Hi Remi,

could you push an updated version for Fedora 42 too? (would be great for people who are late in upgrading, since it seems fedora 42 has not been officially EOL-ed yet)?

Sorry, but this is not possible. The Fedora build system is closed; no build allowed, no update allowed.

Workaround: use the package in my repo (which is usually open for ~3 months after EOL, until F45 is branched)
https://rpms.remirepo.net/fedora/42/remi/x86_64/repoview/roundcubemail.html

You even have the choice between versions 1.5/1.6/1.7
You also have security fixes for PHP itself
