TeX Live 2020 - bugs and updates
Most of TeX Live is a redistribution of
packages and programs from elsewhere, primarily CTAN. So, the target for bug reports varies
according to the nature of the problem.
- If you have problems with a TeX document, e.g., a package is no
longer behaving as it used to, report it to the package maintainer. As a
rule, package-specific fixes are not installed directly in TL; instead,
new versions of packages should be uploaded to CTAN.
- If you have questions about using TeX, or need help with TeX, please
use the general help resources.
- To report a bug in TeX Live installation or infrastructure, email
the public mailing list
- For security-related reports, please use the email@example.com mailing
list (private archives).
If you need to use alternate binaries, our recommended approach is the custom binary support in the TL installer.
For information on 64-bit Windows binaries, see the Windows on TeX Live page.
Bug archives for the
previous release and earlier years remain
online (under systems/texlive; both the initial release each year, and
the frozen state at the end of the cycle in tlnet-final).
As always, there were pervasive updates to packages and programs.
We can't list them all, but here are some major user-visible changes in
the principal programs:
- The \input primitive in all TeX engines, including
tex, now also accepts a group-delimited filename argument, as a
system-dependent extension. The usage with a standard
space/token-delimited filename is completely unchanged. The
group-delimited argument was previously implemented in LuaTeX; now it
is available in all engines. ASCII double quote characters (")
are removed from the filename, but it is otherwise left unchanged after
tokenization. This does not currently affect LaTeX's \input command,
as that is a macro redefinition of the standard \input primitive.
- New option --cnf-line for kpsewhich, tex,
mf, and all other engines, to support arbitrary configuration
settings on the command line.
- The addition of various primitives to various engines in this and
previous years is intended to result in a common set of functionality
available across all engines (LaTeX News #31.
- Nothing major other than the above; see full Kpathsea news for details.
- New primitives \Uchar, \Ucharcat,
revise \fontchar?? and \iffontchar. For euptex
- luatex (full LuaTeX news)
- Integration with HarfBuzz library, as new engines luahbtex
and luajithbtex; luahbtex is now the engine used
for the lualatex format and executable.
- Loading of dso (.dll/.so) objects forbidden if --shell-restricted.
- New primitives \eTeXglue[stretch|shrink]order.
- Scaling of virtual fonts supported.
- Enhancements to tex.runtoks, which permits limited nested
running of TeX.
- Nothing major; see full MetaPost news for details.
- pdftex (full pdfTeX news)
- New primitive \pdfmajorversion; this merely changes the version
number in the PDF output; it has no effect on PDF content.
- \pdfximage and similar now search for image files in the
same way as \openin.
(full pTeX news)
- New primitives \ifjfont, \iftfont. Also in eptex,
uptex, and euptex.
- xetex (full XeTeX news)
- Fixes for \Umathchardef,
- dvips (full dvips news)
- Output encodings
for bitmap fonts, for better copy/paste capability.
- tlmgr (full tlmgr news)
- Automatically retry (once) packages that fail to download.
- New option tlmgr check texmfdbs, to check consistency of
ls-R files and !! specifications for each tree.
- Use versioned filenames for the package containers, as in
tlnet/archive/pkgname.rNNN.tar.xz; should be
invisible to users, but a notable change in distribution.
- catalogue-date information no longer propagated from the
TeX Catalogue, since it was often unrelated to package updates.
- MacTeX and x86_64-darwin now require macOS 10.13 or higher
(High Sierra, Mojave, and Catalina); x86_64-darwinlegacy supports
10.6 and newer. MacTeX is notarized and command line programs have
hardened runtimes, as now required by Apple for install packages.
BibDesk and TeX Live Utility are not in MacTeX because they are not
notarized, but a README file lists urls where they can be obtained.
