Atmosphere complaining about package versions

I’ve started receiving this error when publishing packages:

=> Errors while publishing:                   
                                              
While publishing the package:
error: You must specify a version constraint for package blaze
error: You must specify a version constraint for package templating

I’ve not changed anything (that I can think of), I’ve published the packages in question several times before without needing to explicitly tie blaze/templating (and others) to specific versions.

Is anyone else seeing this?

There have been some changes recently mention in the 1.8.2 PR. If this is a package tied to old version of Meteor then it will require a bump in minimal Meteor version.
But this is still strange indeed.
