The Internet Systems Consortium has stopped maintaining their DHCP client, which is standard on a lot of distros.
Debian has updated its documentation and now warns users to choose an alternative:

On Debian Unstable, I was already forced to uninstall it in yesterday’s upgrade.
If you’re using network-manager, you don’t need to worry, since it includes its own dhcp client, but for others, this might be relevant.
On Arch, this concerns the dhcpd package:

The Arch wiki article already states it’s unmaintained since January 2023. So Arch users have had almost a year to find another solution at this point.
