WebKit Igalia Periodical #51

15 December, 2025 - Categories: wip

Update on what happened in WebKit in the week from December 8 to December 15.

In this end-of-year special have a new GMallocString helper that makes management of malloc-based strings more efficient, development releases, and a handful of advancements on JSC's implementation of Temporal, in particular the PlainYearMonth class.

Cross-Port 🐱

Added GMallocString class to WTF to adopt UTF8 C strings and make them WebKit first class citizens efficiently (no copies). Applied in GStreamer code together with other improvements by using CStringView. Fixed other two bugs about string management.

JavaScriptCore 🐟

The built-in JavaScript/ECMAScript engine for WebKit, also known as JSC or SquirrelFish.

Releases 📦️

Development releases of WebKitGTK 2.51.3 and WPE WebKit 2.51.3 are now available. These include a number of API additions and new features, and are intended to allow interested parties to test those in advance, prior to the next stable release series. As usual, bug reports are welcome in Bugzilla.

That’s all for this week!
