+The man:jail[8] command now supports meta and env parameters, which are arbitrary strings associated with a jail. These parameters can be used to tag jails with specific metadata, or to pass information securely to be accessed inside a jail. They can be added at jail creation, or modified later using man:jail[8].

-Jails can now be accessed via jail descriptors in jail_set(2) and jail_get(2), as well as the new jail_attach_jd(2) and jail_remove_jd(2).  They allow manipulation of jails through the file descriptor interface without the race conditions inherent in jail IDs, and can also optionally control jail lifetime.
