+### Changed
+ - Quarantining of passed-through PCI devices no longer defaults to directing 
I/O to a scratch
+   page, matching original post-XSA-302 behavior (albeit the change was also 
backported, first
+   appearing in 4.12.2 and 4.11.4). Prior (4.13...4.15-like) behavior can be 
arranged for
+   either by enabling the IOMMU_QUARANTINE_SCRATCH_PAGE setting at build 
(configuration) time
+   or by passing "iommu=quarantine=scratch-page" on the hypervisor command 
  ## [4.15.0 
 - TBD
### Added / support upgraded
