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.

12
13r351361:
14	Add probes for lockmgr(9) to the lockstat DTrace provider, add
15	corresponding lockstat(1) events, and document the new probes in
16	dtrace_lockstat.4.
17
18r351356:
19	Intel RST is a new 'feature' that remaps NVMe devices from
20	their normal location to part of the AHCI bar space.  This
21	will eliminate the need to set the BIOS SATA setting from RST
22	to AHCI causing the nvme drive to be erased before FreeBSD
23	will see the nvme drive. FreeBSD will now be able to see the
24	nvme drive now in the default config.
25
26r351201, r351372:
27	Add a vop_stdioctl() call, so that file systems that do not support
28	holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
29	The algorithm appears to be compatible with the POSIX draft and
30	the implementation in Linux for the case of a file system that
31	does not support holes.  Prior to this patch, lseek(2) would reply
32	-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
33	file systems that do not support holes.
34	r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
35	any other cases, such as a ENOTTY return from vn_bmap_seekhole().
36
37r350665:
38	The fuse driver has been renamed to fusefs(5) and been substantially
39	rewritten.  The new driver includes many bug fixes and performance
40	enhancements, as well as the following user-visible features:
41	* Optional kernel-side permissions checks (-o default_permissions)
42	* mknod(2), socket(2), and pipe(2) support
43	* server side locking with fcntl(2)
44	* FUSE operations are now interruptible when mounted with -o intr
45	* server side handling of UTIME_NOW during utimensat(2)
46	* mount options may be updated with "mount -u"
47	* fusefs file system may now be exported over NFS
48	* RLIMIT_FSIZE support
49	* support for fuse file systems using protocols as old as 7.4
50
51	FUSE file system developers should also take note of the following new
52	features:
53	* The protocol level has been raised from 7.8 to 7.23
54	* kqueue support on /dev/fuse
55	* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
56
57r350471:
58	gnop(8) can now configure a delay to be applied to read and write
59	request delays.  See the -d, -q and -x parameters.
60
61r350315, r350316:
62	Adds a Linux compatible copy_file_range(2) syscall.
63
64r350307:
65	libcap_random(3) has been removed.  Applications can use native
66	APIs to get random data in capability mode.
67
68r349352:
69	nand(4) and related components have been removed.
70
71r349349:
72	The UEFI loader now supports HTTP boot.
73
74r349335:
75	bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
76	guests to play to and record audio data from the host.
77
78r349286:
79	swapon(8) can now erase a swap device immediately before enabling it,
80	similar to newfs(8)'s -E option.  This behaviour can be specified by
81	adding -E to swapon(8)'s command-line parameters, or by adding the
82	"trimonce" option to a swap device's /etc/fstab entry.
83
84r347908-r347923:
85	The following network drivers have been removed: bm(4), cs(4), de(4),
86	ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
87	vx(4), wb(4), xe(4).
