+- Update to 2.3.1:
+  Most important changes:
+  * Overhaul the document painting mechanism. Now the screen is updated
+    asyncronously (as all normal applications do), which makes LyX
+    snappier, especially on repeated events. As an added bonus, subpixel
+    aliasing is honored in the work area.
+  * All python scripts distributed with LyX should now be compatible with both
+    python 2.x and python 3.x.
+  * Native filedialogs
+  * TEX2LYX IMPROVEMENTS: support for biblatex, chapterbib, \includeonly,
+    and better quotationmark detection.
+  * For other improvements and bugfixes, see the included ANNOUNCE file.
+- Dropped fix-build-with-Qt5.11.patch, is part of this release
