mysteries of FTDNA's new public haplotree: 2018-11-02 tree for I-CTS11338

Click here to download our 2018-11-02 tree for I-CTS11338

This tree shows a new Big Y for a man with ancestry from the 1600s from New Hampshire, USA. He is CTS787+ and he also Y4389+ and Y4386+/Z27251+, these SNPs have been considered equivalent to CTS787. And he is ancestral for Z99, Z128, Z125 and many other SNPs that previously were considered equivalent CTS787.

FTDNA's haplotree currently shows Y4389 and Y4386/Z27251 as equivalent to Z99, Z128, Z125 etc. But I think FTDNA will update their tree soon to show the information from this new Big Y.

But FTDNA's haplotree already shows that CTS787 is the only SNP in its level, and Y4389, Y4386/Z27251, Z99, Z128, Z125 etc. are at a lower level. I don't know how to find older versions of FTDNA's haplotree, so I don't know when FTDNA made this change. FTDNA has a new public haplotree (click here) but I can't find information about any CTS787+ but Y4389- Y4386-/Z27251- samples.
