15  * @const IMG4_API_VERSION
16  * The API version of the library. This version will be changed in accordance
17  * with new API introductions so that callers may submit code to the build that
18  * adopts those new APIs before the APIs land by using the following pattern:
19  *
20  *     #if IMG4_API_VERSION >= 20180424
21  *     img4_new_api();
22  *     #endif
23  *
24  * In this example, the library maintainer and API adopter agree on an API
25  * version of 20180424 ahead of time for the introduction of
26  * img4_new_api(). When a libdarwin with that API version is submitted, the
27  * project is rebuilt, and the new API becomes active.
28  *
29  * Breaking API changes will be both covered under this mechanism as well as
30  * individual preprocessor macros in this header that declare new behavior as
31  * required.
32  *
33  * @note
34  * For a period of time, the API version was incorrectly defined as 20212105
35  * when it should have been 20210521. Avoid version comparisons across that
36  * version epoch.
