-The support for Japanese has been improved in LyX 1.6.x. Due to encoding
-reasons, Japanese documents that were edited with LyX 1.6.x cannot correctly
-be converted to the format of LyX 1.5.x and thus not edited with LyX 1.5.x.
-To be able to use LyX 1.6 with Japanese, the latest version of the LaTeX
-distribution "platex" must be installed.
-platex provides a Japanese variant of BibTeX named "jbibtex". When LyX is
-configured, this variant is used. In case you have problems with BibTeX-files
-that include Japanese or you need to use another BibTeX program, set it in LyX
-preferences under Output->LaTeX->BibTeX command.
+- The syntax of the languages file has been changed. If you use a modified
+ languages file, you will need to adapt it to the new syntax, as LyX 2.0
+ is not able to read old languages file anymore.
+ Please refer to the beginning of the languages file for an explanation
+ of the new syntax.
