# The string is of the form C:R:A.

# - If interfaces have been changed or added, but binary compatibility

# has

#   been preserved, change to C+1:0:A+1

# - If binary compatibility has been broken (eg removed or changed

# interfaces)

#   change to C+1:0:0

# - If the interface is the same as the previous version, change to

# C:R+1:A
