Bitcoin Knots version *0.15.0.knots20170914* is now available from:

  <https://bitcoinknots.org/files/0.15.x/0.15.0.knots20170914/>

This is a new major version release, including new features, various bugfix=
es
and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

  <https://github.com/bitcoinknots/bitcoin/issues>

How to Upgrade
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

If you are running an older version, shut it down. Wait until it has comple=
tely
shut down (which might take a few minutes for older versions), then run the=
=20
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, your chainstate database will be con=
verted 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 0.15.0 or upgrade to version 0.15.0 will cause all f=
ee
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
=2D------------------

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-chai=
nstate`
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Bitcoin Knots is supported on multiple operating systems using the Linux ke=
rnel,
macOS 10.8+, and Windows Vista and later. Windows XP is not supported.

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

Notable changes
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Performance Improvements
=2D-----------------------

Version 0.15 contains a number of significant performance improvements, whi=
ch make
Initial Block Download, startup, transaction and block validation much fast=
er:

=2D The chainstate database (which is used for tracking UTXOs) has been cha=
nged
  from a per-transaction model to a per-output model (See [PR 10195](https:=
//github.com/bitcoin/bitcoin/pull/10195)). Advantages of this=20
model
  are that it:
    - avoids the CPU overhead of deserializing and serializing the unused o=
utputs;
    - has more predictable memory usage;
    - uses simpler code;
    - is adaptable to various future cache flushing strategies.

  As a result, validating the blockchain during Initial Block Download (IBD=
) and reindex
  is ~30-40% faster, uses 10-20% less memory, and flushes to disk far less =
frequently.
  The only downside is that the on-disk database is 15% larger. During the =
conversion from the previous format
  a few extra gigabytes may be used.
=2D Earlier versions experienced a spike in memory usage while flushing UTX=
O updates to disk.
  As a result, only half of the available memory was actually used as cache=
, and the other half was
  reserved to accommodate flushing. This is no longer the case (See [PR 101=
48](https://github.com/bitcoin/bitcoin/pull/10148)), and the=20
entirety of
  the available cache (see `-dbcache`) is now actually used as cache. This =
reduces the flushing
  frequency by a factor 2 or more.
=2D In previous versions, signature validation for transactions has been ca=
ched when the
  transaction is accepted to the mempool. Version 0.15 extends this to cach=
e the entire script
  validity (See [PR 10192](https://github.com/bitcoin/bitcoin/pull/10192)).=
 This means that if a transaction in a block has already been=20
accepted to the
  mempool, the scriptSig does not need to be re-evaluated. Empirical tests =
show that
  this results in new block validation being 40-50% faster.
=2D LevelDB has been upgraded to version 1.20 (See [PR 10544](https://githu=
b.com/bitcoin/bitcoin/pull/10544)). This version contains hardware=20
acceleration for CRC
  on architectures supporting SSE 4.2. As a result, synchronization and blo=
ck validation are now faster.
=2D SHA256 hashing has been optimized for architectures supporting SSE 4 (S=
ee [PR 10821](https://github.com/bitcoin/bitcoin/pull/10821)).=20
SHA256 is around
  50% faster on supported hardware, which results in around 5% faster IBD a=
nd block
  validation. In version 0.15, SHA256 hardware optimization is disabled in =
release builds by
  default, but can be enabled by using `--enable-experimental-asm` when bui=
lding.
=2D Refill of the keypool no longer flushes the wallet between each key whi=
ch resulted in a ~20x speedup in creating a new wallet. Part of=20
this speedup was used to increase the default keypool to 1000 keys to make =
recovery more robust. (See [PR 10831]
(https://github.com/bitcoin/bitcoin/pull/10831)).

=46ee Estimation Improvements
=2D--------------------------

=46ee estimation has been significantly improved in version 0.15, with more=
 accurate fee estimates used by the wallet and a wider range of=20
options for advanced users of the `estimatesmartfee` and `estimaterawfee` R=
PCs (See [PR 10199]
(https://github.com/bitcoin/bitcoin/pull/10199)).

### Changes to internal logic and wallet behavior

=2D Internally, estimates are now tracked on 3 different time horizons. Thi=
s allows for longer targets and means estimates adjust more=20
quickly to changes in conditions.
=2D Estimates can now be *conservative* or *economical*. *Conservative* est=
imates use longer time horizons to produce an estimate which is=20
less susceptible to rapid changes in fee conditions. *Economical* estimates=
 use shorter time horizons and will be more affected by short-
term changes in fee conditions. Economical estimates may be considerably lo=
wer during periods of low transaction activity (for example over=20
weekends), but may result in transactions being unconfirmed if prevailing f=
ees increase rapidly.
=2D By default, the wallet will use conservative fee estimates to increase =
the reliability of transactions being confirmed within the desired=20
target. For transactions that are marked as replaceable, the wallet will us=
e an economical estimate by default, since the fee can be=20
'bumped' if the fee conditions change rapidly (See [PR 10589](https://githu=
b.com/bitcoin/bitcoin/pull/10589)).
=2D Estimates can now be made for confirmation targets up to 1008 blocks (o=
ne week).
=2D More data on historical fee rates is stored, leading to more precise fe=
e estimates.
=2D Transactions which leave the mempool due to eviction or other non-confi=
rmed reasons are now taken into account by the fee estimation=20
logic, leading to more accurate fee estimates.
=2D The fee estimation logic will make sure enough data has been gathered t=
o return a meaningful estimate. If there is insufficient data, a=20
fallback default fee is used.

### Changes to fee estimate RPCs

=2D The `estimatefee` RPC is now deprecated in favor of using only `estimat=
esmartfee` (which is the implementation used by the GUI)
=2D The `estimatesmartfee` RPC interface has been changed (See [PR 10707](h=
ttps://github.com/bitcoin/bitcoin/pull/10707)):
    - The `nblocks` argument has been renamed to `conf_target` (to be consi=
stent with other RPC methods).
    - An `estimate_mode` argument has been added. This argument takes one o=
f the following strings: `CONSERVATIVE`, `ECONOMICAL` or `UNSET`=20
(which defaults to `CONSERVATIVE`).
    - The RPC return object now contains an `errors` member, which returns =
errors encountered during processing.
    - If Bitcoin Knots has not been running for long enough and has not see=
n enough blocks or transactions to produce an accurate fee=20
estimation, an error will be returned (previously a value of -1 was used to=
 indicate an error, which could be confused for a feerate).
=2D A new `estimaterawfee` RPC is added to provide raw fee data. External c=
lients can query and use this data in their own fee estimation=20
logic.

Multi-wallet endpoint support
=2D----------------------------

Bitcoin Knots has supported loading multiple, separate wallets since
v0.13.1.knots20161027. However, due to the RPC API, RPC users could only ac=
cess
a single wallet at a time - accessing multiple wallets over RPC required the
use of multiple RPC users. 0.15.0 adds support for specifying the wallet by
name using a URI path for the RPC endpoint.

To do this, HTTP RPC requests should be send to the `<RPC IP address>:<RPC =
port>/wallet/<wallet name>/` endpoint, for example=20
`127.0.0.1:8332/wallet/wallet1.dat/`.

`bitcoin-cli` commands should be run with a `-rpcwallet` option, for exampl=
e `bitcoin-cli -rpcwallet=3Dwallet1.dat getbalance`.

Additionally, a new `listwallets` RPC method is added to display which wall=
ets are currently loaded. The names returned by this method are=20
the same as those used in the HTTP endpoint and for the `rpcwallet` argumen=
t.

This new wallet endpoint interface should be considered unstable for versio=
n 0.15.0, and there may backwards-incompatible changes in future=20
versions.

The original RPC user based wallet selection continues to work as well, ind=
ependently from the new endpoint support. `rpcauth` users that=20
specify a specific wallet are prohibited from using endpoints to access oth=
ers. However, note that (at least in this version) `listwallets`=20
will always list all wallets on the node, even if access to them has been l=
imited!

Removal of no-fee transactions
=2D-----------------------------

In previous versions of Bitcoin Knots, transactions without a fee would be =
allowed to be relayed if the node's memory pool was empty and=20
the age and value of UTXOs they spent (coin age priority) was sufficiently =
high.

=46or a long time now, this has been effectively useless, due to wide adopt=
ion of Bitcoin as well as regular spam attacks. Since the code no=20
longer has a purpose, support for no-fee transactions has been removed.

Segwit checkpoint
=2D----------------

Since Segwit has activated, this release adds a new checkpoint locking to t=
he first Segwit block. This guarantees no matter what happens,=20
your node will not accept a reorg to attempt theft of Segwit funds. (This i=
sn't a real-world risk anyway, but there's no reason not to=20
guarantee it with a checkpoint.)

Mempool Persistence Across Restarts
=2D----------------------------------

Version 0.13.1.knots20161212 introduced mempool persistence across restarts=
 (the mempool is saved to a `mempool.dat` file in the data=20
directory prior to shutdown and restores the mempool when the node is resta=
rted). Version 0.15 allows this feature to be switched on or off=20
using the `-persistmempool` command-line option (See [PR 9966](https://gith=
ub.com/bitcoin/bitcoin/pull/9966)). By default, the option is=20
set to true, and the mempool is saved on shutdown and reloaded on startup. =
If set to false, the `mempool.dat` file will neither be loaded=20
on startup nor saved on shutdown.

The new `savemempool` RPC can be used to trigger an immediate save of the m=
empool state at any time.

New RPC methods
=2D--------------

Version 0.15 introduces several new RPC methods:

=2D `abortrescan` stops current wallet rescan, e.g. when triggered by an `i=
mportprivkey` call (See [PR 10208]
(https://github.com/bitcoin/bitcoin/pull/10208)).
=2D `combinerawtransaction` accepts a JSON array of raw transactions and co=
mbines them into a single raw transaction (See [PR 10571]
(https://github.com/bitcoin/bitcoin/pull/10571)).
=2D `estimaterawfee` returns raw fee data so that customized logic can be i=
mplemented to analyze the data and calculate estimates. See [Fee=20
Estimation Improvements](#fee-estimation-improvements) for full details on =
changes to the fee estimation logic and interface.
=2D `getchaintxstats` returns statistics about the total number and rate of=
 transactions
  in the chain (See [PR 9733](https://github.com/bitcoin/bitcoin/pull/9733)=
).
=2D `listwallets` lists wallets which are currently loaded. See the *Multi-=
wallet* section
  of these release notes for full details (See [Multi-wallet endpoint suppo=
rt](#multi-wallet-endpoint-support)).
=2D `savemempool` causes the memory pool to immediately update `mempool.dat=
` with its current state.
=2D `uptime` returns the total runtime of the `bitcoind` server since its l=
ast start (See [PR 10400]
(https://github.com/bitcoin/bitcoin/pull/10400)).
=2D `verifyscript` allows verification of a specific Bitcoin Script, option=
ally including a full trace of the evaluation.

Additionally, the `bitcoin-cli` tool now supports a `-getinfo` command line=
 option to fetch information from multiple `get*info` RPC=20
methods. This is intended to replace the deprecated `getinfo` RPC method.

Wallet ZeroMQ publishers
=2D-----------------------

This release includes experimental ZeroMQ publishers for wallet transaction=
s.

See [the ZMQ documentation](zmq.md) for details.

Low-level RPC changes
=2D--------------------

=2D When using Bitcoin Knots in multi-wallet mode, RPC requests for wallet =
methods may specify
  the wallet that they're intended for. See [Multi-wallet endpoint support]=
(#multi-wallet-endpoint-support) for full details.

=2D The `optintorbf` parameter for `createrawtransaction` and `fundrawtrans=
action` has been renamed to `replaceable` to match `bumpfee`.

=2D The new database model no longer stores information about transaction
  versions of unspent outputs (See [Performance improvements](#performance-=
improvements)). This means that:
  - The `gettxout` RPC no longer has a `version` field in the response.
  - The `gettxoutsetinfo` RPC reports `hash_serialized_2` instead of `hash_=
serialized`,
    which does not commit to the transaction versions of unspent outputs, b=
ut does
    commit to the height and coinbase information.
  - The `getutxos` REST path no longer reports the `txvers` field in JSON f=
ormat,
    and always reports 0 for transaction versions in the binary format

=2D The `estimatefee` RPC is deprecated. Clients should switch to using the=
 `estimatesmartfee` RPC, which returns better fee estimates. See=20
[Fee Estimation Improvements](#fee-estimation-improvements) for full detail=
s on changes to the fee estimation logic and interface.

=2D The `gettxoutsetinfo` response now contains `disk_size` and `bogosize` =
instead of
  `bytes_serialized`. The first is a more accurate estimate of actual disk =
usage, but
  is not deterministic. The second is unrelated to disk usage, but is a
  database-independent metric of UTXO set size: it counts every UTXO entry =
as 50 + the
  length of its scriptPubKey (See [PR 10426](https://github.com/bitcoin/bit=
coin/pull/10426)).

=2D `signrawtransaction` can no longer be used to combine multiple transact=
ions into a single transaction. Instead, use the new=20
`combinerawtransaction` RPC (See [PR 10571](https://github.com/bitcoin/bitc=
oin/pull/10571)).

=2D `fundrawtransaction` no longer accepts a `reserveChangeKey` option. Thi=
s option used to allow RPC users to fund a raw transaction using=20
an key from the keypool for the change address without removing it from the=
 available keys in the keypool. The key could then be re-used=20
for a `getnewaddress` call, which could potentially result in confusing or =
dangerous behaviour (See [PR 10784]
(https://github.com/bitcoin/bitcoin/pull/10784)).

=2D `estimatepriority` and `estimatesmartpriority` have been removed. Estim=
ating coin age priority is no longer supported.

=2D In the `getpeerinfo` RPC, the return object for each peer now returns a=
n `addrbind` member, which contains the ip address and port of the=20
connection to the peer. This is in addition to the `addrlocal` member which=
 contains the ip address and port of the local node as reported=20
by the peer (See [PR 10478](https://github.com/bitcoin/bitcoin/pull/10478)).

=2D The `resendwallettransactions` RPC throws an error if the `-walletbroad=
cast` option is set to false (See [PR 10995]
(https://github.com/bitcoin/bitcoin/pull/10995)).

=2D The second argument in the `submitblock` RPC argument has been renamed =
from `parameters` to `dummy`. This argument never had any effect,=20
and the renaming is simply to communicate this fact to the user (See [PR 10=
191](https://github.com/bitcoin/bitcoin/pull/10191))
  (Clients should, however, use positional arguments for `submitblock` in o=
rder to be compatible with BIP 22.)

=2D Mempool entries returned from RPC now include the hash of the entire tr=
ansaction as a `wtxid` key.

Low-level p2p changes
=2D--------------------

Support for a new kind of inventory item MSG_FILTERED_WITNESS_BLOCK has bee=
n added. This extends the functionality of BIP37, used=20
identically to MSG_FILTERED_BLOCK. But whereas MSG_FILTERED_BLOCK returns t=
ransactions with no witness data, MSG_FILTERED_WITNESS_BLOCK=20
returns the transactions serialized along with witness data. No merkle proo=
f for witness inclusion in blocks is provided, but clients can=20
still verify the witness is valid (although possibly not the same witness a=
s in the blockchain).

BIP37 has well-known privacy issues and will likely be deprecated in favor =
of clientside block filtering in future software releases.=20
MSG_FILTERED_WITNESS_BLOCK is provided to enable clients that rely on BIP37=
 to easily add Segregated Witness support immediately until=20
better sync mechanisms gain widespread use.

Warning: BIP37 leaks private data and witness data is not authenticated. Yo=
u must use a trusted node to use this mechanism securely.
