6/* This number represents Ruby's ABI version.
7 *
8 * In development Ruby, it should be bumped every time an ABI incompatible
9 * change is introduced. This will force other developers to rebuild extension
10 * gems.
11 *
12 * The following cases are considered as ABI incompatible changes:
13 * - Changing any data structures.
14 * - Changing macros or inline functions causing a change in behavior.
15 * - Deprecating or removing function declarations.
16 *
17 * The following cases are NOT considered as ABI incompatible changes:
18 * - Any changes that does not involve the header files in the `include`
19 * directory.
20 * - Adding macros, inline functions, or function declarations.
21 * - Backwards compatible refactors.
22 * - Editing comments.
23 *
24 * In released versions of Ruby, this number is not defined since teeny
25 * versions of Ruby should guarantee ABI compatibility.
