We have just released two Psycopg versions: 2.5.5 containing a few bug
fixes and 2.6 introducing some new features.
The main new feature in Psycopg 2.6 is the support for the large
objects 64 bits API, allowing access to large objects of more than 2GB
size. Note that the feature is only supported on 64 bits clients and
with at least PostgreSQL 9.3 server and client library.
I wish to thank all the people who have contributed to these releases,
and especially Blake Rouse and the MAAS Team for the development of
the large objects 64 bits API support.

This is the full list of changes for the new versions:

- Python time objects with a tzinfo specified and PostgreSQL timetz data are
converted into each other (ticket #272).
- Psycopg 2.6 bug fixes
- Json adapter's str() returns the adapted content instead of the repr()
(ticket #191).
- Psycopg 2.5.5 bug fixes
- Named cursors used as context manager don't swallow the exception on exit
(ticket #262).
- cursor.description can be pickled (ticket #265).
- Propagate read error messages in COPY FROM (ticket #270).
- PostgreSQL time 24:00 is converted to Python 00:00 (ticket #278).
A further note for the packagers: the Psycopg 2.6 source tarball
doesn't contain the HTML rendered documentation anymore: you will find
Makefile targets to easily build it.

programming language. At its core it fully implements the Python DB
API 2.0 specifications. Several extensions allow access to many of the
features offered by PostgreSQL.
