1Release notes for FreeBSD 13.0.

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