Psycopg 2.6 is now

New features:

  and the MAAS Team for the feature development.
- Python `time` objects with a tzinfo specified and PostgreSQL :sql:`timetz`
  data are converted into each other (🎫`psycopg#272`).

Bug fixes:

- Json apapter's `!str()` returns the adapted content instead of the `!repr()`
  (:ticket:`psycopg#191`).

Psycopg 2.5.5 released

- Named cursors used as context manager don't swallow the exception on exit
  (:ticket:`psycopg#262`).
- `cursor.description` can be pickled (:ticket:`psycopg#265`).

Psycopg 2.5.4 released

- Added :sql:`jsonb` support for PostgreSQL 9.4 (🎫`psycopg#226`).

  of using the proper methods (:ticket:`psycopg#219`).

  pools (:ticket:`psycopg#220`).

  (🎫`psycopg#228`).
- Cursors :sql:`WITH HOLD` can be used in autocommit (🎫`psycopg#229`).
- `~cursor.callproc()` doesn't silently ignore an argument without a length.
- Fixed memory leak with large objects (:ticket:`psycopg#256`).
- Make sure the internal ``_psycopg.so`` module can be imported stand-alone (to
  allow modules juggling such as the one described in 🎫`psycopg#201`).

Psycopg 2.5.3 released

- Work around `pip issue psycopg#1630 <https://github.com/pypa/pip/issues/1630>`__
  making installation via ``pip -e git+url`` impossible (:ticket:`#18`).
- Copy operations correctly set the `cursor.rowcount` attribute
  (:ticket:`psycopg#180`).
- It is now possible to call `get_transaction_status()` on closed connections.
- Fixed unsafe access to object names causing assertion failures in
  Python 3 debug builds (:ticket:`psycopg#188`).
- Mark the connection closed if found broken on `poll()` (from 🎫`psycopg#192`
  discussion)
- Fixed handling of dsn and closed attributes in connection subclasses
  failing to connect (from 🎫`psycopg#192` discussion).
- Added arbitrary but stable order to `Range` objects, thanks to
  Chris Withers (:ticket:`psycopg#193`).
- Avoid blocking async connections on connect (:ticket:`psycopg#194`). Thanks to
  Adam Petrovich for the bug report and diagnosis.
- Don't segfault using poorly defined cursor subclasses which forgot to call
  the superclass init (:ticket:`psycopg#195`).

  happens for TCP connections instead (:ticket:`psycopg#196`).
- Fixed overflow opening a lobject with an oid not fitting in a signed int
  (:ticket:`psycopg#203`).

  `connection.cursor()` (:ticket:`psycopg#210`).
- Fixed possible segfault in named cursors creation.
- Fixed debug build on Windows, thanks to James Emerton.

Psycopg 2.5.2 released

  ticket psycopg#170.
- Meaningful connection errors report a meaningful message, thanks to
  Alexey Borzenkov (ticket psycopg#173).
- Manually creating 'lobject' with the wrong parameter doesn't segfault
  (ticket psycopg#187).

Psycopg 2.5.1 released

- Fixed build on Solaris 10 and 11 where the round() function is already
  declared (ticket psycopg#146).
- Fixed comparison of 'Range' with non-range objects (ticket psycopg#164).

Psycopg 2.5 released

New features:

- Added JSON adaptation.
- Added support for PostgreSQL 9.2 range types .
- 'connection' and 'cursor' objects can be used in "with" statements
  as context managers as specified by a recent DBAPI  extension.
- Added 'Diagnostics' object to get extended info from a database error.
  Many thanks to Matthew Woodcraft for the implementation (ticket psycopg#149).
- Added 'connection.cursor_factory' attribute to customize the default
  object returned by 'cursor()'.
- Added support for backward scrollable cursors. Thanks to Jon Nelson
  for the initial patch (ticket psycopg#108).
- Added a simple way to customize casting of composite types into
  Python objects other than namedtuples.  Many thanks to Ronan Dunklau
  and Tobias Oberstein for the feature development.
- 'connection.reset()' implemented using 'DISCARD ALL' on server
  versions supporting it.

Bug fixes:

- Properly cleanup memory of broken connections (ticket psycopg#148).
- Fixed bad interaction of 'setup.py' with other dependencies in
  Distribute projects on Python 3 (ticket psycopg#153).

Other changes:

- Added support for Python 3.3.
- Dropped support for Python 2.4. Please use Psycopg 2.4.x if you
  need it.
- 'errorcodes' map updated to PostgreSQL 9.2.
- Dropped Zope adapter from source repository. ZPsycopgDA now has its
  own project at <http://github.com/psycopg/ZPsycopgDA>.

Release 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 psycopg#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 psycopg#110).
- Close a green connection if there is an error in the callback.
  Maybe a harsh solution but it leaves the program responsive
  (ticket psycopg#113).
- 'register_hstore()', 'register_composite()', 'tpc_recover()' work with
  RealDictConnection and Cursor (ticket psycopg#114).
- Fixed broken pool for Zope and connections re-init across ZSQL methods
  in the same request (tickets psycopg#123, psycopg#125, psycopg#142).
- connect() raises an exception instead of swallowing keyword arguments
  when a connection string is specified as well (ticket psycopg#131).
- Discard any result produced by 'executemany()' (ticket psycopg#133).
- Fixed pickling of FixedOffsetTimezone objects (ticket psycopg#135).
- Release the GIL around PQgetResult calls after COPY (ticket psycopg#140).
- Fixed empty strings handling in composite caster (ticket psycopg#141).
- Fixed pickling of DictRow and RealDictRow objects.
