psycopg2/NEWS

What's new in psycopg 1.99.11
-----------------------------

* 'cursor' argument in .cursor() connection method renamed to 
  'cursor_factory'.

* changed 'tuple_factory' cursor attribute name to 'row_factory'.

* the .cursor attribute is gone and connections and cursors are propely
  gc-managed.

What's new in psycopg 1.99.10
-----------------------------

* The adapt() function now fully supports the adaptation protocol
  described in PEP 246. Note that the adapters registry now is indexed
  by (type, protocol) and not by type alone. Change your adapters
  accordingly.

* More configuration options moved from setup.py to setup.cfg.

* Fixed two memory leaks: one in cursor deallocation and one in row
  fetching (.fetchXXX() methods.)

What's new in psycopg 1.99.9
----------------------------

* Added simple pooling code (psycopg.pool module); see the reworked
  examples/threads.py for example code.

* Added DECIMAL typecaster to convert postgresql DECIMAL and NUMERIC
  types (i.e, all types with an OID of NUMERICOID.) Note that the
  DECIMAL typecaster does not set scale and precision on the created
  objects but uses Python defaults.

* ZPsycopgDA back in and working using the new pooling code.

* Isn't that enough? :)

What's new in psycopg 1.99.8
----------------------------

* added support for UNICODE queries.

* added UNICODE typecaster; to activate it just do:
    
    psycopg.extensions.register_type(psycopg.extensions.UNICODE)
  
  Note that the UNICODE typecaster override the STRING one, so it is
  not activated by default.

* cursors now really support the iterator protocol.

* solved the rounding errors in time conversions.

* now cursors support .fileno() and .isready() methods, to be used in
  select() calls.

* .copy_from() and .copy_in() methods are back in (still using the old
  protocol, will be updated to use new one in next releasae.)

* fixed memory corruption bug reported on win32 platform.

What's new in psycopg 1.99.7
----------------------------

* added support for tuple factories in cursor objects (removed factory
  argument in favor of a .tuple_factory attribute on the cursor object);
  see the new module psycopg.extras for a cursor (DictCursor) that
  return rows as objects that support indexing both by position and
  column name.

* added support for tzinfo objects in datetime.timestamp objects: the
  PostgreSQL type "timestamp with time zone" is converted to 
  datetime.timestamp with a FixedOffsetTimezone initialized as necessary.

What's new in psycopg 1.99.6
----------------------------

* sslmode parameter from 1.1.x

* various datetime conversion improvements.

* now psycopg should compile without mx or without native datetime
  (not both, obviously.)

* included various win32/MSVC fixes (pthread.h changes, winsock2
  library, include path in setup.py, etc.)

* ported interval fixes from 1.1.14/1.1.15.

* the last query executed by a cursor is now available in the
  .query attribute.

* conversion of unicode strings to backend encoding now uses a table
  (that still need to be filled.)

* cursors now have a .mogrify() method that return the query string
  instead of executing it.

* connection objects now have a .dsn read-only attribute that holds the
  connection string.

* moved psycopg C module to _psycopg and made psycopg a python module:
  this allows for a neat separation of DBAPI-2.0 functionality and psycopg
  extensions; the psycopg namespace will be also used to provide
  python-only extensions (like the pooling code, some ZPsycopgDA support
  functions and the like.)

What's new in psycopg 1.99.3
----------------------------

* added support for python 2.3 datetime types (both ways) and made datetime
  the default set of typecasters when available.

* added example: dt.py.

What's new in psycopg 1.99.3
----------------------------

* initial working support for unicode bound variables: UTF-8 and latin-1
  backend encodings are natively supported (and the encoding.py example even
  works!)

* added .set_client_encoding() method on the connection object.

* added examples: encoding.py, binary.py, lastrowid.py.

What's new in psycopg 1.99.2
----------------------------

* better typecasting:
  - DateTimeDelta used for postgresql TIME (merge from 1.1)
  - BYTEA now is converted to a real buffer object, not to a string

* buffer objects are now adapted into Binary objects automatically.

* ported scroll method from 1.1 (DBAPI-2.0 extension for cursors)

* initial support for some DBAPI-2.0 extensions:
  - .rownumber attribute for cursors
  - .connection attribute for cursors
  - .next() and .__iter__() methods to have cursors support the iterator
    protocol
  - all exception objects are exported to the connection object

What's new in psycopg 1.99.1
----------------------------

* implemented microprotocols to adapt arbitrary types to the interface used by
  psycopg to bind variables in execute;

* moved qstring, pboolean and mxdatetime to the new adapter layout (binary is
  still missing; python 2.3 datetime needs to be written).


What's new in psycopg 1.99.0
----------------------------

* reorganized the whole source tree;

* async core is in place;

* splitted QuotedString objects from mx stuff;

* dropped autotools and moved to pythonic setup.py (needs work.)
