+
+<p><b>3.50 19 May 2003</b></p>
+<p>Fixed mssql compat with FreeTDS. FreeTDS does not implement mssql_fetch_assoc().
+<p>Merged back connection and recordset code into adodb.inc.php.
+<p>ADOdb sessions using oracle clobs contributed by achim.gosse#ddd.de. See adodb-session-clob.php.
+<p>Added /s modifier to preg_match everywhere, which ensures that regex does not
+ stop at /n. Thx Pao-Hsi Huang.
+<p>Fixed error in metacolumns() for mssql.
+<p>Added time format support for SQLDate.
+<p>Image => B added to metatype.
+<p>MetaType now checks empty($this->blobSize) instead of empty($this).
+<p>Datadict has beta support for informix, sybase (mapped to mssql), db2 and generic
+ (which is a fudge).
+<p>BlobEncode for postgresql uses pg_escape_bytea, if available. Needed for compat
+ with 7.3.
+<p>Added $ADODB_LANG, to support multiple languages in MetaErrorMsg().
+<p>Datadict can now parse table definition as declarative text.
+<p>For DataDict, oci8 autoincrement trigger missing semi-colon. Fixed.
+<p>For DataDict, when REPLACE flag enabled, drop sequence in datadict for autoincrement
+ field in postgres and oci8.s
+<p>Postgresql defaults to template1 database if no database defined in connect/pconnect.
+<p>We now clear _resultid in postgresql if query fails.
+<p><b>3.40 19 May 2003</b></p>
+<p>Added insert_id for odbc_mssql.
+<p>Modified postgresql UpdateBlobFile() because it did not work in safe mode.
+<p>Now connection object is passed to raiseErrorFn as last parameter. Needed by
+ StartTrans().
+<p>Added StartTrans() and CompleteTrans(). It is recommended that you do not modify
+ transOff, but use the above functions.
+<p>oci8po now obeys ADODB_ASSOC_CASE settings.
+<p>Added virtualized error codes, using PEAR DB equivalents. Requires you to manually
+ include adodb-error.inc.php yourself, with MetaError() and MetaErrorMsg($errno).
+<p>GetRowAssoc for mysql and pgsql were flawed. Fix by Ross Smith.
+<p>Added to datadict types I1, I2, I4 and I8. Changed datadict type 'T' to map
+ to timestamp instead of datetime for postgresql.
+<p>Error handling in ExecuteSQLArray(), adodb-datadict.inc.php did not work.
+<p>We now auto-quote postgresql connection parameters when building connection
+ string.
+<p>Added session expiry notification.
+<p>We now test with odbc mysql - made some changes to odbc recordset constructor.
+<p>MetaColumns now special cases access and other databases for odbc.
+<p><b>3.31 17 March 2003</b></p>
+<p>Added row checking for _fetch in postgres.
+<p>Added Interval type to MetaType for postgres.
+<p>Remapped postgres driver to call postgres7 driver internally.
+<p>Adorecordset_array::getarray() did not return array when nRows >= 0.
+<p>Postgresql: at times, no error message returned by pg_result_error() but error
+ message returned in pg_last_error(). Recoded again.
+<p>Interbase blob's now use chunking for updateblob.
+<p>Move() did not set EOF correctly. Reported by Jorma T.
+<p>We properly support mysql timestamp fields when we are creating mysql tables
+ using the data-dict interface.
+<p>Table regex includes backticks character now.
+<p><b>3.30 3 March 2003</b></p>
+<p>Added $ADODB_EXTENSION and $ADODB_COMPAT_FETCH constant.
+<p>Made blank1stItem configurable using syntax "value:text" in GetMenu/GetMenu2.
+ Thx to Gabriel Birke.
+<p>Previously ADOdb differed from the Microsoft standard because it did not define
+ what to set $this->fields when EOF was reached. Now at EOF, ADOdb sets $this->fields
+ to false for all databases, which is consist with Microsoft's implementation.
+ Postgresql and mysql have always worked this way (in 3.11 and earlier). If you
+ are experiencing compatibility problems (and you are not using postgresql nor
+ mysql) on upgrading to 3.30, try setting the global variables $ADODB_COUNTRECS
+ = true (which is the default) and $ADODB_FETCH_COMPAT = true (this is a new
+ global variable).
+<p>We now check both pg_result_error and pg_last_error as sometimes pg_result_error
+ does not display anything. Iman Mayes
+<p> We no longer check for magic quotes gpc in Quote().
+<p> Misc fixes for table creation in adodb-datadict.inc.php. Thx to iamsure.
+<p> Time calculations use adodb_time library for all negative timestamps due to
+ problems in Red Hat 7.3 or later. Formerly, only did this for Windows.
+<p> In mssqlpo, we now check if $sql in _query is a string before we change ||
+ to +. This is to support prepared stmts.
+<p> Move() and MoveLast() internals changed to support to support EOF and $this->fields
+ change.
+<p> Added ADODB_FETCH_BOTH support to mssql. Thx to Angel Fradejas afradejas#mediafusion.es
+<p> We now check if link resource exists before we run mysql_escape_string in
+ qstr().
+<p> Before we flock in csv code, we check that it is not a http url.
+<p><b>3.20 17 Feb 2003</b></p>
+<p>Added new Data Dictionary classes for creating tables and indexes. Warning
+ - this is very much alpha quality code. The API can still change. See adodb/tests/test-datadict.php
+ for more info.
+<p>We now ignore $ADODB_COUNTRECS for mysql, because PHP truncates incomplete
+ recordsets when mysql_unbuffered_query() is called a second time.
+<p>Now postgresql works correctly when $ADODB_COUNTRECS = false.
+<p>Changed _adodb_getcount to properly support SELECT DISTINCT.
+<p>Discovered that $ADODB_COUNTRECS=true has some problems with prepared queries
+ - suspect PHP bug.
+<p>Now GetOne and GetRow run in $ADODB_COUNTRECS=false mode for better performance.
+<p>Added support for mysql_real_escape_string() and pg_escape_string() in qstr().
+<p>Added an intermediate variable for mysql _fetch() and MoveNext() to store fields,
+ to prevent overwriting field array with boolean when mysql_fetch_array() returns
+ false.
+<p>Made arrays for getinsertsql and getupdatesql case-insensitive. Suggested by
+ Tim Uckun" tim#diligence.com
+<p><b>3.11 11 Feb 2003</b></p>
+<p>Added check for ADODB_NEVER_PERSIST constant in PConnect(). If defined, then
+ PConnect() will actually call non-persistent Connect().
+<p>Modified interbase to properly work with Prepare().
+<p>Added $this->ibase_timefmt to allow you to change the date and time format.
+<p>Added support for $input_array parameter in CacheFlush().
+<p>Added experimental support for dbx, which was then removed when i found that
+ it was slower than using native calls.
+<p>Added MetaPrimaryKeys for mssql and ibase/firebird.
+<p>Added new $trim parameter to GetCol and CacheGetCol
+<p>Uses updated adodb-time.inc.php 0.06.
+<p><b>3.10 27 Jan 2003</b>
+<p>Added adodb_date(), adodb_getdate(), adodb_mktime() and adodb-time.inc.php.
+<p>For interbase, added code to handle unlimited number of bind parameters. From
+ Daniel Hasan daniel#hasan.cl.
+<p>Added BlobDecode and UpdateBlob for informix. Thx to Fernando Ortiz.
+<p>Added constant ADODB_WINDOWS. If defined, means that running on Windows.
+<p>Added constant ADODB_PHPVER which stores php version as a hex num. Removed
+ $ADODB_PHPVER variable.
+<p>Felho Bacsi reported a minor white-space regular expression problem in GetInsertSQL.
+<p>Modified ADO to use variant to store _affectedRows
+<p>Changed ibase to use base class Replace(). Modified base class Replace() to
+ support ibase.
+<p>Changed odbc to auto-detect when 0 records returned is wrong due to bad odbc
+ drivers.
+<p>Changed mssql to use datetimeconvert ini setting only when 4.30 or later (does
+ not work in 4.23).
+<p>ExecuteCursor($stmt, $cursorname, $params) now accepts a new $params array
+ of additional bind parameters -- William Lovaton walovaton#yahoo.com.mx.
+<p>Added support for sybase_unbuffered_query if ADODB_COUNTRECS == false. Thx
+ to chuck may.
+<p>Fixed FetchNextObj() bug. Thx to Jorma Tuomainen.
+<p>We now use SCOPE_IDENTITY() instead of @@IDENTITY for mssql - thx to marchesini#eside.it
+<p>Changed postgresql movenext logic to prevent illegal row number from being
+ passed to pg_fetch_array().
+<p>Postgresql initrs bug found by "Bogdan RIPA" bripa#interakt.ro $f1 accidentally
+ named $f
+<p><b>3.00 6 Jan 2003</b>
+<p>Fixed adodb-pear.inc.php syntax error.
+<p>Improved _adodb_getcount() to use SELECT COUNT(*) FROM ($sql) for languages
+ that accept it.
+<p>Fixed _adodb_getcount() caching error.
+<p>Added sql to retrive table and column info for odbc_mssql.
+<p><strong>2.91 3 Jan 2003</strong>
+<p>Revised PHP version checking to use $ADODB_PHPVER with legal values 0x4000,
+ 0x4050, 0x4200, 0x4300.
+<p>Added support for bytea fields and oid blobs in postgres by allowing BlobDecode()
+ to detect and convert non-oid fields. Also added BlobEncode to postgres when
+ you want to encode oid blobs.
+<p>Added blobEncodeType property for connections to inform phpLens what encoding
+ method to use for blobs.
+<p>Added BlobDecode() and BlobEncode() to base ADOConnection class.

+<p>Speedup of odbc non-SELECT sql statements.
+<p>Added support in MetaColumns for Wide Char types for ODBC. We halve max_length
+ if unicode/wide char.
+<p>Added 'B' to types handled by GetUpdateSQL/GetInsertSQL.
+<p>Fixed warning message in oci8 driver with $persist variable when using PConnect.
+<p><b>2.90 11 Dec 2002</b>
+<p>Mssql and mssqlpo and oci8po now support ADODB_ASSOC_CASE.
+<p>Now MetaType() can accept a field object as the first parameter.
+<p>New $arr = $db->ServerInfo( ) function. Returns $arr['description'] which
+ is the string description, and $arr['version'].
+<p>PostgreSQL and MSSQL speedups for insert/updates.
+<p> Implemented new SetFetchMode() that removes the need to use $ADODB_FETCH_MODE.
+ Each connection has independant fetchMode.
+<p>ADODB_ASSOC_CASE now defaults to 2, use native defaults. This is because we
+ would break backward compat for too many applications otherwise.
+<p>Patched encrypted sessions to use replace()

+<p>Moved ADOConnection to adodb-connection.inc.php and ADORecordSet to adodb-recordset.inc.php.
+ This allows us to use doxygen to generate documentation. Doxygen doesn't like
+ the classes in the main adodb.inc.php file for some mysterious reason.
+<p><b>2.50, 14 Nov 2002</b>
+<p>Added transOff and transCnt properties for disabling (transOff = true) and
+ tracking transaction status (transCnt>0).

+<p>Fixed postgresql inconsistencies in date handling.
+<p>Added support for mssql_fetch_assoc.
+<p>Fixed $ADODB_FETCH_MODE bug in odbc MetaTables() and MetaPrimaryKeys().
+<p>Accidentally declared UnixDate() twice, making adodb incompatible with php
+ 4.3.0. Fixed.
+<p>Fixed pager problems with some databases that returned -1 for _currentRow on
+ MoveLast() by switching to MoveNext() in adodb-lib.inc.php.
+<p>Also fixed uninited $discard in adodb-lib.inc.php.

+<p>Rewrote pivoting code.
+<p><b>2.42, 4 Oct 2002</b></p>
+<p>Fixed ibase_fetch() problem with nulls. Also interbase now does automatic blob
+ decoding, and is backward compatible. Suggested by Heinz Hombergs heinz#hhombergs.de.

+ suggested by Heinz Hombergs.
+<p>PageExecute() does not rewrite queries if SELECT DISTINCT is used. Requested
+ by hans#velum.net

+<p>Revised pivottable.inc.php code. Added better support for aggregate fields.
+<p>Fixed mysql text/blob types problem in MetaTypes base class - thx to horacio
+ degiorgi.
+<p>Added SQLDate($fmt,$date) function, which allows an sql date format string
+ to be generated - useful for group by's.
+<p>Fixed bug in oci8 SelectLimit when offset>100.
+<p><b>2.40 4 Sept 2002</b></p>
+<p>Added new NLS_DATE_FORMAT property to oci8. Suggested by Laurent NAVARRO ln#altidev.com

+<p>Fixed interbase replaceQuote for dialect != 1. Thx to "BEGUIN Pierre-Henri
+ - INFOCOB" phb#infocob.com.
+<p>Added white-space check to QA.
+<p>Changed unixtimestamp to support fractional seconds (we always round down/floor
+ the seconds). Thanks to beezly#beezly.org.uk.
+<p>Now you can set the trigger_error type your own user-defined type in adodb-errorhandler.inc.php.
+ Suggested by Claudio Bustos clbustos#entelchile.net.
+<p>Added recordset filters with rsfilter.inc.php.
+<p>$conn->_rs2rs does not create a new recordset when it detects it is of type
+ array. Some trickery there as there seems to be a bug in Zend Engine
+<p>Added render_pagelinks to adodb-pager.inc.php. Code by "Pablo Costa" pablo#cbsp.com.br.
+<p>MetaType() speedup in adodb.inc.php by using hashing instead of switch. Best
+ performance if constant arrays are supported, as they are in PHP5.
+<p>adodb-session.php now updates only the expiry date if the crc32 check indicates
+ that the data has not been modified.
+<p><b>2.31 20 Aug 2002</b></p>
+<p>Made changes to pivottable.inc.php due to daniel lucuzaeu's suggestions (we sum the pivottable column if desired).
+<p>Fixed ErrorNo() in postgres so it does not depend on _errorMsg property.
+<p>Robert Tuttle added support for oracle cursors. See ExecuteCursor().
+<p>Fixed Replace() so it works with mysql when updating record where data has not changed. Reported by
+Cal Evans (cal#calevans.com).
+<p><b>2.30 1 Aug 2002</b></p>
+<p>Added pivottable.inc.php. Thanks to daniel.lucazeau#ajornet.com for the original

+<p>Fixed mssql SelectLimit( ) bug when distinct used.
+<p><b>2.30 1 Aug 2002</b></p>
+<p>New GetCol() and CacheGetCol() from ross#bnw.com that returns the first field as a 1 dim array.
+<p>We have an empty recordset, but RecordCount() could return -1. Fixed. Reported by "Jonathan Polansky" jonathan#polansky.com.

+<p>Now default adodb error handlers ignores error if @ used.
+<p>If you set $conn->autoRollback=true, we auto-rollback persistent connections for odbc, mysql, oci8, mssql.
+Default for autoRollback is false. No need to do so for postgres.
+As interbase requires a transaction id (what a flawed api), we don't do it for interbase.

+ for an example of usage.
+ <p>Added UpdateBlobFile() for uploading files to a database.
+ <p>Made UpdateBlob() compatible with oci8po driver.
+ <p>Added noNullStrings support to oci8 driver. Oracle changes all ' ' strings to nulls,
+ so you need to set strings to ' ' to prevent the nullifying of strings. $conn->noNullStrings = true;
+ will do this for you automatically. This is useful when you define a char column as NOT NULL.
+ <p>Fixed UnixTimeStamp() bug - wasn't setting minutes and seconds properly. Patch from Agusti Fita i Borrell agusti#anglatecnic.com.

+<P>Gam3r spotted that a global variable was undefined in the session handler.
+<p>Mssql date regex had error. Fixed - reported by Minh Hoang vb_user#yahoo.com.
+<p>DBTimeStamp() and DBDate() now accept iso dates and unix timestamps. This means

+<p><b>1.62 11 Dec 2001</b></p>
+<p>Major speedup of ADOdb for low-end web sites by reducing the php code loading and compiling
+cycle. We conditionally compile not so common functions.
+Moved csv code to adodb-csvlib.inc.php to reduce adodb.inc.php parsing. This file
+is loaded only when the csv/proxy driver is used, or CacheExecute() is run.
+Also moved PageExecute(), GetSelectSQL() and GetUpdateSQL() core code to adodb-lib.inc.php.
+This reduced the 70K main adodb.inc.php file to 55K, and since at least 20K of the file
+is comments, we have reduced 50K of code in adodb.inc.php to 35K. There
+ should be 35% reduction in memory and thus 35% speedup in compiling the php code for the
+main adodb.inc.php file.
+<p>Highly tuned SelectLimit() for oci8 for massive speed improvements on large files.
+Selecting 20 rows starting from the 20,000th row of a table is now 7 times faster.
+Thx to Tomas V V Cox.
+<p>Allow . and # in table definitions in GetInsertSQL and GetUpdateSQL.
+ See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.
+<p>Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This determines the number
+of records to prefetch in a SELECT statement. Only used by oci8.</p>
+<p>Added high portability Oracle class called oci8po. This uses ? for bind variables, and
+lower cases column names.</p>
+<p>Now all database drivers support $ADODB_FETCH_MODE, including interbase, ado, and odbc:
+ADODB_FETCH_NUM and ADODB_FETCH_ASSOC. ADODB_FETCH_BOTH is not fully implemented for all
+database drivers.
+<p><b>1.61 Nov 2001</b></p>
