Bitcoin ABC 0.22.6 Release Notes

Bitcoin ABC version 0.22.6 is now available from:

This release includes the following features and fixes:

P2P and network changes

This is a follow-up on the removal of BIP61 REJECT message support in Bitcoin ABC version 0.22.5:

Log messages that previously reported the REJECT code when a transaction was not accepted to the mempool now no longer report the REJECT code. The verbal reason for rejection is still reported.

walletprocesspsbt and walletcreatefundedpsbt now include BIP 32 derivation paths by default for public keys if we know them. This can be disabled by setting bip32derivs to false.

A new -asmap configuration option has been added to enable IP-to-ASN mapping for bucketing of the network peers to diversify the network connections. The legacy /16 prefix mapping remains the default. See bitcoind help for more information. This option is experimental and subject to changes or removal in future releases.
Importing blocks upon startup via the bootstrap.dat file no longer occurs by default. The file must now be specified with -loadblock=<file>.

The bitcoin-cli utility used with the -getinfo parameter now returns a headers field with the number of downloaded block headers on the best headers chain (similar to the blocks field that is also returned) and a verificationprogress field that estimates how much of the best block chain has been synced by the local node. The information returned no longer includes the protocolversion, walletversion, and keypoololdest fields.

The minimum supported miniUPnPc version is set to 1.9 (API version 10).
