Public release of LyX version 2.4.5
===================================

We are proud to announce the release LyX 2.4.5, the final maintenance
release in the 2.4.x series. We have fixed a number of bugs, including some
crashes.

Most of the development effort since 2.4.4 has been focused on LyX 2.5.0,
however, and most users will want to upgrade to that version. This version
is intended primarily for users who need, for some reason, to continue with
LyX 2.4.x. However, LyX 2.4.5 is able to import files created with LyX
2.5.x and to export to that format. Please note, however, that going back
and forth between major versions is not recommended.

The import and export capability of files in the 2.5.x format requires a
higher minimum python than previous releases in the 2.4.x series. The minimum
python version is now python 3.6.0 instead of python 2.7.0 or 3.5.0.

One big improvement is that one can now include the symbols system file from
the corresponding file in the user directory by using "include_system_file".
This will be equivalent to inserting the system symbols file at that point.

For complete information on what's new and on bugs that have been fixed,
see the list below.

You can download LyX 2.4.5 from http://ftp.lyx.org/pub/lyx/stable/2.4.x/
and pre-compiled binaries from http://ftp.lyx.org/pub/lyx/bin/2.4.5/.

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).

What's new
==========

** Updates:
***********

* DOCUMENT INPUT/OUTPUT

- Correctly parse labels enclosed in braces in mathed (bug 13195).


* MISCELLANEOUS

- It is now possible to include the symbols system file from the corresponding
  file in the user directory by means of the directive "include_system_file".
  This will be equivalent to inserting the system symbols file at that point.
  The symbols file is used in mathed and now it is possible to perform own
  additions/modifications without the need of making a copy in the user dir.


* LYX2LYX

- Import and export LyX 2.5.x documents.


* USER INTERFACE
