- [0a16496](https://togithub.com/ratatui-org/ratatui/commit/0a164965ea2b163433871717cee4fd774a23ee5a) *(uncategorized)* Use `to_string` to serialize Color by [@SleepySwords](https://togithub.com/SleepySwords) in [#934](https://togithub.com/ratatui-org/ratatui/pull/934)
```text
Since deserialize now uses `FromStr` to deserialize color, serializing
`Color` RGB values, as well as index values, would produce an output
that would no longer be able to be deserialized without causing an
error.
```
Color::Rgb will now be serialized as the hex representation of their
value.
For example, with serde_json, `Color::Rgb(255, 0, 255)` would be
serialized as `"#FF00FF"` rather than `{"Rgb": [255, 0, 255]}`.
Color::Indexed will now be serialized as just the string of the index.
For example, with serde_json, `Color::Indexed(10)` would be serialized
as `"10"` rather than `{"Indexed": 10}`.
Other color variants remain the same.
##### Refactor
- [2cfe82a](https://togithub.com/ratatui-org/ratatui/commit/2cfe82a47eb34baa25f474db7be364de7b95374a) *(buffer)* Deprecate assert_buffer_eq! in favor of assert_eq! by [@EdJoPaTo](https://togithub.com/EdJoPaTo) in [#1007](https://togithub.com/ratatui-org/ratatui/pull/1007)
````text
- Simplify `assert_buffer_eq!` logic.
- Deprecate `assert_buffer_eq!`.
- Introduce `TestBackend::assert_buffer_lines`.
Also simplify many tests involving buffer comparisons.
For the deprecation, just use `assert_eq` instead of `assert_buffer_eq`:
```diff
-assert_buffer_eq!(actual, expected);
+assert_eq!(actual, expected);
```
---
I noticed `assert_buffer_eq!` creating no test coverage reports and
looked into this macro. First I simplified it. Then I noticed a bunch of
`assert_eq!(buffer, …)` and other indirect usages of this macro (like
`TestBackend::assert_buffer`).
The good thing here is that it's mainly used in tests so not many
changes to the library code.

```text
We need to make sure to not change existing methods without a notice.
But at the same time this also finds public additions with mistakes
before they are even released which is what I would like to have.
This renames a method and deprecated the old name hinting to a new name.
Should this be mentioned somewhere, so it's added to the release notes?
It's not breaking because the old method is still there.

As per suggestion in

It's good for historical purposes!

Removes the team members that are not able to review PRs recently (with
their approval ofc)

##### Performance
- [366c2a0](https://togithub.com/ratatui-org/ratatui/commit/366c2a0e6d17810b26ba37918e72c2f784176d2c) *(block)* Use Block::bordered by [@EdJoPaTo](https://togithub.com/EdJoPaTo) in [#1041](https://togithub.com/ratatui-org/ratatui/pull/1041)
`Block::bordered()` is shorter than
`Block::new().borders(Borders::ALL)`, requires one less import
(`Borders`) and in case `Block::default()` was used before can even be
`const`.
- [2e71c18](https://togithub.com/ratatui-org/ratatui/commit/2e71c1874e2de6d9f2bd21622246e55484a9fc62) *(buffer)* Simplify Buffer::filled with macro by [@EdJoPaTo](https://togithub.com/EdJoPaTo) in [#1036](https://togithub.com/ratatui-org/ratatui/pull/1036)
```text
The `vec![]` macro is highly optimized by the Rust team and shorter.
Don't do it manually.
This change is mainly cleaner code. The only production code that uses
this is `Terminal::with_options` and `Terminal::insert_before` so it's
not performance relevant on every render.
```
- [81b9633](https://togithub.com/ratatui-org/ratatui/commit/81b96338ea41f9e5fbb0868808a0b450f31eef41) *(calendar)* Use const fn by [@EdJoPaTo](https://togithub.com/EdJoPaTo) in [#1039](https://togithub.com/ratatui-org/ratatui/pull/1039)
```text
Also, do the comparison without `as u8`. Stays the same at runtime and
is cleaner code.

- [c442dfd](https://togithub.com/ratatui-org/ratatui/commit/c442dfd1ad4896e7abeeaac1754b94bae1f8d014) *(canvas)* Change map data to const instead of static by [@EdJoPaTo](https://togithub.com/EdJoPaTo) in [#1037](https://togithub.com/ratatui-org/ratatui/pull/1037)
- [1706b0a](https://togithub.com/ratatui-org/ratatui/commit/1706b0a3e434c51dfed9af88470f47162b615c33) *(crossterm)* Speed up combined fg and bg color changes by up to 20% by [@joshka](https://togithub.com/joshka) in [#1072](https://togithub.com/ratatui-org/ratatui/pull/1072)
- [1a4bb1c](https://togithub.com/ratatui-org/ratatui/commit/1a4bb1cbb8dc98ab3c9ecfce225a591b0f7a36bc) *(layout)* Avoid allocating memory when using split ergonomic utils by [@tranzystorekk](https://togithub.com/tranzystorekk) in [#1105](https://togithub.com/ratatui-org/ratatui/pull/1105)
```text
Don't create intermediate vec in `Layout::areas` and
`Layout::spacers` when there's no need for one.
```
##### Styling
- [aa4260f](https://togithub.com/ratatui-org/ratatui/commit/aa4260f92c869ed77123fab700f9f20b059bbe07) *(uncategorized)* Use std::fmt instead of importing Debug and Display by [@joshka](https://togithub.com/joshka) in [#1087](https://togithub.com/ratatui-org/ratatui/pull/1087)
```text
This is a small universal style change to avoid making this change a
part of other PRs.
[rationale](https://togithub.com/ratatui-org/ratatui/pull/1083#discussion_r1588466060)
```
##### Testing
- [3cc29bd](https://togithub.com/ratatui-org/ratatui/commit/3cc29bdada096283f1fa89d0a610fa6fd5425f9b) *(block)* Use rstest to simplify test cases by [@EdJoPaTo](https://togithub.com/EdJoPaTo) in [#1095](https://togithub.com/ratatui-org/ratatui/pull/1095)
##### Miscellaneous Tasks
- [5fbb77a](https://togithub.com/ratatui-org/ratatui/commit/5fbb77ad205ccff763d71899c2f5a34560d25b92) *(readme)* Use terminal theme for badges by [@TadoTheMiner](https://togithub.com/TadoTheMiner) in [#1026](https://togithub.com/ratatui-org/ratatui/pull/1026)
```text
The badges in the readme were all the default theme. Giving them
prettier colors that match the terminal gif is better. I've used the
colors from the VHS repo.

```text
Add the package categories field in Cargo.toml, with value
`["command-line-interface"]`. This fixes the (currently non-default)
clippy cargo group lint
[`clippy::cargo_common_metadata`](https://rust-lang.github.io/rust-clippy/master/index.html#/cargo_common_metadata).
As per discussion in [Cargo package categories
suggestions](https://togithub.com/ratatui-org/ratatui/discussions/1034),
this lint is not suggested to be run by default in CI, but rather as an
occasional one-off as part of the larger
[`clippy::cargo`](https://doc.rust-lang.org/stable/clippy/lints.html#cargo)
lint group.

```text
Followup to https://github.com/ratatui-org/ratatui/pull/1035 and
https://github.com/ratatui-org/ratatui/discussions/1034
It's reasonable to enable this and deal with breakage by fixing any
specific issues that arise.
