MarsSeed [1] filed a deletion request for ruby-activesupport-4.2.10 [2]: It is not useful to keep this fixed-version Ruby gem from 2017. The latest patchlevel version of the same is 4.2.11.3 from May 15, 2020, which is API-compatible with this one, but this package here is unupdateable because of the hard, explicit version fix.
