main features:

• third build with PyQt5, using PyQt5.5.0,
• no more Qt4 packages,
• PyQtGraph and Spyder are 'fresh from Github' versions (to get more Qt5 fixes)
• one know bug: if you install or uninstall only one package at a time with WinPython Control Panel:
  • the package is installed (or uninstalled),
  • then a Window open to show a 'installing'/'uninstalling the package' message
    ==> You have to click the "cancel" button of this useless window to make it go away.

Winpython with Qt5.5 is a new branch, added to the existing ones.
Winpython of next release will include the usual branches under Qt4.11 .
