+            in the process of generating certificates.
+          - Fixed a variety of memory corruption issues in BIO chains coming
+            from poor old and new API: BIO_push(), BIO_pop(), BIO_set_next().

+            Poly1305 is not currently supported via this interface.
+
+3.6.1 - Stable release
+

+          - Clean up and clarify BN_kronecker().
+          - Simplify ASN1_INTEGER_cmp()

+          - ASN1_AFLG_BROKEN was removed.
+          - Error check tls_session_secret_cb() like OpenSSL.
+          - Added ASN1_INTEGER_{get,set}_{u,}int64()

+            supported by the specified protocol.
+          - Use TLS_client_method() instead of TLSv1_client_method() in
+            the openssl(1) ciphers command.

+          - Avoid use of uninitialized in BN_mod_exp_recp().
+          - Fix X509_get_extension_flags() by ensuring that EXFLAG_INVALID is
+            set on X509_get_purpose() failure.

+          - Do not return X509_V_ERR_UNSPECIFIED from X509_check_ca().
+            No return value of X509_check_ca() indicates failure. Application
+            code should therefore issue a checked call to X509_check_purpose()
+            before calling X509_check_ca().
+          - Rewrite and fix X509v3_asid_subset() to avoid segfaults on some
+            valid input.
+          - Call the ASN1_OP_D2I_PRE callback after ASN1_item_ex_new().
+          - Fix d2i_ASN1_OBJECT to advance the *der_in pointer correctly.
+          - Avoid use of uninitialized in ASN1_STRING_to_UTF8().
+          - Do not pass uninitialized pointer to ASN1_STRING_to_UTF8().
+          - Do not refuse valid IPv6 addresses in nc(1)'s HTTP CONNECT proxy.
+          - Do not reject primes in trial divisions.
+          - Error out on negative shifts in BN_{r,l}shift() instead of
+            accessing arrays out of bounds.
+          - Fix URI name constraints, allow for URI's with no host part.
+          - Fix the legacy verifier callback behaviour for untrusted certs.
+          - Correct serfver-side handling of TLSv1.3 key updates.
+          - Plug leak in PKCS12_setup_mac().
+          - Plug leak in X509V3_add1_i2d().
+          - Only print X.509 versions we know about.
+          - Avoid signed integer overflow due to unary negation
+          - Initialize readbytes in BIO_gets().
+          - Plug memory leak in CMS_add_simple_smimecap().
+          - Plug memory leak in X509_REQ_print_ex().
+          - Check HMAC() return value to avoid a later use of uninitialized.
+          - Avoid potential NULL dereference in ssl_set_pkey().
+          - Check return values in ssl_print_tmp_key().
+          - Switch loop bounds from size_t to int in check_hosts().
+          - Avoid division by zero if no connection was made in s_time.c.
+          - Check sk_SSL_CIPHER_push() return value
+          - Avoid out-of-bounds read in ssl_cipher_process_rulestr().
+          - Use LONG_MAX as the limit for ciphers with long based APIs.
+        * New features
+          - EVP API for HKDF ported from OpenSSL and subsequently cleaned up.
+          - The security level API (SSL_{,CTX}_{get,set}_security_level()) is
+            now available. Callbacks and ex_data are not supported. Sane
+            software will not be using this.
+          - Experimental support for the BoringSSL QUIC API.
+          - Add initial support for TS ESSCertIDv2 verification.
+          - LibreSSL now uses the Baillie-PSW primality test instead of
+            Miller-Rabin .
+
+3.5.3 - Reliability fix
+
+        * Fix d2i_ASN1_OBJECT(). A confusion of two CBS resulted in advancing
+          the passed *der_in pointer incorrectly. Thanks to Aram Sargsyan for
+          reporting the issue and testing the fix.
+
 3.5.2 - Stable release
 
         * Bug fixes
