       and a bytea type and LO type are recognized.

    [Feature of Driver7.3.025x]

    1. Correspondence protocol 3
       Options, such as client encoding, are set up by the start-up packet.
       This makes the most of the mechanism of Parse/Bind/Execute.
       .The outfit of SQLDescribeParam
       .PREPARE/EXECUTE is changed from the command base to the protocol base.
       .FETCH command is changed to an Execute request as it has come out.
       .Moreover, bytea and lo type coexistence is possible.
       .Others...

    2. Enhancement in declare/fetch mode (7.4 or later)
       Even if a certain renewal occurs on the way by holdable cursor exploitation,
       a commitment is possible in comfort.
       Moreover, the static update cursor was supported.

2) SQLColumns or SQLColAttribute may return bad answer when Show system tables is turned off
3) adds support for ; delimited options in ConfigDSN
4) fixes problem with binding parameters and SQLCancel without SQLFreeStmt

- Notes: psqlODBC 08.01.0102
Changes:
1) Server side prepare now works correctly.
2) A bug in SQLTables that shows up in Borland SQL Explorer in
3) Declare/Fetch mode has been fixed.
4) A number of inconsistent internal APIs have been cleaned up. These
issues only showed up on some OS's.
5) Correct value returned by SQLGetInfo for
SQL_CATALOG_LOCATION/SQL_QUALIFIER_LOCATION. This prevented use of the
driver in Visual Studio 2005.
The last four numbers will represent the build. If the last 2 digits are
both zero, a stable version is indicated. If the last two digits are
non-zero, it is a development snapshot.
So, starting with the next stable release, we will have:
08.01.0200 - Stable
08.01.0201 - Development
...
...
08.01.0299 - Development
08.01.0300 - Stable
Of course, we won't necessarily have 99 snaphosts between stable releases!
- Notes: psqlODBC 08.01.0101
Changes:
This release fixes a serious problem in non-declare/fetch mode where
recordsets over the configured declare/fetch cache size were returned
incorrectly. It is advised that all users of v08.01.0100 upgrade as soon
as possible.

## psqlODBC 08.01.0100 Release

This release represents a major change to the driver over previous versions;
in particular, the network code has been replaced with the PostgreSQL libpq
library. This allows us to more easily take advantage of updates and new
features that might be introduced to the PostgreSQL wire protocol, and also
allowed us to upgrade straight away to the version 3 protocol which was
previously unsupported. We were also able to add SSL support, as well as
Kerberos authentication support.
>From this release, two versions of the driver are provided for Windows,
'PostgreSQL ANSI' which supports single and multibyte applications through
the ANSI ODBC API, and 'PostgreSQL Unicode' which provides Unicode support
through the Unicode ODBC API. On Unix systems, the driver type may be
selected via a configure option.
psqlODBC may be downloaded from http://www.postgresql.org/ftp/odbc/versions/
in source, Windows Installer, merge module, and basic zip file formats.
Please post any bug reports to the pgsql-odbc@postgresql.org mailing list.
I'd like to take this opportunity to thank all those involved with the
development, testing and bug fixing of the updated driver.
PostgreSQL Core Team
- Notes: psqlODBC 08.00.0102
This is a bug fix release
of the pre-libpq version of the driver, specifically to fix a bug
affecting Unix users
(http://gborg.postgresql.org/project/psqlodbc/bugs/bugupdate.php?1176)

## psqlODBC 08.00.0100 Release

The driver is available in source form, as well as a dll, merge module
and msi installer for Windows.
Regards, Dave.
- Notes: psqlODBC 08.00.0005
This version
contains a some recent fixes, and is packaged in a new installer built
entirely using open source tools (specifically, the Wix toolkit).
- Notes: psqlODBC 08.00.0002
This version of the driver is a minor update
with a fix to the string sizing code in SQLGetInfo, and removal of the
need for tables to be in the search path or public schema for them to be
returned by SQLTables.
- Notes: psqlODBC 08.00.0001
The purpose of this version is to try to get something stable, with
proper schema/without OID support ready for the 8.0 release
(particularly the win32 release). To that end, this release is mainly a
quick cleanup of the following:
- GUI cleanup. Dialogues should behave better now and not have unlabeled
buttons or move around the screen in strange ways.
- Updateable Cursor support. This is largely experimental and is (I
believe) the cause of a least a couple of stability issues in the recent
snapshots. In this release it is marked 'experimental' on the setup
dialogue (only in English, if anyone can do the Japanese version, please
send a patch) and turned off by default.
I'd appreciate it if ppl could test it a little with Updateable Cursors
*turned off* and report any bugs.

## psqlODBC 07.05.0001

This is version 07.05.0001. For those that don't know or don't recall
how the versioning works, the major and minor number track the latest
release of PostgreSQL that the driver is expected to work with. The
revision number is a bit more complex. The first two digits are the
version number, where even numbers are development versions, and odd are
release. The last two digits are the build number.
In other words, this driver is build 01 of development version 00, and
is expected to work with PostgreSQL 7.5dev. :-) The leading zeros are an
ODBC thing...

## psqlODBC 07.03.0100 Release

I'm pleased to announce the long awaited new version of psqlODBC. This
release represents a major change in the packaging and distribution of
psqlODBC. In particular the following points should be noted:
1) The build number will now be used to indicate both the release number
(first 2 digits), and snapshot build number (last 2 digits). this
release is 0100, or release 1, snapshot 0. The first development
snapshot will become 0101, the second 0102 and so on. The next official
release should be 07.03.0200.
2) With this release, the ODBC 3 driver is now the default. The
filenames, driver names and their capabilities are as follows:
psqlodbc.dll PostgreSQL ODBC3.0 Level
driver
psqlodbc25.dll PostgreSQL Legacy ODBC2.5 Level
driver
psqlodbc30w.dll PostgreSQL Unicode (Beta) Beta quality ODBC3.0
level driver with Unicode support
3) The 3 drivers are no longer self contained. psqlodbc.dll is used as
the setup dll for all three drivers, hence no matter how you
redistribute or install the drivers, you should always include this
file.
In addition, this driver fixes an annoying problem with recent builds of
PostgreSQL on Redhat systems that have a particularly long compiler
version string that caused a buffer overflow resulting in a GPF on
Windows upon connection to the database.
The driver is released under the LGPL, and can be downloaded from the
Downloads page on the website at
http://gborg.postgresql.org/project/psqlodbc/projdisplay.php
