+---------------
+
+### Prefix DTB file names when deploying
+
+DTB files are now placed in the ${DEPLOY_DIR_IMAGE} with a prefix of
+${PN}-${DISTRO}. During wic imaging, the prefix is removed again, so no changes
+to downstream wks files are needed (i.e. `dtb=my-device-tree.dtb` is not
+affected by this change). Custom imaging plugins need to be adapted to this
+change by removing the prefix from the filename. For that, the variable
+DTB_PREFIX is exported as bitbake var into wic environment.
+
+This fixes errors when building different distros with the same machine,
+whereby previously the following error occured:
+
+do_copy_boot_files: The recipe isar-image-base is trying to install
+files into a shared area when those files already exists. It happens
+when some files have the same names (e.g., dtb files) for different
+distros.
