+Bitcoin-Qt version 0.8.6 final is now available from:
+
+  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.6/
+
+This is a maintenance release to fix a critical bug; we urge all users to upgrade.
+
+Please report bugs using the issue tracker at github:
+
+  https://github.com/bitcoin/bitcoin/issues
+
+How to Upgrade
+--------------
+
+If you already downloaded 0.8.6rc1 you do not need to re-download. This release is exactly the same.
+
+If you are running an older version, shut it down. Wait
+until it has completely shut down (which might take a few minutes for older
+versions), then run the installer (on Windows) or just copy over
+/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
+
+If you are upgrading from version 0.7.2 or earlier, the first time you
+run 0.8.6 your blockchain files will be re-indexed, which will take
+anywhere from 30 minutes to several hours, depending on the speed of
+your machine.
+
