If you work translating keywords it will benefit your clients if you are familiar with these changes, especially if your language pair includes any of the languages that are being rolled out early (English, German, Spanish, French, Italian, Dutch, Portuguese, and Russian).
Expect less and less requests asking you to include the +signs and variations of your keyword but be prepared to adapt the way you approach a keyword research project. It will help if you focus on the ad groups carefully and consider longer phrases and the word order for different ways of searching.
It is also likely that you will be asked to work on search query reports often between now and the summer.
