opendrive 1.5 version support ?

[lancelot-Yagami]

I can open xodr files from opendrive version 1.5 with odrviewer, but libOpenDRIVE only supports version 1.4?

I loaded a version 1.7 XODR file. The road geometry can be displayed properly in ODRViewer, but the road connections are missing, possibly because the field names in the junction section are different. So I think ODRViewer can correctly display road geometry from different XODR versions, but due to version differences, the road connections may be lost.
