contract-lab
Experimental successor project to contract — currently private.
The package contract-lab is currently only an internal experiment. The
background is that since 2026 LaTeX behaves drastically differently when the
command \DocumentMetadata is set (before \documentclass). Increasingly,
many parts of the LaTeX kernel for class and package authors are then replaced
by the still-evolving
latex-lab. The current release can
already differ substantially from the development version
latex-lab-dev. As long as this
remains unstable on the kernel side, it does not make sense to publish the
experiment on CTAN.
Whether this will eventually result in a package with similar functionality to
contract, something entirely different, or nothing
at all cannot be said at this time. The project is currently hosted privately
on Codeberg. Access is
restricted to privileged users involved in the development.
