# Before a release perform the following checks against the last release:
# * If a function has been removed or the paramaters of a function have changed
#   bump SOMAJOR and set SOMINOR to 0.
# * If any of the exported datastructures have changed in a incompatible way
#   bump SOMAJOR and set SOMINOR to 0.
# * If a function has been added bump SOMINOR.
