Qt Creator (64-bit)

What's new in this version:

Generic Programming Language Support:
- In Qt Creator 4.8 we introduced experimental support for the language server protocol. This enables editing support for a wide range of programming languages through a common protocol. In 4.9 we add support for the document outline, find usages, and also for code actions, which allow the language server to suggest fixes or refactoring actions at a specified place in the code. If the language server of your favorite programming language supports these features, they are now available in Qt Creator as well. Enable the LanguageClient plugin in Help > About Plugins (Qt Creator > About Plugins on macOS) and configure your server in Tools > Options > Language Client to check it out

C++ Support:
- The UI for diagnostics from the Clang analyzer tools got many improvements. They are grouped by file now. Diagnostics from the project’s headers files are now also included
- Fix-its show details on what they do when applied. We also added a guard against applying Fix-its to files that have changed in the meantime. In the Clazy configuration you can enable or disable individual checks

QML Support:
- We updated our QML parser to Qt 5.12, adding support for ECMAScript 7

Profiling:
- Perf is a powerful performance profiling tool for software running on a Linux system. Profile your application via perf with Analyze > Performance Analyzer, after enabling the plugin in Help > About Plugins. The integration in Qt Creator is available for applications running on a local Linux system, and also for applications running on a remote Linux system from a Linux or Windows host

Generic Projects:
- Similar to our support for deploying files to a remote system for CMake-based projects, you can now add a QtCreatorDeployment.txt file to your generic project, to specify the necessary information about where to deploy which files

Other Improvements:
- For Windows, we added support for MSVC 2019. On macOS we added a Touch Bar if you run Qt Creator on a MacBook.
