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.

||
|
|
- There have been frequent reports of users running out of virtual memory on 32-bit systems
