We're strictly use version numbers of the form MAJOR.MINOR.PATCH.
Letter releases are things of days past.
The most central change is that we now express the version number with
three macros, one for each part of the version number:
OPENSSL_VERSION_MAJOR
OPENSSL_VERSION_MINOR
OPENSSL_VERSION_PATCH
We also provide two additional macros to express pre-release and build
metadata information (also specified in semantic versioning):
OPENSSL_VERSION_PRE_RELEASE
OPENSSL_VERSION_BUILD_METADATA
To get the library's idea of all those values, we introduce the
following functions:
unsigned int OPENSSL_version_major(void);
unsigned int OPENSSL_version_minor(void);
unsigned int OPENSSL_version_patch(void);
const char *OPENSSL_version_pre_release(void);
const char *OPENSSL_version_build_metadata(void);
Additionally, for shared library versioning (which is out of scope in
semantic versioning, but that we still need):
OPENSSL_SHLIB_VERSION
We also provide a macro that contains the release date. This is not
part of the version number, but is extra information that we want to
be able to display:
OPENSSL_RELEASE_DATE
Finally, also provide the following convenience functions:
const char *OPENSSL_version_text(void);
const char *OPENSSL_version_text_full(void);
The following macros and functions are deprecated, and while currently
existing for backward compatibility, they are expected to disappear:
OPENSSL_VERSION_NUMBER
OPENSSL_VERSION_TEXT
OPENSSL_VERSION
OpenSSL_version_num()
OpenSSL_version()
Also, this function is introduced to replace OpenSSL_version() for all
indexes except for OPENSSL_VERSION:
OPENSSL_info()
For configuration, the option 'newversion-only' is added to disable all
the macros and functions that are mentioned as deprecated above.

Rather than relying only on mandatory default digests, add a way for
the EVP_PKEY to individually report whether each digest algorithm is
supported.
