Thank you for me to answer, I'm waiting the official release of 1.8 and hope you can shed gradually version 1.8, you by chance manages to come to a launch daily build or night launch as pre alphas versions for testing? Would be compiled versions with bugs to find and report to the development.

how much time to launch the new version of the program? Still a long time? Because I am not able to compile on Windows and not on Linux using the new version of QT Creator with the source code from Github.
