Changing Japanese namespace names of MediaWiki

Just review all MediaWiki core translations and look them up. That's probably the most elaborate way, as I expect there is more than one occurrence. Btw, the changes have been deployed as far as I know.

MediaWiki:Talk/ja, MediaWiki:Talkpagelinktext/ja, MediaWiki:Vector-namespace-talk/ja have been changed. Other messages?

You should check all messages containing namespace names as text. Messages like Nstab-category (“Category”) and the ones for other namespaces.

Now no message contains "ノート" in MediaWiki core, except Exif-makernote (“Manufacturer notes”).

But "ノート" is still used on page tab label (c.f. [1]). Why?

See FAQ, item 1.

Thanks, it's corrected!
