How to install QT 5.6.1 on Ubuntu 16.04, Linux Mint and Ubuntu Derivative Systems. QT 5.6.1 has been released with the new Qt Creator 4.0.1, included in the Qt 5.6.1 packages.
Qt is a cross-platform application framework that is widely used for developing application software that can be run on various software and hardware platforms with little or no change in the underlying codebase. Qt is used mainly for developing application software with graphical user interfaces (GUIs); however, programs without a GUI can be developed, such as command-line tools and consoles for servers.
Qt is not a programming language by its own. It is a framework written in C++. Qt comes with its own Integrated Development Environment (IDE), named Qt Creator. It runs on Linux, OS X and Windows and offers intelligent code completion, syntax highlighting, an integrated help system, debugger and profiler integration and also integration for all major version control systems.
Qt 5.6.1 has been released today. Since Qt 5.6 is long-term supported for three years, there will still be more patch releases to come. While the patch releases do not bring new features, they do contain security fixes, error corrections and general improvements. The New Qt Creator 4.0.1 is included in the Qt 5.6.1 offline installer packages.
Out of the over 800 improvements, there are many error corrections across all modules of Qt, as well as updates to the documentation and various translations of Qt. Qt 5.6.1 also provides some non-critical security fixes in the Qt framework and in 3rd party libraries.
For those who are using the online installer, Qt 5.6.1 and Qt Creator 4.0.1 can be updated using the maintenance tool.
