TeX Live 2025 was released today. All engines now create PDF-1.7 in LaTeX and plain format, with older formats (like 1.5 and 1.4) still supported.
MacTeX 2025 is now also available, coming with TeXShop 5.49, and working with the latest Apple Intelligence features, including Writing Tools.
TeX Live 2024 and MacTeX 2024 are now frozen, so consider installing the 2025 version when you would like to install updates in the future.
For TeX Live information and download, visit tug.org/texlive. MacTeX is available at tug.org/mactex. TeX Live and MacTeX are supported by the TeX Users Group, DANTE e.V. and more user groups, developers, testers, and users.
