Please add tag, so podspec can be updated

[iljaiwas]

Please add a tag to the most recent commit, so I can update the CocoaPod podspec file to point to it.

Seems there is a bug in the CocoaPods trunk push command, that doesn't let me update the pod, even though I use the --allow-warnings option.

ilja$ pod trunk push --allow-warnings
