From notable mentions include:
- In the search library improved handling of bracket operations and file path separation. Instead of a hardcoded character '.', an environment variable TEXMFDOTDIR has been added to manage the scope of subdirectory searches;
- New primitives '\readpapersizespecial' and '\expanded' have been added to epTEX;
- LuaTEX has been updated to Lua 5.3. A proprietary library, pplib, has been employed for reading PDF files, allowing the removal of the poppler library from the dependencies;
- A command r-mpost has been added to MetaPost, analogous to the call with the '—restricted' option. The minimum precision for decimal and binary modes is set to 2. Support for binary mode has been removed from MPlib, which is retained in MetaPost;
- A new primitive '\expanded' has been added to pdfTEX. When the primitive '\pdfomitcharset' is set to 1, the string '/CharSet' is ignored in the PDF output, as its correctness cannot be guaranteed according to the specifications PDF/A-2 and PDF/A-3;
- New primitives have been added to XeTEX: '\expanded', '\creationdate', '\elapsedtime', '\filedump', '\filemoddate', '\filesize', '\resettimer', '\normaldeviate', '\uniformdeviate', and '\randomseed';

- The install-tl now includes the option '-gui', which allows launching a new graphical interface in Tcl/Tk;
