-Due to the many reports we received, support for polyglossia, XeTeX's new
-language interface and babel replacement, has been added. In the same vein
-we added basic and experimental support for LuaTeX as well.
-
-Apart from these better support for sub/superscript has been added and
-externally launched documents are now possible to load in an already
-running LyX instance. Next changes has been done in context menu handling.
+Except usual bugfixing we addressed long-term slowness issues during this
+cycle, in particular we tried to improve performance of the following areas:
+* exporting of longer documents
+* editing of documents with rich inset structure
+* editing with opened outliner.
