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.
