+Configuration
+-------------
+
+A new configuration flag `-maxapsfee` has been added, which sets the max allowed
+avoid partial spends (APS) fee. It defaults to 0 (i.e. fee is the same with
+and without APS). Setting it to -1 will disable APS, unless `-avoidpartialspends`
+is set. (#14582)
+
+Wallet
+------
+
+The wallet will now avoid partial spends (APS) by default, if this does not result
+in a difference in fees compared to the non-APS variant. The allowed fee threshold
+can be adjusted using the new `-maxapsfee` configuration option. (#14582)
