-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.
-
-Smaller changes to be highlighted are:
-* better support for sub/superscripts
-* externally launched documents are now possible to load in an already
- running LyX instance
-* TikZ and PSTricks support in instant preview insets
-* 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.
