This fixes an integer signedness (within the LAN) to cause a denial of service or possibly have unspecified other impact. +Performance Improvements +-------------- + +Validation speed and network propagation performance have been greatly +improved, leading to much shorter sync and initial block download times. + +- The script signature cache has been reimplemented as a "cuckoo cache", + allowing for more signatures to be cached and faster lookups. +- Assumed-valid blocks have been introduced which allows script validation to + be skipped for ancestors of known-good blocks, without changing the security + model. 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 +-------------- + +Dogecoin Core introduces pruning the blockchain in 1.14. 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` 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 Dogecoin 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 +----------------------------------------------------------- + This only affects users that have explicitly enabled UPnP through the GUI setting or through the `-upnp` option, as since the last UPnP vulnerability (in Bitcoin Core 0.10.3) it has been disabled by default. @@ -97,13 +250,13 @@ possible.

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 1.14, `fundrawtransaction` was by default wallet stateless. In + almost all cases `fundrawtransaction` does add a change-output to the + outputs of the funded transaction. Before 1.14, the used keypool key was + never marked as change-address key and directly returned to the keypool + (leading to address reuse). Before 1.14, 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 1.14, 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. +>>>>>>> Update release notes for 1.14 (#1464) + Credits ======= @@ -143,6 +447,33 @@ Thanks to everyone who directly contributed to this release: - Gregory Sanders - Jonas Schnelli - Matt Corallo +<<<<<<< HEAD +======= +- Matthew King +- matthias +- Max Keller +- Micha +- Michael Ford +- Michael Rotarius +- Mitchell Cash +- mrbandrews +- mruddy +- Nicolas DORIER +- nomnombtc +- Patrick Lodder +- Patrick Strateman +- Pavel JanÃk +- Pedro Branco +- Peter Todd +- Pieter Wuille +- poole\_party +- practicalswift +- R E Broadley +- randy-waterhouse +- Richard Kiss +- Robert McLaughlin +- rodasmith +- Ross Nicoll - Russell Yanofsky - Shigeya Suzuki - Wladimir J. van der Laan |
