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).

The first time you run version 0.15.0, 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.

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 fee 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

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 10.8+, and Windows Vista and later. Windows XP is not supported.

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

Notes for 0.15.0

Current SegWit support

Version 0.15.0 supports adding a segregated witness address via the addwitnessaddress RPC, but please note that this is a testing/expert RPC, which does not guarantee recovery from backup. Only use this RPC if you know what you are doing. More complete wallet support for segregated witness is coming in a next version.

Rescanning with encrypted wallets

As in previous versions, when using an encrypted HD wallet, the keypool cannot be topped up without unlocking the wallet. This means that currently, in order to recover from a backup of an encrypted HD wallet, the user must unlock the wallet with a really long timeout and manually trigger a rescan, otherwise they risk missing some keys when auto-topup cannot run. Unfortunately there is no rescan RPC in this version, that will be included in a future version, so for now a rescan can be triggered using one of the import* commands, using a dummy address generated by another (trusted) wallet.

Notable changes

Performance Improvements

Version 0.15 contains a number of significant performance improvements, which make Initial Block Download, startup, transaction and block validation much faster:

  • The chainstate database (which is used for tracking UTXOs) has been changed from a per-transaction model to a per-output model (See PR 10195). Advantages of this model are that it:

    • avoids the CPU overhead of deserializing and serializing the unused outputs;
    • 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.

  • Earlier versions experienced a spike in memory usage while flushing UTXO 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 10148), and the entirety of the available cache (see -dbcache) is now actually used as cache. This reduces the flushing frequency by a factor 2 or more.

  • In previous versions, signature validation for transactions has been cached when the transaction is accepted to the mempool. Version 0.15 extends this to cache the entire script validity (See PR 10192). This means that if a transaction in a block has already been 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.

  • LevelDB has been upgraded to version 1.20 (See PR 10544). This version contains hardware acceleration for CRC on architectures supporting SSE 4.2. As a result, synchronization and block validation are now faster.

  • SHA256 hashing has been optimized for architectures supporting SSE 4 (See PR 10821). SHA256 is around 50% faster on supported hardware, which results in around 5% faster IBD and 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 building.

  • Refill of the keypool no longer flushes the wallet between each key which resulted in a ~20x speedup in creating a new wallet. Part of this speedup was used to increase the default keypool to 1000 keys to make recovery more robust. (See PR 10831).

Fee Estimation Improvements

Fee estimation has been significantly improved in version 0.15, with more accurate fee estimates used by the wallet and a wider range of options for advanced users of the estimatesmartfee and estimaterawfee RPCs (See PR 10199).

Changes to internal logic and wallet behavior

  • Internally, estimates are now tracked on 3 different time horizons. This allows for longer targets and means estimates adjust more quickly to changes in conditions.
  • Estimates can now be conservative or economical. Conservative estimates use longer time horizons to produce an estimate which is 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 lower during periods of low transaction activity (for example over weekends), but may result in transactions being unconfirmed if prevailing fees increase rapidly.
  • By default, the wallet will use conservative fee estimates to increase the reliability of transactions being confirmed within the desired target. For transactions that are marked as replaceable, the wallet will use an economical estimate by default, since the fee can be 'bumped' if the fee conditions change rapidly (See PR 10589).
  • Estimates can now be made for confirmation targets up to 1008 blocks (one week).
  • More data on historical fee rates is stored, leading to more precise fee estimates.
  • Transactions which leave the mempool due to eviction or other non-confirmed reasons are now taken into account by the fee estimation logic, leading to more accurate fee estimates.
  • The fee estimation logic will make sure enough data has been gathered to return a meaningful estimate. If there is insufficient data, a fallback default fee is used.

Changes to fee estimate RPCs

  • The estimatefee RPC is now deprecated in favor of using only estimatesmartfee (which is the implementation used by the GUI)
  • The estimatesmartfee RPC interface has been changed (See PR 10707):
    • The nblocks argument has been renamed to conf_target (to be consistent with other RPC methods).
    • An estimate_mode argument has been added. This argument takes one of the following strings: CONSERVATIVE, ECONOMICAL or UNSET (which defaults to CONSERVATIVE).
    • The RPC return object now contains an errors member, which returns errors encountered during processing.
    • If Bitcoin Core has not been running for long enough and has not seen enough blocks or transactions to produce an accurate fee estimation, an error will be returned (previously a value of -1 was used to indicate an error, which could be confused for a feerate).
  • A new estimaterawfee RPC is added to provide raw fee data. External clients can query and use this data in their own fee estimation logic.

Multi-wallet support

Bitcoin Core now supports loading multiple, separate wallets (See PR 8694, PR 10849). The wallets are completely separated, with individual balances, keys and received transactions.

Multi-wallet is enabled by using more than one -wallet argument when starting Bitcoin, either on the command line or in the Bitcoin config file.

In Bitcoin-Qt, only the first wallet will be displayed and accessible for creating and signing transactions. GUI selectable multiple wallets will be supported in a future version. However, even in 0.15 other loaded wallets will remain synchronized to the node's current tip in the background. This can be useful if running a pruned node, since loading a wallet where the most recent sync is beyond the pruned height results in having to download and revalidate the whole blockchain. Continuing to synchronize all wallets in the background avoids this problem.

Bitcoin Core 0.15.0 contains the following changes to the RPC interface and bitcoin-cli for multi-wallet:

  • When running Bitcoin Core with a single wallet, there are no changes to the RPC interface or bitcoin-cli. All RPC calls and bitcoin-cli commands continue to work as before.
  • When running Bitcoin Core with multi-wallet, all node-level RPC methods continue to work as before. HTTP RPC requests should be send to the normal <RPC IP address>:<RPC port> endpoint, and bitcoin-cli commands should be run as before. A node-level RPC method is any method which does not require access to the wallet.
  • When running Bitcoin Core with multi-wallet, wallet-level RPC methods must specify the wallet for which they're intended in every request. HTTP RPC requests should be send to the <RPC IP address>:<RPC port>/wallet/<wallet name> endpoint, for example 127.0.0.1:8332/wallet/wallet1.dat. bitcoin-cli commands should be run with a -rpcwallet option, for example bitcoin-cli -rpcwallet=wallet1.dat getbalance.
  • A new node-level listwallets RPC method is added to display which wallets are currently loaded. The names returned by this method are the same as those used in the HTTP endpoint and for the rpcwallet argument.

Note that while multi-wallet is now fully supported, the RPC multi-wallet interface should be considered unstable for version 0.15.0, and there may backwards-incompatible changes in future versions.

Replace-by-fee control in the GUI

Bitcoin Core has supported creating opt-in replace-by-fee (RBF) transactions since version 0.12.0, and since version 0.14.0 has included a bumpfee RPC method to replace unconfirmed opt-in RBF transactions with a new transaction that pays a higher fee.

In version 0.15, creating an opt-in RBF transaction and replacing the unconfirmed transaction with a higher-fee transaction are both supported in the GUI (See PR 9592).

Removal of Coin Age Priority

In previous versions of Bitcoin Core, a portion of each block could be reserved for transactions based on the age and value of UTXOs they spent. This concept (Coin Age Priority) is a policy choice by miners, and there are no consensus rules around the inclusion of Coin Age Priority transactions in blocks. In practice, only a few miners continue to use Coin Age Priority for transaction selection in blocks. Bitcoin Core 0.15 removes all remaining support for Coin Age Priority (See PR 9602). This has the following implications:

  • The concept of free transactions has been removed. High Coin Age Priority transactions would previously be allowed to be relayed even if they didn't attach a miner fee. This is no longer possible since there is no concept of Coin Age Priority. The -limitfreerelay and -relaypriority options which controlled relay of free transactions have therefore been removed.
  • The -sendfreetransactions option has been removed, since almost all miners do not include transactions which do not attach a transaction fee.
  • The -blockprioritysize option has been removed.
  • The estimatepriority and estimatesmartpriority RPCs have been removed.
  • The getmempoolancestors, getmempooldescendants, getmempoolentry and getrawmempool RPCs no longer return startingpriority and currentpriority.
  • The prioritisetransaction RPC no longer takes a priority_delta argument, which is replaced by a dummy argument for backwards compatibility with clients using positional arguments. The RPC is still used to change the apparent fee-rate of the transaction by using the fee_delta argument.
  • -minrelaytxfee can now be set to 0. If minrelaytxfee is set, then fees smaller than minrelaytxfee (per kB) are rejected from relaying, mining and transaction creation. This defaults to 1000 satoshi/kB.
  • The -printpriority option has been updated to only output the fee rate and hash of transactions included in a block by the mining code.

Mempool Persistence Across Restarts

Version 0.14 introduced mempool persistence across restarts (the mempool is saved to a mempool.dat file in the data directory prior to shutdown and restores the mempool when the node is restarted). Version 0.15 allows this feature to be switched on or off using the -persistmempool command-line option (See PR 9966). By default, the option is set to true, and the mempool is saved on shutdown and reloaded on startup. If set to false, the mempool.dat file will not be loaded on startup or saved on shutdown.

New RPC methods

Version 0.15 introduces several new RPC methods:

  • abortrescan stops current wallet rescan, e.g. when triggered by an importprivkey call (See PR 10208).
  • combinerawtransaction accepts a JSON array of raw transactions and combines them into a single raw transaction (See PR 10571).
  • estimaterawfee returns raw fee data so that customized logic can be implemented to analyze the data and calculate estimates. See Fee Estimation Improvements for full details on changes to the fee estimation logic and interface.
  • getchaintxstats returns statistics about the total number and rate of transactions in the chain (See PR 9733).
  • listwallets lists wallets which are currently loaded. See the Multi-wallet section of these release notes for full details (See Multi-wallet support).
  • uptime returns the total runtime of the bitcoind server since its last start (See PR 10400).

Low-level RPC changes

  • When using Bitcoin Core in multi-wallet mode, RPC requests for wallet methods must specify the wallet that they're intended for. See Multi-wallet support for full details.

  • The new database model no longer stores information about transaction versions of unspent outputs (See 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, but does commit to the height and coinbase information.
    • The getutxos REST path no longer reports the txvers field in JSON format, and always reports 0 for transaction versions in the binary format

  • The estimatefee RPC is deprecated. Clients should switch to using the estimatesmartfee RPC, which returns better fee estimates. See Fee Estimation Improvements for full details on changes to the fee estimation logic and interface.

  • 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).

  • signrawtransaction can no longer be used to combine multiple transactions into a single transaction. Instead, use the new combinerawtransaction RPC (See PR 10571).

  • fundrawtransaction no longer accepts a reserveChangeKey option. This option used to allow RPC users to fund a raw transaction using 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 for a getnewaddress call, which could potentially result in confusing or dangerous behaviour (See PR 10784).

  • estimatepriority and estimatesmartpriority have been removed. See Removal of Coin Age Priority.

  • The listunspent RPC now takes a query_options argument (see PR 8952), which is a JSON object containing one or more of the following members:

    • minimumAmount - a number specifying the minimum value of each UTXO
    • maximumAmount - a number specifying the maximum value of each UTXO
    • maximumCount - a number specifying the minimum number of UTXOs
    • minimumSumAmount - a number specifying the minimum sum value of all UTXOs

  • The getmempoolancestors, getmempooldescendants, getmempoolentry and getrawmempool RPCs no longer return startingpriority and currentpriority. See Removal of Coin Age Priority.

  • The dumpwallet RPC now returns the full absolute path to the dumped wallet. It used to return no value, even if successful (See PR 9740).

  • In the getpeerinfo RPC, the return object for each peer now returns an addrbind member, which contains the ip address and port of the 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 by the peer (See PR 10478).

  • The disconnectnode RPC can now disconnect a node specified by node ID (as well as by IP address/port). To disconnect a node based on node ID, call the RPC with the new nodeid argument (See PR 10143).

  • The second argument in prioritisetransaction has been renamed from priority_delta to dummy since Bitcoin Core no longer has a concept of coin age priority. The dummy argument has no functional effect, but is retained for positional argument compatibility. See Removal of Coin Age Priority.

  • The resendwallettransactions RPC throws an error if the -walletbroadcast option is set to false (See PR 10995).

  • The second argument in the submitblock RPC argument has been renamed from parameters to dummy. This argument never had any effect, and the renaming is simply to communicate this fact to the user (See PR 10191) (Clients should, however, use positional arguments for submitblock in order to be compatible with BIP 22.)

  • The verbose argument of getblock has been renamed to verbosity and now takes an integer from 0 to 2. Verbose level 0 is equivalent to verbose=false. Verbose level 1 is equivalent to verbose=true. Verbose level 2 will give the full transaction details of each transaction in the output as given by getrawtransaction. The old behavior of using the verbose named argument and a boolean value is still maintained for compatibility.

  • Error codes have been updated to be more accurate for the following error cases (See PR 9853):

    • getblock now returns RPC_MISC_ERROR if the block can't be found on disk (for example if the block has been pruned). Previously returned RPC_INTERNAL_ERROR.
    • pruneblockchain now returns RPC_MISC_ERROR if the blocks cannot be pruned because the node is not in pruned mode. Previously returned RPC_METHOD_NOT_FOUND.
    • pruneblockchain now returns RPC_INVALID_PARAMETER if the blocks cannot be pruned because the supplied timestamp is too late. Previously returned RPC_INTERNAL_ERROR.
    • pruneblockchain now returns RPC_MISC_ERROR if the blocks cannot be pruned because the blockchain is too short. Previously returned RPC_INTERNAL_ERROR.
    • setban now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the supplied IP address or subnet is invalid. Previously returned RPC_CLIENT_NODE_ALREADY_ADDED.
    • setban now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the user tries to unban a node that has not previously been banned. Previously returned RPC_MISC_ERROR.
    • removeprunedfunds now returns RPC_WALLET_ERROR if bitcoind is unable to remove the transaction. Previously returned RPC_INTERNAL_ERROR.
    • removeprunedfunds now returns RPC_INVALID_PARAMETER if the transaction does not exist in the wallet. Previously returned RPC_INTERNAL_ERROR.
    • fundrawtransaction now returns RPC_INVALID_ADDRESS_OR_KEY if an invalid change address is provided. Previously returned RPC_INVALID_PARAMETER.
    • fundrawtransaction now returns RPC_WALLET_ERROR if bitcoind is unable to create the transaction. The error message provides further details. Previously returned RPC_INTERNAL_ERROR.
    • bumpfee now returns RPC_INVALID_PARAMETER if the provided transaction has descendants in the wallet. Previously returned RPC_MISC_ERROR.
    • bumpfee now returns RPC_INVALID_PARAMETER if the provided transaction has descendants in the mempool. Previously returned RPC_MISC_ERROR.
    • bumpfee now returns RPC_WALLET_ERROR if the provided transaction has has been mined or conflicts with a mined transaction. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
    • bumpfee now returns RPC_WALLET_ERROR if the provided transaction is not BIP 125 replaceable. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
    • bumpfee now returns RPC_WALLET_ERROR if the provided transaction has already been bumped by a different transaction. Previously returned RPC_INVALID_REQUEST.
    • bumpfee now returns RPC_WALLET_ERROR if the provided transaction contains inputs which don't belong to this wallet. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
    • bumpfee now returns RPC_WALLET_ERROR if the provided transaction has multiple change outputs. Previously returned RPC_MISC_ERROR.
    • bumpfee now returns RPC_WALLET_ERROR if the provided transaction has no change output. Previously returned RPC_MISC_ERROR.
    • bumpfee now returns RPC_WALLET_ERROR if the fee is too high. Previously returned RPC_MISC_ERROR.
    • bumpfee now returns RPC_WALLET_ERROR if the fee is too low. Previously returned RPC_MISC_ERROR.
    • bumpfee now returns RPC_WALLET_ERROR if the change output is too small to bump the fee. Previously returned RPC_MISC_ERROR.
