MySQL Connector/Python Release Notes
Added DNS SRV support.
To automatically resolve any SRV record available in a target
DNS server or service discovery endpoint, use the
mysqlx+srv scheme+extension in a X DevAPI
connection string, or mysqlx+srv for the
classic protocol, or by enabling the dns-srv=True (or
dns_srv=True) connection option when using keyword arguments or
dictionaries.
(WL #13372)
Added two new connection options that evaluate during the TLS
handshake to restrict the negotiated TLS protocols and ciphers;
along with those configured on the server that can further
restrict the final choices. The new options are
tls-versions to define the allowed TLS protocol
versions, and tls-ciphersuites for the allowed
cipher suites. These definitions are comma-separated, and
accepted by the getSession() and
getClient() methods.
tls-versions: accepts one or more of the
following: TLSv1, TLSv1.1, TLSv1.2, and TLSv1.3. Other values
generate an error. Example usage:
mysqlx://myserver/db?tls-versions=[TLSv1.2,TLSv1.3]
tls-ciphersuites: accepts IANA cipher suite
names, as listed on IANA's
TLS
Cipher Suites page. Unsupported or unknown values are
ignored. Example usage:
mysqlx://myserver/db?tls-ciphersuites=[TLS_DHE_PSK_WITH_AES_128_GCM_SHA256,
TLS_CHACHA20_POLY1305_SHA256]
(WL #12738)
The internal X Protocol namespace changed from xplugin to mysqlx. MySQL Server removed xplugin namespace support in v8.0.19; for Connector/Python this means:
With Connector/Python v8.0.19 and higher, some X DevAPI Protocol operations do not function with MySQL Server 8.0.18 and lower, operations such as Schema.create_collection(), Schema.get_collections(), Schema.get_tables(), and Collection.create_index().
Connector/Python 8.0.19 can connect to MySQL Server 8.0.18 and lower, as both the 'xplugin' (with deprecation warnings) and 'mysqlx' namespaces can be used.

Fixed the reserved SSL authentication filed; it changed from 23 to 22. Thanks to Qianqian Bu for the patch. (Bug #30270760, Bug #96770)
References: This issue is a regression of: Bug #29855733.
Fixed LOAD DATA INFILE LOCAL handling; the file handle was not closed. Thanks to Micah Gale for the patch. (Bug #29417117, Bug #94496)
