Update to 3.5.0:

Version 3.5.0  Released January 6, 2015

  - Allow "placeholder escaping" by the use of a backslash directly \ 
before it, e.g.
    "SELECT 1 FROM jsontable WHERE foo \\? ?"
    will contain a single placeholder, and the first question mark will be sent \ 
directly
    to the backend to be parsed as an operator.
    [Greg Sabino Mullane, Tim Bunce]
    (CPAN bug #101030)

  - Improve the workings of the ping() method, so it always tests for
    a valid database backend and returns the correct true/false.
    [Greg Sabino Mullane, with help from Andrew Gierth and Tim Bunce]
    (CPAN bug #100648)

  - Add get_info(9000) => 1 to indicate driver can escape placeholders.
    [Tim Bunce]

  - In tests, force the client_encoding to UTF8, skip tests that involve
    characters not supported by the server_encoding
    [Dagfinn Ilmari Mannsåker <ilmari@ilmari.org>]

  - Fix memory leak when selecting from arrays
    [Dagfinn Ilmari Mannsåker, reported by Krystian Samp]

  - Make get_info much more efficient and slightly simpler.
