Pretesting TeX Live

All of the TeX Live community greatly appreciates all testing of TeX Live before the official release. The more people who test in advance, the better the final release can be. It is also the best opportunity to influence and improve the behavior of TL. For dates and deadlines, please see the TeX Live home page.

So please try it if you like, but 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”.

On this page: downloading - installing - testing - updating - reporting - news.

Downloading

You can retrieve the pretest files from one of these hosts: copy-paste an http or ftp url when running the installer directly, or use an rsync url for mirroring, as described below. (Our thanks to these sites 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 unless something goes wrong. The mirror hosts should all be up to date within a couple of hours after that.

Installing

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 find the value for location). The location must be an ftp or http url (not rsync).

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.

Testing

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 check that they still work as expected.

Updating

After a successful installation, you can update from the tlpretest repository using tlmgr from time to time, if you wish. In the event of unusually drastic changes during the pretest you may have to reinstall.

Reporting problems

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

Notable changes

The main TeX Live documentation and translations are not yet fully updated. Meanwhile, aside from the pervasive updates to new releases of packages and programs, here is a terse list of major user-visible changes:

LaTeX2e (full LaTeX2e news)
LaTeX2e now incorporates, by default, changes previously included only by explicitly loading the fixltx2e package, which is now a no-op (CTAN announcement). A new latexrelease package and other mechanisms allow for controlling what is done. The included LaTeX News #22 and LaTeX changes documents. have details. Incidentally, the babel and psnfss packages, while core parts of LaTeX, are maintained separately and are not affected by these changes (and should still work).

Internally, LaTeX2e now includes Unicode-related engine configuration (what characters are letters, naming of primitives, etc.) which was previously part of TeX Live. This change is intended to be invisible to users; the names of a few low-level internal control sequences are different, but the behavior should be just the same.

pdftex (full pdfTeX news)
Support JPEG Exif as well as JFIF; do not even emit a warning if \pdfinclusionerrorlevel is negative; sync with xpdf-3.04
luatex (full LuaTeX news)
New library newtokenlib (detailed TUGboat article) for scanning tokens; bug fixes in the normal random number generator and other places.
xetex (full XeTeX news)
Right-to-left support now based on the original TeX-Xet extension, fixing special handling for colors, hyperlinks, etc.; directionality can be switched inside math mode; \TeXXetstate and \predisplaydirection are still available, but have no effect; XDV opcodes changed; xdvipdfmx binary looked for first as a sibling to xetex.
metapost (full MetaPost news)
A new numbersystem binary is available. New Japanese-enabled upmpost and updvitomp included, analogous to up*tex.
Infrastructure: fmtutil[-sys]
has been reimplemented and now reads fmutil.cnf on a per-tree basis, analogous to updmap. Web2C mktex* scripts (including mktexlsr, mktextfm, mktexpk) now prefer programs in their own directory, instead of blindly using the existing PATH.
Platforms
*-kfreebsd removed. Support for some additional platforms is/will be available as custom binaries.

If you find other important changes that should be noted, please report them. This is one of the most important things pretesters can help with.
