Public release of LyX version 2.4.2
===================================

We are proud to announce the release LyX 2.4.2, the second maintenance
release in the 2.4.x series.



There has been a change (as of 2.4.0) in how the option to use vertical
space between paragraphs is handled. Previously, LyX simply modified 
\parskip and \parindent, but this caused various problems (see bug 
#4796). Now, we use the parskip package. As a result, however, and
to ensure there are no changes to old documents, when LyX files from 
2.3.x and earlier are converted to the new format, if they were set to
use vertical space between paragraphs, the lyx2lyx conversion routine
adds 
  % Added by lyx2lyx
  \setlength{\parskip}{\smallskipamount}
  \setlength{\parindent}{0pt}
to the preamble and, within LyX itself, resets the text layout to use
indentation (so we do not issue the new code for vertical spacing). The
net effect is that PDFs generated with LaTeX (etc) look right, but in
LyX itself indentation is used. 

This will happen with any document created with 2.3.x or older. It can
also happen with documents created from templates created with 2.3.x 
or older, and even with new documents, if you had previously set them to 
use, by default, vertical space. Templates are just LyX files saved in 
the templates/ folder, and the 'defaults' are simply saved in a
template file, defaults.lyx. Hence, if you want the new behavior, or 
just want the LyX document to look `right', then you will need to make
two changes to the document or template: Remove what lyx2lyx added, and
then set Paragraph Separation to Vertical Space.

If you have trouble using LyX or have a question, consult the
documentation that comes with LyX (under Help) and the LyX wiki, which you
will find at https://wiki.lyx.org/. You can also send email to the LyX users'
list (lyx-users at lists.lyx.org). Bugs can be reported on our bug tracker
(https://www.lyx.org/trac/) or by writing the developers' list (lyx-devel at
lists.lyx.org).
