+
+### Fixed
+ * Fix a stall issue that would happen if setting `O_CLOEXEC` with
+   `CloseExecFrom` failed (#4647).
+ * `runc` now properly handles joining time namespaces (such as with `runc
+   exec`). Previously we would attempt to set the time offsets when joining,
+   which would fail. (#4635, #4649)
+ * Handle `EINTR` retries correctly for socket-related direct
+   `golang.org/x/sys/unix` system calls. (#4650)
+ * We no longer use `F_SEAL_FUTURE_WRITE` when sealing the runc binary, as it
+   turns out this had some unfortunate bugs in older kernel versions and was
+   never necessary in the first place. (#4651, #4640)
+
+### Removed
+ * Remove `Fexecve` helper from `libcontainer/system`. Runc 1.2.1 removed
+   runc-dmz, but we forgot to remove this helper added only for that. (#4646)
+
+###  Changed
+ * Use Go 1.23 for official builds, run CI with Go 1.24 and drop Ubuntu 20.04
+   from CI. We need to drop Ubuntu 20.04 from CI because Github Actions
+   announced it's already deprecated and it will be discontinued soon. (#4648)
