 ## [Unreleased]
+### Changed
+- `umoci` now outputs configurations that are compliant with [`v1.0.0-rc5` of
+  the OCI runtime-spec][rspec-v1.0.0-rc5]. This means that now you can use runc
+  v1.0.0-rc3 with `umoci` (and rootless containers should work out of the box
+  if you use a development build of runc). openSUSE/umoci#114
+- `umoci unpack` no longer adds a dummy linux.seccomp entry, and instead just
+  sets it to null. openSUSE/umoci#114
