We're pleased to announce that concrete5.5.1 has been released!

concrete5.5.1.ja Release Note (in Japanese)
http://concrete5-japan.org/news/concrete5-5-1-release/...

We've found and fixed all kinds of internationalization problem on the main core.
Unfortunately we still needed to modify the core, and had to be repeased separately.

If you happened to get into some internationalization problem, espcially multibyte language developper and users. You can "diff" between our package and main package to check what we modified.

We cannot list all parts since the list is still long.

Upon this release, over dozen concrete5 Japan members have worked on the translation and modification.
