Known Issues - Qt 5.1.0

All platforms

• Check that your system meets Qt's requirements.
• All open issues can be found from Jira: https://bugreports.qt.io

• At the moment there is only part of mirrors up to date. That's why downloading might take more time than usual. This will be better when content is up to date in each mirror

• Online installer needs to be updated
  • Even if you have used the Qt5.1 RC1 online installer previously, please download & use the new version of online installer packages. Starting from 5.1.0 final the updater/maintenance tool works normally, i.e. you will get 5.1.1 etc.

• Installation over the existing installation not supported
  • QTIFW-278: SDK 5.1.0 rc1 : installation over existing installation fails

• QTBUG-28357:QML apps based on QQuickViewer are not runnable using static build of Qt 5 due to "qtquick2plugin" issue

• QTBUG-31565: When deploying a Qt Quick Controls based application, it is currently necessary to install all the relevant qml and js files. This can be problematic on some platforms, and we plan to address this in the future.
