Google doesn’t often provide advance notice to the world when they are going to make an algorithm update, so it is important we embrace the knowledge and ensure that we are prepared. Prior to this announcement Google began sending notices via Google Webmaster Tools that alerted webmasters as to any mobile usability issues that may be present on their site, and the specific URLs where the issues were found.

Google announced in February there would be an algorithm update to improve mobile search results on April 21st, 2015:

Starting April 21, we will be expanding our use of mobile-friendliness as a ranking signal. This change will affect mobile searches in all languages worldwide and will have a significant impact in our search results. Consequently, users will find it easier to get relevant, high quality search results that are optimized for their devices.To get help with making a mobile-friendly site, check out our guide to mobile-friendly sites.
