it does a:

+#if !LIBGIT2_VER_MAJOR && LIBGIT2_VER_MINOR > 20
  git_libgit2_init();
+#else
+ git_threads_init();
 #endif

and the only sense behind that is - 799e22ea (API broken) is after
4fb32a44 (version.h bumped to 0.21).
they are not using the revision digit in master when breaking the API
so there is no way to figure out when the change happened.

also the version bump for 0.21 is not at the tag for 0.21, but before it.
