Version 5.4.0 of GNU awk (gawk) has been released. This is a major release with a change in gawk's default regular-expression matcher: it now uses MinRX as the default regular-expression engine.

This matcher is fully POSIX compliant, which the current GNU matchers are not. In particular it follows POSIX rules for finding the longest leftmost submatches. It is also more strict as to regular expression syntax, but primarily in a few corner cases that normal, correct, regular expression usage should not encounter.

Because regular expression matching is such a fundamental part of awk/gawk, the original GNU matchers are still included in gawk. In order to use them, give a value to the GAWK_GNU_MATCHERS environment variable before invoking gawk.

[...] The original GNU matchers will eventually be removed from gawk. So, please take the time to notice and report any issues in the MinRX matcher, so that they can be ironed out sooner rather than later.

See the release announcement for additional changes.

Version 148 of Firefox has been released. The most notable change in this release is the addition of a "Block AI enhancements" option that allows turning off "new or current AI enhancements in Firefox, or pop-ups about them" with a single toggle.

With this release, Firefox now supports the Trusted Types API to help prevent cross-site scripting attacks as well as the Sanitizer API that provides new methods for HTML manipulation. See the release notes for developers for changes that may affect web developers or those who create Firefox add-ons.

This major release contains many new and improved functions. Among other things, it brings better support for classdef objects and arrays, broadcasting for special matrix types (like sparse, diagonal, or permutation matrices), updates for Matlab compatibility (notably support for the nanflag, vecdim and other parameters for many basic math and statistics functions), and performance improvements in many functions.

See the release notes for details.

The 7.0 merge window closed on February 22 with 11,588 non-merge commits total, 3,893 of which came in after the article covering the first half of the merge window. The changes in the second half were weighted toward bug fixes over new features, which is usual. There were still a handful of surprises, however, including 89 separate tiny code-cleanup changes from different people for the rtl8723bs driver, a number that surprised Greg Kroah-Hartman. It's unusual for a WiFi-chip driver to receive that much attention, especially a staging driver that is not yet ready for general use.

One of Weston's fundamental pillars has always been making the most efficient use of display hardware. Over time, all the work we did to track and offload as much work as possible to this efficient fixed-function hardware has come at the cost of eating CPU time. In the last couple of release cycles, we've focused really hard on improving performance on even the most low-end of devices, so not only do we make the most efficient use of the GPU and display hardware, but we're also really kind on your CPU now. As part of that and to improve our tooling, Weston 15 now comes with support for the Perfetto profiler.

When we originally evaluated Rust back in 2024, we rejected it because it's not great at C++ style OOP. The web platform object model inherits a lot of 1990s OOP flavor, with garbage collection, deep inheritance hierarchies, and so on. Rust's ownership model is not a natural fit for that.

But after another year of treading water, it's time to make the pragmatic choice. Rust has the ecosystem and the safety guarantees we need. Both Firefox and Chromium have already begun introducing Rust into their codebases, and we think it's the right choice for Ladybird too.

Large language models are being used to translate existing code.

The PostgreSQL project has been chugging along for decades; in that time, it has become a thriving open-source project, and its participants have learned a thing or two about what works in attracting new contributors. At FOSDEM 2026, PostgreSQL contributor Claire Giordano shared some of the lessons learned and where the project is still struggling. The lessons might be of interest to others who are thinking about how their own projects can evolve.

The closed-source chat platform Discord announced on February 9 that it would soon require some users to verify their ages in order to access some content — although the company quickly added that the "vast majority" of users would not have to. That reassurance has to contend with the fact that the UK and other countries are implementing increasingly strict age requirements for social media. Discord's age verification would be done with an AI age-judging model or with a government photo ID. A surprising number of open-source projects use Discord for support or project communications, and some of those projects are now looking for open-source alternatives. Mastodon, for example, has moved discussion to Zulip. There are some alternatives out there, all with their own pros and cons, that communities may want to consider if they want to switch away from Discord.

Dianne Skoll, creator and maintainer of the command-line calendar and alarm program Remind, has announced the release of The Book of Remind. As the name suggests, it is a step-by-step guide to learning how to use Remind, and a useful supplement to the extensive remind(1) man page. The book is free to download.

Douglas DeMaio has announced that Jeff Mahoney's new governance proposal for openSUSE, which was published in January, is moving forward. The new structure would have three governance bodies: a new technical steering committee (TSC), a community and marketing committee (CMC), as well as the existing openSUSE board.

The discussions during the meeting proposed that the Technical Steering Committee should begin with five members with a chair elected by the committee. The group would establish clear processes for reviewing and approving technical changes, drawing inspiration from Fedora's FESCo model. Decisions for the TSC would use a voting system of +1 to approve, 0 for neutral, or -1 to block. A proposal passes without objection. A -1 vote would require a dedicated meeting, where a majority of attendees would decide the outcome. Objections must include a clear, documented rationale.

Discussions related to the Community and Marketing Committee would focus on outreach, advocacy, and community growth. It could also serve as an initial escalation point for disputes. If consensus cannot be reached at that level, matters would advance to the Board.

[...] No timeline for final adoption was announced. Project contributors will continue discussions through the GitLab repository and future community meetings.
