I believe this whole confusion was because of one simple oversight on our part.
When we pushed a new GitHub release for our firmware, we forgot to do the same for the Ringo library.
The Ringo library release 1.0.0 is the latest release, but it’s not the library version that we used to compile the 1.0.1 firmware binary.
To solve this you can download the current master branch of the Ringo library, or download it zipped from the new 1.0.1 release that got pushed a few moments earlier from writing this.
We will keep in mind all your constructive feedback in our future version management : )
