Welcome to the LWN.net Weekly Edition for March 13, 2025

• New terms of service for PyPI: the Python module repository seeks to redefine its relationship with its users.
• Zig's 0.14 release inches the project toward stability: this programming language is still some distance from 1.0, however.
• The road to mainstream Matrix: a FOSDEM talk on how Matrix got to its current place and what may be coming next.
• Timer IDs, CRIU, and ABI challenges: a demonstration of how easy it is to get caught having to maintain an ABI that a project never meant to provide.
• Hash-based module integrity checking: an attempt to reconcile integrity checking with reproducible builds.
• Capability analysis for the kernel: a promising LLVM feature that may help to prevent locking errors — someday.

This week's edition also includes these inner pages:

• Brief items: Brief news items from throughout the community.
• Announcements: Newsletters, conferences, security updates, patches, and more.

Please enjoy this week's edition, and, as always, thank you for supporting LWN.net.
