Pre-release 4 of LaTeX 2025-06-01 is available for testing

We posted a couple of weeks ago that a ‘final’ development release of the 2025-06-01 kernel had gone to CTAN. A few things have come up in testing that pre-release, so we have updated again to pre-release 4. Hopefully that catches the issues without adding new ones - testing would be much appreciated.

Enjoy — Joseph
