I don't understand how a breaking change get into a patch release. I see two ways out:

• Revert this commit and release 1.6.2 ASAP. - This option is probably more appropriate.
• Release muzzle plugin 0.8.0 and clarify that 1.6.1 will need muzzle plugin 0.8.0

oh no 😞, thanks for reporting this

unfortunately the 1.6.0 tag depended on a gradle-plugins snapshot, which made releasing 1.6.1 really painful. i think the best is to revert everything in the 1.6.x branch and release 1.6.2 which is essentially the same as 1.6.0, and give up on making a patch release for #4191

oh, and of course we can't just roll back and release 1.6.2 as a copy of 1.6.0, because the problem is that the 1.6.0 tag doesn't build anymore 😭

in the meantime, I've added a warning to the release notes, and posted the warning in the slack channel

[edwardxia]

That is unfortunate, but thanks for getting to it quickly!

1.6.2 is released, please let us know if it resolves the issue for you
