We are happy to announce the release of Qt Creator 5.0 Beta!
As announced in the 4.15 release blog post we are switching to a semantic versioning scheme, so this is the first major version update of Qt Creator in a long time! Don't expect a completely rewritten IDE though - we are still following the incremental development style, and the next feature release of Qt Creator will be 6.0 towards the end of the year.
Qt Creator 5.0 comes with experimental support for Clangd as the backend for the C/C++ code model. It replaces the libclang based code model, building on our support for the Language Server Protocol. As mentioned this is still experimental. Completion doesn't work yet and some of the functionality only works with a development build of Clangd from the "main" branch. If you want to try it, enable "Use clangd" in Tools > Options > C++ > Clangd (or Qt Creator > Preferences > C++ > Clangd on macOS).
Another experimental feature that is shipped with 5.0 is some support for building and running applications in Docker containers. This is very experimental and currently only works on Linux hosts with CMake as the build system for your projects. After you enabled the experimental plugin in Help > About Plugins (or Qt Creator > About Plugins on macOS), you can create a Docker device in the Device settings and set that as a "Build device" and "Device" in a Kit.
