Matthieu Clemenceau has published a status update on Ubuntu 25.04 (Plucky Puffin) development to the Ubuntu Discourse forum. This includes updates on Ubuntu's adoption of Dracut as an alternative to initramfs-tools, a move to a single ISO for arm64 devices rather than device-specific images, and reverting the planned O3 optimization flags for Plucky Puffin.

Earlier in this cycle, we announced plans to enable the O3 optimization level for all Ubuntu packages by default. As part of this effort, we conducted extensive benchmarking, which revealed that while some workloads saw improvements, overall system performance slightly declined, and binary sizes increased. Given these results, we are likely to revert this change soon.

The beta for Ubuntu 25.04 is planned for March 27, with the final release scheduled on April 17.

Highlights of the NVIDIA 570 graphics driver series include VRR (variable refresh rate) support on multi-monitor setups, along with a new conceal_vrr_caps kernel module parameter to enable usage of features on some displays, such as ULMB (Ultra Low Motion Blur), which are incompatible with VRR.

On January 20, Thomas Weißschuh shared a new patch set implementing an alternate method for checking the integrity of loadable kernel modules. This mechanism, which checks module integrity based on hashes computed at build time instead of using cryptographic signatures, could enable reproducible kernel builds in more contexts. Several distributions have already expressed interest in the patch set if Weißschuh can get it into the kernel.
