+:Summary: Replace VNC with RDP (#2231339)
+
+:Description:
+    As part of the X11 dependencies removals, Anaconda also drops VNC. As a replacement
+    RDP (Remote Desktop Protocol) is implemented.
+
+    What has changed:
+    - Adding new kernel boot arguments: ``inst.rdp``, ``inst.rdp.username``, ``inst.rdp.password``.
+    - Drop existing kernel boot argument: ``inst.vnc``, ``inst.vncpassword``, ``inst.vncconnect``.
+    - Drop the existing ``vnc`` kickstart command.

+:Type: GUI
+:Summary: Migrate Anaconda to Wayland application (#2231339)
+
+:Description:
+    This change enables Anaconda to run natively on Wayland. Previously, Anaconda operated as an
+    Xorg application or relied on XWayland for support.
+
+    By implementing this update, we can eliminate dependencies on X11 and embrace newer, more
+    secure technologies.
