This release boost vanilla-rtb performance by more then 50% and allows us to run single bidder process with 1700 - 1800 ads/campaigns and bid for every impression within 50K QPS arriving to exchange handler.

Finally we have a mock exchange connecting to our bidder , the exchange can be used to re-play impressions requests and allow us to check how our bidder decreases funds from the campaign budget.

We start releasing vanilla-rtb as container based solution , the docker image should be building automatically
with every tag.
