Developer Valorie Zimmerman posted a message on the Kubuntu-devel mailing list a couple of days ago to officially announce that Kubuntu 18.04 LTS (Bionic Beaver) is the last Kubuntu release to offer 32-bit ISO images, as starting with Kubuntu 18.10 (Cosmic Cuttlefish) they won’t be supporting new 32-bit installations. As already widely reported, the removal of the 32-bit install media revolution has begun amongst official Ubuntu flavors. The first to take the big step was Ubuntu MATE, followed closely by Ubuntu Budgie, Ubuntu Studio, and Ubuntu Kylin. After an official proposal from developer Bryan Quigley, Xubuntu and Kubuntu followed too.
