The following issues should be reviewed and tested in this version:

• Back layer is prioritized when measuring overlapping wires Back layer is prioritized when measuring overlapping wires circuit-construction-kit-common#143
• Vertices don't connect in build screen Vertices don't connect in build screen circuit-construction-kit-common#141
• Vertex pushing Vertex pushing circuit-construction-kit-common#128

This is also the first version with electrons in the black box study version and it would be good for that feature to be tested thoroughly.

Testing on several platforms would be great, but it does not need to be exhaustive for the study (so a small handful of platforms would be fine).

@ariel-phet can you please prioritize and reassign?

[samreid]

For the 3 issues mentioned above, I have assigned them to the original reporters and removed the "hold" label, but it remains for @ariel-phet to indicate priority.

@phet-steele and QA team please make current top testing priority, however, this priority will be immediately superseded #634 once that task goes live

@samreid we're done! 👍

Thanks @phet-steele @alynne-phet and @brroberts1231! Everything is tracked elsewhere, closing.
