Signed binaries and source code available from:

<https://github.com/BTCGPU/BTCGPU/releases/tag/v0.17.1>

This is a new major version release, including new features, various bugfixes and performance improvements, as well as updated translations. It is based on Bitcoin Core 0.17.1. https://github.com/bitcoin/bitcoin/releases/tag/v0.17.1

Please report bugs using the issue tracker at GitHub:

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/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

If your node has a txindex, the txindex db will be migrated the first time you run 0.17.1 or newer, which may take up to a few hours. Your node will not be functional until this migration completes.

Downgrading warning

Wallets created in 0.17.1 and later are not compatible with versions prior to 0.17.1 and will not work if you try to use newly created wallets in older versions. Existing wallets that were created with older versions are not affected by this.

Compatibility

BTG Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows 10. Windows Vista and later should work, while Windows XP is not supported.

BTG Core should also work on most other Unix-like systems but is not frequently tested on them.

From 0.17.1 onwards macOS <10.10 is no longer supported. 0.17.1 is built using Qt 5.9.x, which doesn't support versions of macOS older than 10.10.

Notable changes

This release pulls in updates, bugfixes, and new features to BTG Core from Bitcoin Core version 0.16.0 through 0.17.1. The following is a compiled list of all applicable changes for the v0.17.1 BTG release.

Compact Block support (BIP 152)

Support for block relay using the Compact Blocks protocol has been implemented for BTG.

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

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.

GUI changes

• Block storage can be limited under Preferences, in the Main tab. Undoing this setting requires downloading the full blockchain again. This mode is incompatible with -txindex and -rescan.
• Uses of "µBTC" in the GUI now also show the more colloquial term "bits", specified in BIP176.
• The option to reuse a previous address has now been removed. This was justified by the need to "resend" an invoice, but now that we have the request history, that need should be gone.
• Support for searching by TXID has been added, rather than just address and label.
• A "Use available balance" option has been added to the send coins dialog, to add the remaining available wallet balance to a transaction output.
• A toggle for unblinding the password fields on the password dialog has been added.

Wallet changes

Segwit Wallet

BTG Core 0.17.1 introduces full support for segwit in the wallet and user interfaces. A new -addresstype argument has been added, which supports legacy, p2sh-segwit (default), and bech32 addresses. It controls what kind of addresses are produced by getnewaddress, getaccountaddress, and createmultisigaddress. A -changetype argument has also been added, with the same options, and by default equal to -addresstype, to control which kind of change is used.

A new address_type parameter has been added to the getnewaddress and addmultisigaddress RPCs to specify which type of address to generate. A change_type argument has been added to the fundrawtransaction RPC to override the -changetype argument for specific transactions.

• All segwit addresses created through getnewaddress or *multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a segwit address will work, as long as the wallet file is up to date.
• All segwit keys in the wallet get an implicit redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
• All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a segwit address will work

Note that some RPCs do not yet support segwit addresses. Notably, signmessage/verifymessage doesn't support segwit addresses, nor does importmulti at this time. Support for segwit in those RPCs will continue to be added in future versions.

P2WPKH change outputs are now used by default if any destination in the transaction is a P2WPKH or P2WSH output. This is done to ensure the change output is as indistinguishable from the other outputs as possible in either case.

BIP173 (Bech32) Address support ("bc1..." addresses)

Full support for native segwit addresses (BIP173 / Bech32) has now been added. This includes the ability to send to BIP173 addresses (including non-v0 ones), and generating these addresses (including as default new addresses, see above).

A checkbox has been added to the GUI to select whether a Bech32 address or P2SH-wrapped address should be generated when using segwit addresses. When launched with -addresstype=bech32 it is checked by default. When launched with -addresstype=legacy it is unchecked and disabled.

Upgrading non-HD wallets to HD wallets

Since BTG Core 0.15, creating new BIP 32 Hierarchical Deterministic wallets has been supported by BTG Core but old non-HD wallets could not be upgraded to HD. Now non-HD wallets can be upgraded to HD using the -upgradewallet command line option. This upgrade will result in the all keys in the keypool being marked as used and a new keypool generated. A new backup must be made when this upgrade is performed.

Additionally, -upgradewallet can be used to upgraded from a non-split HD chain (all keys generated with m/0'/0'/i') to a split HD chain (receiving keys generated with 'm/0'/0'/i' and change keys generated with m'/0'/1'/i'). When this upgrade occurs, all keys already in the keypool will remain in the keypool to be used until all keys from before the upgrade are exhausted. This is to avoid issues with backups and downgrades when some keys may come from the change key keypool. Users can begin using the new split HD chain keypools by using the newkeypool RPC to mark all keys in the keypool as used and begin using a new keypool generated from the split HD chain.

HD Master key rotation

A new RPC, sethdseed, has been introduced which allows users to set a new HD seed or set their own HD seed. This allows for a new HD seed to be used. A new backup must be made when a new HD seed is set.

HD-wallets by default

Due to a backward-incompatible change in the wallet database, wallets created with version 0.17.1 will be rejected by previous versions. Also, version 0.17.1 will only create hierarchical deterministic (HD) wallets. Note that this only applies to new wallets; wallets made with previous versions will not be upgraded to be HD.

Replace-By-Fee by default in GUI

The send screen now uses BIP125 RBF by default, regardless of -walletrbf. There is a checkbox to mark the transaction as final.

The RPC default remains unchanged: to use RBF, launch with -walletrbf=1 or use the replaceable argument for individual transactions.

Wallets directory configuration (-walletdir)

BTG Core now has more flexibility in where the wallets directory can be located. Previously wallet database files were stored at the top level of the bitcoin data directory. The behavior is now:

• For new installations (where the data directory doesn't already exist), wallets will now be stored in a new wallets/ subdirectory inside the data directory by default.
• For existing nodes (where the data directory already exists), wallets will be stored in the data directory root by default. If a wallets/ subdirectory already exists in the data directory root, then wallets will be stored in the wallets/ subdirectory by default.
• The location of the wallets directory can be overridden by specifying a -walletdir=<path> option where <path> can be an absolute path to a directory or directory symlink.

Care should be taken when choosing the wallets directory location, as if it becomes unavailable during operation, funds may be lost.

The -wallet=<path> option now accepts full paths instead of requiring wallets to be located in the -walletdir directory.

Newly created wallet format

If -wallet=<path> is specified with a path that does not exist, it will now create a wallet directory at the specified location (containing a wallet.dat data file, a db.log file, and database/log.?????????? files) instead of just creating a data file at the path and storing log files in the parent directory. This should make backing up wallets more straightforward than before because the specified wallet path can just be directly archived without having to look in the parent directory for transaction log files.

For backwards compatibility, wallet paths that are names of existing data files in the -walletdir directory will continue to be accepted and interpreted the same as before.

Dynamic loading and creation of wallets

Previously, wallets could only be loaded or created at startup, by specifying -wallet parameters on the command line or in the bitcoingold.conf file. It is now possible to load, create and unload wallets dynamically at runtime:

• Existing wallets can be loaded by calling the loadwallet RPC. The wallet can be specified as file/directory basename (which must be located in the walletdir directory), or as an absolute path to a file/directory.
• New wallets can be created (and loaded) by calling the createwallet RPC. The provided name must not match a wallet file in the walletdir directory or the name of a wallet that is currently loaded.
• Loaded wallets can be unloaded by calling the unloadwallet RPC.

This feature is currently only available through the RPC interface.

Coin selection

Partial spend avoidance

When an address is paid multiple times the coins from those separate payments can be spent separately which hurts privacy due to linking otherwise separate addresses. A new -avoidpartialspends flag has been added (default=false). If enabled, the wallet will always spend existing UTXO to the same address together even if it results in higher fees. If someone were to send coins to an address after it was used, those coins will still be included in future coin selections.

Configuration sections for testnet and regtest

It is now possible for a single configuration file to set different options for different networks. This is done by using sections or by prefixing the option with the network, such as:

main.uacomment=bitcoin
test.uacomment=bitcoin-testnet
regtest.uacomment=regtest
[main]
mempoolsize=300
[test]
mempoolsize=100
[regtest]
mempoolsize=20

If the following options are not in a section, they will only apply to mainnet: addnode=, connect=, port=, bind=, rpcport=, rpcbind= and wallet=. The options to choose a network (regtest= and testnet=) must be specified outside of sections.

Changed configuration options

• -includeconf=<file> can be used to include additional configuration files. Only works inside the bitcoingold.conf file, not inside included files or from command-line. Multiple files may be included. Can be disabled from command- line via -noincludeconf. Note that multi-argument commands like -includeconf will override preceding -noincludeconf, i.e.

  noincludeconf=1
  includeconf=relative.conf
  

  as bitcoingold.conf will still include relative.conf.

'label' and 'account' APIs for wallet

A new 'label' API has been introduced for the wallet. This is intended as a replacement for the deprecated 'account' API. The 'account' can continue to be used in V0.17 by starting bgoldd with the '-deprecatedrpc=accounts' argument, and will be fully removed in V0.18.

The label RPC methods mirror the account functionality, with the following functional differences:

• Labels can be set on any address, not just receiving addresses. This functionality was previously only available through the GUI.
• Labels can be deleted by reassigning all addresses using the setlabel RPC method.
• There isn't support for sending transactions from a label, or for determining which label a transaction was sent from.
• Labels do not have a balance.

Here are the changes to RPC methods:

Deprecated Method	New Method	Notes
getaccount	getaddressinfo	getaddressinfo returns a json object with address information instead of just the name of the account as a string.
getaccountaddress	n/a	There is no replacement for getaccountaddress since labels do not have an associated receive address.
getaddressesbyaccount	getaddressesbylabel	getaddressesbylabel returns a json object with the addresses as keys, instead of a list of strings.
getreceivedbyaccount	getreceivedbylabel	no change in behavior
listaccounts	listlabels	listlabels does not return a balance or accept minconf and watchonly arguments.
listreceivedbyaccount	listreceivedbylabel	Both methods return new label fields, along with account fields for backward compatibility.
move	n/a	no replacement
sendfrom	n/a	no replacement
setaccount	setlabel	Both methods now: allow assigning labels to any address, instead of raising an error if the address is not receiving address. delete the previous label associated with an address when the final address using that label is reassigned to a different label, instead of making an implicit getaccountaddress call to ensure the previous label still has a receiving address.

Changed Method	Notes
addmultisigaddress	Renamed account named parameter to label. Still accepts account for backward compatibility if running with '-deprecatedrpc=accounts'.
getnewaddress	Renamed account named parameter to label. Still accepts account for backward compatibility. if running with '-deprecatedrpc=accounts'
listunspent	Returns new label fields. account field will be returned for backward compatibility if running with '-deprecatedrpc=accounts'
sendmany	The account named parameter has been renamed to dummy. If provided, the dummy parameter must be set to the empty string, unless running with the -deprecatedrpc=accounts argument (in which case functionality is unchanged).
listtransactions	Renamed account named parameter to label. Still accepts account for backward compatibility if running with '-deprecatedrpc=accounts'
getbalance	account, minconf and include_watchonly parameters are deprecated, and can only be used if running with '-deprecatedrpc=accounts'

listtransactions label support

When bitcoin is configured with the -deprecatedrpc=accounts setting, specifying a label/account/dummy argument will return both outgoing and incoming transactions. Without the -deprecatedrpc=accounts setting, it will only return incoming transactions (because it used to be possible to create transactions spending from specific accounts, but this is no longer possible with labels).

When -deprecatedrpc=accounts is set, it's possible to pass the empty string "" to list transactions that don't have any label. Without -deprecatedrpc=accounts, passing the empty string is an error because returning only non-labeled transactions is not generally useful behavior and can cause confusion.

BIP 174 Partially Signed Bitcoin Transactions support

BIP 174 PSBT is an interchange format for Bitcoin transactions that are not fully signed yet, together with relevant metadata to help entities work towards signing it. It is intended to simplify workflows where multiple parties need to cooperate to produce a transaction. Examples include hardware wallets, multisig setups, and CoinJoin transactions.

Overall workflow

Overall, the construction of a fully signed Bitcoin transaction goes through the following steps:

• A Creator proposes a particular transaction to be created. He constructs a PSBT that contains certain inputs and outputs, but no additional metadata.
• For each input, an Updater adds information about the UTXOs being spent by the transaction to the PSBT.
• A potentially other Updater adds information about the scripts and public keys involved in each of the inputs (and possibly outputs) of the PSBT.
• Signers inspect the transaction and its metadata to decide whether they agree with the transaction. They can use amount information from the UTXOs to assess the values and fees involved. If they agree, they produce a partial signature for the inputs for which they have relevant key(s).
• A Finalizer is run for each input to convert the partial signatures and possibly script information into a final scriptSig and/or scriptWitness.
• An Extractor produces a valid Bitcoin transaction (in network format) from a PSBT for which all inputs are finalized.

Generally, each of the above (excluding Creator and Extractor) will simply add more and more data to a particular PSBT. In a naive workflow, they all have to operate sequentially, passing the PSBT from one to the next, until the Extractor can convert it to a real transaction. In order to permit parallel operation, Combiners can be employed which merge metadata from different PSBTs for the same unsigned transaction.

The names above in bold are the names of the roles defined in BIP174. They're useful in understanding the underlying steps, but in practice, software and hardware implementations will typically implement multiple roles simultaneously.

RPCs

• converttopsbt (Creator) is a utility RPC that converts an unsigned raw transaction to PSBT format. It ignores existing signatures.
• createpsbt (Creator) is a utility RPC that takes a list of inputs and outputs and converts them to a PSBT with no additional information. It is equivalent to calling createrawtransaction followed by converttopsbt.
• walletcreatefundedpsbt (Creator, Updater) is a wallet RPC that creates a PSBT with the specified inputs and outputs, adds additional inputs and change to it to balance it out, and adds relevant metadata. In particular, for inputs that the wallet knows about (counting towards its normal or watch-only balance), UTXO information will be added. For outputs and inputs with UTXO information present, key and script information will be added which the wallet knows about. It is equivalent to running createrawtransaction, followed by fundrawtransaction, and converttopsbt.
• walletprocesspsbt (Updater, Signer, Finalizer) is a wallet RPC that takes as input a PSBT, adds UTXO, key, and script data to inputs and outputs that miss it, and optionally signs inputs. Where possible it also finalizes the partial signatures.
• finalizepsbt (Finalizer, Extractor) is a utility RPC that finalizes any partial signatures, and if all inputs are finalized, converts the result to a fully signed transaction which can be broadcast with sendrawtransaction.
• combinepsbt (Combiner) is a utility RPC that implements a Combiner. It can be used at any point in the workflow to merge information added to different versions of the same PSBT. In particular it is useful to combine the output of multiple Updaters or Signers.
• decodepsbt is a diagnostic utility RPC which will show all information in a PSBT in human-readable form, as well as compute its eventual fee if known.

Other API changes

• The inactivehdmaster property in the dumpwallet output has been corrected to inactivehdseed

Logging

• The log timestamp format is now ISO 8601 (e.g. "2018-02-28T12:34:56Z").

• When running bgoldd with -debug but without -daemon, logging to stdout is now the default behavior. Setting -printtoconsole=1 no longer implicitly disables logging to debug.log. Instead, logging to file can be explicitly disabled by setting -debuglogfile=0.

Transaction index changes

The transaction index is now built separately from the main node procedure, meaning the -txindex flag can be toggled without a full reindex. If bgoldd is run with -txindex on a node that is already partially or fully synced without one, the transaction index will be built in the background and become available once caught up. When switching from running -txindex to running without the flag, the transaction index database will not be deleted automatically, meaning it could be turned back on at a later time without a full resync.

Miner block size removed

The -blockmaxsize option for miners to limit their blocks' sizes was deprecated in V0.15.1, and has now been removed. Miners should use the -blockmaxweight option if they want to limit the weight of their blocks.

Support for signalling pruned nodes (BIP159)

Pruned nodes can now signal BIP159's NODE_NETWORK_LIMITED using service bits, in preparation for full BIP159 support in later versions. This would allow pruned nodes to serve the most recent blocks. However, the current change does not yet include support for connecting to these pruned peers.

Performance: SHA256 assembly enabled by default

The SHA256 hashing optimizations for architectures supporting SSE4, which lead to ~50% speedups in SHA256 on supported hardware (~5% faster synchronization and block validation), have now been enabled by default. In previous versions they were enabled using the --enable-experimental-asm flag when building, but are now the default and no longer deemed experimental.

RPC changes

New rescanblockchain RPC

A new RPC rescanblockchain has been added to manually invoke a blockchain rescan. The RPC supports start and end-height arguments for the rescan, and can be used in a multiwallet environment to rescan the blockchain at runtime.

New savemempool RPC

A new savemempool RPC has been added which allows the current mempool to be saved to disk at any time to avoid it being lost due to crashes / power loss.

Safe mode disabled by default

Safe mode is now disabled by default and must be manually enabled (with -disablesafemode=0) if you wish to use it. Safe mode is a feature that disables a subset of RPC calls - mostly related to the wallet and sending - automatically in case certain problem conditions with the network are detected. However, developers have come to regard these checks as not reliable enough to act on automatically. Even with safe mode disabled, they will still cause warnings in the warnings field of the getneworkinfo RPC and launch the -alertnotify command.

Renamed script for creating JSON-RPC credentials

The share/rpcuser/rpcuser.py script was renamed to share/rpcauth/rpcauth.py. This script can be used to create rpcauth credentials for a JSON-RPC user.

Validateaddress improvements

The validateaddress RPC output has been extended with a few new fields, and support for segwit addresses (both P2SH and Bech32). Specifically:

• A new field iswitness is True for P2WPKH and P2WSH addresses ("bc1..." addresses), but not for P2SH-wrapped segwit addresses (see below).
• The existing field isscript will now also report True for P2WSH addresses.
• A new field embedded is present for all script addresses where the script is known and matches something that can be interpreted as a known address. This is particularly true for P2SH-P2WPKH and P2SH-P2WSH addresses. The value for embedded includes much of the information validateaddress would report if invoked directly on the embedded address.
• For multisig scripts a new pubkeys field was added that reports the full public keys involved in the script (if known). This is a replacement for the existing addresses field (which reports the same information but encoded as P2PKH addresses), represented in a more useful and less confusing way. The addresses field remains present for non-segwit addresses for backward compatibility.
• For all single-key addresses with known key (even when wrapped in P2SH or P2WSH), the pubkey field will be present. In particular, this means that invoking validateaddress on the output of getnewaddress will always report the pubkey, even when the address type is P2SH-P2WPKH.

Low-level RPC changes

• The new RPC scantxoutset can be used to scan the UTXO set for entries that match certain output descriptors. Refer to the output descriptors reference documentation for more details. This call is similar to listunspent but does not use a wallet, meaning that the wallet can be disabled at compile or run time. This call is experimental, as such, is subject to changes or removal in future releases.

• The createrawtransaction RPC will now accept an array or dictionary (kept for compatibility) for the outputs parameter. This means the order of transaction outputs can be specified by the client.

• The fundrawtransaction RPC will reject the previously deprecated reserveChangeKey option.

• sendmany now shuffles outputs to improve privacy, so any previously expected behavior with regards to output ordering can no longer be relied upon.

• The new RPC testmempoolaccept can be used to test acceptance of a transaction to the mempool without adding it.

• JSON transaction decomposition now includes a weight field which provides the transaction's exact weight. This is included in REST /rest/tx/ and /rest/block/ endpoints when in json mode. This is also included in getblock (with verbosity=2), listsinceblock, listtransactions, and getrawtransaction RPC commands.

• New fees field introduced in getrawmempool, getmempoolancestors, getmempooldescendants and getmempoolentry when verbosity is set to true with sub-fields ancestor, base, modified and descendant denominated in BTC. This new field deprecates previous fee fields, such as fee, modifiedfee, ancestorfee and descendantfee.

• The new RPC getzmqnotifications returns information about active ZMQ notifications.

• When bitcoin is not started with any -wallet=<path> options, the name of the default wallet returned by getwalletinfo and listwallets RPCs is now the empty string "" instead of "wallet.dat". If bitcoin is started with any -wallet=<path> options, there is no change in behavior, and the name of any wallet is just its <path> string.

• Passing an empty string ("") as the address_type parameter to getnewaddress, getrawchangeaddress, addmultisigaddress, fundrawtransaction RPCs is now an error. Previously, this would fall back to using the default address type. It is still possible to pass null or leave the parameter unset to use the default address type.

• Bare multisig outputs to our keys are no longer automatically treated as incoming payments. As this feature was only available for multisig outputs for which you had all private keys in your wallet, there was generally no use for them compared to single-key schemes. Furthermore, no address format for such outputs is defined, and wallet software can't easily send to it. These outputs will no longer show up in listtransactions, listunspent, or contribute to your balance, unless they are explicitly watched (using importaddress or importmulti with hex script argument). signrawtransaction* also still works for them.

• The getwalletinfo RPC method now returns an hdseedid value, which is always the same as the incorrectly-named hdmasterkeyid value. hdmasterkeyid will be removed in V0.18.

• The getaddressinfo RPC method now returns an hdseedid value, which is always the same as the incorrectly-named hdmasterkeyid value. hdmasterkeyid will be removed in V0.18.

• Parts of the validateaddress RPC method have been deprecated and moved to getaddressinfo. Clients must transition to using getaddressinfo to access this information before upgrading to v0.18. The following deprecated fields have moved to getaddressinfo and will only be shown with -deprecatedrpc=validateaddress: ismine, iswatchonly, script, hex, pubkeys, sigsrequired, pubkey, addresses, embedded, iscompressed, account, timestamp, hdkeypath, hdmasterkeyid.

• signrawtransaction is deprecated and will be fully removed in v0.18. To use signrawtransaction in v0.17, restart bgoldd with -deprecatedrpc=signrawtransaction. Projects should transition to using signrawtransactionwithkey and signrawtransactionwithwallet before upgrading to v0.18.

• The deprecated RPC getinfo was removed. It is recommended that the more specific RPCs are used:

  • getblockchaininfo
  • getnetworkinfo
  • getwalletinfo
  • getmininginfo

• The wallet RPC getreceivedbyaddress will return an error if called with an address not in the wallet.

• The wallet RPC addwitnessaddress was deprecated and will be removed in version 0.17, set the address_type argument of getnewaddress, or option -addresstype=[bech32|p2sh-segwit] instead.

• dumpwallet now includes hex-encoded scripts from the wallet in the dumpfile, and importwallet now imports these scripts, but corresponding addresses may not be added correctly or a manual rescan may be required to find relevant transactions.

• The RPC getblockchaininfo now includes an errors field.

• A new blockhash parameter has been added to the getrawtransaction RPC which allows for a raw transaction to be fetched from a specific block if known, even without -txindex enabled.

• The decoderawtransaction and fundrawtransaction RPCs now have optional iswitness parameters to override the heuristic witness checks if necessary.

• The walletpassphrase timeout is now clamped to 2^30 seconds.

• Using addresses with the createmultisig RPC is now deprecated, and will be removed in a later version. Public keys should be used instead.

• Blockchain rescans now no longer lock the wallet for the entire rescan process, so other RPCs can now be used at the same time (although results of balances / transactions may be incorrect or incomplete until the rescan is complete).

• The logging RPC has now been made public rather than hidden.

• An initialblockdownload boolean has been added to the getblockchaininfo RPC to indicate whether the node is currently in IBD or not.

• minrelaytxfee is now included in the output of getmempoolinfo

Other changed command-line options

• -debuglogfile=<file> can be used to specify an alternative debug logging file.
• bgold-cli now has an -stdinrpcpass option to allow the RPC password to be read from standard input.
• The -usehd option has been removed.
• bgold-cli now supports a new -getinfo flag which returns an output like that of the now-removed getinfo RPC.

Testing changes

• The default regtest JSON-RPC port has been changed to 18443 to avoid conflict with testnet's default of 18332.
• Segwit is now always active in regtest mode by default. Thus, if you upgrade a regtest node you will need to either -reindex or use the old rules by adding vbparams=segwit:0:999999999999 to your regtest bitcoingold.conf. Failure to do this will result in a CheckBlockIndex() assertion failure that will look like: Assertion `(pindexFirstNeverProcessed != nullptr) == (pindex->nChainTx == 0)' failed.

Python Support

Support for Python 2 has been discontinued for all test files and tools.

Build: Minimum GCC bumped to 4.8.x

The minimum version of the GCC compiler required to compile BTG Core is now 4.8. No effort will be made to support older versions of GCC. See discussion in issue #11732 for more information. The minimum version for the Clang compiler is still 3.3. Other minimum dependency versions can be found in doc/dependencies.md in the repository.
