# Changelog

## To be released

## v0.3.1-beta.1 - 2018-09-08

### Changed

* Replace `Item` by a generic and flexible `Text` that can be used in both
`Paragraph` and `List` widgets.
* Remove unecessary borrows on `Style`.

## v0.3.0-beta.0 - 2018-09-04

### Added

* Add a basic `Crossterm` backend

### Changed

* Remove `Group` and introduce `Layout` in its place
  - `Terminal` is no longer required to compute a layout
  - `Size` has been renamed `Constraint`
* Widgets are rendered on a `Frame` instead of a `Terminal` in order to
avoid mixing `draw` and `render` calls
* `draw` on `Terminal` expects a closure where the UI is built by rendering
widgets on the given `Frame`
* Update `Widget` trait
  - `draw` takes area by value
  - `render` takes a `Frame` instead of a `Terminal`
* All widgets use the consumable builder pattern
* `SelectableList` can have no selected item and the highlight symbol is hidden
in this case
* Remove markup langage inside `Paragraph`. `Paragraph` now expects an iterator
of `Text` items

### Added

* Add `start_corner` option for `List`
* Add more text aligment options for `Paragraph`
