Last month it was noted on Phoronix that Canonical's kernel team is looking at folding their low-latency kernel optimizations into their generic kernel builds. Right now Ubuntu maintains a separate "lowlatency" kernel flavor with Kconfig tweaks in the name of low-latency responsiveness as an alternative to their "generic" kernel default, but for Ubuntu 24.04 LTS it continues looking like they'll move forward with this change of incorporating the changes into their default kernel build.
In addition to exploring low-latency changes for the "generic" kernel image, frame pointers by default, and possible x86-64-v3 optimizations, another area being invested into feature work for this next long-term support release is on the desktop provisioning side. Building off work of their new Ubuntu desktop installer and unifying the installation tech that has already been used by Ubuntu Server, Canonical is hoping for a nice desktop provisioning experience in facilitating automated installations, managed desktop setups within enterprises, and OEM/ODM deployments.
For fans of the Ubuntu Touch platform maintained by UBports for enjoying Linux on tablets and smartphones is out with their 4th Over The Air update based on the Ubuntu 20.04 LTS base.
