This means that not even critical security +updates will be released anymore. Without security updates, using a bitcoin +wallet on a XP machine is irresponsible at least. + +In addition to that, with 0.12.x there have been varied reports of Bitcoin Core +randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891) +what the source of these crashes is, but it is likely that upstream +libraries such as Qt are no longer being tested on XP. + +We do not have time nor resources to provide support for an OS that is +end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are +suggested to upgrade to a newer verion of Windows, or install an alternative OS +that is supported. + +No attempt is made to prevent installing or running the software on Windows XP, +you can still do so at your own risk, but do not expect it to work: do not +report issues about Windows XP to the issue tracker. + +Notable changes +=============== + +Database cache memory increased +-------------------------------- + +As a result of growth of the UTXO set, performance with the prior default +database cache of 100 MiB has suffered. +For this reason the default was changed to 300 MiB in this release. + +For nodes on low-memory systems, the database cache can be changed back to +100 MiB (or to another value) by either: + +- Adding `dbcache=100` in bitcoin.conf +- Changing it in the GUI under `Options → Size of database cache` + +Note that the database cache setting has the most performance impact +during initial sync of a node, and when catching up after downtime. + + +bitcoin-cli: arguments privacy +------------------------------ + +The RPC command line client gained a new argument, `-stdin` +to read extra arguments from standard input, one per line until EOF/Ctrl-D. +For example: + + $ src/bitcoin-cli -stdin walletpassphrase + mysecretcode + 120 + ..... press Ctrl-D here to end input + $ + +It is recommended to use this for sensitive information such as wallet +passphrases, as command-line arguments can usually be read from the process +table by any user on the system. + + +C++11 and Python 3 +------------------ + +Various code modernizations have been done. The Bitcoin Core code base has +started using C++11. This means that a C++11-capable compiler is now needed for +building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher. + +When cross-compiling for a target that doesn't have C++11 libraries, configure with +`./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++`. + +For running the functional tests in `qa/rpc-tests`, Python3.4 or higher is now +required. + + +Linux ARM builds +---------------- + +Due to popular request, Linux ARM builds have been added to the uploaded +executables. + +The following extra files can be found in the download directory or torrent: + +- `bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz`: Linux binaries for the most + common 32-bit ARM architecture. +- `bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz`: Linux binaries for the most + common 64-bit ARM architecture. + +ARM builds are still experimental. If you have problems on a certain device or +Linux distribution combination please report them on the bug tracker, it may be +possible to resolve them. + +Note that Android is not considered ARM Linux in this context. The executables +are not expected to work out of the box on Android. + + +Compact Block support (BIP 152) +------------------------------- + +Support for block relay using the Compact Blocks protocol has been implemented +in PR 8068. + +The primary goal is reducing the bandwidth spikes at relay time, though in many +cases it also reduces propagation delay. It is automatically enabled between +compatible peers. +[BIP 152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki) + +As a side-effect, ordinary non-mining nodes will download and upload blocks +faster if those blocks were produced by miners using similar transaction +filtering policies. This means that a miner who produces a block with many +transactions discouraged by your node will be relayed slower than one with +only transactions already in your memory pool. The overall effect of such +relay differences on the network may result in blocks which include widely- +discouraged transactions losing a stale block race, and therefore miners may +wish to configure their node to take common relay policies into consideration. + + +Hierarchical Deterministic Key Generation +----------------------------------------- +Newly created wallets will use hierarchical deterministic key generation +according to BIP32 (keypath m/0'/0'/k'). +Existing wallets will still use traditional key generation. + +Backups of HD wallets, regardless of when they have been created, can +therefore be used to re-generate all possible private keys, even the +ones which haven't already been generated during the time of the backup. +**Attention:** Encrypting the wallet will create a new seed which requires +a new backup! + +Wallet dumps (created using the `dumpwallet` RPC) will contain the deterministic +seed. This is expected to allow future versions to import the seed and all +associated funds, but this is not yet implemented. + +HD key generation for new wallets can be disabled by `-usehd=0`. Keep in +mind that this flag only has affect on newly created wallets. +You can't disable HD key generation once you have created a HD wallet. + +There is no distinction between internal (change) and external keys. + +HD wallets are incompatible with older versions of Bitcoin Core. + +[Pull request](https://github.com/bitcoin/bitcoin/pull/8035/files), [BIP 32](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki) + + +Segregated Witness +------------------ + +The code preparations for Segregated Witness ("segwit"), as described in [BIP +141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki), [BIP +143](https://github.com/bitcoin/bips/blob/master/bip-0143.mediawiki), [BIP +144](https://github.com/bitcoin/bips/blob/master/bip-0144.mediawiki), and [BIP +145](https://github.com/bitcoin/bips/blob/master/bip-0145.mediawiki) are +finished and included in this release. However, BIP 141 does not yet specify +activation parameters on mainnet, and so this release does not support segwit +use on mainnet. Testnet use is supported, and after BIP 141 is updated with +proposed parameters, a future release of Bitcoin Core is expected that +implements those parameters for mainnet. + +Furthermore, because segwit activation is not yet specified for mainnet, +version 0.13.0 will behave similarly as other pre-segwit releases even after a +future activation of BIP 141 on the network. Upgrading from 0.13.0 will be +required in order to utilize segwit-related features on mainnet (such as signal +BIP 141 activation, mine segwit blocks, fully validate segwit blocks, relay +segwit blocks to other segwit nodes, and use segwit transactions in the +wallet, etc). + + +Mining transaction selection ("Child Pays For Parent") +------------------------------------------------------ + +The mining transaction selection algorithm has been replaced with an algorithm +that selects transactions based on their feerate inclusive of unconfirmed +ancestor transactions. This means that a low-fee transaction can become more +likely to be selected if a high-fee transaction that spends its outputs is +relayed. + +With this change, the `-blockminsize` command line option has been removed. + +The command line option `-blockmaxsize` remains an option to specify the +maximum number of serialized bytes in a generated block. In addition, the new +command line option `-blockmaxweight` has been added, which specifies the +maximum "block weight" of a generated block, as defined by [BIP 141 (Segregated +Witness)] (https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki). + +In preparation for Segregated Witness, the mining algorithm has been modified +to optimize transaction selection for a given block weight, rather than a given +number of serialized bytes in a block. In this release, transaction selection +is unaffected by this distinction (as BIP 141 activation is not supported on +mainnet in this release, see above), but in future releases and after BIP 141 +activation, these calculations would be expected to differ. + +For optimal runtime performance, miners using this release should specify +`-blockmaxweight` on the command line, and not specify `-blockmaxsize`. +Additionally (or only) specifying `-blockmaxsize`, or relying on default +settings for both, may result in performance degradation, as the logic to +support `-blockmaxsize` performs additional computation to ensure that +constraint is met. (Note that for mainnet, in this release, the equivalent +parameter for `-blockmaxweight` would be four times the desired +`-blockmaxsize`. See [BIP 141] +(https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki) for additional +details.) + +In the future, the `-blockmaxsize` option may be removed, as block creation is +no longer optimized for this metric. Feedback is requested on whether to +deprecate or keep this command line option in future releases. + + +Reindexing changes +------------------ + +In earlier versions, reindexing did validation while reading through the block +files on disk. These two have now been split up, so that all blocks are known +before validation starts. This was necessary to make certain optimizations that +are available during normal synchronizations also available during reindexing. + +The two phases are distinct in the Bitcoin-Qt GUI. During the first one, +"Reindexing blocks on disk" is shown. During the second (slower) one, +"Processing blocks on disk" is shown. + +It is possible to only redo validation now, without rebuilding the block index, +using the command line option `-reindex-chainstate` (in addition to +`-reindex` which does both). This new option is useful when the blocks on disk +are assumed to be fine, but the chainstate is still corrupted. It is also +useful for benchmarks. + + +Removal of internal miner +-------------------------- + +As CPU mining has been useless for a long time, the internal miner has been +removed in this release, and replaced with a simpler implementation for the +test framework. + +The overall result of this is that `setgenerate` RPC call has been removed, as +well as the `-gen` and `-genproclimit` command-line options. + +For testing, the `generate` call can still be used to mine a block, and a new +RPC call `generatetoaddress` has been added to mine to a specific address. This +works with wallet disabled. + + +New bytespersigop implementation +-------------------------------- + +The former implementation of the bytespersigop filter accidentally broke bare +multisig (which is meant to be controlled by the `permitbaremultisig` option), +since the consensus protocol always counts these older transaction forms as 20 +sigops for backwards compatibility. Simply fixing this bug by counting more +accurately would have reintroduced a vulnerability. It has therefore been +replaced with a new implementation that rather than filter such transactions, +instead treats them (for fee purposes only) as if they were in fact the size +of a transaction actually using all 20 sigops. + + +Low-level P2P changes +---------------------- + +- The optional new p2p message "feefilter" is implemented and the protocol + version is bumped to 70013. Upon receiving a feefilter message from a peer, + a node will not send invs for any transactions which do not meet the filter + feerate. [BIP 133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki) + +- The P2P alert system has been removed in PR #7692 and the `alert` P2P message + is no longer supported. + +- The transaction relay mechanism used to relay one quarter of all transactions + instantly, while queueing up the rest and sending them out in batch. As + this resulted in chains of dependent transactions being reordered, it + systematically hurt transaction relay. The relay code was redesigned in PRs + \#7840 and #8082, and now always batches transactions announcements while also + sorting them according to dependency order. This significantly reduces orphan + transactions. To compensate for the removal of instant relay, the frequency of + batch sending was doubled for outgoing peers. + +- Since PR #7840 the BIP35 `mempool` command is also subject to batch processing. + Also the `mempool` message is no longer handled for non-whitelisted peers when + `NODE_BLOOM` is disabled through `-peerbloomfilters=0`. + +- The maximum size of orphan transactions that are kept in memory until their + ancestors arrive has been raised in PR #8179 from 5000 to 99999 bytes. They + are now also removed from memory when they are included in a block, conflict + with a block, and time out after 20 minutes. + +- We respond at most once to a getaddr request during the lifetime of a + connection since PR #7856. + +- Connections to peers who have recently been the first one to give us a valid + new block or transaction are protected from disconnections since PR #8084. + + +Low-level RPC changes +---------------------- + +- RPC calls have been added to output detailed statistics for individual mempool + entries, as well as to calculate the in-mempool ancestors or descendants of a + transaction: see `getmempoolentry`, `getmempoolancestors`, `getmempooldescendants`. + +- `gettxoutsetinfo` UTXO hash (`hash_serialized`) has changed. There was a divergence between + 32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been + fixed, but this means that the output will be different than from previous versions. + +- Full UTF-8 support in the RPC API. Non-ASCII characters in, for example, + wallet labels have always been malformed because they weren't taken into account + properly in JSON RPC processing. This is no longer the case. This also affects + the GUI debug console. + +- Asm script outputs replacements for OP_NOP2 and OP_NOP3 + + - OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP +65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) + + - OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by [BIP +112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki) + + - The following outputs are affected by this change: + + - RPC `getrawtransaction` (in verbose mode) + - RPC `decoderawtransaction` + - RPC `decodescript` + - REST `/rest/tx/` (JSON format) + - REST `/rest/block/` (JSON format when including extended tx details) + - `bitcoin-tx -json` + +- The sorting of the output of the `getrawmempool` output has changed. + +- New RPC commands: `generatetoaddress`, `importprunedfunds`, `removeprunedfunds`, `signmessagewithprivkey`, + `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry`, + `createwitnessaddress`, `addwitnessaddress`. + +- Removed RPC commands: `setgenerate`, `getgenerate`. + +- New options were added to `fundrawtransaction`: `includeWatching`, `changeAddress`, `changePosition` and `feeRate`. + + +Low-level ZMQ changes +---------------------- + +- Each ZMQ notification now contains an up-counting sequence number that allows + listeners to detect lost notifications. + The sequence number is always the last element in a multi-part ZMQ notification and + therefore backward compatible. Each message type has its own counter. + PR [#7762](https://github.com/bitcoin/bitcoin/pull/7762). + + +0.13.0 Change log +================= + +Detailed release notes follow.
