For more details please read the CHANGES file. 6 7OpenSSL Releases 8---------------- 9 10 - [OpenSSL 3.5](#openssl-35) 11 - [OpenSSL 3.4](#openssl-34) 12 - [OpenSSL 3.3](#openssl-33) 13 - [OpenSSL 3.2](#openssl-32) 14 - [OpenSSL 3.1](#openssl-31) 15 - [OpenSSL 3.0](#openssl-30) 16 - [OpenSSL 1.1.1](#openssl-111) 17 - [OpenSSL 1.1.0](#openssl-110) 18 - [OpenSSL 1.0.2](#openssl-102) 19 - [OpenSSL 1.0.1](#openssl-101) 20 - [OpenSSL 1.0.0](#openssl-100) 21 - [OpenSSL 0.9.x](#openssl-09x) 22 23OpenSSL 3.5 24----------- 25 26### Major changes between OpenSSL 3.4 and OpenSSL 3.5 [under development] 27 28OpenSSL 3.5.0 is a feature release adding significant new functionality to 29OpenSSL. 30 31This release is in development. 32 33This release incorporates the following potentially significant or incompatible 34changes: 35 36 * Default encryption cipher for the `req`, `cms`, and `smime` applications 37 changed from `des-ede3-cbc` to `aes-256-cbc`. 38 39This release adds the following new features: 40 41 * Allow the FIPS provider to optionally use the `JITTER` seed source. 42 Because this seed source is not part of the OpenSSL FIPS validations, 43 it should only be enabled after the [jitterentropy-library] has been 44 assessed for entropy quality. Moreover, the FIPS provider including 45 this entropy source will need to obtain an [ESV] from the [CMVP] before 46 FIPS compliance can be claimed. Enable this using the configuration 47 option `enable-fips-jitter`. 48 49OpenSSL 3.4 50----------- 51 52### Major changes between OpenSSL 3.3 and OpenSSL 3.4 [under development] 53 54OpenSSL 3.4.0 is a feature release adding significant new functionality to 55OpenSSL. 56 57This release is in development. 58 59This release incorporates the following potentially significant or incompatible 60changes: 61 62 * Deprecation of TS_VERIFY_CTX_set_* functions and addition of replacement 63 TS_VERIFY_CTX_set0_* functions with improved semantics 64 65 * Redesigned use of OPENSSLDIR/ENGINESDIR/MODULESDIR on Windows such that 66 what were formerly build time locations can now be defined at run time 67 with registry keys 68 69 * The X25519 and X448 key exchange implementation in the FIPS provider 70 is unapproved and has `fips=no` property. 71 72 * SHAKE-128 and SHAKE-256 implementations have no default digest length 73 anymore. That means these algorithms cannot be used with 74 EVP_DigestFinal/_ex() unless the `xoflen` param is set before. 75 76 * Setting `config_diagnostics=1` in the config file will cause errors to 77 be returned from SSL_CTX_new() and SSL_CTX_new_ex() if there is an error 78 in the ssl module configuration. 79 80 * An empty renegotiate extension will be used in TLS client hellos instead 81 of the empty renegotiation SCSV, for all connections with a minimum TLS 82 version > 1.0. 83 84 * Deprecation of SSL_SESSION_get_time(), SSL_SESSION_set_time() and 85 SSL_CTX_flush_sessions() functions in favor of their respective `_ex` 86 functions which are Y2038-safe on platforms with Y2038-safe `time_t` 87 88This release adds the following new features: 89 90 * Support for directly fetched composite signature algorithms such as 91 RSA-SHA2-256 including new API functions 92 93 * FIPS indicators support in the FIPS provider and various updates of the FIPS 94 provider required for future FIPS 140-3 validations 95 96 * Implementation of RFC 9579 (PBMAC1) in PKCS#12 97 98 * An optional additional random seed source RNG `JITTER` using a statically 99 linked jitterentropy library 100 101 * New options `-not_before` and `-not_after` for explicit setting start and 102 end dates of certificates created with the `req` and `x509` apps 103 104 * Support for integrity-only cipher suites TLS_SHA256_SHA256 and 105 TLS_SHA384_SHA384 in TLS 1.3, as defined in RFC 9150 106 107 * Support for requesting CRL in CMP 108 109 * Support for additional X.509v3 extensions related to Attribute Certificates 110 111 * Initial Attribute Certificate (RFC 5755) support 112 113 * Possibility to customize ECC groups initialization to use precomputed values 114 to save CPU time and use of this feature by the P-256 implementation 115 116OpenSSL 3.3 117----------- 118 119### Major changes between OpenSSL 3.3.2 and OpenSSL 3.3.3 [under development] 120 121OpenSSL 3.3.3 is a security patch release.
