The extra option name for wheel package installation of

(Bug #37806057)
The pure-Python implementation of Connector/Python now supports
Django enum
objects and
ChoiceField
when executing queries using
Django ORM.
(Bug #116056, Bug #37047789)
Connection pooling support for AsyncIO connections is now available.
Thanks to Sean Stewart for contributing this patch. (Bug #114926, Bug #36733242)
The version of Protobuf required by and installed with the X DevAPI has been updated to 5.29.4. (WL #16962)
The LZ4 package, which is shipped with Connector/Python and
installed with the X DevAPI by the
compression
installation option, has now been
upgraded to version 4.4.4.
(WL #16966)
The version of OpenTelemetry required by and installed with the
classic API by the telemetry
installation
option has been updated to 1.33.1.
(WL #16963)
When making asynchronous connections to the server using
Connector/Python, OCI plugin options like
oci_config_file
and
oci_config_profile
were not recognized and
caused connections to fail.
(Bug #38072835)
Queries on text-type fields like Charfield and TextField failed
when Django ORM filters (for example,
startswith
, endswith
,
contains
, and regex
) were
used. It was because Connector/Python was using some deprecated
MySQL commands behind the scene, and they have now been updated.
(Bug #37820231)
Binary data containing double percent signs (%%) was not correctly persisted in BLOB columns, but had the first percentage sign stripped. (Bug #118025, Bug #37859771)
References: This issue is a regression of: Bug #37447394.
Unlike when using the C extension, the pure-Python implementation could not convert NumPy float62 values into a MySQL type during a query. With this fix, conversion works, so that the C Extension and pure-Python implementations are now consistent in this respect. (Bug #117827, Bug #37774513)
When using the Connector/Python C Extension with an unbuffered
server-side cursor, fetchmany(1)
failed to
fetch more results after reading the second row in the result
set.
(Bug #117548, Bug #37627508)
When using the Connector/Python C Extension, connections to a
server using sshtunnel
failed, with the connection hanging, or a
segmentation fault.
(Bug #108761, Bug #34844347, Bug #34950958)
Installation of Connector/Python using the source distribution
failed. With release 9.4.0, Connector/Python is now installable from

. See

details.
