Hello Fedora community,
I'm pleased to announce that we released v1.0.0 of the tool, which marks completion of the features expected to be implemented for the COPR back-end.
A detailed changelog is available here:
Among the newest features, the package now provides man-pages, command completion and a new `mpb-report` tool which generates a status report in markdown format for a given build.
Future development will likely focus on implementing other backends, probably a koji one and maybe a more generic one (based on ssh/mock).
As usual, please provide feedback, and don't hesitate to request for new features.

Hello Fedora community,
The Christmas period is coming, and soon after the Fedora mass rebuild will come and may lead to the creation of a bunch of FTBFS bugzillas.
I'd like to share with you the availability of a tool that we started to develop this year, which aims to help developers to assess the impact a change in their component will have on other components that depend on them.
I recently used it in order to prepare for the upcoming Autoconf 2.72 release, and with it uncovered about 84 build failures (out of 1197 packages depending on Autoconf) that would have been missed if I were following the "classical" workflow. This resulted in few bugs opened in corresponding components, and even upstream changes toward the Autoconf community, prior to the official 2.72 release.In the past weeks, it has also been used to assess the impact of porting Fedora to Modern C (by Florian Weimer) which tested about 10k packages and for the make 4.4 update (from DJ Delorie), which tested about 9k dependencies against this new version to look for breakage.Yet, the more users there will be, the more this tool will improve and be useful for the packagers.
This tool is called the mass prebuilder. I've written a blog post for Red Hat a while ago, which already contains a lot of details about it:
https://developers.redhat.com/articles/2022/09/26/find-errors-packages-through-mass-builds
There is a COPR package available to ease installation:
https://copr.fedorainfracloud.org/coprs/fberat/mass-prebuild/
And a detailed Howto available in the source README:
https://gitlab.com/fedora/packager-tools/mass-prebuild/-/blob/main/README.md
As of today, the tool provides most of the planned features, although it only uses COPR as a builder backend, whereas Koji is also planned on the long run (and likely others).
Since the tool is fairly new, it lacks manpages, may miss features you would expect and is likely to have bugs (even if we tried to limit them as much as possible).
Therefore, don't hesitate to open issues in the Gitlab repository if need be: https://gitlab.com/fedora/packager-tools/mass-prebuild/-/issues.
