1Bitcoin Core version 0.13.0 is now available from: 2 3 <https://bitcoin.org/bin/bitcoin-core-0.13.0/> 4 5This is a new major version release, including new features, various bugfixes 6and performance improvements, as well as updated translations. 7 8Please report bugs using the issue tracker at github: 9 10 <https://github.com/bitcoin/bitcoin/issues> 11 12To receive security and update notifications, please subscribe to: 13 14 <https://bitcoincore.org/en/list/announcements/join/> 15 16Compatibility 17============== 18 19Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support), 20an OS initially released in 2001. This means that not even critical security 21updates will be released anymore. Without security updates, using a bitcoin 22wallet on a XP machine is irresponsible at least. 23 24In addition to that, with 0.12.x there have been varied reports of Bitcoin Core 25randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891) 26what the source of these crashes is, but it is likely that upstream 27libraries such as Qt are no longer being tested on XP. 28 29We do not have time nor resources to provide support for an OS that is 30end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are 31suggested to upgrade to a newer verion of Windows, or install an alternative OS 32that is supported. 33 34No attempt is made to prevent installing or running the software on Windows XP, 35you can still do so at your own risk, but do not expect it to work: do not 36report issues about Windows XP to the issue tracker. 37 38Notable changes 39=============== 40 41Database cache memory increased 42-------------------------------- 43 44As a result of growth of the UTXO set, performance with the prior default 45database cache of 100 MiB has suffered. 46For this reason the default was changed to 300 MiB in this release. 47 48For nodes on low-memory systems, the database cache can be changed back to 49100 MiB (or to another value) by either: 50 51- Adding `dbcache=100` in bitcoin.conf 52- Changing it in the GUI under `Options → Size of database cache` 53 54Note that the database cache setting has the most performance impact 55during initial sync of a node, and when catching up after downtime. 56 57 58bitcoin-cli: arguments privacy 59------------------------------ 60 61The RPC command line client gained a new argument, `-stdin` 62to read extra arguments from standard input, one per line until EOF/Ctrl-D. 63For example: 64 65 $ src/bitcoin-cli -stdin walletpassphrase 66 mysecretcode 67 120 68 ..... press Ctrl-D here to end input 69 $ 70 71It is recommended to use this for sensitive information such as wallet 72passphrases, as command-line arguments can usually be read from the process 73table by any user on the system. 74 75 76C++11 and Python 3 77------------------ 78 79Various code modernizations have been done. The Bitcoin Core code base has 80started using C++11. This means that a C++11-capable compiler is now needed for 81building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher. 82 83When cross-compiling for a target that doesn't have C++11 libraries, configure with 84`./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++`. 85 86For running the functional tests in `qa/rpc-tests`, Python3.4 or higher is now 87required. 88 89 90Linux ARM builds 91---------------- 92 93Due to popular request, Linux ARM builds have been added to the uploaded 94executables. 95 96The following extra files can be found in the download directory or torrent: 97 98- `bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz`: Linux binaries for the most 99 common 32-bit ARM architecture. 100- `bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz`: Linux binaries for the most 101 common 64-bit ARM architecture. 102 103ARM builds are still experimental. If you have problems on a certain device or 104Linux distribution combination please report them on the bug tracker, it may be 105possible to resolve them. 106 107Note that Android is not considered ARM Linux in this context. The executables 108are not expected to work out of the box on Android. 109 110 111Compact Block support (BIP 152) 112------------------------------- 113 114Support for block relay using the Compact Blocks protocol has been implemented 115in PR 8068. 116 117The primary goal is reducing the bandwidth spikes at relay time, though in many 118cases it also reduces propagation delay. It is automatically enabled between 119compatible peers. 120[BIP 152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki) 121 122As a side-effect, ordinary non-mining nodes will download and upload blocks 123faster if those blocks were produced by miners using similar transaction 124filtering policies. This means that a miner who produces a block with many 125transactions discouraged by your node will be relayed slower than one with 126only transactions already in your memory pool. The overall effect of such 127relay differences on the network may result in blocks which include widely- 128discouraged transactions losing a stale block race, and therefore miners may 129wish to configure their node to take common relay policies into consideration. 130 131 132Hierarchical Deterministic Key Generation 133----------------------------------------- 134Newly created wallets will use hierarchical deterministic key generation 135according to BIP32 (keypath m/0'/0'/k'). 136Existing wallets will still use traditional key generation. 137 138Backups of HD wallets, regardless of when they have been created, can 139therefore be used to re-generate all possible private keys, even the 140ones which haven't already been generated during the time of the backup. 141**Attention:** Encrypting the wallet will create a new seed which requires 142a new backup! 143 144Wallet dumps (created using the `dumpwallet` RPC) will contain the deterministic 145seed. This is expected to allow future versions to import the seed and all 146associated funds, but this is not yet implemented. 147 148HD key generation for new wallets can be disabled by `-usehd=0`. Keep in 149mind that this flag only has affect on newly created wallets. 150You can't disable HD key generation once you have created a HD wallet. 151 152There is no distinction between internal (change) and external keys. 153 154HD wallets are incompatible with older versions of Bitcoin Core. 155 156[Pull request](https://github.com/bitcoin/bitcoin/pull/8035/files), [BIP 32](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki) 157 158 159Segregated Witness 160------------------ 161 162The code preparations for Segregated Witness ("segwit"), as described in [BIP 163141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki), [BIP 164143](https://github.com/bitcoin/bips/blob/master/bip-0143.mediawiki), [BIP 165144](https://github.com/bitcoin/bips/blob/master/bip-0144.mediawiki), and [BIP 166145](https://github.com/bitcoin/bips/blob/master/bip-0145.mediawiki) are 167finished and included in this release. However, BIP 141 does not yet specify 168activation parameters on mainnet, and so this release does not support segwit 169use on mainnet. Testnet use is supported, and after BIP 141 is updated with 170proposed parameters, a future release of Bitcoin Core is expected that 171implements those parameters for mainnet. 172 173Furthermore, because segwit activation is not yet specified for mainnet, 174version 0.13.0 will behave similarly as other pre-segwit releases even after a 175future activation of BIP 141 on the network. Upgrading from 0.13.0 will be 176required in order to utilize segwit-related features on mainnet (such as signal 177BIP 141 activation, mine segwit blocks, fully validate segwit blocks, relay 178segwit blocks to other segwit nodes, and use segwit transactions in the 179wallet, etc). 180 181 182Mining transaction selection ("Child Pays For Parent") 183------------------------------------------------------ 184 185The mining transaction selection algorithm has been replaced with an algorithm 186that selects transactions based on their feerate inclusive of unconfirmed 187ancestor transactions. This means that a low-fee transaction can become more 188likely to be selected if a high-fee transaction that spends its outputs is 189relayed. 190 191With this change, the `-blockminsize` command line option has been removed. 192 193The command line option `-blockmaxsize` remains an option to specify the 194maximum number of serialized bytes in a generated block. In addition, the new 195command line option `-blockmaxweight` has been added, which specifies the 196maximum "block weight" of a generated block, as defined by [BIP 141 (Segregated 197Witness)] (https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki). 198 199In preparation for Segregated Witness, the mining algorithm has been modified 200to optimize transaction selection for a given block weight, rather than a given 201number of serialized bytes in a block. In this release, transaction selection 202is unaffected by this distinction (as BIP 141 activation is not supported on 203mainnet in this release, see above), but in future releases and after BIP 141 204activation, these calculations would be expected to differ. 205 206For optimal runtime performance, miners using this release should specify 207`-blockmaxweight` on the command line, and not specify `-blockmaxsize`. 208Additionally (or only) specifying `-blockmaxsize`, or relying on default 209settings for both, may result in performance degradation, as the logic to 210support `-blockmaxsize` performs additional computation to ensure that 211constraint is met. (Note that for mainnet, in this release, the equivalent 212parameter for `-blockmaxweight` would be four times the desired 213`-blockmaxsize`. See [BIP 141] 214(https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki) for additional 215details.) 216 217In the future, the `-blockmaxsize` option may be removed, as block creation is 218no longer optimized for this metric. Feedback is requested on whether to 219deprecate or keep this command line option in future releases. 220 221 222Reindexing changes 223------------------ 224 225In earlier versions, reindexing did validation while reading through the block 226files on disk. These two have now been split up, so that all blocks are known 227before validation starts. This was necessary to make certain optimizations that 228are available during normal synchronizations also available during reindexing. 229 230The two phases are distinct in the Bitcoin-Qt GUI. During the first one, 231"Reindexing blocks on disk" is shown. During the second (slower) one, 232"Processing blocks on disk" is shown. 233 234It is possible to only redo validation now, without rebuilding the block index, 235using the command line option `-reindex-chainstate` (in addition to 236`-reindex` which does both). This new option is useful when the blocks on disk 237are assumed to be fine, but the chainstate is still corrupted. It is also 238useful for benchmarks. 239 240 241Removal of internal miner 242-------------------------- 243 244As CPU mining has been useless for a long time, the internal miner has been 245removed in this release, and replaced with a simpler implementation for the 246test framework. 247 248The overall result of this is that `setgenerate` RPC call has been removed, as 249well as the `-gen` and `-genproclimit` command-line options. 250 251For testing, the `generate` call can still be used to mine a block, and a new 252RPC call `generatetoaddress` has been added to mine to a specific address. This 253works with wallet disabled. 254 255 256New bytespersigop implementation 257-------------------------------- 258 259The former implementation of the bytespersigop filter accidentally broke bare 260multisig (which is meant to be controlled by the `permitbaremultisig` option), 261since the consensus protocol always counts these older transaction forms as 20 262sigops for backwards compatibility. Simply fixing this bug by counting more 263accurately would have reintroduced a vulnerability. It has therefore been 264replaced with a new implementation that rather than filter such transactions, 265instead treats them (for fee purposes only) as if they were in fact the size 266of a transaction actually using all 20 sigops. 267 268 269Low-level P2P changes 270---------------------- 271 272- The optional new p2p message "feefilter" is implemented and the protocol 273 version is bumped to 70013. Upon receiving a feefilter message from a peer, 274 a node will not send invs for any transactions which do not meet the filter 275 feerate. [BIP 133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki) 276 277- The P2P alert system has been removed in PR #7692 and the `alert` P2P message 278 is no longer supported. 279 280- The transaction relay mechanism used to relay one quarter of all transactions 281 instantly, while queueing up the rest and sending them out in batch. As 282 this resulted in chains of dependent transactions being reordered, it 283 systematically hurt transaction relay. The relay code was redesigned in PRs 284 \#7840 and #8082, and now always batches transactions announcements while also 285 sorting them according to dependency order. This significantly reduces orphan 286 transactions. To compensate for the removal of instant relay, the frequency of 287 batch sending was doubled for outgoing peers. 288 289- Since PR #7840 the BIP35 `mempool` command is also subject to batch processing. 290 Also the `mempool` message is no longer handled for non-whitelisted peers when 291 `NODE_BLOOM` is disabled through `-peerbloomfilters=0`. 292 293- The maximum size of orphan transactions that are kept in memory until their 294 ancestors arrive has been raised in PR #8179 from 5000 to 99999 bytes. They 295 are now also removed from memory when they are included in a block, conflict 296 with a block, and time out after 20 minutes. 297 298- We respond at most once to a getaddr request during the lifetime of a 299 connection since PR #7856. 300 301- Connections to peers who have recently been the first one to give us a valid 302 new block or transaction are protected from disconnections since PR #8084. 303 304 305Low-level RPC changes 306---------------------- 307 308- RPC calls have been added to output detailed statistics for individual mempool 309 entries, as well as to calculate the in-mempool ancestors or descendants of a 310 transaction: see `getmempoolentry`, `getmempoolancestors`, `getmempooldescendants`. 311 312- `gettxoutsetinfo` UTXO hash (`hash_serialized`) has changed. There was a divergence between 313 32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been 314 fixed, but this means that the output will be different than from previous versions. 315 316- Full UTF-8 support in the RPC API. Non-ASCII characters in, for example, 317 wallet labels have always been malformed because they weren't taken into account 318 properly in JSON RPC processing. This is no longer the case. This also affects 319 the GUI debug console. 320 321- Asm script outputs replacements for OP_NOP2 and OP_NOP3 322 323 - OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP 32465](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) 325 326 - OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by [BIP 327112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki) 328 329 - The following outputs are affected by this change: 330 331 - RPC `getrawtransaction` (in verbose mode) 332 - RPC `decoderawtransaction` 333 - RPC `decodescript` 334 - REST `/rest/tx/` (JSON format) 335 - REST `/rest/block/` (JSON format when including extended tx details) 336 - `bitcoin-tx -json` 337 338- The sorting of the output of the `getrawmempool` output has changed. 339 340- New RPC commands: `generatetoaddress`, `importprunedfunds`, `removeprunedfunds`, `signmessagewithprivkey`, 341 `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry`, 342 `createwitnessaddress`, `addwitnessaddress`. 343 344- Removed RPC commands: `setgenerate`, `getgenerate`. 345 346- New options were added to `fundrawtransaction`: `includeWatching`, `changeAddress`, `changePosition` and `feeRate`. 347 348 349Low-level ZMQ changes 350---------------------- 351 352- Each ZMQ notification now contains an up-counting sequence number that allows 353 listeners to detect lost notifications. 354 The sequence number is always the last element in a multi-part ZMQ notification and 355 therefore backward compatible. Each message type has its own counter. 356 PR [#7762](https://github.com/bitcoin/bitcoin/pull/7762). 357 358 3590.13.0 Change log 360================= 361 362Detailed release notes follow.
