### Changes between 3.0 and 3.1 [xx XXX xxxx]
+ * Add support for TCP Fast Open (RFC7413) to macOS, Linux, and FreeBSD where
+ supported and enabled.
+
+ *Todd Short*
+
+ * Add ciphersuites based on DHE_PSK (RFC 4279) and ECDHE_PSK (RFC 5489)
+ to the list of ciphersuites providing Perfect Forward Secrecy as
+ required by SECLEVEL >= 3.
+
+ *Dmitry Belyavskiy, Nicola Tuveri*
+
+ * Add new SSL APIs to aid in efficiently implementing TLS/SSL fingerprinting. The
+ SSL_CTRL_GET_IANA_GROUPS control code, exposed as the SSL_get0_iana_groups()
+ function-like macro, retrieves the list of supported groups sent by the peer,
+ and the function SSL_client_hello_get_extension_order() populates a caller-supplied
+ array with the list of extension types present in the ClientHello, in order of
+ appearance.
+
+ *Phus Lu*
+
+ * Fixed PEM_write_bio_PKCS8PrivateKey() and PEM_write_bio_PKCS8PrivateKey_nid()
+ to make it possible to use empty passphrase strings.
+
+ *Darshan Sen*
+
+ * RNDR and RNDRRS support in provider functions to provide
+ random number generation for Arm CPUs (aarch64).
+
+ *Orr Toledano*
+
* s_client and s_server apps now explicitly say when the TLS version
does not include the renegotiation mechanism. This avoids confusion
between that scenario versus when the TLS version includes secure
*Felipe Gasper*
+ * AES-GCM enabled with AVX512 vAES and vPCLMULQDQ.
+
+ *Tomasz Kantecki, Andrey Matyukov*
+
* The default SSL/TLS security level has been changed from 1 to 2. RSA,
DSA and DH keys of 1024 bits and above and less than 2048 bits and ECC keys
of 160 bits and above and less than 224 bits were previously accepted by
*Sergey Kirillov, Andrey Matyukov (Intel Corp)*

+OpenSSL 3.0
+-----------
+
+For OpenSSL 3.0 a [Migration guide][] has been added, so the CHANGES entries
+listed here are only a brief description.
+The migration guide contains more detailed information related to new features,
+breaking changes, and mappings for the large list of deprecated functions.
+
+[Migration guide]: https://github.com/openssl/openssl/tree/master/doc/man7/migration_guide.pod
+
+### Changes between 3.0.2 and 3.0.3
+
+ * The functions `OPENSSL_LH_stats` and `OPENSSL_LH_stats_bio` now only report
+ the `num_items`, `num_nodes` and `num_alloc_nodes` statistics. All other
+ statistics are no longer supported. For compatibility, these statistics are
+ still listed in the output but are now always reported as zero.
+
+ *Hugo Landau*
+
+### Changes between 3.0.1 and 3.0.2 [15 mar 2022]
+
+ * Fixed a bug in the BN_mod_sqrt() function that can cause it to loop forever
+ for non-prime moduli.
+
+ Internally this function is used when parsing certificates that contain
+ elliptic curve public keys in compressed form or explicit elliptic curve
+ parameters with a base point encoded in compressed form.
+
+ It is possible to trigger the infinite loop by crafting a certificate that
+ has invalid explicit curve parameters.
+
+ Since certificate parsing happens prior to verification of the certificate
+ signature, any process that parses an externally supplied certificate may thus
+ be subject to a denial of service attack. The infinite loop can also be
+ reached when parsing crafted private keys as they can contain explicit
+ elliptic curve parameters.
+
+ Thus vulnerable situations include:
+
+ - TLS clients consuming server certificates
+ - TLS servers consuming client certificates
+ - Hosting providers taking certificates or private keys from customers
+ - Certificate authorities parsing certification requests from subscribers
+ - Anything else which parses ASN.1 elliptic curve parameters
+
+ Also any other applications that use the BN_mod_sqrt() where the attacker
+ can control the parameter values are vulnerable to this DoS issue.
+ ([CVE-2022-0778])
+
+ *Tomáš Mráz*
+
+ * Add ciphersuites based on DHE_PSK (RFC 4279) and ECDHE_PSK (RFC 5489)
+ to the list of ciphersuites providing Perfect Forward Secrecy as
+ required by SECLEVEL >= 3.
+
+ *Dmitry Belyavskiy, Nicola Tuveri*
+
+ * Made the AES constant time code for no-asm configurations
+ optional due to the resulting 95% performance degradation.
+ The AES constant time code can be enabled, for no assembly
+ builds, with: ./config no-asm -DOPENSSL_AES_CONST_TIME
+
+ *Paul Dale*
+
+ * Fixed PEM_write_bio_PKCS8PrivateKey() to make it possible to use empty
+ passphrase strings.
+
+ *Darshan Sen*
+
+ * The negative return value handling of the certificate verification callback
+ was reverted. The replacement is to set the verification retry state with
+ the SSL_set_retry_verify() function.
+
+ *Tomáš Mráz*
+
+### Changes between 3.0.0 and 3.0.1 [14 dec 2021]
+
+ * Fixed invalid handling of X509_verify_cert() internal errors in libssl
+ Internally libssl in OpenSSL calls X509_verify_cert() on the client side to
+ verify a certificate supplied by a server. That function may return a
+ negative return value to indicate an internal error (for example out of
+ memory). Such a negative return value is mishandled by OpenSSL and will cause
+ an IO function (such as SSL_connect() or SSL_do_handshake()) to not indicate
+ success and a subsequent call to SSL_get_error() to return the value
+ SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be
+ returned by OpenSSL if the application has previously called
+ SSL_CTX_set_cert_verify_callback(). Since most applications do not do this
+ the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be
+ totally unexpected and applications may not behave correctly as a result. The
+ exact behaviour will depend on the application but it could result in
+ crashes, infinite loops or other similar incorrect responses.
+
+ This issue is made more serious in combination with a separate bug in OpenSSL
+ 3.0 that will cause X509_verify_cert() to indicate an internal error when
+ processing a certificate chain. This will occur where a certificate does not
+ include the Subject Alternative Name extension but where a Certificate
+ Authority has enforced name constraints. This issue can occur even with valid
+ chains.
+ ([CVE-2021-4044])
+
+ *Matt Caswell*
* Corrected a few file name and file reference bugs in the build,
installation and setup scripts, which lead to installation verification
*Richard Levitte*
+ * Fixed EVP_PKEY_eq() to make it possible to use it with strictly private
+ keys.
