-- TActiveRecord::findBySql() will return an object rather than an array
-- TActiveRecord::findAllBySql() will return an array of objects.
-
-Upgrading from v3.1a
----------------------
-- The signature of TActiveRecord::finder() is changed. This affects
- all TActiveRecord-descendant classes that override this method.
- Please use the following code to override the method:
- public static function finder($className=__CLASS__)
- {
- return parent::finder($className);
- }
-
-- The way to specify the table name for an active record class is changed.
- Previously, it used the static class member '_tablename'.
- Now it uses class constant as follows:
- class UserRecord extends TActiveRecord
- {
- const TABLE='users_table';
- }
-
-- Changed TActiveRatingList's javascript control class
- name from "Prado.WebUI.TRatingList" to "Prado.WebUI.TActiveRatingList".
-
-- PRADO's javascript library locations moved from Web/Javascripts/xxx to Web/Javascripts/source/xxx
-
-- IPostBackDataHandler added a new method getDataChanged(). Any control
- implementing this interface will be required to implement this new method.
-
-Upgrading from v3.0.x
----------------------
-- Validators ClientSide.OnSuccess becomes ClientSide.OnValidationSuccess,
-- Validators ClientSide.OnError becomes ClientSide.OnValidationError,
-- Validator OnSuccess event becomes OnValidationSuccess.
-- Validator OnError event becomes OnValidationError.
-- Content enclosed in is now parsed as normal template content.
- Previously, it was not parsed and was rendered as is.

-
-Upgrading from v3.0.6
----------------------
-
-Upgrading from v3.0.5
----------------------
-- TRepeater does not render anymore for empty item template.
-- constructUrl() now encodes ampersand by default. This should have minimal
- impact on any existing PRADO applications, though.
-- TDataGrid does not generate default table styles. This may affect
- the appearance of existing PRADO applications that use TDataGrid.
-- If TUrlMapping is used, you need to set the UrlManager property of
- THttpRequest to the module ID of TUrlMapping.
-- TJavascriptLogger toggle key is changed from ALT-D to ALT-J.
- Use the ToggleKey property chanage to a different key.
-- Javascript Library rico was REMOVED.
-
-Upgrading from v3.0.4
----------------------
-- TFileUpload::saveAs() will return false instead of raising an exception
- if it encounters any error.
-- TDropDownListColumn.DataField is renamed to DataTextField and
- DataFormatString is renamed to DataTextFormatString.
- A new property named DataValueField is added.
