3This file describes new user-visible features, changes and updates relevant to
4users of binary FreeBSD releases.  Each entry should describe the change in no
5more than several sentences and should reference manual pages where an
6interested user can find more information.  Entries should wrap after 80
7columns.  Each entry should begin with one or more commit IDs on one line,
8specified as a comma separated list and/or range, followed by a colon and a
9newline.  Entries should be separated by a newline.

13r355677:
14	Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
15	(RFC-8276) to the NFS client and server.
16	NFSv4.2 is comprised of several optional features that can be supported
17	in addition to NFSv4.1. This patch adds the following optional features:
18	- posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
19	- posix_fallocate()
20	- intra server file range copying via the copy_file_range(2) syscall
21	--> Avoiding data tranfer over the wire to/from the NFS client.
22	- lseek(SEEK_DATA/SEEK_HOLE)
23	- Extended attribute syscalls for "user" namespace attributes as defined
24	  by RFC-8276.
25
26	For the client, NFSv4.2 is only used if the mount command line option
27	minorversion=2 is specified.
28	For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
29 	and vfs.nfsd.server_max_minorversion4 have been added that allow
30	sysadmins to limit the minor versions of NFSv4 supported by the nfsd
31	server.
32	Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
33	on the server.
34
35r354517:
36	iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
37
38r354269:
39	sqlite3 is updated to sqlite3-3.30.1.
40
41r352668:
42	cron(8) now supports the -n (suppress mail on succesful run) and -q
43	(suppress logging of command execution) options in the crontab format.
44	See the crontab(5) manpage for details.
45
46r352304:
47	ntpd is no longer by default locked in memory. rlimit memlock 32
48	or rlimit memlock 0 can be used to restore this behaviour.
49
50r351522:
51	Add kernel-side support for in-kernel Transport Layer Security
52	(KTLS).  KTLS permits using sendfile(2) over sockets using
53	TLS.
54
55r351397:
56	WPA is updated from 2.8 to 2.9.
57
58r351361:
59	Add probes for lockmgr(9) to the lockstat DTrace provider, add
60	corresponding lockstat(1) events, and document the new probes in
61	dtrace_lockstat.4.
62
63r351356:
64	Intel RST is a new 'feature' that remaps NVMe devices from
65	their normal location to part of the AHCI bar space.  This
66	will eliminate the need to set the BIOS SATA setting from RST
67	to AHCI causing the nvme drive to be erased before FreeBSD
68	will see the nvme drive. FreeBSD will now be able to see the
69	nvme drive now in the default config.
70
71r351201, r351372:
72	Add a vop_stdioctl() call, so that file systems that do not support
73	holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
74	The algorithm appears to be compatible with the POSIX draft and
75	the implementation in Linux for the case of a file system that
76	does not support holes.  Prior to this patch, lseek(2) would reply
77	-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
78	file systems that do not support holes.
79	r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
80	any other cases, such as a ENOTTY return from vn_bmap_seekhole().
81
82r350665:
83	The fuse driver has been renamed to fusefs(5) and been substantially
84	rewritten.  The new driver includes many bug fixes and performance
85	enhancements, as well as the following user-visible features:
86	* Optional kernel-side permissions checks (-o default_permissions)
87	* mknod(2), socket(2), and pipe(2) support
88	* server side locking with fcntl(2)
89	* FUSE operations are now interruptible when mounted with -o intr
90	* server side handling of UTIME_NOW during utimensat(2)
91	* mount options may be updated with "mount -u"
92	* fusefs file system may now be exported over NFS
93	* RLIMIT_FSIZE support
94	* support for fuse file systems using protocols as old as 7.4
95
96	FUSE file system developers should also take note of the following new
97	features:
98	* The protocol level has been raised from 7.8 to 7.23
99	* kqueue support on /dev/fuse
100	* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
101
102r350471:
103	gnop(8) can now configure a delay to be applied to read and write
104	request delays.  See the -d, -q and -x parameters.
105
106r350315, r350316:
107	Adds a Linux compatible copy_file_range(2) syscall.
108
109r350307:
110	libcap_random(3) has been removed.  Applications can use native
111	APIs to get random data in capability mode.
112
113r349529,r349530:
114	Add support for using unmapped mbufs with sendfile(2).
115
116r349352:
117	nand(4) and related components have been removed.
118
119r349349:
120	The UEFI loader now supports HTTP boot.
121
122r349335:
123	bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
124	guests to play to and record audio data from the host.
125
126r349286:
127	swapon(8) can now erase a swap device immediately before enabling it,
128	similar to newfs(8)'s -E option.  This behaviour can be specified by
129	adding -E to swapon(8)'s command-line parameters, or by adding the
130	"trimonce" option to a swap device's /etc/fstab entry.
131
132r347908-r347923:
133	The following network drivers have been removed: bm(4), cs(4), de(4),
134	ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
135	vx(4), wb(4), xe(4).
