MODULE_ABI_VERSION

The version of the module system's ABI.

Modules put this value into ModuleInfo's abi_version field so the code loading the modules can check if it was compiled against the same module ABI the modules are compiled against.

GIMP_MODULE_ABI_VERSION is incremented each time one of the following changes:

• the libgimpmodule implementation (if the change affects modules).
• one of the classes implemented by modules (currently GimpColorDisplay, GimpColorSelector and GimpController).
