-- some summary about 3rd party programs additions/removals should be

+Changes with respect to external programs and libraries in 2.2:
+--------------------------------------------------------
+
+
+- LyX is not yet supposed to work with Qt5. It is advised to compile and
+ run LyX against Qt 4.8.x. On Windows, Qt 4.8.5 suffers from a bug that
+ breaks the use of shortcuts, so on Windows Qt 4.8.4 is advised.
+
+
+Known issues in version 2.2.0
+-----------------------------
+
+- LyX needs to be run under Python 2 and will not work properly on systems
+ where Python 3 is the default binary. See bug #7030 to know how to fix
+ this properly, since simple sheebang conversion in *.py files will not
+ be enough.
+
+
+Caveats when upgrading from earlier versions to 2.2.x
