+OpenSSL 3.4
+-----------
+
+### Major changes between OpenSSL 3.3 and OpenSSL 3.4 [under development]
+
+OpenSSL 3.4.0 is a feature release adding significant new functionality to
+OpenSSL.
+
+This release is in development.
+
+OpenSSL 3.3
+-----------
+
+### Major changes between OpenSSL 3.2 and OpenSSL 3.3 [under development]
+
+OpenSSL 3.3.0 is a feature release adding significant new functionality to
+OpenSSL.
+
+This release adds the following new features:
+
+ * Support for qlog for tracing QUIC connections has been added
+
+ * Added APIs to allow configuring the negotiated idle timeout for QUIC
+ connections, and to allow determining the number of additional streams
+ that can currently be created for a QUIC connection.
+
+ * Added APIs to allow disabling implicit QUIC event processing for QUIC SSL
+ objects
+
+ * Added APIs to allow querying the size and utilisation of a QUIC stream's
+ write buffer
+
+ * New API `SSL_write_ex2`, which can be used to send an end-of-stream (FIN)
+ condition in an optimised way when using QUIC.
+
+ * Limited support for polling of QUIC connection and stream objects in a
+ non-blocking manner.
+
+ * Added a new EVP_DigestSqueeze() API. This allows SHAKE to squeeze multiple
+ times with different output sizes.
+
+ * Added exporter for CMake on Unix and Windows, alongside the pkg-config
+ exporter.
+
+ * The BLAKE2s hash algorithm matches BLAKE2b's support for configurable
+ output length.
+
+ * The EVP_PKEY_fromdata function has been augmented to allow for the
+ derivation of CRT (Chinese Remainder Theorem) parameters when requested
+
+ * Added API functions SSL_SESSION_get_time_ex(), SSL_SESSION_set_time_ex()
+ using time_t which is Y2038 safe on 32 bit systems when 64 bit time
+ is enabled
+
+ * Unknown entries in TLS SignatureAlgorithms, ClientSignatureAlgorithms
+ config options and the respective calls to SSL[_CTX]_set1_sigalgs() and
+ SSL[_CTX]_set1_client_sigalgs() that start with `?` character are
+ ignored and the configuration will still be used.
+
+ * Added `-set_issuer` and `-set_subject` options to `openssl x509` to
+ override the Issuer and Subject when creating a certificate. The `-subj`
+ option now is an alias for `-set_subject`.
+
+ * Added several new features of CMPv3 defined in RFC 9480 and RFC 9483
+
+ * New option `SSL_OP_PREFER_NO_DHE_KEX`, which allows configuring a TLS1.3
+ server to prefer session resumption using PSK-only key exchange over PSK
+ with DHE, if both are available.
+
+ * New atexit configuration switch, which controls whether the OPENSSL_cleanup
+ is registered when libcrypto is unloaded.
+
+ * Added X509_STORE_get1_objects to avoid issues with the existing
+ X509_STORE_get0_objects API in multi-threaded applications.
+
+This release incorporates the following potentially significant or incompatible
+changes:
+
+ * Applied AES-GCM unroll8 optimisation to Microsoft Azure Cobalt 100
+
+ * Optimized AES-CTR for ARM Neoverse V1 and V2
+
+ * Enable AES and SHA3 optimisations on Applie Silicon M3-based MacOS systems
+ similar to M1/M2.
+
+ * Various optimizations for cryptographic routines using RISC-V vector crypto
+ extensions
+
+ * Added assembly implementation for md5 on loongarch64
+
+ * Accept longer context for TLS 1.2 exporters
+
+ * The activate and soft_load configuration settings for providers in
+ openssl.cnf have been updated to require a value of [1|yes|true|on]
+ (in lower or UPPER case) to enable the setting. Conversely a value
+ of [0|no|false|off] will disable the setting.
+
+ * In `openssl speed`, changed the default hash function used with `hmac` from
+ `md5` to `sha256`.
+
+ * The `-verify` option to the `openssl crl` and `openssl req` will make the
+ program exit with 1 on failure.
+
+ * The d2i_ASN1_GENERALIZEDTIME(), d2i_ASN1_UTCTIME(), ASN1_TIME_check(), and
+ related functions have been augmented to check for a minimum length of
+ the input string, in accordance with ITU-T X.690 section 11.7 and 11.8.
+
+ * OPENSSL_sk_push() and sk_<TYPE>_push() functions now return 0 instead of -1
+ if called with a NULL stack argument.
+
+ * New limit on HTTP response headers is introduced to HTTP client. The
+ default limit is set to 256 header lines.
+
+This release incorporates the following bug fixes and mitigations:
+
+ * The BIO_get_new_index() function can only be called 127 times before it
+ reaches its upper bound of BIO_TYPE_MASK and will now return -1 once its
+ exhausted.
+
+A more detailed list of changes in this release can be found in the
+[CHANGES.md] file.
+
+Users interested in using the new QUIC functionality are encouraged to read the
+[README file for QUIC][README-QUIC.md], which provides links to relevant
+documentation and example code.
+
+As always, bug reports and issues relating to OpenSSL can be [filed on our issue
+tracker][issue tracker].
