	(b2b2748f7f88)
	* Fix issue 118 ("datetime conversion to sql is not converting
	sub-seconds correctly") - Pad microseconds to 3 digits so it gets
	converted correctly. Thanks, Ken Robbins (kenneth.robbins at gmail)!
	(5d0c980ef8b8)
	* Make tests/test_queries.py actually run tests. It looked like it was
	half-finished and not working. This fills it out and makes it work and
	actually test a few things. (5373541eb899)
	* setup.py: Make it possible to use `python setup.py test`
	(3c32acb41251)

	fe6cb9aa5120, 446f0005e638, e8d4b19d87b1, 90b2aa2ea01f, 7bb29af4b22c)
	* Add `pymssql.get_dbversion` function that wraps the dbversion
	function in FreeTDS. (1158a5d2be9c)

	* Fix issue 109 ("Failure to pass Unicode characters to callproc;
	failing test:
	tests.test_sprocs.TestCallProcFancy.testCallProcWithUnicodeStringWithRussianCharacters"):
	Skip test because it fails with some versions of FreeTDS but passes
	with others. (d05341273673)
	* Fix issue 116 ("A few tests fail if running on a system that has SQL
	Server available on port 1433") (0fc4086447fe)
	* Modify tests/test_config.py to use server='dontnameyourserverthis'
	when doing various tests so it doesn't try to connect to a SQL
	Server listening on localhost:1433 (0fc4086447fe)
	* tox.ini: Add {posargs:-w tests -v} to nosetests invocation so that
	we can pass arguments to tox -- e.g.: to run only specific tests
	(a105878d500d)
	* tox.ini: Add "ipdb" to deps, because the IPython debugger is very
	nice for debugging why tests are failing (be9ee40156cb)
	* Fix issue 114 ("Fix SP name handling in threaded test so we can
	actually run it.") (6ac2b75747ad)
	* Fix issue 100 (Error when executing setup.py {build,develop} on a
	system with no setuptools: "name 'STDevelopCmd' is not defined")
	(5222ee37b2ab)

	tests/run_sqlalchemy_tests.py for running the SQLAlchemy test suite
	with pymssql using the server configured in tests/tests.cfg
	(999d9dbe791b)
	* Fix issue 92 ("Cursor fetch* methods return redundant keys for
	column names and column numbers.") (08ae783880dd)
	* tests/test_connection_as_dict.py:
	bug 18 ("FetchAll fails to return rows when running against a
	connection instantiated with as_dict=True."): Add a test which
	illustrates that the issue is resolved. (058d761cc761)
	* Fix issue 60 ("cursor.execute raise UnicodeDecodeError if query and
	params in unicode"): Add patch from tonal.promsoft and add tests.
	(49210c03a6cf)
	* Add *.c to MANIFEST.in so they get included in sdist and end-users
	don't need to run Cython. (25c1a84aac0c)
	* Fix issue 56 ("callproc do not accept None and unicode string in
	parameters"): Add patch from tonal.promsoft and add tests
	(939eb7939136)
  * version 2.0.0b1-dev-20130403

Tue Dec 27 15:14:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>
	* mssqldbmodule.c: bug fixes, improvements and cleanups:
	  + implemented set_login_timeout() and set_query_timeout() functions;
	  + eliminated unnecessary ODBC code
	  + cleaned up exception code and improved exception handling,
		SF bug #1335560
	  + web page now correctly mentions FreeTDS 0.63 as the minimal
		required version
	  + stdmsg() method is now deprecated; all errors are concatenated
		in errmsg()
	  + implemented min_error_severity: all errors at or above that
		level will raise the exception; if the severity is lower, they
		will just accumulate in errmsg()
	  + added setting coltype to NUMBER for float types (found by
		Jakub Labath)
	* setup.py:
	  + reincarnated ntwdblib.dll which turned out to be redistributable
		after all; pymssql includes the latest version that allows
		connecting to SQL 2005; eliminated some stupid notes from the
		web page and will ease set up process for users
	* apitest_mssql.py: new file
	  + provided by Jakub Labath, this file performs some basic DB-API
		compliance tests; it immediately triggered the unicode bug
	* version 0.7.4

Sat Oct 22 19:41:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>
	* mssqldbmodule.c: multithreading improvements - from now on pymssql
	  is thread-safe, it releases GIL in proper places; idea and initial
	  patch by John-Peter Lee (thanks very much!)

Mon Sep 5 23:29:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>
	* setup.py: fixed an installation issue regarding importing pymssql
	  that imports _mssql which isn't installed, and blows up with
	  AttributeError... (thanks Vsevolod Stakhov)
	* version 0.7.3

Mon Sep 5 00:32:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>
	* version 0.7.2

Sun Sep 4 23:12:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	* mssqldbmodule.c: improvements and cleanups:
	  + improved error handling: if the db function fails, the exception
		is thrown automatically and immediately; no need to check
		return value of conn.query(), just catch _mssql.error
	  + improved error handling: it is possible that MS SQL calls message
		handler twice; now _mssql catches and reports both of them at once
	  + improved error handling: in some cases _mssql.query() returns
		success but the results are invalid; now it is handled properly
		(example "SELECT CAST(1234.5678 AS NUMERIC(4,2))")
	  + added proper connection initialization: a number of SET statements
		are executed upon connection setup to set sensible SQL behaviour;
		see source for details; one needs to unset them if needed
	  + implemented min_{message|error}_severity as it is in php_mssql
		to ignore unimportant errors; it's work in progress
	  + new function rmv_lcl() initially by Mark Pettit, to strip locale
		crap from MONEY values converted to SQLCHAR while generating
		Decimal object
	  + other small fixes, improvements and janitorial work

Tue Aug 30 00:16:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	* mssqldbmodule.c: new features:
	  + large numbers (DECIMAL, NUMERIC, MONEY, SMALLMONEY) are returned
		as Decimal object -- this helps maintain accuracy; thanks to
		Mark Pettit for help
	  + COMPUTE clauses are supported (it wouldn't fetch data for those
		columns before)
	  + ROWID type has been removed from _mssql module
	  + new type DECIMAL to denote Decimal objects in result set

Mon Aug 29 21:59:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	* mssqldbmodule.c: some improvements:
	  + BIT values are returned as Python bool objects, suggested by
		Mark Pettit
	  + close() method returns None on success (not to be used at all)
		and throws exception on error
	  + fixed use of uninitialized value when parsing SMALLDATETIME
	  + another round of performance improvements in GetRow() - eliminated
		unnecessary data conversions and unneeded DB-Lib calls
	  + janitorial fixes

Mon Aug 22 04:35:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	* mssqldbmodule.c: massive diff:
	  + fixed bug with fetching query results of some data types;
		found by Mark Pettit
	  + fixed IndexError when query returns no rows; patch by Jakub Labath
	  + rewritten function GetRow() that fetches query results: performance
		improvements, better handling of result data types; datetime
		is returned as datetime object instead of string (it's more
		consistent with other values -- and more pythonic :)
	  + eliminated DetermineRowSize()
	  + cleanups: _mssql_init() further improvements w.r.t. Python API
	  + janitorial fixes
	  + added licensing information
	* pymssql.py: docstring changed to look nicer with help()
	* version 0.7.2

Thu Aug 11 02:12:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	* mssqldbmodule.c: improved module init function: added doc string,
	  made compliant with Python 2.0+ module interface (there are no more
	  coredumps on help())
	* mssqldbmodule.c: documented that _mssql.connect() is not portable
	  between FreeTDS-dependent platforms and Windows platforms; documented
	  host:port usage

Sat Jul 23 14:20:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	* mssqldbmodule.c: eliminated problems with Python exiting upon
	  invalid login credentials with FreeTDS - the culprit was INT_EXIT
	  and FreeTDS setting DBDEAD
	* mssqldbmodule.c: added better error messages (esp. on Windows)
	* mssqldbmodule.c: added msg_handler and err_handler debugging
	* 0.7.1 packages re-released

Fri Jul 22 03:19:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>

	  more builtin Python features; some redundant code removed; memset()
	  removed as there were no benefits but performance decrease
	* mssqldbmodule.c: help(_mssql) works; help for conn object works too
	* pymssql.py: _quote: removed escaping backslash -- with MSSQL it is
	  only needed to escape single quotes by duplicating them
	* pymssql.py: pymssqlCnx class: added a few checks to properly support
	  DB-API 2.0 (see .close() in PEP 249)
	* version 0.7.1

Wed Jul 20 22:12:00 2005  Andrzej Kukula <akukula@users.sourceforge.net>
