      * Bug fix for DateTimeInterval extraction on Pg

1.64    Mon Jul  1 10:20:43 PDT 2013

  No changes since 1.63_03.  Simply a non-dev release of everything since 1.63.

1.63_03 Fri Jun 14 13:11:01 PDT 2013

  Ruslan Zakirov:
      * warn when rollback and commit are mixed
      * Handle->NullsOrder
      * skip timezone tests on SQLite when tzinfo is not there
      * skip tests if mysql can not do timezones
      * DISTINCT argument in Join method
      * DISTINCT argument in Join and NewAlias

  Thomas Sibley:
      * Reset the iterator position whenever a search is run
      * Return the correct record from ->Last instead of the first record
      * Document the caveat of using GotoItem with a non-zero N

1.63_02 Wed Apr 17 18:47:31 MSK 2013

* _Set now can take undef as argument to mean default or NULL.
  Still may result in error if default is not defined and no_nulls
  is true for the column. If old behaviour is required set
  $record->{'no_undefs_in_set'} to true value.

* FUNCTION argument is now allowed in Limit. Code to combine
  FUNCTION, ALIAS and FIELD was refactored and unified in one
  place - CombineFunctionWithField method. Used in Column, GroupBy
  and Limit. This change should be backwards compatible.

* Handle->DateTimeIntervalFunction

1.63_01    Wed Mar 27 13:02:35 PDT 2013

* IN and NOT IN operators in ->Limit method
* Add an AdditionalColumn method to collections
* Add an AS parameter to Column method in collections
* Consistent query generation by sorting hash keys/values

1.63 Fri Sep 14 2012 01:19:38 GMT+0400 (MSK)

* joins_are_distinct hint to indicate that distinct is not
  required for the current set of joins.

1.62 Mon Mar 26 09:31:05 UTC 2012

* Bind values were ignored in SimpleUpdateFromSelect
