+### Fixed
+ * Re-add tun/tap devices to built-in allowed devices lists.
+
+   In runc 1.2.0 we removed these devices from the default allow-list (which
+   were added seemingly by accident early in Docker's history) as a precaution
+   in order to try to reduce the attack surface of device inodes available to
+   most containers (#3468). At the time we thought that the vast majority of
+   users using tun/tap would already be specifying what devices they need (such
+   as by using `--device` with Docker/Podman) as opposed to doing the `mknod`
+   manually, and thus there would've been no user-visible change.
+
+   Unfortunately, it seems that this regressed a noticeable number of users
+   (and not all higher-level tools provide easy ways to specify devices to
+   allow) and so this change needed to be reverted. Users that do not need
+   these devices are recommended to explicitly disable them by adding deny
+   rules in their container configuration. (#4555, #4556)
