How to evolve new Pokemon GO Evee?

To evolve the new Umbreon and Espeon that arrived with the new Pokemon Go update, name them to Tamao and Sakura before you evolve them. 

Unfortunately, the name trick only works once. I have not tried this but I have read that after the first evolution you will need to walk your Evee for 10K, obtain two candy and then evolve your Evee at night for Umbreon or during the day for Expeon. Add a comment if you have success with this method.

Where to get Pokemon GO special items?

The latest Pokemon GO update introduced special items necessary to evolve some new Pokemon. Although they appear to be rare theses special items can be obtained from Pokestops.
