The LaTeX2e Kernel Code Repository


This repository hosts development of the core LaTeX distribution, which comprises:

  • The LaTeX kernel itself (base)
  • LaTeX team documentation (doc)
  • Packages which must be available (required). These are
    • Essential tools (tools)
    • Core graphics and color support (graphics)
    • Support for multiple languages (babel)
    • Key mathematics support (amsmath)

The master public Git repository is hosted on GitHub.


Only issues specifically related to these components should be logged with the team on GitHub. The LaTeX ecosystem is large, and there are many (thousands) of additional packages not maintained by us: issues related to the use of those need to be reported to the relevant maintainers.

To help you making the right decision where to report an issue we ask to start your minimal example file showing the problem always with


More details on creating issue reports for the core LaTeX distribution are given in our CONTRIBUTING guide.


We are unable to provide advice/support here: community sites such as TeX-LaTeX StackExchange and The LaTeX Community are available for general help. See also the help pages on our website for further suggestions.

Code fixes

Changes to the core LaTeX distribution have to be approached bearing in mind the importance of maintaining stability. This means that all changes have to be carefully weighed up, balancing the issues addressed by a change with the effects on existing documents. We strongly suggest raising suggestions on the LaTeX-L mailing list early.
