+Changelog for LyX-214-2:
 - fix bug that viewing/exporting of some file formats failed because of
   unknown executable for .py files
 - updated to Python 2.7.10 (fixes problems that LyX got erroneous if
   Python 2.7.10 was installed before LyX)
+- updated spell-checker dictionary for English (GB)
+  (To benefit from them you must uninstall an already installed LyX 2.1.x and
+   then use this installer.)
+- updated thesaurus for Slovenian
+  (you need to reinstall LyX to benefit from this)
