One of our goals was making Network Time Security (NTS) the default in Chrony, not just for Ubuntu 25.04 Plucky Puffin, but beyond.

We’ve now reached that milestone as part of the ongoing development of Ubuntu 25.10 Questing Quokka.

I just posted my latest #Ubuntu #blog that describes my plans for the project's documentation - and how we'll use that to grow a more sustainable and engaged community.

Check it out on the Ubuntu Discourse! https://discourse.ubuntu.com/t/58694

Revitalising Ubuntu Project Documentation

Introduction Back in February I wrote some thoughts on Ubuntu’s documentation and its role within the community. For a mostly-online software community, documentation is one of our most critical forms of communication. In the last two years there has been lots of focus on the technical aspects of our documentation (how-to guides, tutorials, etc.), but I’d like to focus more on what I’m calling the “Ubuntu Project Documentation” over the coming months. Documentation isn’t only about technical h...

This week Michael Hudson-Doyle of the #Ubuntu Foundations team published a write-up of our experimentation with the `-O3` GCC flag by default in the distribution.

The tl;dr is that we don't yet believe that the change makes sense globally, but there are certainly come packages that would benefit from using the increased optimisation level.

See the post here: https://discourse.ubuntu.com/t/benchmarking-a-distribution-and-some-o3-results/58027

Benchmarking a distribution (and some \-O3 results)

In our previous Foundations update @mclemenceau shared an update on some of the experiments we conducted during the Plucky Puffin cycle, in particular about our decision to revert the change to the -O3 optimization level by default on amd64. As promised here is a few more details about what went into this project, methods used and challenges encountered. Results of -O3 experiment tl;dr Performance is slightly worse and packages are slightly bigger with -O3 by default and we will revert the chan...
