WebKit Igalia Periodical #42

When using libwebrtc, support has been added to register MDNS addresses of local networks as ICE candidates, to avoid exposing private addresses.

JavaScriptCore's implementation of Temporal received a flurry of improvements:

• Implemented the toString, toJSON, and toLocaleString methods for the PlainMonthDay type.

• Brought the implementation of the round method on TemporalDuration objects up to spec. This is the last in the series of patches that refactor TemporalDuration methods to use the InternalDuration type, enabling mathematically precise computations on time durations.

• Implemented basic support for the PlainMonthDay type, without most methods yet.

• Brought the implementations of the since and until functions on Temporal PlainDate objects up to spec, improving the precision of computations.

WebKitGTK will no longer support using libsoup 2 for networking starting with version 2.52.0, due in March 2026. An article in the website has more details and migrations tips for application developers.

Fixed the jittering bug of the docked Web Inspector window width and height while dragging the resizer.

WebKitGTK 2.50.1 and WPE WebKit 2.50.1 have been released. These include a number of small fixes, improved text rendering performance, and a fix for audio playback on Instagram.

A security advisory, WSA-2025-0007 (GTK, WPE), covers one security issue fixed in these releases. As usual, we recommend users and distributors to keep their WPE WebKit and WebKitGTK packages updated.

Updated the API test runner to run monado-service without standard input using XRT_NO_STDIN=TRUE, which allows the WPE and GTK bots to start validating the WebXR API.

Submitted a change that allows relaxing the DMA-BUF requirement when creating an OpenGL display in the OpenXRCoordinator, so that bots can run API tests in headless environments that don't have that extension.
