##### Features
- [eef1afe](https://togithub.com/ratatui-org/ratatui/commit/eef1afe9155089dca489a9159c368a5ac07e7585) *(linegauge)* Allow LineGauge background styles by [@nowNick](https://togithub.com/nowNick) in [#565](https://togithub.com/ratatui-org/ratatui/pull/565)
```text
This PR deprecates `gauge_style` in favor of `filled_style` and
`unfilled_style` which can have it's foreground and background styled.
`cargo run --example=line_gauge --features=crossterm`

Implements:[#424](https://togithub.com/ratatui-org/ratatui/issues/424)
- [1365620](https://togithub.com/ratatui-org/ratatui/commit/13656206064b53c7f86f179b570c7769399212a3) *(borders)* Add FULL and EMPTY border sets by [@joshka](https://togithub.com/joshka) in [#1182](https://togithub.com/ratatui-org/ratatui/pull/1182)
`border::FULL` uses a full block symbol, while `border::EMPTY` uses an
empty space. This is useful for when you need to allocate space for the
border and apply the border style to a block without actually drawing a
border. This makes it possible to style the entire title area or a block
rather than just the title content.
```rust
use ratatui::{symbols::border, widgets::Block};
let block = Block::bordered().title("Title").border_set(border::FULL);
let block = Block::bordered().title("Title").border_set(border::EMPTY);

Add an example that demonstrates logging to a file for:

- [46977d8](https://togithub.com/ratatui-org/ratatui/commit/46977d88519d28ccac1c94e171af0c9cca071dbc) *(list)* Add list navigation methods (first, last, previous, next) by [@joshka](https://togithub.com/joshka) in [#1159](https://togithub.com/ratatui-org/ratatui/pull/1159) \[**breaking**]
```text
Also cleans up the list example significantly (see also
)
```
Fixes:[#1159](https://togithub.com/ratatui-org/ratatui/pull/1159)
BREAKING CHANGE:The `List` widget now clamps the selected index to the
bounds of the list when navigating with `first`, `last`, `previous`, and
`next`, as well as when setting the index directly with `select`.
- [10d7788](https://togithub.com/ratatui-org/ratatui/commit/10d778866edea55207ff3f03d063c9fec619b9c9) *(style)* Add conversions from the palette crate colors by [@joshka](https://togithub.com/joshka) in [#1172](https://togithub.com/ratatui-org/ratatui/pull/1172)
````text
This is behind the "palette" feature flag.
```rust
use palette::{LinSrgb, Srgb};
use ratatui::style::Color;
let color = Color::from(Srgb::new(1.0f32, 0.0, 0.0));
let color = Color::from(LinSrgb::new(1.0f32, 0.0, 0.0));

let text = 666.to_text();

- [74a32af](https://togithub.com/ratatui-org/ratatui/commit/74a32afbaef8851f9462b27094d88d518e56addf) *(uncategorized)* Re-export backends from the ratatui crate by [@joshka](https://togithub.com/joshka) in [#1151](https://togithub.com/ratatui-org/ratatui/pull/1151)
```text
`crossterm`, `termion`, and `termwiz` can now be accessed as
`ratatui::{crossterm, termion, termwiz}` respectively. This makes it
possible to just add the Ratatui crate as a dependency and use the
backend of choice without having to add the backend crates as
dependencies.
To update existing code, replace all instances of `crossterm::` with
`ratatui::crossterm::`, `termion::` with `ratatui::termion::`, and
`termwiz::` with `ratatui::termwiz::`.

```text
It is sometimes useful to obtain access to the writer if we want to see
what has been written so far. For example, when using &mut [u8] as a
writer.

```text
unicode-width 0.1.13 changed the width of \u{1} from 0 to 1.

`layout::Corner` is removed entirely.

Prelude glob imports not in examples are not covered by this PR.

Simplify the List example by removing lifetimes not strictly necessary

```text
his PR removes the items from the prelude that don't form a coherent
common vocabulary and adds the missing items that do.
Based on a comment at
```
BREAKING CHANGE:The following items have been removed from the prelude:
- `style::Styled` - this trait is useful for widgets that want to
support the Stylize trait, but it adds complexity as widgets have two
`style` methods and a `set_style` method.
- `symbols::Marker` - this item is used by code that needs to draw to
the `Canvas` widget, but it's not a common item that would be used by
most users of the library.
- `terminal::{CompletedFrame, TerminalOptions, Viewport}` - these items
are rarely used by code that needs to interact with the terminal, and
they're generally only ever used once in any app.
The following items have been added to the prelude:
- `layout::{Position, Size}` - these items are used by code that needs
to interact with the layout system. These are newer items that were
added in the last few releases, which should be used more liberally.

```text
Codegen units are optimized on their own. Per default bench / release
have 16 codegen units. What ends up in a codeget unit is rather random
and can influence a benchmark result as a code change can move stuff
into a different codegen unit → prevent / allow LLVM optimizations
unrelated to the actual change.
