Software update: LyX 2.3.1




LyX is an open source and cross platform system with which documents can be created. In short, it is a graphical user interface for TeX and LaTeX . It is mainly used in the academic world because it can easily formulate formulas and show an overview of the document structure. Unlike regular word processors using the wysiwyg principle, LyX uses wysiwym . More information about LyX can be found on this page . Version 2.3.1 has been released and the announcement of it is as follows:

Public release of LyX version 2.3.1

We are proud to announce the release of LyX 2.3.1. This is the first maintenance release in the 2.3.x series. LyX 2.3.1 is the result of on-going efforts to make our stable version more reliable and more stable. We have fixed a number of bugs and added some new features. Please see below for a full list. Perhaps the most important of these is that Jean-Marc Lasgouttes re-wrote the document painting mechanism. This makes LyX snappier, especially on repeated events.

All python scripts distributed with LyX should be compatible with both python 2.x and python 3.x.

One oft-requested enhancement was to restore a keyboard shortcut for opening the ‘settings’ menu or graphics, reference, etc, insets. This is now Control-Alt-i, on Windows and Linux, and Control-Option-i on OSX (assuming you are using the default keybindings).

A change to how math macros are output can break some documents that use ERT to comment out macros. Please see bug # 11216 if you experience this sort of problem.

If you have a bug in LyX 2.3.1, please open a bug report at If you’re not sure if it’s a bug, you can email the LyX developers’ mailing list (lyx-devel and ask.
