DESCRIPTION
OPENSSL_VERSION_NUMBER and LIBRESSL_VERSION_NUMBER are numeric release version
identifiers. The first two digits contain the major release number, the third and
fourth digits the minor release number, and the fifth and sixth digits the fix re‐
lease number. For OpenSSL, the seventh and eight digits contain the patch release
number and the final digit is 0 for development, 1 to e for betas 1 to 14, or f
for release. For LibreSSL, OPENSSL_VERSION_NUMBER is always 0x020000000, and
LIBRESSL_VERSION_NUMBER always ends with 00f.
