title: Bitcoin Core version 0.9.3 released | ||
--- | ||
Bitcoin Core version 0.9.3 is now available from: | ||
|
||
<https://bitcoin.org/bin/0.9.3/> | ||
|
||
This is a new minor version release, bringing only bug fixes and updated | ||
translations. Upgrading to this release is recommended. | ||
|
||
Please report bugs using the issue tracker at github: | ||
|
||
<https://github.com/bitcoin/bitcoin/issues> | ||
|
||
Upgrading and downgrading | ||
========================== | ||
|
||
How to Upgrade | ||
-------------- | ||
|
||
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 | ||
0.9.3 your blockchain files will be re-indexed, which will take anywhere from | ||
30 minutes to several hours, depending on the speed of your machine. | ||
|
||
Downgrading warnings | ||
-------------------- | ||
|
||
The 'chainstate' for this release is not always compatible with previous | ||
releases, so if you run 0.9.x and then decide to switch back to a | ||
0.8.x release you might get a blockchain validation error when starting the | ||
old release (due to 'pruned outputs' being omitted from the index of | ||
unspent transaction outputs). | ||
|
||
Running the old release with the -reindex option will rebuild the chainstate | ||
data structures and correct the problem. | ||
|
||
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan | ||
the blockchain for missing spent coins, which will take a long time (tens | ||
of minutes on a typical machine). | ||
|
||
