HISTORY.txt

-Changes from 2.0 to 2.0.1
- 1) Removed memory leak that occurred when binding parameters to a cursor;
-    thanks to Robert Ritchie and Don Reid for discovering this.
- 2) Remove the password from the DSN in order to eliminate potential security
-    leaks.
- 3) Improve performance when logging is disabled or not at level DEBUG by
-    avoiding the entire attempt to log bind variable values.
- 4) Use the size value rather than the length value when defining result set
-    variables since the length value is for the length of the column name;
-    thanks to Heran Quan for the patch.
- 5) Added support for Python 3.2.
-
-Changes from 1.2 to 2.0
- 1) Added support for Python 3.x and Unicode.
- 2) Added support for 64-bit Python installations.
- 3) Added test suites for MySQL, PostgreSQL and SQL Server.
- 4) Added support for cursor nextset().
- 5) Added support for cursor execdirect() which calls SQLExecDirect() instead
-    of SQLExecute() which can be necessary in order to work around bugs in
-    various ODBC drivers.
- 6) Added support for creating variables and for specifying input and output
-    converters as in cx_Oracle.
- 7) Added support for deferred type assignment for cursor executemany() as in
-    cx_Oracle.
- 8) Fixed a number of bugs found by testing against various ODBC drivers.
-
-Changes from 1.1 to 1.2
- 1) Added support for time data as requested by Dmitry Solitsky.
- 2) Added support for Python 2.4 as requested by Lukasz Szybalski.
- 3) Added support for setting the autocommit flag in the connection constructor
-    since some drivers do not support transactions and raise a "driver not
-    capable" exception if any attempt is made to turn autocommit off; thanks to
-    Carl Karsten for working with me to resolve this problem.
- 4) Added support for calculating the size and display size of columns in the
-    description attribute of cursors as requested by Carl Karsten.
- 5) Use SQLFreeHandle() rather than SQLCloseCursor() since closing a cursor in
-    the ODBC sense is not the same as closing a cursor in the DB API sense and
-    caused strange exceptions to occur if no query was executed before calling
-    cursor.close().
- 6) Added additional documentation to README.txt as requested by Lukasz
-    Szybalski.
- 7) Tweaked setup script and associated configuration files to make it easier
-    to build and distribute; better support for building with cx_Logging if
-    desired.
-
-Changes from 1.0 to 1.1
- 1) Added support for determining the columns, column privileges, foreign keys,
-    primary keys, procedures, procedure columns, tables and table privileges
-    available in the catalog as requested by Dmitry Selitsky.
- 2) Added support for getting/setting the autocommit flag for connections.
- 3) Added support for getting/setting the cursor name which is useful for
-    performing positioned updates and deletes (as in delete from X where
-    current of cursorname).
- 4) Explicitly set end of rows when SQL_NO_DATA is returned from SQLFetch() as
-    some drivers do not properly set the number of rows fetched.
