+Public release of LyX version 2.3.4-3
+=====================================
+
+This is another emergency release that, hopefully, actually fixes the
+first bug that 2.3.4-2 was meant to fix: A delay when saving files on
+Windows. The new bug is #11737. There are no other changes. Only Windows
+users will need to upgrade to this version.
