 # Bitcoin ABC 0.22.6 Release Notes
 
 Bitcoin ABC version 0.22.6 is now available from:
 
   <https://download.bitcoinabc.org/0.22.6/>
 
 This release includes the following features and fixes:
 
 P2P and network changes
 -----------------------
 
 #### Removal of reject network messages from Bitcoin ABC (BIP61)
 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.
 
 Updated RPCs
 ------------
 
 - `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`.
+
+New settings
+------------
+
+- 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.
