+draft: false
+contributors: [Cloud Hypervisor Team]
+---
+This release has been tracked in [v47.0 group](https://github.com/orgs/cloud-hypervisor/projects/6/views/4?filterQuery=release%3A%22Release+47%22) of our [roadmap project](https://github.com/orgs/cloud-hypervisor/projects/6/).
+
+Block Device Error Reporting to the Guest
+-----------------------------------------
+
+Instead of exiting on I/O errors, the `virtio-block` device now reports
+errors to the guest using `VIRTIO_BLK_S_IOERR`. It improves the user
+experience particularly when the guest rootfs is not backed by the
+affected block device. (#7107)
+
+Nice Error Messages on Exit
+---------------------------
+
+We now have the chain of errors being reported and printed nicely, when
+Cloud Hypervisor or ch-remote exits on errors. (#7066)
+
+Alphabetically Sorted CLI Options for ch-remote
+-----------------------------------------------
+
+To improve readability, ch-remote now prints help information in
+alphabetical order. (#7130)
+
+Notable Bug Fixes
+-----------------
+
+* Error out early when block device serial is too long (#7124)
+* Fix partial commands being discarded for `virtio-vsock` (#7195)
+* Disable the broken interrupt support for the `rtc_pl031` device to
+  prevent spurious guest interrupts (#7199)
+
+Deprecations
+------------
+
+* A default IP (`192.168.249.1`) and mask (`255.255.255.0`) are
+ currently assigned  to the `virtio-net` device if no value is specified
+ by users. Such behavior is now deprecated.  Users of this behavior will
+ receive a warning message and should make adjustments. The behavior
+ will be removed in two release cycles (v49.0).
