+GUI changes
+-----------
+
+- Dash-Qt can now register and maintain regular masternodes and EvoNodes from
+  the Masternodes tab. The registration wizard supports wallet-funded,
+  wallet-owned, and externally held collateral, while row actions provide
+  Update Service, Update Registrar, and Revoke workflows. Generated operator
+  keys are shown and confirmed before registration; wallet-seed-derived
+  operator keys are not required. (#7618)
