| 2 | +Announce: Release of PyGreSQL version 2.3 |
| 3 | +=============================================== |
| 4 | + |
| 5 | +PyGreSQL v2.3 has been released. |
| 6 | +It is available at: ftp://ftp.druid.net/pub/distrib/PyGreSQL.tgz. If |
| 7 | +you are on NetBSD, look in the packages directory under databases. If |
| 8 | +it isn't there yet, it should be there shortly. You can also pick up the |
| 9 | +package files from ftp://ftp.druid.net/pub/distrib/pygresql.pkg.tgz. |
| 10 | +There is also a package in the FreeBSD ports collection but as I write |
| 11 | +this it is at version 2.1. I will try to get that updated as well. |
| 12 | + |
| 13 | +PostgreSQL is a database system derived from Postgres4.2. It conforms |
| 14 | +to (most of) ANSI SQL and offers many interesting capabilities (C |
| 15 | +dynamic linking for functions or type definition, etc.). This package |
| 16 | +is copyright by the Regents of the University of California, and is |
| 17 | +freely distributable. |
| 18 | + |
| 19 | +Python is an interpreted programming language. It is object oriented, |
| 20 | +simple to use (light syntax, simple and straightforward statements), and |
| 21 | +has many extensions for building GUIs, interfacing with WWW, etc. An |
| 22 | +intelligent web browser (HotJava like) is currently under development |
| 23 | +(November 1995), and this should open programmers many doors. Python is |
| 24 | +copyrighted by Stichting S Mathematisch Centrum, Amsterdam, The |
| 25 | +Netherlands, and is freely distributable. |
| 26 | + |
| 27 | +PyGreSQL is a python module that interfaces to a PostgreSQL database. It |
| 28 | +embeds the PostgreSQL query library to allow easy use of the powerful |
| 29 | +PostgreSQL features from a Python script. |
| 30 | + |
| 31 | +I wanted to have DB-SIG API support in the next release but there are |
| 32 | +enough fixes and improvements to make one more release before starting |
| 33 | +on that. The next version will be 3.0 and have the DB-SIG API support. |
| 34 | + |
| 35 | +PyGreSQL 2.3 was developed and tested on a NetBSD 1.3_BETA system. It |
| 36 | +is based on the PyGres95 code written by Pascal Andre, |
| 37 | +andre@chimay.via.ecp.fr. I changed the version to 2.0 and updated the |
| 38 | +code for Python 1.5 and PostgreSQL 6.2.1. While I was at it I upgraded |
| 39 | +the code to use full ANSI style prototypes and changed the order of |
| 40 | +arguments to connect. Later versions are fixes and enhancements to that. |
| 41 | + |
| 42 | +Important changes from PyGreSQL 2.2 to PyGreSQL 2.3: |
| 43 | + - connect.host returns "localhost" when connected to Unix socket |
| 44 | + (torppa@tuhnu.cutery.fi) |
| 45 | + - Use PyArg_ParseTupleAndKeywords in connect() (torppa@tuhnu.cutery.fi) |
| 46 | + - fixes and cleanups (torppa@tuhnu.cutery.fi) |
