+
+### Deprecated ###
+- `libcontainer/configs.MPOL_*` constants added in runc [1.4.0][]. (#5110,
+  #5055)
+
+### Added ###
+- Preliminary `loong64` support. (#5062, #4938)
+
+### Fixed ###
+- libct: fix panic in `initSystemdProps` when processing certain systemd
+  properties in the OCI spec. (#5161, #5133)
+- libct: fix several file descriptor leaks on error paths. (#5168, #5009)
+- Remove unnecessary `crypto/tls` dependency by open-coding the systemd socket
+  activation logic, allowing us to more easily avoid false positive CVE
+  warnings. (#5093, #5057)
+- Remove legacy `os.Is*` error usage, improving error type detection to make
+  our error fallback paths more robust. (#5162, #5061)
+- Go 1.26 has started enforcing a restriction of `os/exec.Cmd` which caused
+  issues with our usage of `CLONE_INTO_CGROUP` (on newer kernels). This has now
+  been resolved. (#5116, #5091)
+- Recursive `atime`-related mount flags (`rrelatime` et al.) are now applied
+  properly. (#5114, #5098)
+- Fix a regression in `runc exec` due to `CLONE_INTO_CGROUP` in the
+  (inadvisable) scenario where a container is configured without cgroup
+  namespaces and with `/sys/fs/cgroup` mounted `rw`. (#5117, #5101)
+- On machines with more than 1024 CPU cores, our logic for resetting the CPU
+  affinity will now correctly reset the affinity onto _all_ available cores
+  (not just the first 1024). (#5149, #5025)
+- PR #4757 caused a regression that resulted in spurious `cannot start a
+  container that has stopped` errors when running `runc create` and has thus
+  been reverted. (#5157, #5153, #5151, #4645, #4757)
+
+### Changed ###
 - Previously we made an attempt to make our `runc.armhf` release binaries work
   with ARMv6 (which would allow runc to work on the original Raspberry Pi).
   Unfortunately, this has effectively always been broken (because we
   cross-compile `libseccomp` within a Debian container and statically link to
   it) and so we are now officially matching [the Debian definition of `armhf`][debian-armhf]
