- Calls to
getblocktemplatewill fail if the segwit rule is not specified. Calling
getblocktemplatewithout segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
Configuration option changes
- A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are
- Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the “high water mark”) before dropping additional messages. The default value is 1,000, the same as was used for previous releases. See the ZMQ documentation for details.
rpcallowipoption can no longer be used to automatically listen on all network interfaces. Instead, the
rpcbindparameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g.
docker run [...] -p 127.0.0.1:9332:9332(this is an extra
:9332over the normal Docker port specification).
rpcpasswordoption now causes a startup error if the password set in the configuration file contains a hash character (#), as it’s ambiguous whether the hash character is meant for the password or as a comment.
whitelistforcerelayoption is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers. Users can still explicitly enable this behavior with the command line option (and may want to consider contacting the Litecoin Core project to let us know about their use-case, as this feature could be deprecated in the future).
When creating a transaction with a fee above
-maxtxfee (default 0.1 LTC), the RPC commands
fundrawtransaction will now fail instead of rounding down the fee. Beware that the
feeRate argument is specified in LTC per kilobyte, not litoshi per byte.
We are pleased to release Litecoin Core 0.18.1. This is a new major version release, including new features, various bugfixes and performance improvements, as well as updated translations. It is recommended for all users to upgrade to this version.
