104+ * Compatibility changes
105+ - The ASN.1 time parser has been refactored and rewritten using CBS.
106+ It has been made stricter in that it now enforces the rules from
107+ RFC 5280.
108+ - ASN1_AFLG_BROKEN was removed.
109+ - Error check tls_session_secret_cb() like OpenSSL.
110+ - Added ASN1_INTEGER_{get,set}_{u,}int64()
111+ - Move leaf certificate checks to the last thing after chain
112+ validation.
113+ - Added -s option to openssl(1) ciphers that only shows the ciphers
114+ supported by the specified protocol.
115+ - Use TLS_client_method() instead of TLSv1_client_method() in
116+ the openssl(1) ciphers command.
117+ - Validate the protocols in SSL{_CTX,}_set_alpn_protos().
118+ - Made TS and PKCS12 opaque.
119+ - Per RFC 7292, safeContentsBag is a SEQUENCE OF, not a SET OF.
120+ - Align PKCS12_key_gen_uni() with OpenSSL
121+ - Various PKCS12 and TS accessors were added. In particular, the
122+ TS_RESP_CTX_set_time_cb() function was added back.
123+ - Allow a NULL header in PEM_write{,_bio}()
124+ - Allow empty attribute sets in CSRs.
125+ - Adjust signatures of BIO_ctrl functions.
126+ - Provide additional defines for EVP AEAD.
127+ - Provide OPENSSL_cleanup().
128+ - Make BIO_info_cb() identical to bio_info_cb().
129+ * Bug fixes
130+ - Avoid use of uninitialized in BN_mod_exp_recp().
131+ - Fix X509_get_extension_flags() by ensuring that EXFLAG_INVALID is
132+ set on X509_get_purpose() failure.
133+ - Fix HMAC() with NULL key.
134+ - Add ERR_load_{COMP,CT,KDF}_strings() to ERR_load_crypto_strings().
135+ - Avoid strict aliasing violations in BN_nist_mod_*().
136+ - Do not return X509_V_ERR_UNSPECIFIED from X509_check_ca().
137+ No return value of X509_check_ca() indicates failure. Application
138+ code should therefore issue a checked call to X509_check_purpose()
139+ before calling X509_check_ca().
140+ - Rewrite and fix X509v3_asid_subset() to avoid segfaults on some
141+ valid input.
142+ - Call the ASN1_OP_D2I_PRE callback after ASN1_item_ex_new().
143+ - Fix d2i_ASN1_OBJECT to advance the *der_in pointer correctly.
144+ - Avoid use of uninitialized in ASN1_STRING_to_UTF8().
145+ - Do not pass uninitialized pointer to ASN1_STRING_to_UTF8().
146+ - Do not refuse valid IPv6 addresses in nc(1)'s HTTP CONNECT proxy.
147+ - Do not reject primes in trial divisions.
148+ - Error out on negative shifts in BN_{r,l}shift() instead of
149+ accessing arrays out of bounds.
150+ - Fix URI name constraints, allow for URI's with no host part.
151+ - Fix the legacy verifier callback behaviour for untrusted certs.
152+ - Correct serfver-side handling of TLSv1.3 key updates.
153+ - Plug leak in PKCS12_setup_mac().
154+ - Plug leak in X509V3_add1_i2d().
155+ - Only print X.509 versions we know about.
156+ - Avoid signed integer overflow due to unary negation
157+ - Initialize readbytes in BIO_gets().
158+ - Plug memory leak in CMS_add_simple_smimecap().
159+ - Plug memory leak in X509_REQ_print_ex().
160+ - Check HMAC() return value to avoid a later use of uninitialized.
161+ - Avoid potential NULL dereference in ssl_set_pkey().
162+ - Check return values in ssl_print_tmp_key().
163+ - Switch loop bounds from size_t to int in check_hosts().
164+ - Avoid division by zero if no connection was made in s_time.c.
165+ - Check sk_SSL_CIPHER_push() return value
166+ - Avoid out-of-bounds read in ssl_cipher_process_rulestr().
167+ - Use LONG_MAX as the limit for ciphers with long based APIs.
168+ * New features
169+ - EVP API for HKDF ported from OpenSSL and subsequently cleaned up.
170+ - The security level API (SSL_{,CTX}_{get,set}_security_level()) is
171+ now available. Callbacks and ex_data are not supported. Sane
172+ software will not be using this.
173+ - Experimental support for the BoringSSL QUIC API.
174+ - Add initial support for TS ESSCertIDv2 verification.
175+ - LibreSSL now uses the Baillie-PSW primality test instead of
176+ Miller-Rabin .
