It looks as though this can be closed if you guys do a release from master? 0.7?

[doomspork]

Thanks @aphillipo! I'm planning to do a release today or tomorrow, busy with work ☹️

[willykaram]

@aphillipo thanks for making that release suggestion.

@doomspork thanks for doing the 0.7.0 release. I just wanted to confirm that the issue is resolved with the 0.7.0 release. I'm writing and updated authentical guide for Phx 1.3, and test this to see that it's working. I think this issue could be closed.

@willykaram thanks! 👍
