This is an important year for the Macintosh because Apple introduced ARM machines in November and will sell and support both ARM and Intel machines for many years.The x86_64-darwinlegacy binary folder, available only with the Unix install-tl, supports 10.6 and newer. MacTeX and its new binary folder universal-darwin now require macOS 10.14 or higher (Mojave, Catalina, and Big Sur) the x86_64-darwin binary folder is no longer present.eps or other image file is not found, exit with bad status. Default PostScript document title is now the basename of the input file, and can be overridden with the new option -title.Support new feature of virtual font to fallback Japanese font definition.Experimental support for dviluatex’s extended fnt_def.Compatibility specials pdfcolorstack and pdffontattr.Extended special syntax for color support.If an image file is not found, exit with bad status.To use PSTricks with XeTeX, this is required, as in: xetex -output-driver=”xdvipdfmx -i dvipdfmx-unsafe.cfg -q -E” … Ghostscript is now invoked safely by default to override (assuming all input files are trusted), use -i dvipdfmx-unsafe.cfg.In native TL, pdfTeX has always used libs/xpdf, which is cut-down and adapted code from xpdf. Source: poppler support removed, as it was too hard to keep in sync with upstream.Dump \pdfglyphtounicode assignments in fmt file.Warn instead of aborting when “\pdfendlink ended up in different nesting level than \pdfstartlink”.New primitives \pdfrunninglinkoff and \pdfrunninglinkon e.g., for disabling generation of links in headers and footers.Value of epsilon changed in binary and decimal modes, so mp_solve_rising_cubic works as expected. Document -T option, other fixes to manual.SOURCE_DATE_EPOCH environment variable support for reproducible output.Removed width/ic compensation for traditional math code path.Mark math glyphs as protected to prevent processing as text.Callback for nesting level used in \tracingmacros, as generalized variant of the new \tracingstacklevels.The aleph binary itself is still included and supported. Aleph: The Aleph-based LaTeX format, named lamed, has been removed.Also, macro logging is truncated at a depth ≥ the parameter value. Except in original TeX: a new integer parameter \tracingstacklevels, if positive, and \tracingmacros is also positive, causes a prefix indicating the macro expansion depth to be output on each relevant log line (e.g., ~.Except in original TeX: if \tracinglostchars is set to 3 or more, missing characters will result in an error, not just a message in the log file, and the missing character code will be shown in hex.As expected, the fixes are for obscure cases and do not affect any behavior in practice. They are also available on CTAN as the knuth-dist and knuth-local packages. Donald Knuth’s changes for his 2021 tuneup of TeX and Metafont are incorporated ( ). Thanks goes to all the developers, builders, the great CTAN team, and everyone who has contributed to this release!įinally, here are the changes as listed in the master TeX Live documentation: Most of the above features have been available already either via tlpretest or via regular updates, but are now fully released on the DVD version.
