The TL pretest is over. See you next year.
The final version of last year's page is still below, for the curious.
Pretesting TeX Live 2022
The entire TeX Live community greatly
benefits from all testing 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. Please
give it a try if you can.
As distributed, the pretest will not interfere with any existing
installations of TeX, either native TeX Live or operating system
On this page: 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. And more mirrors are welcome.
You can either do a network installation of TL or mirror the whole
- To do a network installation, download either
install-tl-unx.tar.gz (Unix) or install-tl.zip
(larger; Windows or Unix), unpack it, and run the included
install-tl script, as described below. To reiterate: you must
use install-tl from the pretest; trying to work with a TL installation
from previous years will fail completely.
- To mirror the whole directory, rsync is the most efficient method:
rsync -a --delete --exclude="*.pkg*" somemirror::/some/path/ /your/local/dir
Add -v if you want to see the names of the files as they
Add -L if your system does not support symbolic links.
After mirroring the directory, run the install-tl script, below.
You can use wget or other tools to mirror via http or ftp if you
must. Regardless of the method, do not fail to exclude
mactex* or you will be doubling the (already large) transfer.
On the other hand, if you are only interested in MacTeX, you can mirror/download only the full
mactex-*.pkg file (several gb) or mactex-basictex-*.pkg
(100+mb), as in, for the full MacTeX:
rsync -a --delete --include="mactex-2*" --exclude="*" somemirror::/some/path/ /your/local/dir
For regular installations via download (i.e., not mirroring), we
highly recommend installing the
LWP Perl package if you don't have it.
64-bit Windows binaries are not included in TL. You can
get them as either the natively-compiled
binaries from Akira Kakuto (has its own instructions), or the mingw-compiled binaries from Luigi Scarso plus his auxiliary programs (install as a custom binary set).
The pretest build runs nightly, ending by 04:00 Copenhagen time
unless something goes wrong. The mirror hosts should all be up to date
within a few hours after that. (Current time in Denmark: Wednesday, 05-Oct-2022 01:46:22 CEST.)
After downloading as above, you can run the script
install-tl (Unix) or install-tl-windows.bat (Windows)
to perform the installation. We just use install-tl as the
command name in these examples:
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 the
location urls). The location must be an ftp or http url (not
But in the case of installing from your own mirrored repository, you
should omit -repository location from the given command
- install-tl -repository location -gui text
for text (command line) mode; this is the default on normal Unix, but
not on Windows or Macs.
- install-tl -repository location -gui
is the default on Windows and Macs. It runs a Tcl/Tk-based GUI if
Tcl/Tk is available, simple at startup but with a button to invoke
the advanced interface. If Tcl/Tk is not available, falls back to
text mode. TeX Live includes a Tcl/Tk runtime for Windows.
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 and
pdflatex sample2e. If that works, even
more useful is to try your real-life documents, to check that they still
work as expected. If third-party packages have changed incompatibly,
their maintainers should be contacted directly.
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.
Please email bug reports, suggestions, comments on TeX Live itself
(the installation process, tlmgr, etc.) to email@example.com (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.
Migrating from the pretest to the release
The last pretest build is usually close to the official release. If
you are using the standard directory setup, you can rename your pretest
installation (say, /usr/local/texlive/pretest) to the per-year
directory (/usr/local/texlive/2022) and change your search
path. The other change you will likely have to make is to take updates
from CTAN again: tlmgr option repo ctan.
Then, after the release is made, a normal update
(tlmgr update --self --all) should sync with
whatever changes were made after the last pretest. The result should be
equivalent to doing a full installation.
TeX Live documentation and translations are not
yet fully updated.
As always, there are pervasive updates to packages and programs.
We can't list them all, but here are the major user-visible changes in
the principal programs:
- New engine hitex, which
outputs its own HINT format, designed especially for reading technical
documents on mobile devices. HINT viewers for GNU/Linux, Windows, and
Android are also available.
- tangle, weave: support optional third argument to
specify output file.
- Knuth's program twill for making mini-indexes for original
WEB programs now included.
- Cross-engine extensions
- In engines except for original TeX, Aleph, and hiTeX:
- New primitive \showstream to redirect \show output to a file.
- New primitives \partokenname and \partokencontext allow overriding
the name of the \par token emitted at blank lines, the end of vboxes, etc.
- New primitives: \lastnodefont, \suppresslongerror,
- pdfTeX extension \vadjust pre now available.
- luatex (full LuaTeX news)

\pdfprependkern), still do protrusion; likewise, autokern
both implicit and explicit hyphens.
- ptex et al.
(full pTeX news)
- Major update of pTeX to 4.0.0 to better support current LaTeX.
- New primitives \ptexlineendmode and \toucs.
- \ucs (formerly available in uptex, euptex) becomes
available also in ptex, eptex.
- Distinguish 8-bit characters and Japanese characters
as discussed in a TUGboat
41:3 article by Hironori Kitagawa.
- Related changes in related engines:
uptex & euptex.
- xetex (full XeTeX news)
- New wrapper scripts xetex-unsafe and xelatex-unsafe
for simpler invocation of documents requiring both XeTeX and
PSTricks transparency operators, which is inherently unsafe (until
and unless reimplementation in Ghostscript happens). For safety, use
- dvipdfmx (full dvipdfmx news)
- Support for PSTricks without requiring -dNOSAFER, except
- The -r option to set bitmap font resolution works again.
- dvips (full dvips news)
- By default, do not attempt automatic media adjustment for rotated
paper sizes; the new option --landscaperotate re-enables.
- upmendex (full upmendex news)
- This index-sorting program is mostly upward-compatible with
makeindex, with much better
(Unicode-based) multilingual support. It's been in TL for some years.
- Experimental support for Arabic and Hebrew scripts; improved

- use https for mirror.ctan.org by
- use TEXMFROOT instead of SELFAUTOPARENT for easier relocating.
- MacTeX and its binary folder universal-darwin
require macOS 10.14 or higher (Mojave, Catalina, Big Sur, Monterey).
The x86_64-darwinlegacy binary folder, available only with the
Unix install-tl, supports 10.6 (Snow Leopard) and newer.
- No changes to platform support for this year (2022). However, for
next year's release (2023), we are planning to switch the Windows
binaries from 32-bit to 64-bit. Unfortunately we cannot feasibly support
If you discover other changes that should be noted, please report them.
Such documentation improvements are among the most important things
pretesters can help with.
