Release of the Qt 5.5 framework
Yesterday, after six months of development, version 5.5 of the Qt cross-platform framework was released.
Qt allows you to develop applications using C ++ and the declarative programming language QML, supports all major desktop and mobile platforms, as well as some embedded and has open source code. There is a commercial version of Qt containing additional proprietary modules.
Compared with the previous version, about 5.5 were made about 1500 fixes and added new functionality. For details, I ask under the cat.

In addition to the open source version, two commercial versions will now be available:
Outdated Qt WebKit, Qt Quick 1 and Qt Script. All of them are available in Qt 5.5, but it is strongly recommended to switch to newer alternatives: Qt WebView and QML.

- Added a new framework for video filters, allowing for real-time video processing. For example, you can perform OpenCL / CUDA video processing and use OpenCV for pattern recognition. A demo that uses OpenCV to recognize road signs in a video:
. - The Chromium engine in Qt WebEngine has been updated to version 40. Added APIs to manage file downloads, cache, cookies, and settings. Added support for Qt WebChannel.
