 ### Changes between 3.1.0 and 3.1.1 [30 May 2023]
 
+ * The `SSL_CERT_PATH` and `SSL_CERT_URI` environment variables are introduced.
+   `SSL_CERT_URI` can be used to specify a URI for a root certificate store. The
+   `SSL_CERT_PATH` environment variable specifies a delimiter-separated list of
+   paths which are searched for root certificates.
+
+   The existing `SSL_CERT_DIR` environment variable is deprecated.
+   `SSL_CERT_DIR` was previously used to specify either a delimiter-separated
+   list of paths or an URI, which is ambiguous. Setting `SSL_CERT_PATH` causes
+   `SSL_CERT_DIR` to be ignored for the purposes of determining root certificate
+   directories, and setting `SSL_CERT_URI` causes `SSL_CERT_DIR` to be ignored
+   for the purposes of determining root certificate stores.
+
+   *Hugo Landau*
+
+ * Support for loading root certificates from the Windows certificate store
+   has been added. The support is in the form of a store which recognises the
+   URI string of `org.openssl.winstore://`. This store is enabled by default and
+   can be disabled using the new compile-time option `no-winstore`.
+
+   *Hugo Landau*
+
  * Mitigate for the time it takes for `OBJ_obj2txt` to translate gigantic
    OBJECT IDENTIFIER sub-identifiers to canonical numeric text form.

+
+=head1 DESCRIPTION
+
+The X509_get_default_cert_file() function returns the default path
+to a file containing trusted CA certificates. OpenSSL will use this as
+the default path when it is asked to load trusted CA certificates
+from a file and no other path is specified. If the file exists, CA certificates
+are loaded from the file.
+
+The X509_get_default_cert_dir() function returns a default delimeter-separated
+list of paths to a directories containing trusted CA certificates named in the
+hashed format. OpenSSL will use this as the default list of paths when it is
+asked to load trusted CA certificates from a directory and no other path is
+specified. If a given directory in the list exists, OpenSSL attempts to lookup
+CA certificates in this directory by calculating a filename based on a hash of
+the certificate's subject name.
+
+The X509_get_default_cert_uri() function returns the default URI for a
+certificate store accessed programmatically via an OpenSSL provider. If there is
+no default store applicable to the system for which OpenSSL was compiled, this
+returns an empty string.
+
+X509_get_default_cert_file_env() and X509_get_default_cert_uri_env() return
+environment variable names which are recommended to specify nondefault values to
+be used instead of the values returned by X509_get_default_cert_file() and
+X509_get_default_cert_uri() respectively. The values returned by the latter
+functions are not affected by these environment variables; you must check for
+these environment variables yourself, using these functions to retrieve the
+correct environment variable names. If an environment variable is not set, the
+value returned by the corresponding function above should be used.
+
+X509_get_default_cert_path_env() returns the environment variable name which is
+recommended to specify a nondefault value to be used instead of the value
+returned by X509_get_default_cert_dir(). This environment variable supercedes
+the deprecated environment variable whose name is returned by
+X509_get_default_cert_dir_env(). This environment variable was deprecated as its
+contents can be interpreted ambiguously; see NOTES.
+
+By default, OpenSSL uses the path list specified in the environment variable
+whose name is returned by X509_get_default_cert_path_env() if it is set;
+otherwise, it uses the path list specified in the environment variable whose
+name is returned by X509_get_default_cert_dir_env() if it is set; otherwise, it
+uses the value returned by X509_get_default_cert_dir()).
+
+=head1 NOTES
+
+X509_get_default_cert_uri(), X509_get_default_cert_uri_env() and
+X509_get_default_cert_path_env() were introduced in OpenSSL 3.1. Prior to this
+release, store URIs were expressed via the environment variable returned by
+X509_get_default_cert_dir_env(); this environment variable could be used to
+specify either a list of directories or a store URI. This creates an ambiguity
+in which the environment variable returned by X509_get_default_cert_dir_env() is
+interpreted both as a list of directories and as a store URI.
+
+This usage and the environment variable returned by
+X509_get_default_cert_dir_env() are now deprecated; to specify a store URI, use
+the environment variable returned by X509_get_default_cert_uri_env(), and to
+specify a list of directories, use the environment variable returned by
+X509_get_default_cert_path_env().
+
+=head1 RETURN VALUES
+
+These functions return pointers to constant strings with static storage
+duration.
