So far, with the information we have, Yachiru's history section is upto date and current. No doubt when more revelations are uncovered it will become out of date but the information there follows Yachiru's own narrated history from Chapter 114 and it is referenced as such. No changes should be made until we know exactly what changes we are making. At one point the scan chapters had many users thinking that Kyōkotsu was Nanao's Zanpakuto and we know this turned out to be untrue and elaborated on in the next Chapter.

With special cases like this accuracy is everything and we need to be patient for that accuracy and elaboration. Thanks for being interested in helping out though.
