That was only a minor update from the icu-55.1 release candidate to the
final release, hardly affecting XeTeX.

Certainly not, but XeTeX uses HarfBuzz for layout and some ICU libraries
(not the layout library libicule) for general Unicode things (and
libharfbuzz also uses libicuuc).

ICU with the layout library libicule and without HarfBuzz was last used for
TL'12.
