Bitcoin ABC 0.19.7
Bitcoin ABC version 0.19.7 is now available from:
This release includes the following features and fixes:
-includeconf=<file>can be used to include additional configuration files. Only works inside the
bitcoin.conffile, 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
-includeconfwill override preceding
-noincludeconf, i.e. noincludeconf=1 includeconf=relative.conf as bitcoin.conf will still include
createrawtransactionRPC will now accept an array or dictionary (kept for compatibility) for the
outputsparameter. This means the order of transaction outputs can be specified by the client.
- The new RPC
testmempoolacceptcan be used to test acceptance of a transaction to the mempool without adding it.
initialblockdownloadboolean has been added to the
getblockchaininfoRPC to indicate whether the node is currently in IBD or not.
- The '-usehd' option has been removed. It is no longer possible to create a non HD wallet.
External wallet files
-wallet=<path> option now accepts full paths instead of requiring wallets
to be located in the -walletdir directory.
Newly created wallet format
-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.
Low-level RPC changes
- When bitcoind is not started with any
-wallet=<path>options, the name of the default wallet returned by
listwalletsRPCs is now the empty string
"wallet.dat". If bitcoind is started with any
-wallet=<path>options, there is no change in behavior, and the name of any wallet is just its
Transaction index changes
The transaction index is now built separately from the main node procedure,
-txindex flag can be toggled without a full reindex. If bitcoind
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
