What's new?
-----------

* Integrated [Compiler Explorer (https://godbolt.org)](https://godbolt.org)
* CMake debugging and the [Debug Adapter Protocol](https://microsoft.github.io/debug-adapter-protocol/)
* Screen recording

### Compiler Explorer

Use [Compiler Explorer (https://godbolt.org)](https://godbolt.org) in Qt Creator
and enter example code to explore the capabilities of your compilers and
interpreters.

To enable the CompilerExplorer plugin, select
`Help > About Plugins > Utilities > CompilerExplorer`. Then select
`Restart Now` to restart Qt Creator and load the plugin.

Select `File > New File` and select one of the new `Compiler Explorer` templates
to get started.

Alternatively, you can open a new `Compiler Explorer` editor via
`Tools > Compiler Explorer > Open Compiler Explorer`.

Every language, compiler, and library that is supported at <https://godbolt.org>
is also supported in Qt Creator. You can save your Compiler Explorer session as
a `.qtce` file (JSON-based).

([Documentation](https://doc.qt.io/qtcreator/creator-how-to-explore-compiler-code.html))

### CMake Debugging and the Debug Adapter Protocol

Set breakpoints in a CMake file and select
`Debug > Start Debugging > Start CMake Debugging` to start debugging.

([Documentation](https://doc.qt.io/qtcreator/creator-how-to-debug-cmake-files.html))


### Screen Recording

Use `Tools > Record Screen` to record a part of your screen. Requires an
installation of [FFmpeg](https://ffmpeg.org).

To enable the ScreenRecorder plugin, select
`Help > About Plugins > Utilities > ScreenRecorder`. Then select
`Restart Now` to restart Qt Creator and load the plugin.
