News for the week of January 19, 2026: Rolldown reaches 1.0 release candidate, and a PDF library we all deserve. From the community: a better npm admin experience, supertype safety, and modern package.json targets.

Stand With Minnesota
We are native Minnesotans. The ICE occupation is affecting our community in so many ways and has disrupted daily life for thousands of us. Families are sheltering in place, fearing to go to work, let their kids walk to school, take the bus, or even attend school at all. Adults and children are being abducted from their workplaces, schools, cars, and homes with aggressive tactics and without due process. There have been dozens of well-documented violations of our civil liberties and rights as US citizens, including the illegal detainment of peaceful protestors, constitutional observers, and people of color. ICE has shot and killed two US citizens already in the span of 3 weeks: Renee Good, a mother of three, and Alex Pretti, a VA nurse. They are out of control, they are causing irreparable harm, and we want them out of our cities.
