The local stream (AF_UNIX/SOCK_STREAM) and sequenced packet stream (AF_UNIX/SOCK_SEQPACKET) sockets have been improved for better bulk transfer and round trip times.
The SOCK_SEQPACKET socket has been brought to the specification and now behaves as a true stream socket, while in previous FreeBSD releases it could exhibit features of
a datagram socket. Applications that were using SOCK_SEQPACKET incorrectly and relied on old implementation bugs may need to be adjusted.

The effective group ID is now stored in the new `cr_gid` field of `struct cred` and has been removed as the first element of `cr_groups[]`, which now only contains the supplementary groups.
All downstream and out-of-tree modules using `cr_groups[0]` must be fixed to use `cr_gid` instead, and surrounding code that loops on `cr_groups[]` elements excluding `cr_groups[0]`, i.e., that intends to act on supplementary groups only, also needs to be adjusted as now supplementary groups start at `&cr_groups[0]` instead of `&cr_groups[1]`.
Code that needs to be portable to both 15.0 and earlier versions can use `cr_gid`, which existed also previously as a macro, and can test the truth value of `&cr_groups[0] != &cr_gid` to know how to browse the supplementary groups adequately.
