+New external programs and libraries:
+------------------------------------
+
+LyX 2.0 introduces support for some new external helper programs/libraries,
+while the support for some existing programs has been dropped. This
+particularly applies to spell checking and the thesaurus.
+
+
+Known issues in version 2.0.0
+-----------------------------
+
+- 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 2.1.x
