This is mostly a PSA so when we get 17.2 in 2030 we can ask the studio for the update

Google translates this as...

The cards that were added are the cards from dungeons/zones added after 17.1 up to 17.2 (included)
This makes me think that there was another OCA and potentially MCA update before this one. I remember a few years back we asked kRO for an OCA update and they said we were up to date, that doesnt seem to be the case anymore, we still dont have the content in this new update but like i just said i think is really likely they updated it before
I couldnt find any info about a previous update but i didnt searched thoroughly
