LaTeX3 Development Code
Some of the current LaTeX3 development code is held under version control in a SVN repository and can be accessed publicly via a web interface, where it can be downloaded as single files. However, you might prefer to get hold of the files via anonymous SVN access in which case you can get a working copy from the repository at https://latex-project.org/svnroot/experimental/trunk/ using a Subversion client.
Please remember that this material is intended only for experimentation and comments; thus any aspect of it, e.g., the user interface or the functionality, may change and, in fact, is very likely to change. For this reason it is explicitly forbidden to place this material on CD-ROM distributions or public servers.
These concepts, as well as their implementation, are under discussion on the list LATEX-L. You can join this list, which is intended solely for discussing ideas and concepts for future versions of LaTeX, by sending mail to listserv@URZ.UNI-HEIDELBERG.DE containing the line
