The Crossway board of directors and the ESV oversight committee have unanimously decided to make the English Standard Version a permanent text. They announced 52 changes (you can see the announcement here) which are to be the last ones. If I were making a permanent text, I wouldn't add the "(2016)" on the end. But as a Bible reader, I am delighted to hear that there will not a constant string of updates.
UPDATE on September 28, 2016:
As James Snapp noted below, there is now longer a permanent ESV text. It was permanent for a little over a month. Yes, Crossway has reversed the decision to keep the ESV unchanging. You can read a statement by Lane T. Dennis,President and CEO of Crossway about today's reversal here on Crossway's blog.
