/* 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 should not be changed since teeny
|
|
* versions of Ruby should guarantee ABI compatibility.
