your shoulders.

Have a nice day all!
