There is no difference except for the name of the command.

Freeze/thaw is new functionality as of BIND 9.3.0. We
changed unfreeze to thaw because we didn't like unfreeze.
Yes this was a change very late in the development phase
but it was still in the development phase. BIND 9.3 has
now shifted to the maintenance phase.

You should fix your scripts because there is no guarantee
that unfreeze will be supported as deprecated in BIND 9.4.0.
That way when you upgrade to BIND 9.4.0 they will be less
work.
