I am an astronomer and was at a conference when this headline broke. Obviously we ignored this and read the actual papers, e.g. https://arxiv.org/abs/2404.03002. There you can see that the dark energy equation of state parameter w0 = -0.99 +0.15/-0.13, which is not at all significantly different than w0 = -1. That is, no time evolving dark energy. When combined with other cosmological results, the joint analysis slightly favors w0 > -1 rather than w0 = -1 at the ~2.5sigma level or so, but it depends which other results you factor in.
