+### Deprecated ###
+- The `libcontainer/configs.Mount.Relabel` configuration field (used to relabel
+  mounts with the `z` and `Z` "pseudo" mount options) was never accessible
+  outside of the libcontainer API, and in practice the relabel logic has always
+  lived in higher level runtimes. It has been made into a no-op and the field
+  will be removed entirely in runc 1.7. (#5152, #5160)
 
 ### Removed ###
 - The `memfd-bind` helper binary has been removed, as it has never been
   particularly useful and was completely obsoleted by the changes to
   `/proc/self/exe` sealing we introduced in runc [1.2.0][]. (#5141)
 
+### Added ###
+- User-namespaced containers can now configure `user.*` sysctls. (#4889)
+- Intel RDT: the RDT subdirectory is now only removed if runc created it,

   need to adjust their packaging accordingly. runc can still be built without
   libpathrs (by building without the `libpathrs` build tag), but we currently
   plan to make runc 1.6 *require* libpathrs. (#5103)
+- `runc exec` will now request systemd to move the `exec` process into the
+  container cgroup, making the procedure more rootless-friendly. (#4822)
+- seccomp: minor documentation updates. (#4902)
+- Errors from `runc init` have historically been quite painful to understand
+  and debug, we have made several improvements to make them more comprehensive

+- Update spec conformance documentation for OCI runtime-spec v1.3.0. (#4948,
+  #5150)
+- Our release archives now have the name `runc-$version.tar.xz` to make distro
+  packaging a little easier by matching the filename to the top-level directory
