#ifndef _CUPS_VERSIONING_H_

* This header defines several constants - _CUPS_DEPRECATED,
- * _CUPS_API_1_1, _CUPS_API_1_1_19, _CUPS_API_1_1_20, _CUPS_API_1_1_21,
- * _CUPS_API_1_2, _CUPS_API_1_3, _CUPS_API_1_4 - which add compiler-
- * specific attributes that flag functions that are deprecated or added
- * in particular releases. On Mac OS X, the _CUPS_API_* constants are
- * defined based on the value of the MAC_OS_X_VERSION_MAX_ALLOWED constant
+ * _CUPS_DEPRECATED_MSG, _CUPS_INTERNAL_MSG, _CUPS_API_major_minor, and
+ * _CUPS_API_major_minor_patch - which add compiler-specific attributes that
+ * flag functions that are deprecated, added in particular releases, or internal
+ * to CUPS.
+ *
+ * On macOS, the _CUPS_API_* constants are defined based on the values of
+ * the MAC_OS_X_VERSION_MIN_ALLOWED and MAC_OS_X_VERSION_MAX_ALLOWED constants
* provided by the compiler.
