---------------------------------------------------------------------
This file describes changes and or fixes since the last update.


NEW FEATURES:

1. Support for IP Addresses in DataSource Configuration dialog
   (submitted by Jan Kurik, kurik@reax.cz).

2. "Show System Tables" advanced datasource option -- allows you to view
   system tables as regular tables (good in Access).  This automatically
   includes the oid in SQLColumns for Postgres 'pg_' tables.

3. "Extra System Table prefixes" advanced driver option -- allows you to
   specify the prefixes (in addition to 'pg_') that are considered as
   SYSTEM TABLE.  They are separated by a semicolan (;).

   For example, you may have data definition (dd_xxxx and dm_xxxx) tables
   you dont want to see.  Enter "dd_;dm_" in the prefixes box.

4. Finally, correctly implemented the TableType parameter to SQLTables.
   TableType is now parsed to determine what table types to return.
   Thus, you can ask SQLTables for VIEWS only, and just get views.  You
   can ask for SYSTEM TABLE, and just get system tables.  If you ask for
   an unsupported type (i.e., 'GLOBAL TEMPORARY'), it returns nothing.

   This also fixes bugs in the tables display in VC++4.x and VC++5.x


BUG_FIXES:

1. Fixed char precision on manual result sets (SQLTables, SQLColumns).
   It was returning 0, when infact the exact size was known.  VC++4.0 would
   show only the first character of a table name in its class wizard.

2. Fixed problem with SQL_BIT type in where clause.  Used quotes around
   the bool data since there is no operator for "bool and int4".  This
   would cause Access to fail on updates of records with bools in them.

3. Corrected info function for SQL_FETCH_DIRECTION.  It was incorrectly
   ORing the bitmasks together.  Remember though, that SQLExtendedFetch
   is only available if the "Use Cursors" option is not checked, since
   the result set is all in memory and any row can be scrolled to.

4. Corrected info function for SQL_ROW_UPDATES.  It was incorrectly
   returning "Y" when infact, row updates have never been supported
   because keyset-driven and mixed cursors aren't supported anyway.

5. Corrected info function for SQL_SCROLL_CONCURRENCY.  It was incorrectly
   returning SQL_SCCO_OPT_ROWVER when infact, the driver doesn't support
   Positioned Update statements or SQLSetPos.  It now returns
   SQL_SCCO_READ_ONLY (no updates are allowed in scrollable cursors).

6. Corrected info function for SQL_SCROLL_OPTIONS.  It was incorrectly
   returning SQL_SO_KEYSET_DRIVEN when infact, the driver doesn't support
   keyset driven cursors (reading in all the keys of a result set and then
   using the key to retrieve the data dynamically, each time you scroll
   to a given row). So, now it returns one of two things:

   If "Use Cursors" is checked:   (SQL_SO_FORWARD_ONLY)
   If "Use Cursors" not checked:  (SQL_SO_FORWARD_ONLY | SQL_SO_STATIC)

7. Driver handles SQLGet/SetStmtOption better.  It returns the state
   "Driver not Capable" if an option is not supported.  And it returns
   "Option value Changed" state (SQL_SUCCESS_WITH_INFO) if a value is
   not supported and substitutes a suitable value.

   For example, if an application requests a SQL_SO_KEYSET_DRIVEN cursor,
   the driver will substitute a FORWARD_ONLY or a STATIC cursor type,
   depending on the "Use Cursors" option.
