Changing Japanese namespace names of MediaWiki

We're changing "ノート" to "トーク" in all MediaWiki translation now, and completed MediaWiki core and Extentions used by Wikimedia .

But on page tab label, "ノート" is still in use. How (What message) should we change?

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!
