fix: add unstable-backend-writer feature (#1352)

+
+### `Backend::size` returns `Size` instead of `Rect` ([#1254])
+
+[#1254]: https://github.com/ratatui/ratatui/pull/1254
+
+The `Backend::size` method returns a `Size` instead of a `Rect`.
+There is no need for the position here as it was always 0,0.
+
+### `Backend` trait migrates to `get/set_cursor_position` ([#1284])
+
+[#1284]: https://github.com/ratatui/ratatui/pull/1284
+
+If you just use the types implementing the `Backend` trait, you will see deprecation hints but
+nothing is a breaking change for you.
+
+If you implement the Backend trait yourself, you need to update the implementation and add the
+`get/set_cursor_position` method. You can remove the `get/set_cursor` methods as they are deprecated
+and a default implementation for them exists.
+
+### Ratatui now requires Crossterm 0.28.0 ([#1278])
+
+[#1278]: https://github.com/ratatui/ratatui/pull/1278
+
+Crossterm is updated to version 0.28.0, which is a semver incompatible version with the previous
+version (0.27.0). Ratatui re-exports the version of crossterm that it is compatible with under
+`ratatui::crossterm`, which can be used to avoid incompatible versions in your dependency list.
+
+### `Axis::labels()` now accepts `IntoIterator<Into<Line>>` ([#1273] and [#1283])
+
+[#1273]: https://github.com/ratatui/ratatui/pull/1173
+[#1283]: https://github.com/ratatui/ratatui/pull/1283
+
+Previously Axis::labels accepted `Vec<Span>`. Any code that uses conversion methods that infer the
+type will need to be rewritten as the compiler cannot infer the correct type.
+
+```diff
+- Axis::default().labels(vec!["a".into(), "b".into()])
++ Axis::default().labels(["a", "b"])
+```
+
+### `Layout::init_cache` no longer returns bool and takes a `NonZeroUsize` instead of `usize` ([#1245])
+
+[#1245]: https://github.com/ratatui/ratatui/pull/1245
+
+```diff
+- let is_initialized = Layout::init_cache(100);
++ Layout::init_cache(NonZeroUsize::new(100).unwrap());
+```
+
+### `ratatui::terminal` module is now private ([#1160])
+
+[#1160]: https://github.com/ratatui/ratatui/pull/1160
+
+The `terminal` module is now private and can not be used directly. The types under this module are
+exported from the root of the crate. This reduces clashes with other modules in the backends that
+are also named terminal, and confusion about module exports for newer Rust users.
+
+```diff
+- use ratatui::terminal::{CompletedFrame, Frame, Terminal, TerminalOptions, ViewPort};
++ use ratatui::{CompletedFrame, Frame, Terminal, TerminalOptions, ViewPort};
+```
+
+### `ToText` no longer has a lifetime ([#1234])
+
+[#1234]: https://github.com/ratatui/ratatui/pull/1234
+
+This change simplifies the trait and makes it easier to implement.
+
+### `Frame::size` is deprecated and renamed to `Frame::area`
+
+[#1293]: https://github.com/ratatui/ratatui/pull/1293
+
+`Frame::size` is renamed to `Frame::area` as it's the more correct name.
+
+## [v0.27.0](https://github.com/ratatui/ratatui/releases/tag/v0.27.0)
+
+### List no clamps the selected index to list ([#1159])
+
+[#1149]: https://github.com/ratatui/ratatui/pull/1149
+
+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`.
+
+Previously selecting an index past the end of the list would show treat the list as having a
+selection which was not visible. Now the last item in the list will be selected instead.
+
+### Prelude items added / removed ([#1149])
+
+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.
+  This may cause conflicts for types defined elsewhere with a similar
+  name.
+
+To update your app:
+
+```diff
+// if your app uses Styled::style() or Styled::set_style():
+-use ratatui::prelude::*;
++use ratatui::{prelude::*, style::Styled};
+
+// if your app uses symbols::Marker:
+-use ratatui::prelude::*;

+// if your app uses terminal::{CompletedFrame, TerminalOptions, Viewport}

+- use some_crate::{Position, Size};
+- let size: Size = ...;
+- let position: Position = ...;
++ let size: some_crate::Size = ...;

+
+### Termion is updated to 4.0 [#1106]
+
+Changelog: <https://gitlab.redox-os.org/redox-os/termion/-/blob/master/CHANGELOG.md>
+
+A change is only necessary if you were matching on all variants of the `MouseEvent` enum without a
+wildcard. In this case, you need to either handle the two new variants, `MouseLeft` and
+`MouseRight`, or add a wildcard.

+
+```diff

+
+### `Stylize::bg()` now accepts `Into<Color>` ([#1103])
+
+[#1103]: https://github.com/ratatui/ratatui/pull/1103
+
+Previously, `Stylize::bg()` accepted `Color` but now accepts `Into<Color>`. This allows more
+flexible types from calling scopes, though it can break some type inference in the calling scope.
+
+### Remove deprecated `List::start_corner` and `layout::Corner` ([#759])
+
+[#759]: https://github.com/ratatui/ratatui/pull/759
+
+`List::start_corner` was deprecated in v0.25. Use `List::direction` and `ListDirection` instead.
+
+```diff
+- list.start_corner(Corner::TopLeft);
+- list.start_corner(Corner::TopRight);

+
+```diff
+- list.start_corner(Corner::BottomLeft);
+// becomes
++ list.direction(ListDirection::BottomToTop);

+
+`layout::Corner` was removed entirely.
+
+### `LineGauge::gauge_style` is deprecated ([#565])
+
+[#565]: https://github.com/ratatui/ratatui/pull/1148
+
+`LineGauge::gauge_style` is deprecated and replaced with `LineGauge::filled_style` and `LineGauge::unfilled_style`:

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+https://forum.ratatui.rs/ or https://discord.gg/pMCEU9hNEj.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.

+## Design choices
+
+The examples contain some opinionated choices in order to make it easier for newer rustaceans to
+easily be productive in creating applications:
+
+- Each example has an App struct, with methods that implement a main loop, handle events and drawing
+  the UI.
+- We use color_eyre for handling errors and panics. See [How to use color-eyre with Ratatui] on the
+  website for more information about this.
+- Common code is not extracted into a separate file. This makes each example self-contained and easy
+  to read as a whole.
+
+Not every example has been updated with all these points in mind yet, however over time they will
+be. None of the above choices are strictly necessary for Ratatui apps, but these choices make
+examples easier to run, maintain and explain. These choices are designed to help newer users fall
+into the pit of success when incorporating example code into their own apps. We may also eventually
+move some of these design choices into the core of Ratatui to simplify apps.

+//! # [Ratatui] Async example
+//!
+//! This example demonstrates how to use Ratatui with widgets that fetch data asynchronously. It
+//! uses the `octocrab` crate to fetch a list of pull requests from the GitHub API. You will need an
+//! environment variable named `GITHUB_TOKEN` with a valid GitHub personal access token. The token
+//! does not need any special permissions.
+//!
+//! <https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#creating-a-fine-grained-personal-access-token>
+//! <https://github.com/settings/tokens/new> to create a new token (select classic, and no scopes)
+//!
+//! This example does not cover message passing between threads, it only demonstrates how to manage
+//! shared state between the main thread and a background task, which acts mostly as a one-shot
+//! fetcher. For more complex scenarios, you may need to use channels or other synchronization
+//! primitives.
+//!
+//! A simple app might have multiple widgets that fetch data from different sources, and each widget
+//! would have its own background task to fetch the data. The main thread would then render the
+//! widgets with the latest data.
+//!
+//! The latest version of this example is available in the [examples] folder in the repository.
+//!
+//! Please note that the examples are designed to be run against the `main` branch of the Github
+//! repository. This means that you may not be able to compile with the latest release version on
+//! crates.io, or the one that you have installed locally.
+//!
+//! See the [examples readme] for more information on finding examples that match the version of the
+//! library you are using.

-//! ![Hello World example](https://vhs.charm.sh/vhs-2UxNc2SJgiNqHoowbsXAMW.gif)
-//!
-//! # Installation
-//!
-//! ```shell
-//! cargo add ratatui tui-big-text
-//! ```
-//!
-//! # Usage
-//!
-//! Create a [`BigText`] widget using `BigTextBuilder` and pass it to [`Frame::render_widget`] to
-//! render be rendered. The builder allows you to customize the [`Style`] of the widget and the
-//! [`PixelSize`] of the glyphs. The [`PixelSize`] can be used to control how many character cells
-//! are used to represent a single pixel of the 8x8 font.
-//!
-//! # Example
-//!
-//! ```rust
-//! use anyhow::Result;
-//! use ratatui::prelude::*;
-//! use tui_big_text::{BigTextBuilder, PixelSize};
-//!
-//! fn render(frame: &mut Frame) -> Result<()> {

-//! When exiting normally or when handling `Result::Err`, we can reset the
-//! terminal manually at the end of `main` just before we print the error.
+//! Prior to Ratatui 0.28.1, a panic hook had to be manually set up to ensure that the terminal was
+//! reset when a panic occurred. This was necessary because a panic would interrupt the normal
+//! control flow and leave the terminal in a distorted state.
 //!
-//! Because a panic interrupts the normal control flow, manually resetting the
-//! terminal at the end of `main` won't do us any good. Instead, we need to
-//! make sure to set up a panic hook that first resets the terminal before
-//! handling the panic. This both reuses the standard panic hook to ensure a
-//! consistent panic handling UX and properly resets the terminal to not
-//! distort the output.
+//! Starting with Ratatui 0.28.1, the panic hook is automatically set up by the new `ratatui::init`
+//! function, so you no longer need to manually set up the panic hook. This example now demonstrates
+//! how the panic hook acts when it is enabled by default.
 //!
-//! That's why this example is set up to show both situations, with and without
-//! the chained panic hook, to see the difference.
