[$] Python packaging council approved

The Python packaging world now has a formal governance council, of the form described in PEP 772 ("Packaging Council governance process"), which was approved by the steering council on April 16. It has been over a year since the PEP was first proposed in February 2025 and it has undergone lengthy discussions in multiple postings to the Python discussion forum. The packaging council will have "broad authority over packaging standards, tools, and implementations"; it will consist of five members who will be elected in a vote that is likely to come in Juneโ€”after PyCon US 2026 is held mid-May.

Security review of Plasma Login Manager (SUSE Security Team Blog)

SUSE's Security Team has published a detailed blog post on their recent review of the Plasma Login Manager version 6.6.2, which was forked from the SDDM display manager. While most of the code remains the same, the new upstream added a privileged D-Bus helper called plasmaloginauthhelper, which suffers from defense-in-depth security issues. [...] Based on the high severity of the defense-in-depth issues shown in this report, our assessment is that there is effectively no separation between root and the plasmalogin service user account. At this time there is no bugfix available by upstream, but a security fix is planned for the next Plasma release on May 12. We have not been involved in upstream's bugfix process so far and have no knowledge about the approach that will be taken to address the issues from this report.

The Intel Lunar Lake CPU Performance Gains On Linux Over The Past Year

Recently I ran benchmarks looking at the Xe2 graphics performance gains on Intel Lunar Lake over the past year with what's shipped by Ubuntu and comparing against our original tests of the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition. With those Lunar Lake iGPU benchmarks out of the way, here is a look at how the Lunar Lake CPU performance has evolved on Linux since April 2025.
