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).
|
||
|
|
|
||
|
|
The first time you run version 0.15.0 or higher, your chainstate database will
|
||
|
|
be converted to a new format, which will take anywhere from a few minutes to
|
||
|
|
half an hour, depending on the speed of your machine.
|
||
|
|
|
||
|
|
The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, a
|
||
|
|
downgrade from version 0.15 or upgrade to version 0.15 will cause all fee
|
||
|
|
estimates to be discarded.
|
||
|
|
|
||
|
|
Note that the block database format also changed in version 0.8.0 and there is no
|
||
|
|
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
|
||
|
|
directly from 0.7.x and earlier without redownloading the blockchain is not supported.
|
||
|
|
However, as usual, old wallet versions are still supported.
|
||
|
|
|
||
|
|
Downgrading warning
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
The chainstate database for this release is not compatible with previous
|
||
|
|
releases, so if you run 0.15 and then decide to switch back to any
|
||
|
|
older version, you will need to run the old release with the `-reindex-chainstate`
|
||
|
|
option to rebuild the chainstate data structures in the old format.
|
||
|
|
|
||
|
|
If your node has pruning enabled, this will entail re-downloading and
|
||
|
|
processing the entire blockchain.
|
||
|
|
|
||
|
|
Compatibility
|
||
|
|
==============
|
||
|
|
|
||
|
|
Bitcoin Core is extensively tested on multiple operating systems using
|
||
|
|
the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.
|
||
|
|
|
||
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
||
|
|
frequently tested on them.
|
||
|
|
|
||
|
|
|
||
|
|
