+## New features and improvements since Qubes 4.0
+
+- Optional qubes-remote-support package now available from repositories
+  (strictly opt-in, no package installed by default; no new ports or network
+  connections open by default; requires explicit connection initiation by the
+  user, then requires sharing a code word with the remote party before a
+  connection can be established; see
+  [#6364](https://github.com/QubesOS/qubes-issues/issues/6364) for more
+  information)
+- Qubes firewall reworked to be more defensive (see
+  [#5540](https://github.com/QubesOS/qubes-issues/issues/5540) for details)
+- Xen upgraded to version 4.14
+- Dom0 operating system upgraded to Fedora 32
+- Default desktop environment upgraded to Xfce 4.14
+- Upgraded default template releases
+- Experimental support for GUI running outside of dom0 (hybrid mode GUI domain
+  without real GPU passthrough; see
+  [#5662](https://github.com/QubesOS/qubes-issues/issues/5662) for details)
+- Experimental support for audio server running outside of dom0 ("Audio domain")
+- sys-firewall and sys-usb are now disposables by default
+- UEFI boot now loads GRUB, which in turn loads Xen, making the boot path
+  similar to legacy boot and allowing the user to modify boot parameters or
+  choose an alternate boot menu entry
+- New qrexec policy format (see
+  [#4370](https://github.com/QubesOS/qubes-issues/issues/4370) for details)
+- qrexec protocol improvements (see
+  [#4909](https://github.com/QubesOS/qubes-issues/issues/4909) for details)

+- New graphical interface for managing testing repository updates
+- New "Cute Qube" icon family (replaces padlock icons)
+- Disposable qube types now use the disposable icon
+- New Template Manager tool for installing, removing, and updating templates
+  (meanwhile, the tool previously known as the "Template Manager," which was
+  for mass template switching, has been integrated into the Qube Manager)
+- The "file" storage driver has been deprecated in Qubes 4.1 and will be
+  removed in Qubes 4.2
+- `property-del` event renamed to `property-reset` to avoid confusion
+- qrexec no longer supports non-executable files in `/etc/qubes-rpc`
+- qrexec components have been reorganized into the core-qrexec repository
+- The `qvm-pool` argument parser has been rewritten and improved
+- Removed the need for the out-of-tree u2mfn kernel module
+- Qrexec services can now run as a socket server
+- Improved template distribution mechanism
+- Now possible to restart qrexec-agent
+- The term "VM" has largely been replaced by "qube"
+- GUI daemon is now configured using `qvm-features` tool,
+  `/etc/qubes/guid.conf` file is no longer used
+- `qvm-run` tool got `--no-shell` option to run a single command without using
+  a shell inside the qube
