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 +-------------- + +Litecoin Core has supported automatically pruning the blockchain since 0.13.2. 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/litecoin-project/litecoin/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 Litecoin 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 `litecoin-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. + +`litecoin-cli` has been updated to support this by parsing `name=value` arguments +when the `-named` option is given. + +Some examples: + + src/litecoin-cli -named help command="help" + src/litecoin-cli -named getblockhash height=0 + src/litecoin-cli -named getblock blockhash=000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f + src/litecoin-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. + +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 in Litecoin Core 0.10.4 and removed in 0.13.2. +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 Litecoin 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. + + - The first positional argument of `createrawtransaction` was renamed from + `transactions` to `inputs`. + + - The argument of `disconnectnode` was renamed from `node` to `address`. + +Client software using these calls with named arguments needs to be updated. + +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 0.13 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: +- 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. + +Mining +------ + +In previous versions, getblocktemplate required segwit support from downstream +clients/miners once the feature activated on the network. In this version, it +now supports non-segwit clients even after activation, by removing all segwit +transactions from the returned block template. This allows non-segwit miners to +continue functioning correctly even after segwit has activated. + +Due to the limitations in previous versions, getblocktemplate also recommended +non-segwit clients to not signal for the segwit version-bit. Since this is no +longer an issue, getblocktemplate now always recommends signalling segwit for +all miners. This is safe because ability to enforce the rule is the only +required criteria for safe activation, not actually producing segwit-enabled +blocks. + +UTXO memory accounting +---------------------- + +Memory usage for the UTXO cache is being calculated more accurately, so that +the configured limit (`-dbcache`) will be respected when memory usage peaks +during cache flushes. The memory accounting in prior releases is estimated to +only account for half the actual peak utilization. + +The default `-dbcache` has also been changed in this release to 450MiB. Users +who currently set `-dbcache` to a high value (e.g. to keep the UTXO more fully +cached in memory) should consider increasing this setting in order to achieve +the same cache performance as prior releases. Users on low-memory systems +(such as systems with 1GB or less) should consider specifying a lower value for +this parameter. + +Additional information relating to running on low-memory systems can be found +here, originally written for Bitcoin but can also be used for Litecoin: +[reducing-bitcoind-memory-usage.md](https://gist.github.com/laanwj/efe29c7661ce9b6620a7). + +Credits +======= + +Thanks to everyone who directly contributed to this release: + +- [The Bitcoin Core Developers](/doc/release-notes) +- Adrian Gallagher +- Charlie Lee +- Loshan T +- Shaolin Fry +- Xinxi Wang \ No newline at end of file diff --git a/doc/litecoin-release-notes/release-notes-0.15.0.1.md b/doc/litecoin-release-notes/release-notes-0.15.0.1.md new file mode 100644 index 000000000..76ec3e0ed --- /dev/null +++ b/doc/litecoin-release-notes/release-notes-0.15.0.1.md @@ -0,0 +1,773 @@ +Litecoin Core version *0.15.0* is now available from: + + + +This is a new major version release, including new features, various bugfixes +and performance improvements, as well as updated translations. + +Please report bugs using the issue tracker at GitHub: + + + +To receive security and update notifications, please subscribe to: + + + +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/Litecoin-Qt` (on Mac) +or `litecoind`/`litecoin-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 +============== + +Litecoin 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. + +Litecoin Core should also work on most other Unix-like systems but is not +frequently tested on them. + +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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/10831)). +- Scrypt hashing has been optimized for architectures supporting SSE 2 (See [PR 362](https://github.com/litecoin-project/litecoin/pull/362)). This boosts scrypt hashing performance by a factor of 2. In version 0.15, scrypt hardware optimization is disabled in release builds by default, but can be enabled by using `--enable-sse2` when building. + +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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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 Litecoin 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. + +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. + +Replace-by-fee control in the GUI +--------------------------------- + +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). + +Multi-wallet support +-------------------- + +Litecoin Core now supports loading multiple, separate wallets (See [PR 8694](https://github.com/bitcoin/bitcoin/pull/8694), [PR 10849](https://github.com/bitcoin/bitcoin/pull/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 Litecoin, either on the command line or in the Litecoin config file. + +**In Litecoin-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. + +Litecoin Core 0.15.0 contains the following changes to the RPC interface and `litecoin-cli` for multi-wallet: + +* When running Litecoin Core with a single wallet, there are **no** changes to the RPC interface or `litecoin-cli`. All RPC calls and `litecoin-cli` commands continue to work as before. +* When running Litecoin Core with multi-wallet, all *node-level* RPC methods continue to work as before. HTTP RPC requests should be send to the normal `:/` endpoint, and `litecoin-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 Litecoin 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 `:/wallet//` endpoint, for example `127.0.0.1:9332/wallet/wallet1.dat/`. `litecoin-cli` commands should be run with a `-rpcwallet` option, for example `litecoin-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. + +Removal of Coin Age Priority +---------------------------- + +In previous versions of Litecoin 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. Litecoin Core 0.15 removes all remaining support for Coin Age Priority (See [PR 9602](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/10208)). +- `combinerawtransaction` accepts a JSON array of raw transactions and combines them into a single raw transaction (See [PR 10571](https://github.com/bitcoin/bitcoin/pull/10571)). +- `estimaterawfee` returns raw fee data so that customized logic can be implemented to analyze the data and calculate estimates. See [Fee Estimation Improvements](#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](https://github.com/bitcoin/bitcoin/pull/9733)). +- `listwallets` lists wallets which are currently loaded. See the *Multi-wallet* section + of these release notes for full details (See [Multi-wallet support](#multi-wallet-support)). +- `uptime` returns the total runtime of the `bitcoind` server since its last start (See [PR 10400](https://github.com/bitcoin/bitcoin/pull/10400)). + +Low-level RPC changes +--------------------- + +- When using Litecoin Core in multi-wallet mode, RPC requests for wallet methods must specify + the wallet that they're intended for. See [Multi-wallet support](#multi-wallet-support) for full details. + +- 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, 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](#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](https://github.com/bitcoin/bitcoin/pull/10426)). + +- `signrawtransaction` can no longer be used to combine multiple transactions into a single transaction. Instead, use the new `combinerawtransaction` RPC (See [PR 10571](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/10784)). + +- `estimatepriority` and `estimatesmartpriority` have been removed. See [Removal of Coin Age Priority](#removal-of-coin-age-priority). + +- The `listunspent` RPC now takes a `query_options` argument (see [PR 8952](https://github.com/bitcoin/bitcoin/pull/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](#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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](#removal-of-coin-age-priority). + +- The `resendwallettransactions` RPC throws an error if the `-walletbroadcast` option is set to false (See [PR 10995](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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](https://github.com/bitcoin/bitcoin/pull/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.
