 # New Features
 
+* Add support for [archiving channel backup](https://github.com/lightningnetwork/lnd/pull/9232)
+ in a designated folder which allows for easy referencing in the future. A new 
+ config is added `disable-backup-archive`, with default set to false, to 
+ determine if previous channel backups should be archived or not.
+
+## Protocol Updates
+
+* `lnd` now [supports the new RBF cooperative close
+flow](https://github.com/lightningnetwork/lnd/pull/9610). Unlike the old flow,
+this version now uses RBF to enable either side to increase their fee rate using
+their _own_ channel funds. This removes the old "negotiation" logic that could
+fail, with a version where either side can increase the fee on their coop close
+transaction using their channel balance. 
+
+This new feature can be activated with a new config flag:
+`--protocol.rbf-coop-close`.
+
+With this new co-op close type, users can issue multiple `lncli closechannnel`
+commands with increasing fee rates to use RBF to bump an existing signed co-op
+close transaction.
