You have to read the NEWS file.

There was a change between GNU make 3.80 and 3.81.  In 3.80, the System
V make feature that expands $@ (and only $@) twice in the prerequisites
list was automatically on, all the time.

Starting in 3.81, the much more general secondary expansion feature is
available, which is a superset of, and subsumes, that feature, but ONLY
when the .SECONDEXPANSION target is set.
