CHANGELOG.md

Changelog

0.20a1

• Improvements

  • Add Knox cookies in default cookies list (#525)
  • Support CHAR type in SQLAlchemy (#516)
  • Support Cursor.rowcount and close finished queries (#528) Note that this is a potentially breaking change. See the PR for details about the side-effects. The old behavior can be restored by setting close_finished_queries=False when creating a Cursor. Also note that Cursor.rowcount only works with Impala server - with Hive it will always return -1.

• Bug Fixes

  • Fix https connection with Python 3.12 (#531) Note that Python 3.12 support is not complete yet. A known issue is that installing with setuptools fails with Python 3.12.

0.18.0

• Improvements

  • Add support for retaining cookies among http requests for LDAP and GSSAPI/PLAIN SASL (#465) Notes: Authentication cookie is enabled by default.
