Of innovations you can note:

• In the search library Kpathsea improved handling of parenthesized expansion and file path splitting. Instead of a hard-wired "." added environment variable TEXMFDOTDIR, which allows you to control the coverage of subdirectories when searching;
• New primitives "\readpapersizespecial" and "\expanded" have been added to epTEX;
• LuaTEX has been updated to release Lua 5.3. To read PDF files, the own pplib library is involved, which made it possible to exclude the poppler library from dependencies;
• The r-mpost command has been added to MetaPost, similar to calling it with the "--restricted" option. The minimum precision for decimal and binary modes is set to 2. MPlib removed support for binary mode, which is left in MetaPost;
• A new primitive "\expanded" has been added to pdfTEX. When setting the "\pdfomitcharset" primitive to 1, the string "/CharSet" is not taken into account in the PDF output, since it cannot be guaranteed to be correct according to the PDF/A-2 and PDF/A-3 specifications;
• Added primitives "\expanded", "\creationdate", "\elapsedtime", "\filedump", "\filemoddate", "\filesize", "\resettimer", "\normaldeviate", "\uniformdeviate" and " \randomseed";

• Added "-gui" option to install-tl to launch new GUI on Tcl/Tk;
• The package is used as an implementation of the CWEB utility. cwebbin, which provides support for more dialects of the language;
