ios-v3.4.0

The release will go through a series of alpha and beta versions until it reaches a stable state and is made generally available. In the alpha phase, we publish a version that have enough new features as to be useful for developers who would like to test and help report issues. In the beta phase, we've locked down most new feature development and are focused on stability issues. In general, after the first alpha, we aim to release a new alpha (or beta) version once per week.
