The Third Estimate for Q2 GDP, to one decimal, came in at 3.1% (3.06% to two decimal places), an increase over 1.2% for the Q1 Third Estimate. had a consensus of 3.0%.

Here is the slightly abbreviated opening text from the Bureau of Economic Analysis news release:

Real gross domestic product (GDP) increased at an annual rate of 3.1 percent in the second quarter of 2017 (table 1), according to the "third" estimate released by the Bureau of Economic Analysis. In the first quarter, real GDP increased 1.2 percent.

The GDP estimate released today is based on more complete source data than were available for the "second" estimate issued last month. In the second estimate, the increase in real GDP was 3.0 percent. With this third estimate for the second quarter, private inventory investment increased more than previously estimated, but the general picture of economic growth remains the same. [Full Release]

Here is a look at Quarterly GDP since Q2 1947. Prior to 1947, GDP was an annual calculation. To be more precise, the chart shows is the annualized percentage change from the preceding quarter in Real (inflation-adjusted) Gross Domestic Product. We've also included recessions, which are determined by the National Bureau of Economic Research (NBER). Also illustrated are the 3.22% average (arithmetic mean) and the 10-year moving average, currently at 1.42%.

Quarterly GDP since 1947

Here is a log-scale chart of real GDP with an exponential regression, which helps us understand growth cycles since the 1947 inception of quarterly GDP. The latest number puts us 14.7% below trend.

A particularly telling representation of slowing growth in the US economy is the year-over-year rate of change. The average rate at the start of recessions is 3.35%. Seven of the eleven recessions over this timeframe have begun at a higher level of current real YoY GDP.

Real GDP Year-over-Year

In summary, the Q2 GDP Third Estimate of 3.1% was slightly better than expected, mostly unchanged from the Second Estimate, and a significant improvement from the 1.2% GDP for the previous quarter.
