[tex-live] BibLatex issues after last upgrade

This morning I did a TL-2015 upgrade but some documents do not build any 
more. For example:

$ latexmk -pdf solutio_majorana
! Undefined control sequence.
l.1597 \ifblx at load@version at one


? h
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.


Notice the same document built fine with TL-2015 upgrade I did on March
