eb33768e
TM		 36OpenSSL 3.3.0 is a feature release adding significant new functionality to
37OpenSSL.
38
39This release adds the following new features:
40
41 * Support for qlog for tracing QUIC connections has been added
42
43 * Added APIs to allow configuring the negotiated idle timeout for QUIC
44 connections, and to allow determining the number of additional streams
45 that can currently be created for a QUIC connection.
46
47 * Added APIs to allow disabling implicit QUIC event processing for QUIC SSL
48 objects
49
50 * Added APIs to allow querying the size and utilisation of a QUIC stream's
51 write buffer
52
53 * New API `SSL_write_ex2`, which can be used to send an end-of-stream (FIN)
54 condition in an optimised way when using QUIC.
55
56 * Limited support for polling of QUIC connection and stream objects in a
57 non-blocking manner.
58
59 * Added a new EVP_DigestSqueeze() API. This allows SHAKE to squeeze multiple
60 times with different output sizes.
61
10264b53
RL		 62 * Added exporter for CMake on Unix and Windows, alongside the pkg-config
63 exporter.
186b3f6a 64
eb33768e
TM		 65 * The BLAKE2s hash algorithm matches BLAKE2b's support for configurable
66 output length.
67
68 * The EVP_PKEY_fromdata function has been augmented to allow for the
69 derivation of CRT (Chinese Remainder Theorem) parameters when requested
70
71 * Added API functions SSL_SESSION_get_time_ex(), SSL_SESSION_set_time_ex()
72 using time_t which is Y2038 safe on 32 bit systems when 64 bit time
73 is enabled
74
75 * Unknown entries in TLS SignatureAlgorithms, ClientSignatureAlgorithms
76 config options and the respective calls to SSL[_CTX]_set1_sigalgs() and
77 SSL[_CTX]_set1_client_sigalgs() that start with `?` character are
78 ignored and the configuration will still be used.
79
80 * Added `-set_issuer` and `-set_subject` options to `openssl x509` to
81 override the Issuer and Subject when creating a certificate. The `-subj`
82 option now is an alias for `-set_subject`.
83
84 * Added several new features of CMPv3 defined in RFC 9480 and RFC 9483
85
86 * New option `SSL_OP_PREFER_NO_DHE_KEX`, which allows configuring a TLS1.3
87 server to prefer session resumption using PSK-only key exchange over PSK
88 with DHE, if both are available.
89
90 * New atexit configuration switch, which controls whether the OPENSSL_cleanup
91 is registered when libcrypto is unloaded.
92
93 * Added X509_STORE_get1_objects to avoid issues with the existing
94 X509_STORE_get0_objects API in multi-threaded applications.
95
96This release incorporates the following potentially significant or incompatible
97changes:
98
99 * Applied AES-GCM unroll8 optimisation to Microsoft Azure Cobalt 100
100
101 * Optimized AES-CTR for ARM Neoverse V1 and V2
102
103 * Enable AES and SHA3 optimisations on Applie Silicon M3-based MacOS systems
104 similar to M1/M2.
105
106 * Various optimizations for cryptographic routines using RISC-V vector crypto
107 extensions
108
109 * Added assembly implementation for md5 on loongarch64
110
111 * Accept longer context for TLS 1.2 exporters
112
113 * The activate and soft_load configuration settings for providers in
114 openssl.cnf have been updated to require a value of [1|yes|true|on]
115 (in lower or UPPER case) to enable the setting. Conversely a value
116 of [0|no|false|off] will disable the setting.
117
118 * In `openssl speed`, changed the default hash function used with `hmac` from
119 `md5` to `sha256`.
120
121 * The `-verify` option to the `openssl crl` and `openssl req` will make the
122 program exit with 1 on failure.
123
124 * The d2i_ASN1_GENERALIZEDTIME(), d2i_ASN1_UTCTIME(), ASN1_TIME_check(), and
125 related functions have been augmented to check for a minimum length of
126 the input string, in accordance with ITU-T X.690 section 11.7 and 11.8.
127
128 * OPENSSL_sk_push() and sk_<TYPE>_push() functions now return 0 instead of -1
129 if called with a NULL stack argument.
130
131 * New limit on HTTP response headers is introduced to HTTP client. The
132 default limit is set to 256 header lines.
133
134This release incorporates the following bug fixes and mitigations:
135
136 * The BIO_get_new_index() function can only be called 127 times before it
137 reaches its upper bound of BIO_TYPE_MASK and will now return -1 once its
138 exhausted.
139
140A more detailed list of changes in this release can be found in the
141[CHANGES.md] file.
142
143Users interested in using the new QUIC functionality are encouraged to read the
144[README file for QUIC][README-QUIC.md], which provides links to relevant
145documentation and example code.
146
147As always, bug reports and issues relating to OpenSSL can be [filed on our issue
148tracker][issue tracker].
