+
+ * fix #5409: backup: fix copy-before-write timeout
+
+ * backup: improve error when copy-before-write fails for fleecing
+
+ * fix forwards and backwards migration with VirtIO-GPU display
+
+ * fix a regression in pflash device introduced in 8.2
+
+ * revert a commit for VirtIO PCI devices that turned out to cause more
+ potential security issues than what it fixed
+
+ * move compatibility flags for a new VirtIO-net feature to the correct
+ machine type. The feature was introduced in QEMU 8.2, but the
+ compatibility flags got added to machine version 8.0 instead of 8.1. This
+ breaks backwards migration with machine version 8.1 from a 8.2/9.0 binary
+ to an 8.1 binary, in cases where the guest kernel enables the feature
+ (e.g. Ubuntu 23.10).
+ While that breaks migration with machine version 8.1 from an unpatched to
+ a patched binary, Proxmox VE only ever had 8.2 on the test repository and
+ 9.0 not yet in any public repository.
