template to create the initial release notes draft.*

*The release notes draft is a temporary file that can be added to by anyone. See

*version* Release Notes Draft
|
|
===============================
|
|
|
|
Bitcoin Core version *version* is now available from:
|
|
|
|
<https://bitcoincore.org/bin/bitcoin-core-*version*/>
|
|
|
|
This release includes new features, various bug fixes and performance
|
|
improvements, as well as updated translations.
|
|
|

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).
|
|
|
|
Upgrading directly from a version of Bitcoin Core that has reached its EOL is
|
|
possible, but might take some time if the datadir needs to be migrated. Old
|
|
wallet versions of Bitcoin Core are generally supported.
|
|
|
|
Compatibility
|
|
==============
|
|
|
|
Bitcoin Core is supported and extensively tested on operating systems using
|
|
the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended
|
|
to use Bitcoin Core on unsupported systems.
|
|
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
|
as 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. Additionally, Bitcoin Core does not yet change appearance when
|
|
macOS "dark mode" is activated.
|
|
|
|
In addition to previously-supported CPU platforms, this release's
|
|
pre-compiled distribution also provides binaries for the RISC-V
|
|
platform.
|
|
|
|
Notable changes
|
|
===============
|
|
|
|
New RPCs
|
|
--------
|
|
|
|
- `getbalances` returns an object with all balances (`mine`,
|
|
`untrusted_pending` and `immature`). Please refer to the RPC help of
|
|
`getbalances` for details. The new RPC is intended to replace
|
|
`getunconfirmedbalance` and the balance fields in `getwalletinfo`, as well as
|
|
`getbalance`. The old calls may be removed in a future version.
|
|
|
|
Updated RPCs
|
|
------------
|
|
|
|
Note: some low-level RPC changes mainly useful for testing are described in the
|
|
Low-level Changes section below.
|
|
|
|
- The `sendmany` RPC had an argument `minconf` that was not well specified and
|
|
would lead to RPC errors even when the wallet's coin selection would succeed.
|
|
The `sendtoaddress` RPC never had this check, so to normalize the behavior,
|
|
`minconf` is now ignored in `sendmany`. If the coin selection does not
|
|
succeed due to missing coins, it will still throw an RPC error. Be reminded
|
|
that coin selection is influenced by the `-spendzeroconfchange`,
|
|
`-limitancestorcount`, `-limitdescendantcount` and `-walletrejectlongchains`
|
|
command line arguments.
|
|
|
|
Deprecated or removed RPCs
|
|
--------------------------
|
|
|
|
- The `totalFee` option of the `bumpfee` RPC has been deprecated and will be
|
|
removed in 0.20. To continue using this option start with
|
|
`-deprecatedrpc=totalFee`. See the `bumpfee` RPC help text for more details.
|
|
|
|
Low-level changes
|
|

|
|

|
Tests
|
|
-----
|
|
|
|
- The regression test chain, that can be enabled by the `-regtest` command line
|
|
flag, now requires transactions to not violate standard policy by default.
|
|
Making the default the same as for mainnet, makes it easier to test mainnet
|
|
behavior on regtest. Be reminded that the testnet still allows non-standard
|
|
txs by default and that the policy can be locally adjusted with the
|
|
`-acceptnonstdtxn` command line flag for both test chains.
|
|
|
|
Configuration
|
|
------------
|
|
|
|
- An error is issued where previously a warning was issued when a setting in
|
|
the config file was specified in the default section, but not overridden for
|
|
the selected network. This change takes only effect if the selected network
|
|
is not mainnet.
|
|
|
|
Network
|
|
-------
|
|
|
|
- When fetching a transaction announced by multiple peers, previous versions of
|
|
Bitcoin Core would sequentially attempt to download the transaction from each
|
|
announcing peer until the transaction is received, in the order that those
|
|
peers' announcements were received. In this release, the download logic has
|
|
changed to randomize the fetch order across peers and to prefer sending
|
|
download requests to outbound peers over inbound peers. This fixes an issue
|
|
where inbound peers can prevent a node from getting a transaction.
|
|
|
|
Wallet
|
|
------
|
|
|
|
- When in pruned mode, a rescan that was triggered by an `importwallet`,
|
|
`importpubkey`, `importaddress`, or `importprivkey` RPC will only fail when
|
|
blocks have been pruned. Previously it would fail when `-prune` has been set.
|
|
This change allows to set `-prune` to a high value (e.g. the disk size) and
|
|
the calls to any of the import RPCs would fail when the first block is
|
|
pruned.
