Another new function in libapi that I didn't see in the changelog is
"get_spell_provider". With this function a spell can know which provider
was used for a certain dependency. This is of interest for spells that
need different options for different providers, e.g. galeon2
The current galeon2 spell uses the following to determine options:
if spell_ok mozilla; then
   OPTS="$OPTS --with-mozilla=mozilla"
else
   OPTS="$OPTS --with-mozilla=firefox"
fi &&

With the new function this would look like:
if test $(get_spell_provider $SPELL GECKO) == "firefox"; then
  OPTS="$OPTS --with-mozilla=firefox"
else
  OPTS="$OPTS --with-mozilla=mozilla"
fi

The advantage of this is that the choice the user makes for the provider
actually gets used if he has both mozilla and firefox installed.
mozilla/firefox is an obvious example for the usage of this function as
there are now several apps that can be built against both, but I'm sure
there are other providers for which this is useful too.
