- The `TextInput` widget, an input field allowing interactive text input.
- The `Donut` widget can now display an optional text label under the donut.

Changed

- Widgets now get information whether their container is focused when Draw is
  executed.
- The SegmentDisplay widget now has a method that returns the observed character
  capacity the last time Draw was called.
- The grid.Builder API now allows users to specify options for intermediate
  containers, i.e. containers that don't have widgets, but represent rows and
  columns.
- Line chart widget now allows `math.NaN` values to represent "no value" (values
  that will not be rendered) in the values slice.

Breaking API changes

- The widgetapi.Widget.Draw method now accepts a second argument which provides
  widgets with additional metadata. This affects all implemented widgets.
- Termdash now requires at least Go version 1.10, which allows us to utilize
  `math.Round` instead of our own implementation and `strings.Builder` instead
  of `bytes.Buffer`.
- Terminal shortcuts like `Ctrl-A` no longer come as two separate events,
  Termdash now mirrors termbox-go and sends these as one event.

v0.8.0

v0.8.0 - 30-Mar-2019

Added

- New API for building layouts, a grid.Builder. Allows defining the layout
  iteratively as repetitive Elements, Rows and Columns.
- Containers now support margin around them and padding of their content.
- Container now supports dynamic layout changes via the new Update method.

Changed

- The Text widget now supports content wrapping on word boundaries.
- The BarChart and SparkLine widgets now have a method that returns the
  observed value capacity the last time Draw was called.
- Moving widgetapi out of the internal directory to allow external users to
  develop their own widgets.
- Event delivery to widgets now has a stable defined order and happens when the
  container is unlocked so that widgets can trigger dynamic layout changes.

Fixed

- The termdash_test now correctly waits until all subscribers processed events,
  not just received them.
- Container focus tracker now correctly tracks focus changes in enlarged areas,
  i.e. when the terminal size increased.
- The BarChart, LineChart and SegmentDisplay widgets now protect against
  external mutation of the values passed into them by copying the data they
  receive.

v0.7.0

v0.7.0 - 24-Feb-2019

Added

- New widgets

-- The Button widget.

- Improvements to documentation

-- Clearly marked the public API surface by moving private packages into
   internal directory.
-- Started a GitHub wiki for Termdash.

- Improvements to the LineChart widget

-- The LineChart widget can display X axis labels in vertical orientation.
-- The LineChart widget allows the user to specify a custom scale for the Y
   axis.
-- The LineChart widget now has an option that disables scaling of the X axis.
   Useful for applications that want to continuously feed data and make them
   "roll" through the linechart.
-- The LineChart widget now has a method that returns the observed capacity of
   the LineChart the last time Draw was called.
-- The LineChart widget now supports zoom of the content triggered by mouse
   events.

- Improvements to the Text widget

-- The Text widget now has a Write option that atomically replaces the entire
   text content.

- Improvements to the infrastructure

-- A function that draws text vertically.
-- A non-blocking event distribution system that can throttle repetitive events.
-- Generalized mouse button FSM for use in widgets that need to track mouse
   button clicks.

Changed

- Termbox is now initialized in 256 color mode by default.
- The infrastructure now uses the non-blocking event distribution system to
  distribute events to subscribers. Each widget is now an individual
  subscriber.
- The infrastructure now throttles event driven screen redraw rather than
  redrawing for each input event.
- Widgets can now specify the scope at which they want to receive keyboard and
  mouse events.

- Breaking API changes

-- High impact

--- The constructors of all the widgets now also return an error so that they
    can validate the options. This is a breaking change for the following
    widgets: BarChart, Gauge, LineChart, SparkLine, Text. The callers will have
    to handle the returned error.

-- Low impact

--- The container package no longer exports separate methods to receive Keyboard
    and Mouse events which were replaced by a Subscribe method for the event
    distribution system. This shouldn't affect users as the removed methods
    aren't needed by container users.
--- The widgetapi.Options struct now uses an enum instead of a boolean when
    widget specifies if it wants keyboard or mouse events. This only impacts
    development of new widgets.

Fixed

- The LineChart widget now correctly determines the Y axis scale when multiple
  series are provided.
- Lint issues in the codebase, and updated Travis configuration so that golint
  is executed on every run.
- Termdash now correctly starts in locales like zh_CN.UTF-8 where some of the
  characters it uses internally can have ambiguous width.
