Testing TeX Live before release

We greatly appreciate any testing of TeX Live before the official release. The more people who do so, the better the final release will be. It is also a good chance to influence and improve the behavior of TL.

Please try not with the expectation that “everything should work perfectly” (it won't), but rather “I'll try this out and see if I can help improve it”.

You can retrieve the pretest files from one of these hosts (right-click on the chosen host and use “copy link location” or your browser's equivalent to get a specific url to paste). Our thanks to all of them for making their space and bandwidth available.

You can either do a network installation of TL or mirror the whole directory:

The pretest build runs nightly, ending around 5am Denmark time (+0200 UTC) unless something goes wrong. The mirror hosts should all be up to date within a couple of hours after that.


After downloading as above, you can run the script install-tl (Unix) or install-tl.bat (Windows) to perform the installation:

If you are performing a network installation, the pretest repository location from which to install must be specified, as shown in these examples (see downloading above for how to get a value for location).

But in the case of installing from your own mirrored repository, you should omit -repository location from the given command lines.

For information on all of the installer options, run install-tl --help, or see the install-tl documentation page.


After a successful installation, please first try simple test documents, such as latex small2e. If that works, even more useful is to try your real-life documents, to make sure they still work as expected.


After a successful installation, you can update from the tlpretest repository using tlmgr from time to time, if you wish. In the event of drastic changes during the pretest you may have to reinstall, but this is not usual.

Reporting problems

Please email bug reports, suggestions, comments on TeX Live itself (the installation process, tlmgr, etc.) to tex-live@tug.org. Bugs about specific packages should be reported to the package maintainers; TeX Live's job is to install (some of) what is available on CTAN, not make changes on top of it. Resources for general questions and requests for help using TeX are available separately.

Notable changes

The main TeX Live documentation and translations are not yet fully updated. Here is a terse list of major user-visible changes:

If you discover other important changes we should note, please let us know.
