* `SQLColAttributeW`: `field_identifier` parameter type has been changed to the new `Desc` enumeration.
* `Desc` has been renamed to `Description`.

0.10.0
------

*Breaking Changes*:

* Enum variant names have been shortend and use now idiomatic CamelCasing.
* Type Names now also use idiomatic CamelCasing.
* The `SQL` prefix has been dropped from most type names.
* `InputOutput` has been renamed to `ParamType`. As the names of the enumeration should be derived of the Prefix of the associated constants in the C Headers.
* Enumerations which have been casted from integers are now newtypes in order to prevent undefined behaviour in case the enum is not complete or the driver/driver manager is not ODBC conform.
  * `SqlReturn` is now a newtype i16 with predifined constants and is now named `Return`.
  * `Nullable` is now a newtype i16 with predefined constants.
  * `interval_type` in `IntervalStruct` has been changed from `Interval` to `c_int`.

0.9.0
-----

* Adds `attributes::SQL_ATTR_CONNECTION_POOLING` and `attributes::SQL_ATTR_CP_MATCH` enums
* Implements Default trait for attribute values

* *Breaking Change*: `SQL_ATTR_APPLICATION_KEY` constant removed because it is not part of the ODBC standard.
If there is any software that depends on this constant defined, users are encouraged to open an
issue report
* *Breaking Change*: `SQL_OV_ODBC_2` constant removed because odbc-sys does not support OBDC versions < 3.0.
* *Breaking Change*: Enum OdbcVersion renamed to `SQL_ATTR_ODBC_VERSION` to better reflect it's intended use as a value
for environment attribute to be used with `SQLSetEnvAttr` and `SQLGetEnvAttr` functions
