    Updates and additions to release 3.6

    details found here (http://www.tryton.org/posts/new-tryton-release-36.html)

    Major changes for the developer

        It is now allowed to have many times the same field in list/tree view.
        There is no more a datetime widget for list/tree, two columns with one
        widget date and one widget time should be used instead.

        A new field TimeDelta appears in this release to represent a duration. It
        replace the float_time widget which had some rounding issue. This new
        field is already used in the timesheet and project modules.

        The One2Many widget can be configured to use a Cartesian product with the
        selections of many values for Many2One or Reference fields.

        A method restore_history_before is added to ModelSQL which behaves like
        the existing restore_history but restore the records just before the \ 
datetime.

        The on_change methods have been migrated to a behaviour more consistent
        with the Active Record Pattern used in Tryton. Instead of returning a
        dictionary with the values to change, now the instance is directly changed.

        This allow to chain easily the on_change methods or reuse them in other
        methods reducing the duplication.

        The method save on ModelStorage is now a dualmethod which means that it
        can be called as usual as an instance method but also as a class method
        with a list of records. Saving many records at once this way improves the
        performance as the method will minimize the number of queries to the
        database and will validate the result by bunch.

        The Dict field received a translated method to create descriptors which
        translate the values or the keys like the same method on Selection field.

        It is now allowed to use the dotted notation in the order clause of a search.
        The ORM will automatically generate the needed joins.

        The API of the Report class has been reworked to improve the customization
        of the engine. The formatting methods are now more strict to prevent silent
        failure.

        The safe_eval (which was not sure to be safe) has been completely removed.
        In the places where the evaluated code was any way safe, the standard eval
        is used. For evaluated code from outside, a JSON notation is now used. Some
        utilities have been developed to ease the creation of JSON from XMl or in
        the views.

        A new kind of button has been added which works on non-saved record. They
        are quite similar to on_change but they are triggered by a click on a
        button instead of a change of field.

    Accounting

        A new method reverse_compute has been added to Tax which allow to compute
        the base amount from the taxed amount.
        The sign of the second currency amount is enforced to be the same as
        debit - credit.
        The analytic account management has been reworked to use a really One2Many
        instead of the pseudo-field. This simplification was possible thanks to the
        recent new features like the usage of Reference field on One2Many.

    Party

        The vat number is now stored in its compact format.

    Product

        The number of decimal for internal price calculations is now a configuration
        parameter price_decimal. This parameter is used everywhere to ensure
        consistency between all modules.

    Purchase/Sale

        Their lines support both mixed invoice type (Invoice vs Credit Note) per
        line when computing the invoiced quantity.

    Stock

        A new state staging is added to the move. Such state doesn't impact at all
        the computation of the stock level. It is used for supply on sale, to
        create moves in advance.
        Inactive products are still computed for the stock level.
        The computation of assigned move has been improved to take only in
        consideration outgoing move assigned not the incoming. This result in a
        less optimistic for the stock level and thus prevent to assign a move with
        an incoming one that is just assigned but not yet done.
        Forecasts are now automatically deactivated when their period is in the past.
