 Notable changes
 ===============
 
-### Mempool & Policy
-
- The minimum block feerate (`-blockmintxfee`) has been changed to 1 satoshi per kvB. It can still be changed using the
-configuration option.
-
-- The default minimum relay feerate (`-minrelaytxfee`) and incremental relay feerate (`-incrementalrelayfee`) have been
-changed to 100 satoshis per kvB. They can still be changed using their respective configuration options, but it is
-recommended to change both together if you decide to do so.
-  - Other minimum feerates (e.g. the dust feerate, the minimum returned by the fee estimator, and all feerates used by
-  the wallet) remain unchanged. The mempool minimum feerate still changes in response to high volume.
-  - Note that unless these lower defaults are widely adopted across the network, transactions created with lower fee
-  rates are not guaranteed to propagate or confirm. The wallet feerates remain unchanged; `-mintxfee` must be changed
-  before attempting to create transactions with lower feerates using the wallet.
