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
Documentation
- A new document introduces Bitcoin Core's BIP174 Partially-Signed Bitcoin Transactions (PSBT) interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
