# When doing a release, they should be updated like this:
# 1. If no interfaces changed, only implementations: just increment
# revision.
# 2. If interfaces were added, none removed: increment current, set
# revision to zero and increment age.
# 3. If interfaces were removed (breaks backward compatibility): increment
# current, and set both revision and age to zero.
