Release notes:

For this release we re-fit our models on historical data from many large new publisher partners. We also improved our methodology by making better use of time-series trends to reflect the steady growth of the app market, especially over the last year and a half. Together, these factors generally caused our estimates for the total market size of each country to change. In most countries, the estimated market size increased; Asian markets were typically the exception. The table below summarizes these changes for the top 10 markets on Google Play.

Percent change in estimated market size (top 10 markets on Google Play, 2016 & Q1 2017):
