+* $sth->rows() now returns the number of fetched rows, for SELECT, otherwise
+  returns - 1 (unknown).
+
+Aug 18 2000
+* starting a transaction (automatic or not) is more robust, now it reuses an
+  active transaction handle, instead of overridding it with a new one, leaving
+  the previous one "immortal" (because the previous transaction handle is no
+  longer kept!)
+
+Aug 16 2000
+* Fix $dbh->do() method for usage with placeholders.
+* Added support for CursorName attrib
+* more robust commit with AutoCommit on
+
+Aug 13 2000
+* Added datatype values conversion routine between InterBase internal
+  values and DBI/ISO/ANSI/ODBC values

+* Tested to 100% compliant with DBIx::Recordset (0.21)!
+
+Aug 12 2000
+* more informative error message
+* fix ping() method. Now not die if RaiseError => 1
+
+July 29 2000
+* AutoCommit attribute handling:
+
+- in dbd_login6():
+simply turns on imp_dbh->init_commit = 1
+
+- in db_STORE_attrib() :
+if init_commit == 1:
+if AutoCommit turned On: do nothing.
+if AutoCommit turned Off: start a new default transaction, stored in
+imp_dbh->tr
+
+if init_commit == 0:
+if AutoCommit turned On: commit changes.
+if AutoCommit turned Off: start a new default transaction, stored in 
+imp_dbh->tr
+
+Before returning, init_commit is reset to 0.
