I believe it's a separate patch rather than continuation of the same maintenance, or fix for a fix.
There's an issue in Forked Tower fourth boss where German and French language players aren't able to distinguish between 2 attacks due to the names being the same in those languages. There's a fix coming in this that looks to correct naming of those attacks for those players - it's mentioned in the notes.
Also some mention of additional fixes expected in the upcoming Live Letter.
It was likely planned this way as the previous maintenance was for mostly infrastructure.
As much as XIV is the MMO I enjoy the most of the two, I absolutely agree with this. I would have much preferred XI mobile.
