New Features in MacTeX-2024 and TeX Live 2024

MacTeX-2024

Since 2021, MacTeX has supported both Arm and Intel processors. Arm binaries are compiled on a machine with an Arm processor and Intel binaries are compiled on a machine with an Intel processor. Then these binaries are combined into a single "universal binary" file.

The program TeX Live Utility by Adam Maxwell makes heavy use of the scripting language Python. Python has been included in macOS for many years, but recently Python 2 was replaced by Python 3 and it became harder to predict which version would be in macOS. So Apple told developers that Python would eventually be removed from macOS and if they use it, they should embed a copy directly in their applications. TeX Live Utility now contains its own copy of Python. Apple indeed removed Python from the third update of Monterey, but TeX Live Utility continued to work.

The GUI-Applications portion of MacTeX-2024 installs hintView, a small application by Martin Ruckert which allows users to get a feel for his Hint project. TeX Live 2024 contains Ruckert's programs hitex and hilatex, which convert TeX source files into hnt files rather than pdf files. These hnt files contains "hints" for reflowing the text, so suitable viewers on iPads, iPhones, and similar devices could display documents for reading on these devices, and allow users to magnify and reflow the text.

TeX Live 2024

The following list of TeX Live changes is taken directly from a TUG pretest web page. The TUG page has relative links into the documentation which we removed. Read below for a brief overview. For details, go to https://tug.org.

Notable changes

As always, there are pervasive updates to packages and programs. We can't list them all, but here are the major user-visible changes in the principal programs relative to initial TL23 release:

luatex

metapost
The MPFI library now included for interval arithmetic; enabled with --numbersystem=interval.

pdftex

(e)(u)ptex

xetex
Only Kpathsea and other cross-engine updates.

cweb

dvipdfmx

kpathsea

tlmgr

MacTeX
MacTeX-2024 contains the latest Chostscript 10.03.0, updates of all four GUI programs, along with (as always) all new TL changes. The binaries still support macOS 10.14 (Mojave) and later. (As usual, earlier Mac versions are supported by the x86_64-darwinlegacy binaries, which are part of TL, but not MacTeX.)

If you discover other changes that should be noted, please report them. Such documentation improvements are useful to many people.



Happy TeXing on macOS !
