      - The DBI params are now encapsulated in a code reference, rather than
        stored as the passed array, so that the password is less likely to be
        displayed in a dump. Idea borrowed from Rose::DB. Patch from Brad
        Bowman.
      - Eliminated warning about the non-portability of a v-string on older
        Perls. Thanks to Mark Lawrence for the report (Issue #17).
      - Removed a couple of leftover examples of the `catch` feature removed
        in v0.50. Thanks to Randy Stauner for the patch!
      - Eliminated more "Use of qw(...) as parentheses" syntax errors \ 
in tests
        when running on Perl 5.17.
      - Add mention of DBI Callbacks parameter to the docs, as folks often ask
        for this functionality, not realizing that the DBI already provides
        it. Randy Stauner.

      - Fixed internal exception handling on Perls less than 5.14, where some
        exceptions woult not be propagated to the caller.

      - The `catch` functionality has been completely removed. Any `catch`
        block passed to `run()`, `txn()`, or `svp()` will be ignored. Errors
        will trigger fatal exceptions.
      - Removed the `with` method, which was deprecated in 0.34. Use `mode()`
        instead.
      - Fixed bad method call attempted when an `svp()` block failed. Thanks
        to Ricardo SIGNES for the regression test and the fix.
      - Fixed creation of the SQLite driver savepoint methods so that they
        exist and work even if the driver is loaded before DBD::SQLite. Thanks
        to Ricardo SIGNES for the regression test and the fix.
