RELEASE: 2.4 beta 1

Hi *,

me and Daniele, we just went through his series of patches (a loooot of
patches) and we're ready to release a beta version of the new psycopg.
Apart the usual changes and enhancements (detailed below) this is the
first version that supports Python 3 (thanks to, guess who? :)

Here are the download links:

And the NEWS excerpt:

What's new in psycopg 2.4
-------------------------

* New features and changes:

  - Added `register_composite()` function to cast PostgreSQL composite
    types into Python tuples/namedtuples.
  - More efficient iteration on named cursors.
  - The build script refuses to guess values if pg_config is not found.
  - Connections and cursors are weakly referenceable.
  - Added 'b' and 't' mode to large objects: write can deal with both
    bytes strings and unicode; read can return either bytes strings or
    decoded unicode.
  - COPY sends Unicode data to files implementing io.TextIOBase.
  - The build script refuses to guess values if pg_config is not found.
  - Improved PostgreSQL-Python encodings mapping. Added a few
    missing encodings: EUC_CN, EUC_JIS_2004, ISO885910, ISO885916,
    LATIN10, SHIFT_JIS_2004.
  - Dropped repeated dictionary lookups with unicode query/parameters.
  - Empty lists correctly roundtrip Python -> PostgreSQL -> Python.

* Bug fixes:

  - Fixed adaptation of None in composite types (ticket #26). Bug
    report by Karsten Hilbert.
  - Fixed several reference leaks in less common code paths.
  - Fixed segfault when a large object is closed and its connection no
    more available.
  - Added missing icon to ZPsycopgDA package, not available in Zope
    2.12.9 (ticket #30). Bug report and patch by Pumukel.


Have fun,
federico
