Version 6.0.3 (November 2017)

#) Update to `ODPI-C 2.0.3

<https://oracle.github.io/odpi/doc/releasenotes.html#version-2-0-3-tbd>`__.

- Prevent use of unitialized data in certain cases (`issue 77

<https://github.com/oracle/python-cx_Oracle/issues/77>`__).

- Attempting to ping a database earlier than 10g results in error

"ORA-1010: invalid OCI operation", but that implies a response from the

database and therefore a successful ping, so treat it that way!

- Correct handling of conversion of some numbers to NATIVE_FLOAT.

- Prevent use of NaN with Oracle numbers since it produces corrupt data

(`issue 91 <https://github.com/oracle/python-cx_Oracle/issues/91>`__).

- Verify that Oracle objects bound to cursors, fetched from cursors, set in

object attributes or appended to collection objects are of the correct

type.

- Correct handling of NVARCHAR2 when used as attributes of Oracle objects

or as elements of collections.

#) Ensure that a call to setinputsizes() with an invalid type prior to a call

to executemany() does not result in a type error, but instead gracefully

ignores the call to setinputsizes() as required by the DB API

(https://github.com/oracle/python-cx_Oracle/issues/75).

#) Check variable array size when setting variable values and raise

IndexError, as is already done for getting variable values.
