Highlights of the Qt Creator 5.0 release include experimental Clangd support as the backend for the C/C++ code model, which means that it’s not enabled by default so you have to activate it from Tools > Options > C++ > Clangd > Use clangd. It also features experimental support for building and running apps in Docker containers, which only works on Linux systems that use CMake as the build system for projects.
Also new is a highlighting option for function parameters, template parameters for symbols in the Locator, support for snippets, find support to Issues pane, a new “Show Source and Header Groups” option in the project tree, a new “Force logging to console” option for debugging, line ending and indentation in the file properties information, as well as menu item and shortcut for editing bookmark comments.
