Incompatible API changes
From Apache OpenOffice Wiki
This page gives an overview about incompatible changes of API's as well configuration data or other relevant data that can have influence on existing macros and/or extensions. The goal is that besides the pure documentation of the change a possible migration path for developers should be documented and should help during the migration to adapt the change in own macros or own extensions. A collaboration of core developers together with macro/extension developers is important for the eco-system around OpenOffice.
