- * So, here's the way it works here: first of all, the library version
- * number doesn't need at all to match the overall OpenSSL version.
- * However, it's nice and more understandable if it actually does.
- * The current library version is stored in the macro SHLIB_VERSION_NUMBER,
- * which is just a piece of text in the format "M.m.e" (Major, minor, edit).
- * For the sake of Tru64, IRIX, and any other OS that behaves in similar ways,
- * we need to keep a history of version numbers, which is done in the
- * macro SHLIB_VERSION_HISTORY. The numbers are separated by colons and
- * should only keep the versions that are binary compatible with the current.
+ * This is strictly to express ABI version, which may or may not
+ * be related to the API version expressed with the macros above.
+ * This is defined in free form.
