The release of the TeX Live 2021 distribution kit, created in 1996 on the basis of the teTeX project, has been prepared. TeX Live is the easiest way to deploy a scientific documentation infrastructure, regardless of the operating system used. A DVD assembly (4.4 GB) of TeX Live 2021 has been generated for download, which contains a working Live environment, a complete set of installation files for various operating systems, a copy of the CTAN (Comprehensive TeX Archive Network) repository, and a selection of documentation in different languages ββ(including Russian).
Among the innovations can be noted:
- TeX and Metafont include changes suggested by Donald Knuth to address some little-known issues with the handling of '\tracinglostchars' and '\tracingmacros'.
- In LuaTeX, the Lua interpreter has been updated to version 5.3.6.
- The SOURCE_DATE_EPOCH environment variable has been added to the MetaPost GUI interpreter to ensure repeatable builds.
- pdfTeX implements new "\pdfrunninglinkoff" and "\pdfrunninglinkon" primitives to disable link and footer generation. Dropped support for the poppler library - pdfTeX now always uses libs/xpdf.
- Dvipdfmx has Ghostscript's safe mode (dvipdfmx-unsafe.cfg) enabled by default
