the release of the distribution , created in 1996 based on the teTeX project. TeX Live is the easiest way to deploy infrastructure for preparing scientific documentation, regardless of the operating system used. To download DVD assembly (3.5 GB) TeX Live 2020, 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 collection of documentation in various languages (including Russian).
From notable mentions include:
- The ability to use group separators ({…}) in all TeX engines to specify the names of addition files in the \input primitive (previously, such separators were only supported in LuaTeX).
- In kpsewhich, tex, mf, and all other engines, the option "—cnf-line" has been added to pass arbitrary settings in the command line.
- New primitives \Uchar, \Ucharcat, \current(x)spacingmode, \ifincsname have been implemented in epTeX and eupTeX.
- In LuaTeX, the HarfBuzz library has been integrated, available in the form of new engines luahbtex and luajithbtex. New primitives \eTeXgluestretchorder and \eTeXglueshrinkorder have been added.
- In pdfTeX, a new primitive \pdfmajorversion has been added. The ability to search for images using the \pdfximage primitive, which works analogously to \openin, has been implemented.
- In pTeX, epTeX, upTeX, eupTeX, new primitives \ifjfont and \iftfont have been implemented.
- Dvips ensures output encoding for raster fonts.
- In MacTeX for versions up to 10.13 (High Sierra, Mojave, Catalina), the minimum requirements for macOS version have increased. For x86_64-darwinlegacy, support for versions 10.6+ has been provided.
- An automatic retry attempt is provided in case of package download failure.
- A command "tlmgr check texmfdbs" has been added to check the correctness of the ls-R files and the specifications "!!".
- Versioned placement of file names in packages (tlnet/archive/pkgname.rNNN.tar.xz) has been ensured, simplifying their use in distributions.
