 This release includes the following features and fixes:
+- New `fees` field introduced in `getrawmempool`, `getmempoolancestors`, `getmempooldescendants` and `getmempoolentry` when verbosity is set to `true` with sub-fields `ancestor`, `base`, `modified` and `descendent` denominated in BCH. This new field deprecates previous fee fields, such as `fee`, `modifiedfee`, `ancestorfee` and `descendentfee`.
