I have created a module, and I have to change the permissions implemented (and used) from the module. Should I create a new major version (e.g. passing from 7.x-1 to 7.x-2), or is it fine to create a minor version (e.g. passing from 7.x-1.3 to 7.x-1.4)?
I am talking of a module for which there is already an official release, not of a module that has only a development snapshot.
