AHEasing inconsistency of release tag version on github and cocoapods version

My app's dependent library is using AHEasing. But current versions of AHEasing between github and cocoapods are not same so I can't do CI with travis now.

https://github.com/warrenm/AHEasing/releases : 1.3.1
https://cocoapods.org/pods/AHEasing : 1.2

I tried to run pod trunk push AHEasing.podspec.json with json below, but I couldn't successfully completed because of I'm not a maintainer or contributer. 😓
