Recently discovered fragments of Dead Sea Scrolls have been found (article here). Last found was over fifty years. Some date back to the third century B.C. to the second century C.E. These were found just 40 miles south of Jerusalem.
Amongst this find was even a single large scroll that included all the minor prophets. The largest scroll was of the Greek Bible called the Septuagint. A fragment was from Jeremiah 8:17.
This is a very significant find because it was spur on more biblical research for many years. However, it will likely not cause any major changes to any of our modern translations. Nevertheless, scholars of textual criticism will still be interested in finding if any textual variants exists.
