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.

11Changes to this file should not be MFCed.
12
13r357627:
14	remove elf2aout.
15
16r357560-r357565:
17	init(8), service(8), and cron(8) will now adopt user/class environment
18	variables (excluding PATH, by default, which will be overwritten) by
19	default.  Notably, environment variables for all cron jobs and rc
20	services can now be set via login.conf(5).
21
22r357455:
23	sparc64 has been removed from FreeBSD.
24
25r355677:
26	Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
27	(RFC-8276) to the NFS client and server.
28	NFSv4.2 is comprised of several optional features that can be supported
29	in addition to NFSv4.1. This patch adds the following optional features:
30	- posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
31	- posix_fallocate()
32	- intra server file range copying via the copy_file_range(2) syscall
33	--> Avoiding data tranfer over the wire to/from the NFS client.
34	- lseek(SEEK_DATA/SEEK_HOLE)
35	- Extended attribute syscalls for "user" namespace attributes as defined
36	  by RFC-8276.
37
38	For the client, NFSv4.2 is only used if the mount command line option
39	minorversion=2 is specified.
40	For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
41 	and vfs.nfsd.server_max_minorversion4 have been added that allow
42	sysadmins to limit the minor versions of NFSv4 supported by the nfsd
43	server.
44	Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
45	on the server.
46
47r356263:
48	armv5 support has been removed from FreeBSD.
49
50r354517:
51	iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
52
53r354269:
54	sqlite3 is updated to sqlite3-3.30.1.
55
56r352668:
57	cron(8) now supports the -n (suppress mail on succesful run) and -q
58	(suppress logging of command execution) options in the crontab format.
59	See the crontab(5) manpage for details.
60
61r352304:
62	ntpd is no longer by default locked in memory. rlimit memlock 32
63	or rlimit memlock 0 can be used to restore this behaviour.
64
65r351522:
66	Add kernel-side support for in-kernel Transport Layer Security
67	(KTLS).  KTLS permits using sendfile(2) over sockets using
68	TLS.
69
70r351397:
71	WPA is updated from 2.8 to 2.9.
72
73r351361:
74	Add probes for lockmgr(9) to the lockstat DTrace provider, add
75	corresponding lockstat(1) events, and document the new probes in
76	dtrace_lockstat.4.
77
78r351356:
79	Intel RST is a new 'feature' that remaps NVMe devices from
80	their normal location to part of the AHCI bar space.  This
81	will eliminate the need to set the BIOS SATA setting from RST
82	to AHCI causing the nvme drive to be erased before FreeBSD
83	will see the nvme drive. FreeBSD will now be able to see the
84	nvme drive now in the default config.
85
86r351201, r351372:
87	Add a vop_stdioctl() call, so that file systems that do not support
88	holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
89	The algorithm appears to be compatible with the POSIX draft and
90	the implementation in Linux for the case of a file system that
91	does not support holes.  Prior to this patch, lseek(2) would reply
92	-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
93	file systems that do not support holes.
94	r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
95	any other cases, such as a ENOTTY return from vn_bmap_seekhole().
96
97r350665:
98	The fuse driver has been renamed to fusefs(5) and been substantially
99	rewritten.  The new driver includes many bug fixes and performance
100	enhancements, as well as the following user-visible features:
101	* Optional kernel-side permissions checks (-o default_permissions)
102	* mknod(2), socket(2), and pipe(2) support
103	* server side locking with fcntl(2)
104	* FUSE operations are now interruptible when mounted with -o intr
105	* server side handling of UTIME_NOW during utimensat(2)
106	* mount options may be updated with "mount -u"
107	* fusefs file system may now be exported over NFS
108	* RLIMIT_FSIZE support
109	* support for fuse file systems using protocols as old as 7.4
110
111	FUSE file system developers should also take note of the following new
112	features:
113	* The protocol level has been raised from 7.8 to 7.23
114	* kqueue support on /dev/fuse
115	* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
116
117r350471:
118	gnop(8) can now configure a delay to be applied to read and write
119	request delays.  See the -d, -q and -x parameters.
120
121r350315, r350316:
122	Adds a Linux compatible copy_file_range(2) syscall.
123
124r350307:
125	libcap_random(3) has been removed.  Applications can use native
126	APIs to get random data in capability mode.
127
128r349529,r349530:
129	Add support for using unmapped mbufs with sendfile(2).
130
131r349352:
132	nand(4) and related components have been removed.
133
134r349349:
135	The UEFI loader now supports HTTP boot.
136
137r349335:
138	bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
139	guests to play to and record audio data from the host.
140
141r349286:
142	swapon(8) can now erase a swap device immediately before enabling it,
143	similar to newfs(8)'s -E option.  This behaviour can be specified by
144	adding -E to swapon(8)'s command-line parameters, or by adding the
145	"trimonce" option to a swap device's /etc/fstab entry.
146
147r347908-r347923:
148	The following network drivers have been removed: bm(4), cs(4), de(4),
149	ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
150	vx(4), wb(4), xe(4).
