Unlike regular word processors that use the wysiwyg principle, LyX uses wysiwym. More information about LyX can be found on this page are being found. Version 2.3.1 has been released and the announcement looks like this:

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 now 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 of 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.
