BPF offers useful safety guarantees, but Kumar Kartikeya Dwivedi wants BPF programs to be even safer. At the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit, he led a session (slides) discussing the possibility of adding domain-specific invariants to BPF programs. It was not a discussion intended to lead to the implementation of any particular kernel feature, but rather an overview of why additional formal verification might be needed, and how it could work with the existing BPF ecosystem.

The Django Python web-framework project has announced that it has accepted an annual release cycle proposal. This means that the project is moving from a somewhat complicated schedule that interspersed short-lived feature releases and long-term-support (LTS) releases to a simpler annual cycle where each release is supported for three years.

Every feature release gets three years of support: one year of mainstream bugfixes, then two years of security and data-loss fixes. The "LTS" label is retired — every feature release now carries that same, unique commitment.

No more LTS gap: no racing a deadline to jump two years of changes at once. Upgrade one year at a time, whenever suits you within the support window. Three versions are supported at any time, giving third-party packages a clear, rolling target.

This will take effect with the upcoming Django 2028 release, expected in January 2028.
