/* This number represents Ruby's ABI version.
*
* In development Ruby, it should be bumped every time an ABI incompatible
* change is introduced. This will force other developers to rebuild extension
* gems.
*
* The following cases are considered as ABI incompatible changes:
* - Changing any data structures.
* - Changing macros or inline functions causing a change in behavior.
* - Deprecating or removing function declarations.
*
* The following cases are NOT considered as ABI incompatible changes:
* - Any changes that does not involve the header files in the `include`
* directory.
* - Adding macros, inline functions, or function declarations.
* - Backwards compatible refactors.
* - Editing comments.
*
* In released versions of Ruby, this number is not defined since teeny
* versions of Ruby should guarantee ABI compatibility.
