See below for more details. +- In some cases, compact blocks are now relayed before being fully validated as + per BIP152. +- P2P networking has been refactored with a focus on concurrency and + throughput. Network operations are no longer bottlenecked by validation. As a + result, block fetching is several times faster than previous releases in many + cases. +- The UTXO cache now claims unused mempool memory. This speeds up initial block + download as UTXO lookups are a major bottleneck there, and there is no use for + the mempool at that stage. + + +### Manual Pruning + +Bitcoin Core has supported automatically pruning the blockchain since 0.11. +Pruning +the blockchain allows for significant storage space savings as the vast majority +of +the downloaded data can be discarded after processing so very little of it +remains +on the disk. + +Manual block pruning can now be enabled by setting `-prune=1`. Once that is set, +the RPC command `pruneblockchain` can be used to prune the blockchain up to the +specified height or timestamp. + +### `getinfo` has been deprecated + +The `getinfo` RPC command has been deprecated. Each field in the RPC call +has been moved to another command's output with that command also giving +additional information that `getinfo` did not provide. The following table +shows where each field has been moved to: + +|`getinfo` field | Moved to | +|------------------|-------------------------------------------| +`"version"` | `getnetworkinfo()["version"]` +`"protocolversion"`| `getnetworkinfo()["protocolversion"]` +`"walletversion"` | `getwalletinfo()["walletversion"]` +`"balance"` | `getwalletinfo()["balance"]` +`"blocks"` | `getblockchaininfo()["blocks"]` +`"timeoffset"` | `getnetworkinfo()["timeoffset"]` +`"connections"` | `getnetworkinfo()["connections"]` +`"proxy"` | `getnetworkinfo()["networks"][0]["proxy"]` +`"difficulty"` | `getblockchaininfo()["difficulty"]` +`"testnet"` | `getblockchaininfo()["chain"] == "test"` +`"keypoololdest"` | `getwalletinfo()["keypoololdest"]` +`"keypoolsize"` | `getwalletinfo()["keypoolsize"]` +`"unlocked_until"` | `getwalletinfo()["unlocked_until"]` +`"paytxfee"` | `getwalletinfo()["paytxfee"]` +`"relayfee"` | `getnetworkinfo()["relayfee"]` +`"errors"` | `getnetworkinfo()["warnings"]` + +### ZMQ On Windows + +Previously the ZeroMQ notification system was unavailable on Windows +due to various issues with ZMQ. These have been fixed upstream and +now ZMQ can be used on Windows. Please see [this +document](https://github.com/bitcoin/bitcoin/blob/master/doc/zmq.md) for +help with using ZMQ in general. + +### Nested RPC Commands in Debug Console + +The ability to nest RPC commands has been added to the debug console. This +allows users to have the output of a command become the input to another +command without running the commands separately. + +The nested RPC commands use bracket syntax (i.e. `getwalletinfo()`) and can +be nested (i.e. `getblock(getblockhash(1))`). Simple queries can be +done with square brackets where object values are accessed with either an +array index or a non-quoted string (i.e. `listunspent()[0][txid]`). Both +commas and spaces can be used to separate parameters in both the bracket syntax +and normal RPC command syntax. + +### Network Activity Toggle + +A RPC command and GUI toggle have been added to enable or disable all p2p +network activity. The network status icon in the bottom right hand corner +is now the GUI toggle. Clicking the icon will either enable or disable all +p2p network activity. If network activity is disabled, the icon will +be grayed out with an X on top of it. + +Additionally the `setnetworkactive` RPC command has been added which does +the same thing as the GUI icon. The command takes one boolean parameter, +`true` enables networking and `false` disables it. + +### Out-of-sync Modal Info Layer + +When Bitcoin Core is out-of-sync on startup, a semi-transparent information +layer will be shown over top of the normal display. This layer contains +details about the current sync progress and estimates the amount of time +remaining to finish syncing. This layer can also be hidden and subsequently +unhidden by clicking on the progress bar at the bottom of the window. + +### Support for JSON-RPC Named Arguments + +Commands sent over the JSON-RPC interface and through the `bitcoin-cli` binary +can now use named arguments. This follows the [JSON-RPC +specification](http://www.jsonrpc.org/specification) +for passing parameters by-name with an object. + +`bitcoin-cli` has been updated to support this by parsing `name=value` arguments +when the `-named` option is given. + +Some examples: + + src/bitcoin-cli -named help command="help" + src/bitcoin-cli -named getblockhash height=0 + src/bitcoin-cli -named getblock +blockhash=000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f + src/bitcoin-cli -named sendtoaddress address="(snip)" amount="1.0" +subtractfeefromamount=true + +The order of arguments doesn't matter in this case. Named arguments are also +useful to leave out arguments that should stay at their default value. The +rarely-used arguments `comment` and `comment_to` to `sendtoaddress`, for +example, can +be left out. However, this is not yet implemented for many RPC calls, this is +expected to land in a later release. + +The RPC server remains fully backwards compatible with positional arguments. + +### Opt into RBF When Sending + +A new startup option, `-walletrbf`, has been added to allow users to have all +transactions sent opt into RBF support. The default value for this option is +currently `false`, so transactions will not opt into RBF by default. The new +`bumpfee` RPC can be used to replace transactions that opt into RBF. + +### Sensitive Data Is No Longer Stored In Debug Console History + +The debug console maintains a history of previously entered commands that can be +accessed by pressing the Up-arrow key so that users can easily reuse previously +entered commands. Commands which have sensitive information such as passphrases +and +private keys will now have a `(...)` in place of the parameters when accessed +through +the history. + +### Retaining the Mempool Across Restarts + +The mempool will be saved to the data directory prior to shutdown +to a `mempool.dat` file. This file preserves the mempool so that when the node +restarts the mempool can be filled with transactions without waiting for new +transactions +to be created. This will also preserve any changes made to a transaction through +commands such as `prioritisetransaction` so that those changes will not be lost. + +### Final Alert + +The Alert System was [disabled and +deprecated](https://bitcoin.org/en/alert/2016-11-01-alert-retirement) in Bitcoin +Core 0.12.1 and removed in 0.13.0. +The Alert System was retired with a maximum sequence final alert which causes +any nodes +supporting the Alert System to display a static hard-coded "Alert Key +Compromised" message which also +prevents any other alerts from overriding it. This final alert is hard-coded +into this release +so that all old nodes receive the final alert. + +### GUI Changes + +- After resetting the options by clicking the `Reset Options` button + in the options dialog or with the `-resetguioptions` startup option, + the user will be prompted to choose the data directory again. This + is to ensure that custom data directories will be kept after the + option reset which clears the custom data directory set via the choose + datadir dialog. +- Multiple peers can now be selected in the list of peers in the debug + window. This allows for users to ban or disconnect multiple peers + simultaneously instead of banning them one at a time. +- An indicator has been added to the bottom right hand corner of the main + window to indicate whether the wallet being used is a HD wallet. This + icon will be grayed out with an X on top of it if the wallet is not a + HD wallet. + +### Low-level RPC changes + + - `importprunedfunds` only accepts two required arguments. Some versions accept + an optional third arg, which was always ignored. Make sure to never pass more + than two arguments. + - The first boolean argument to `getaddednodeinfo` has been removed. This is + an incompatible change. + - RPC command `getmininginfo` loses the "testnet" field in favor of the more + generic "chain" (which has been present for years). + - A new RPC command `preciousblock` has been added which marks a block as + precious. A precious block will be treated as if it were received earlier + than a competing block. + - A new RPC command `importmulti` has been added which receives an array of + JSON objects representing the intention of importing a public key, a + private key, an address and script/p2sh + - Use of `getrawtransaction` for retrieving confirmed transactions with unspent + outputs has been deprecated. For now this will still work, but in the future + it may change to only be able to retrieve information about transactions in + the mempool or if `txindex` is enabled. + - A new RPC command `getmemoryinfo` has been added which will return + information + about the memory usage of Bitcoin Core. This was added in conjunction with + optimizations to memory management. See [Pull +#8753](https://github.com/bitcoin/bitcoin/pull/8753) + for more information. + - A new RPC command `bumpfee` has been added which allows replacing an + unconfirmed wallet transaction that signaled RBF (see the `-walletrbf` + startup option above) with a new transaction that pays a higher fee, and + should be more likely to get confirmed quickly. + +### HTTP REST Changes + + - UTXO set query (`GET /rest/getutxos//-/- + /.../-.`) responses were changed to return status + code `HTTP_BAD_REQUEST` (400) instead of `HTTP_INTERNAL_SERVER_ERROR` (500) + when requests contain invalid parameters. + +### Minimum Fee Rate Policies + +Since the changes in 0.12 to automatically limit the size of the mempool and +improve the performance of block creation in mining code it has not been +important for relay nodes or miners to set `-minrelaytxfee`. With this release +the following concepts that were tied to this option have been separated out: + +- incremental relay fee used for calculating BIP 125 replacement and mempool + limiting. (1000 satoshis/kB) +- calculation of threshold for a dust output. (effectively 3 * 1000 satoshis/kB) +- minimum fee rate of a package of transactions to be included in a block + created by the mining code. If miners wish to set this minimum they can use +the new `-blockmintxfee` option. (defaults to 1000 satoshis/kB) + +The `-minrelaytxfee` option continues to exist but is recommended to be left +unset. + +### Fee Estimation Changes + +- Since 0.13.2 fee estimation for a confirmation target of 1 block has been + disabled. The fee slider will no longer be able to choose a target of 1 block. + This is only a minor behavior change as there was often insufficient + data for this target anyway. `estimatefee 1` will now always return -1 and + `estimatesmartfee 1` will start searching at a target of 2. + +- The default target for fee estimation is changed to 6 blocks in both the GUI + (previously 25) and for RPC calls (previously 2). + +### Removal of Priority Estimation + +- Estimation of "priority" needed for a transaction to be included within a + target + number of blocks has been removed. The RPC calls are deprecated and will +either + return -1 or 1e24 appropriately. The format for `fee_estimates.dat` has also + changed to no longer save these priority estimates. It will automatically be + converted to the new format which is not readable by prior versions of the + software. + +- Support for "priority" (coin age) transaction sorting for mining is + considered deprecated in Core and will be removed in the next major version. + This is not to be confused with the `prioritisetransaction` RPC which will +remain + supported by Core for adding fee deltas to transactions. + +### P2P connection management + +- Peers manually added through the `-addnode` option or `addnode` RPC now have + their own + limit of eight connections which does not compete with other inbound or +outbound + connection usage and is not subject to the limitation imposed by the +`-maxconnections` + option. + +- New connections to manually added peers are performed more quickly. + +### Introduction of assumed-valid blocks + +- A significant portion of the initial block download time is spent verifying + scripts/signatures. Although the verification must pass to ensure the +security + of the system, no other result from this verification is needed: If the node + knew the history of a given block were valid it could skip checking scripts + for its ancestors. + +- A new configuration option 'assumevalid' is provided to express this knowledge + to the software. Unlike the 'checkpoints' in the past this setting does not + force the use of a particular chain: chains that are consistent with it are + processed quicker, but other chains are still accepted if they'd otherwise + be chosen as best. Also unlike 'checkpoints' the user can configure which + block history is assumed true, this means that even outdated software can + sync more quickly if the setting is updated by the user. + +- Because the validity of a chain history is a simple objective fact it is much + easier to review this setting. As a result the software ships with a default + value adjusted to match the current chain shortly before release. The use + of this default value can be disabled by setting -assumevalid=0 + +### Fundrawtransaction change address reuse + +- Before 0.14, `fundrawtransaction` was by default wallet stateless. In + almost all cases `fundrawtransaction` does add a change-output to the + outputs of the funded transaction. Before 0.14, the used keypool key was + never marked as change-address key and directly returned to the keypool + (leading to address reuse). Before 0.14, calling `getnewaddress` + directly after `fundrawtransaction` did generate the same address as + the change-output address. + +- Since 0.14, fundrawtransaction does reserve the change-output-key from + the keypool by default (optional by setting `reserveChangeKey`, default = + `true`) + +- Users should also consider using `getrawchangeaddress()` in conjunction + with `fundrawtransaction`'s `changeAddress` option. + +### Unused mempool memory used by coincache + +- Before 0.14, memory reserved for mempool (using the `-maxmempool` option) + went unused during initial block download, or IBD. In 0.14, the UTXO DB cache + (controlled with the `-dbcache` option) borrows memory from the mempool + when there is extra memory available. This may result in an increase in + memory usage during IBD for those previously relying on only the `-dbcache` + option to limit memory during that time. + +## 0.14.0 Change log + +Detailed release notes follow. This overview includes changes that affect +behavior, not code moves, minor refactors and string updates.
