Simon,

I noticed that you recently uploaded ruby-minitest 6.0.x to unstable.
The 6.0.x series is an alpha release with major breaking changes.

https://github.com/minitest/minitest/blob/master/History.rdoc

It is not compatible with ruby-rails < 8.0.

This update is causing the autopkgtests of the majority of dependencies to fail.

As Debian currently has rails 7.2.3, I would recommend we upload
ruby minitest 6.0.1+really5.27.0 to unstable and 6.0.1+really6.0.1
to experimental.  I don't think that Debian is ready yet for ruby-rails 8.x.
Redmine, at least, isn't.  It currently needs exactly what Debian has (7.2.3).

As a side note, Redmine is now entangled in three transitions:

auto-upperlimit-ruby-sqlite3
auto-upperlimit-ruby-mail
auto-upperlimit-ruby-rack

My recommendatin is that we prevent any further transitions unless absolutely necessary
until we can resolve these three.
