This happens quite often.
It can be because more meaningful commands, or more compliant to the
standard are found,
or commands more consistent with the rest of the syntax.
for instance look at slow query log parameter change
Usually not to create problems alias are introduced for quite long time and
then only at a certain point (very late) made obsolete.
You may read the Release Notes of the release you are using, and/or the
previous ones, to know what changes have been done.
In any case it shouldn't represent any problem.
