# 1. If the library source code has changed at all since the last update, then increment revision
# 2. If any interfaces have been added, removed, or changed since the last update, increment current and set revision to 0.
# 3. If any interfaces have been added since the last public release, then increment age.
# 4. If any interfaces have been removed since the last public release, then set age to 0.
