If you have reached the threshold, the language will be included with MediaWiki starting from today. It should reach Wikimedia wikis this week and be included in the next MediaWiki release in about six months.
Right now it looks like the threshold for automatic export was not reached yet. I will encourage you to continue adding translations and soon it will be including in MediaWiki.
I don't understand. This page lists kabiye as now having 96% of the messages translated, and 4% obsolete:
And the list on this page (messages left to translate) is empty:
So what is there left to do?
Right now the threshold for automatic export is 18% of MediaWiki core: https://translatewiki.net/w/i.php?title=Special:MessageGroupStats&group=core#sortable:3=asc
Now I realize that earlier you could have reached 18% by translating most used messages. I will attempt to make the threshold lower to match the intention.
It would be great if you could translate some additional MediaWiki core messages – there are simple ones available to quickly get you there.
If you are interested in the details, I wrote some in https://gerrit.wikimedia.org/r/#/c/291231/
Please accept my apologies for the delays and changing requirements. This should be the final request from me.
