I'm happy to announce the release of Psycopg 2.4.6: a huge thank you to the many contributors.

This is a bugfix release, introducing no new feature. There are several small corrections in different areas (copy, adaptation, use of extra cursors, stability). The biggest improvements are with the Zope adapter: Zope users using previous 2.4.x versions are encouraged to update to version 2.4.6 soon.

What's new in psycopg 2.4.6

  • Fixed 'cursor()' arguments propagation in connection subclasses and overriding of the 'cursor_factory' argument. Thanks to Corry Haines for the report and the initial patch (ticket #105).
  • Dropped GIL release during string adaptation around a function call invoking a Python API function, which could cause interpreter crash. Thanks to Manu Cupcic for the report (ticket #110).
  • Close a green connection if there is an error in the callback. Maybe a harsh solution but it leaves the program responsive (ticket #113).
  • 'register_hstore()', 'register_composite()', 'tpc_recover()' work with RealDictConnection and Cursor (ticket #114).
  • Fixed broken pool for Zope and connections re-init across ZSQL methods in the same request (tickets #123, #125, #142).
  • connect() raises an exception instead of swallowing keyword arguments when a connection string is specified as well (ticket #131).
  • Discard any result produced by 'executemany()' (ticket #133).
  • Fixed pickling of FixedOffsetTimezone objects (ticket #135).
  • Release the GIL around PQgetResult calls after COPY (ticket #140).
  • Fixed empty strings handling in composite caster (ticket #141).
  • Fixed pickling of DictRow and RealDictRow objects.
