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 your node has a txindex, the txindex db will be migrated the first time you run 0.17.0 or newer, which may take up to a few hours. Your node will not be functional until this migration completes.

The first time you run version 0.15.0 or newer, 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.

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 10.10+, and Windows 7 and newer (Windows XP is not supported).

Bitcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

From 0.17.0 onwards macOS <10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10.

Notable changes

listtransactions label support

The listtransactions RPC account parameter which was deprecated in 0.17.0 and renamed to dummy has been un-deprecated and renamed again to label.

When bitcoin is configured with the -deprecatedrpc=accounts setting, specifying a label/account/dummy argument will return both outgoing and incoming transactions. Without the -deprecatedrpc=accounts setting, it will only return incoming transactions (because it used to be possible to create transactions spending from specific accounts, but this is no longer possible with labels).

When -deprecatedrpc=accounts is set, it’s possible to pass the empty string “” to list transactions that don’t have any label. Without -deprecatedrpc=accounts, passing the empty string is an error because returning only non-labeled transactions is not generally useful behavior and can cause confusion.
