-Public release of LyX version 2.4.4
+Public release of LyX version 2.4.5
===================================
-We are proud to announce the release LyX 2.4.4, the fourth maintenance
+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, and introduced a few new features.
+crashes.
-Here are some highlights.
+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.
-There have been a number of updates to LyX's interface with computer algebra
-systems. See below for details.
+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.
-LyX now (again) has a function (error-next) and a menu entry (Navigate >
-Next Error) to quickly jump to the next compilation error. This re-introduces
-a feature we lost 20 years ago with LyX 1.4 (bug 2775)! LyX now also has a
-function (errors-show) and a menu entry (Document > Processing Errors) to
-(re)open the dialog that lists compilation errors (a.k.a. "LaTeX Errors")
-after it has been closed, with the next error at/after cursor highlighted.
+For complete information on what's new and on bugs that have been fixed,
+see the list below.
-One important fix concerns the generation of previews. In certain cases,
-LaTeX adds a temporary page at the end, and this confuses our python script
-that generates previews, making it unable to determine the pages to process
-through dvipng. This requires a re-run of LaTeX, which we can easily do. See:
-https://tex.stackexchange.com/questions/689978/why-does-temporary-page-error-occur
-A related problem has been solved for dvipng versions >= 1.16. With earlier
-versions, dvipng returns with an error code when some previews contain
-postscript specials, so that LyX will 'fall back' to the legacy method for
-generating all previews instead of only the ones with postscript specials.
-These will be of lower quality, and various messages will be output to the
-terminal. If this bothers you, please upgrade your version of dvipng.

-- LyX includes a new icon set to select from in preferences: Adwaita. This is
