Short description of error
The new (and pretty useful, like double clicking) shortcuts for loop select are missing in the latest blender build.
I was using this extensively in the last days, I found it pretty useful, to double click instead of alt + click to select a loop, please bring it back to default again, if not a bug?
Exact steps for others to reproduce the error
Add a cube > Edit Mode > Double left click to select loop
