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.

13r357560-r357565:
14	init(8), service(8), and cron(8) will now adopt user/class environment
15	variables (excluding PATH, by default, which will be overwritten) by
16	default.  Notably, environment variables for all cron jobs and rc
17	services can now be set via login.conf(5).
18
19r355677:
20	Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
21	(RFC-8276) to the NFS client and server.
22	NFSv4.2 is comprised of several optional features that can be supported
23	in addition to NFSv4.1. This patch adds the following optional features:
24	- posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
25	- posix_fallocate()
26	- intra server file range copying via the copy_file_range(2) syscall
27	--> Avoiding data tranfer over the wire to/from the NFS client.
28	- lseek(SEEK_DATA/SEEK_HOLE)
29	- Extended attribute syscalls for "user" namespace attributes as defined
30	  by RFC-8276.
31
32	For the client, NFSv4.2 is only used if the mount command line option
33	minorversion=2 is specified.
34	For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
35 	and vfs.nfsd.server_max_minorversion4 have been added that allow
36	sysadmins to limit the minor versions of NFSv4 supported by the nfsd
37	server.
38	Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
39	on the server.
40
41r354517:
42	iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
43
44r354269:
45	sqlite3 is updated to sqlite3-3.30.1.
46
47r352668:
48	cron(8) now supports the -n (suppress mail on succesful run) and -q
49	(suppress logging of command execution) options in the crontab format.
50	See the crontab(5) manpage for details.
51
52r352304:
53	ntpd is no longer by default locked in memory. rlimit memlock 32
54	or rlimit memlock 0 can be used to restore this behaviour.
55
56r351522:
57	Add kernel-side support for in-kernel Transport Layer Security
58	(KTLS).  KTLS permits using sendfile(2) over sockets using
59	TLS.
60
61r351397:
62	WPA is updated from 2.8 to 2.9.
63
64r351361:
65	Add probes for lockmgr(9) to the lockstat DTrace provider, add
66	corresponding lockstat(1) events, and document the new probes in
67	dtrace_lockstat.4.
68
69r351356:
70	Intel RST is a new 'feature' that remaps NVMe devices from
71	their normal location to part of the AHCI bar space.  This
72	will eliminate the need to set the BIOS SATA setting from RST
73	to AHCI causing the nvme drive to be erased before FreeBSD
74	will see the nvme drive. FreeBSD will now be able to see the
75	nvme drive now in the default config.
76
77r351201, r351372:
78	Add a vop_stdioctl() call, so that file systems that do not support
79	holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
80	The algorithm appears to be compatible with the POSIX draft and
81	the implementation in Linux for the case of a file system that
82	does not support holes.  Prior to this patch, lseek(2) would reply
83	-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
84	file systems that do not support holes.
85	r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
86	any other cases, such as a ENOTTY return from vn_bmap_seekhole().
87
88r350665:
89	The fuse driver has been renamed to fusefs(5) and been substantially
90	rewritten.  The new driver includes many bug fixes and performance
91	enhancements, as well as the following user-visible features:
92	* Optional kernel-side permissions checks (-o default_permissions)
93	* mknod(2), socket(2), and pipe(2) support
94	* server side locking with fcntl(2)
95	* FUSE operations are now interruptible when mounted with -o intr
96	* server side handling of UTIME_NOW during utimensat(2)
97	* mount options may be updated with "mount -u"
98	* fusefs file system may now be exported over NFS
99	* RLIMIT_FSIZE support
100	* support for fuse file systems using protocols as old as 7.4
101
102	FUSE file system developers should also take note of the following new
103	features:
104	* The protocol level has been raised from 7.8 to 7.23
105	* kqueue support on /dev/fuse
106	* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
107
108r350471:
109	gnop(8) can now configure a delay to be applied to read and write
110	request delays.  See the -d, -q and -x parameters.
111
112r350315, r350316:
113	Adds a Linux compatible copy_file_range(2) syscall.
114
115r350307:
116	libcap_random(3) has been removed.  Applications can use native
117	APIs to get random data in capability mode.
118
119r349529,r349530:
120	Add support for using unmapped mbufs with sendfile(2).
121
122r349352:
123	nand(4) and related components have been removed.
124
125r349349:
126	The UEFI loader now supports HTTP boot.
127
128r349335:
129	bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
130	guests to play to and record audio data from the host.
131
132r349286:
133	swapon(8) can now erase a swap device immediately before enabling it,
134	similar to newfs(8)'s -E option.  This behaviour can be specified by
135	adding -E to swapon(8)'s command-line parameters, or by adding the
136	"trimonce" option to a swap device's /etc/fstab entry.
137
138r347908-r347923:
139	The following network drivers have been removed: bm(4), cs(4), de(4),
140	ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
141	vx(4), wb(4), xe(4).
