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.
