Revision control
++ Qt 5.6.3 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with previous Qt 5.6.x releases.
++
++ For more details, refer to the online documentation included in this
++ distribution. The documentation is also available online:
++
++
++ The Qt version 5.6 series is binary compatible with the 5.5.x series.
++ Applications compiled for 5.5 will continue to run with 5.6.
