+PART II - Translation of Math environments and Floats in the final output
+-------------------------------------------------------------------------
+
+As of 2.0 LyX allows automatic translation in tex/dvi/ps/pdf output for math
+environment strings (and some floats) which are not automatically translated via
+babel package to the localized form. For example the environment "Exercise"
+becomes "Aufgabe" in the output of the documents with language set to German.
+
+These translations are taken from the previously translated .po file before the
+final major LyX release (e.g. 2.0.0) and are fixed for all next minor releases
+(e.g. 2.0.x) in order to have fixed output of LyX documents.
