### Version 0.5.3.0 (2017-05-15)
  * Refactored some rudimentary cursor handling code out of the
    implementation of the fold operators,  into a new
    `Database.PostgreSQL.Simple.Cursor` module,  thanks to Bardur Arantsson.

  * Made the `FromField` instance for `Char` compatible with
    postgresql's `bpchar` type.  Thanks to Ivan Lazar Miljenovic for
    reporting the issue.

  * Added `Show` and `Eq` instances for `Notification`, thanks to
    Matvey Aksenov.

  * Fixed some example code, thanks to Matvey Aksenov.

  * Fixed a problem with using `conversionError` to throw exceptions
    of type `SomeException`.  Previously, the exception would be
    wrapped in a second `SomeException` dynamic constructor which
    would cause normal GHC typecase idioms over `SomeException` to fail.
