+### Fixed ###
+- Building with libpathrs for systems that use non-GNU awk, e.g. Debian.
+  (#5196, #5194)
+
 ### Added ###
+- Installation notes for libpathrs. (#5199, #5195)
 - Support for specs.LinuxSeccompFlagWaitKillableRecv. (#5183, #5172)
 - When building runc, `RUNC_BUILDTAGS` make or shell environment variable can

-  prefixed with `-`). (#5171, #xxxx)
+  prefixed with `-`). (#5198, #5171)
+
+### Changed ###
+- runc now requires Go 1.25+ to build. (#5211, #5205)
+- libcontainer now pre-opens container root filesystem and uses the file
+  descriptor (rather than the path) for most operations related to container
+  root during container start. (#5204, #5190)
 
 ### Deprecated ###
 - `EXTRA_BUILDTAGS` make variable is deprecated in favor of `RUNC_BUILDTAGS`
   and will be removed in runc 1.6. (#5171, #5198)
 - `libcontainer/devices` has been deprecated in favour of
   `github.com/moby/sys/devices` (which is a carbon copy of the package). It
-  will be removed in runc 1.6.
+  will be removed in runc 1.6. (#5220, #5142)

+### Fixed ###
+- A regression in runc v1.3.0 which can result in a stuck `runc exec` or
+  `runc run` when the container process runs for a short time. (#5208,
+  #5210, #5216)
+- Mount sources that need to be open on the host are now closed earlier during
+  container start, reducing the total amount of used file descriptors and
+  helping to avoid hitting the open files limit when handling many such mounts.
