* Bazel: general improvements.

Improve the Bazel build. Attempt to fix previous errors recorded while
trying to publish ftxui in the Bazel Central Registry:
- https://github.com/bazelbuild/bazel-central-registry/pull/4485
- https://buildkite.com/bazel/bcr-presubmit/builds/13601#01968b61-f5b2-4d16-94d0-c87a03a1a23b

Test against "recent" platforms
-------------------------------

Previously, I got the error:
```
gcc: error: unrecognized command line option '-std-c++20'; did you mean '-std-c++2a'?
```
This was due to using old distribution like ubuntu 2004. Test against
newer platforms only to avoid GCC version<-9.x.y

Downgrade gtest version.
------------------------

I suspect this caused the Bazel Central Registry error:
```
file:///workdir/modules/googletest/1.15.2/MODULE.bazel:68:20: name 'use_repo_rule' is not defined
```
Specifying using bazelmod fixes the issue. Thanks @robinlinden

Tag gtest as dev_dependency
---------------------------

Presumably, this should avoid dependants to fetch it?

Enable --features-layering_check
--------------------------------

Aka clang `-Wprivate-header`. Fix the encountered errors.

Use clang in the CI
-------------------

The CI was defining clang/gcc in the matrix, but was not using it. Fix
the bug.

 Changelog
 =========
 
-current (development) 
+Development
----------------------
+-----------
+
+### Build
+- Feature: Support C++20 modules. 
+  This requires:
+  - Using the Ninja or MSVC generator
+  - A recent Clang/GCC/MSVC compiler.
+  - Cmake 3.28 or higher.
+  Usage:
+  ```cpp
+  import ftxui;
+  import ftxui.component;
+  import ftxui.dom;
+  import ftxui.screen;
+  ```
+  Thanks @mikomikotaishi for PR #1015.
+
+
+Future release
+=======
+6.1.9 (2025-05-07
+
+### Build
+If all goes well (pending), ftxui should appear in the Bazel central repository.
+It can be imported into your project using the following lines:
+
+**MODULE.bazel**
+```bazel
+bazel_dep(name = "ftxui", version = "6.1.9")
+```
+
+Thanks @robinlinden and @kcc for the reviews.
+
+### dom
+- Bugfix: Restore the `dbox` behavior from ftxui 5.0.0. To apply bgcolor
+  blending between the two layers, a new `dboxBlend` will be added.
+
+6.1.8 (2025-05-01)
+------------------
+
+### Build
+- Feature: Support `bazel` build system. See #1032.
+  Proposed by Kostya Serebryany @kcc
+
+  **BUILD.bazel**
+  ```bazel
+  deps = [
+    // Depend on the whole library:

+    "@ftxui//:component",
+    "@ftxui//:dom",
+    "@ftxui//:screen",
+  ]
+  ```
+
+### Component
+- Bugfix: Fix a crash with ResizeableSplit. See #1023.
+  - Clamp screen size to terminal size.
+  - Disallow `ResizeableSplit` with negative size.
+
+### Dom
+- Bugfix: Disallow specifying a negative size constraint. See #1023.
+
+
+6.0.2 (2025-03-30)
+-----
+
+### Component
+- BugFix: Fix major crash on Windows affecting all components. See #1020
+- BugFix: Fix focusRelative.
+
+6.0.1 (2025-03-28)
+-----
+
+Same as v6.0.0.
+
+Due to a problem tag v6.0.0 was replaced. This isn't a good practice and affect
+developers that started using it in the short timeframe. Submitting a new
+release with the same content is the best way to fix this.
+
+See #1017 and #1019.

+- Bugfix: Fix crash in `LinearGradient` due to float precision and an off-by-one

 ### Dom
+- Feature: Add `italic` decorator. For instance:

+  ```
+  ```cpp
+  auto italic_text = italic(text("Italic text"));
+  ```

   reflecting the current scroll position. Proposed by @ibrahimnasson in
   [issue 752](https://github.com/ArthurSonzogni/FTXUI/issues/752)
 - Feature: Add `extend_beyond_screen` option to `Dimension::Fit(..)`, allowing
   the element to be larger than the screen. Proposed by @LordWhiro. See #572 and
   #949.

+  - See `selectionStyleReset` decorator.
+- Breaking change: Change how "focus"/"select" are handled. This fixes the

+- Breaking change: `Component::OnRender()` becomes the method to override to
+  render a component. This replaces `Component::Render()` that is still in use
+  to call the rendering method on the children. This change allows to fix a
+  couple of issues around focus handling.
 
 ### Screen
 - Feature: Add `Box::IsEmpty()`.

+
 
 If you choose to build and link FTXUI yourself, `ftxui-component` must be first in the linking order relative to the other FTXUI libraries, i.e.
 ```bash
 g++ . . . -lftxui-component -lftxui-dom -lftxui-screen . . .
 ```
 
-
+To build FTXUI with modules, ensure that you are using a generator like Ninja or Visual Studio that supports modules, and pass the flag `FTXUI_BUILD_MODULES`.
