-- Added a `ScaleToFit` element - scales it child down so it does fit in the provided space,
+- Introduced new element: `Table` - a great way to construct complex document structures, e.g. reports. This element covers all cases offered by combination of the `Stack` and the `Row` elements. Additionally, it provides support for more complex layouts and corner cases. Updating to the `Table` element can greatly simplify your code 😁
-- Added a `StopPaging` element - when its child requires more than one page to fully render, only the first page is shown,
+- Added new element `DefaultTextStyle` - it allows set new text style to all its children,
-- Added a 'LineVertical' and a 'LineHorizontal' elements - those will simplify your code a lot, no need to use the `Border` element anymore!
+- Improved the default paging behavior for the `Row` element. In some minor corner cases it might cause infinite layout exceptions and confuse developers.
-- Renaming: the `Stack` element has been renamed to the `Column` element,
+- Fixed default page sizes for: Letter and Legal.
-- Renaming: children of the `Row` elements are not called `items` instead of `columns`, e.g. `ConstantItem`, `RelativeItem`, `AutoItem`,
-- Added support of the `AutoItem` to the `Row` element - those items take as little width as possible,
-- Improved default Fluent configuration behavior for elements: Scale, Padding, Translate,
-- Improved integration support with the HttpContext.Response.Body. This improvement was introduced by schulz3000, thank you!
