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
13r362158, r362163:
14	struct export_args has changed so that the "user" specified for
15	the -maproot and -mapall exports(5) options may be in more than
16	16 groups.
17
18r361884:
19	sed(1) has learned about hex escapes (e.g. \x27) and will now do the
20	right thing with them, removing the need for printf magic or obnoxious
21	escaping in many scenarios.
22
23r361238, r361798, r361799:
24	ZFS will now unconditionally reject read(2) of a directory with EISDIR.
25	Additionally, read(2) of a directory is now rejected with EISDIR by
26	default and may be re-enabled for non-ZFS filesystems that allow it with
27	the sysctl(8) MIB 'security.bsd.allow_read_dir'.
28
29	Aliases for grep to default to '-d skip' may be desired if commonly
30	non-recursively grepping a list that includes directories and the
31	possibility of EISDIR errors in stderr is not tolerable.  Example
32	aliases, commented out, have been installed in /root/.cshrc and
33	/root/.shrc.
34
35r361066:
36	Add exec.prepare and exec.release hooks for jail(8) and jail.conf(5).
37	exec.prepare runs before mounts, so can be used to populate new jails.
38	exec.release runs after unmounts, so can be used to remove ephemeral
39	jails.

41r360920,r360923,r360924,r360927,r360928,r360931,r360933,r360936:
42	Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
43	MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
44	the kernel open cryptographic framework (OCF).
45
46r360562:
47	Remove support for ARC4, Blowfish, Cast, DES, Triple DES,
48	MD5-HMAC, and Skipjack algorithms from /dev/crypto.
49
50r360557:
51	Remove support for DES, Triple DES, Blowfish, Cast, and
52	Camellia ciphers from IPsec(4).  Remove support for MD5-HMAC,
53	Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
54
55r359945:
56	Remove support for Triple DES, Blowfish, and MD5 HMAC from
57	geli(4).
58
59r359786-r359787:
60	Remove support for DES, Triple DES, and RC4 from in-kernel GSS
61	authentication.
62
63r357627:
64	remove elf2aout.
65
66r357560-r357565:
67	init(8), service(8), and cron(8) will now adopt user/class environment
68	variables (excluding PATH, by default, which will be overwritten) by
69	default.  Notably, environment variables for all cron jobs and rc
70	services can now be set via login.conf(5).
71
72r357455:
73	sparc64 has been removed from FreeBSD.
74
75r355677:
76	Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
77	(RFC-8276) to the NFS client and server.
78	NFSv4.2 is comprised of several optional features that can be supported
79	in addition to NFSv4.1. This patch adds the following optional features:
80	- posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
81	- posix_fallocate()
82	- intra server file range copying via the copy_file_range(2) syscall
83	--> Avoiding data tranfer over the wire to/from the NFS client.
84	- lseek(SEEK_DATA/SEEK_HOLE)
85	- Extended attribute syscalls for "user" namespace attributes as defined
86	  by RFC-8276.
87
88	For the client, NFSv4.2 is only used if the mount command line option
89	minorversion=2 is specified.
90	For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
91 	and vfs.nfsd.server_max_minorversion4 have been added that allow
92	sysadmins to limit the minor versions of NFSv4 supported by the nfsd
93	server.
94	Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
95	on the server.
96
97r356263:
98	armv5 support has been removed from FreeBSD.
99
100r354517:
101	iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
102
103r354269:
104	sqlite3 is updated to sqlite3-3.30.1.
105
106r352668:
107	cron(8) now supports the -n (suppress mail on succesful run) and -q
108	(suppress logging of command execution) options in the crontab format.
109	See the crontab(5) manpage for details.
110
111r352304:
112	ntpd is no longer by default locked in memory. rlimit memlock 32
113	or rlimit memlock 0 can be used to restore this behaviour.
114
115r351770,r352920,r352922,r352923:
116	dd(1) now supports conv=fsync, conv=fdatasync, oflag=fsync, oflag=sync,
117	and iflag=fullblock flags, compatible with illumos and GNU.
118
119r351522:
120	Add kernel-side support for in-kernel Transport Layer Security
121	(KTLS).  KTLS permits using sendfile(2) over sockets using
122	TLS.
123
124r351397:
125	WPA is updated from 2.8 to 2.9.
126
127r351361:
128	Add probes for lockmgr(9) to the lockstat DTrace provider, add
129	corresponding lockstat(1) events, and document the new probes in
130	dtrace_lockstat.4.
131
132r351356:
133	Intel RST is a new 'feature' that remaps NVMe devices from
134	their normal location to part of the AHCI bar space.  This
135	will eliminate the need to set the BIOS SATA setting from RST
136	to AHCI causing the nvme drive to be erased before FreeBSD
137	will see the nvme drive. FreeBSD will now be able to see the
138	nvme drive now in the default config.
139
140r351201, r351372:
141	Add a vop_stdioctl() call, so that file systems that do not support
142	holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
143	The algorithm appears to be compatible with the POSIX draft and
144	the implementation in Linux for the case of a file system that
145	does not support holes.  Prior to this patch, lseek(2) would reply
146	-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
147	file systems that do not support holes.
148	r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
149	any other cases, such as a ENOTTY return from vn_bmap_seekhole().
150
151r350665:
152	The fuse driver has been renamed to fusefs(5) and been substantially
153	rewritten.  The new driver includes many bug fixes and performance
154	enhancements, as well as the following user-visible features:
155	* Optional kernel-side permissions checks (-o default_permissions)
156	* mknod(2), socket(2), and pipe(2) support
157	* server side locking with fcntl(2)
158	* FUSE operations are now interruptible when mounted with -o intr
159	* server side handling of UTIME_NOW during utimensat(2)
160	* mount options may be updated with "mount -u"
161	* fusefs file system may now be exported over NFS
162	* RLIMIT_FSIZE support
163	* support for fuse file systems using protocols as old as 7.4
164
165	FUSE file system developers should also take note of the following new
166	features:
167	* The protocol level has been raised from 7.8 to 7.23
168	* kqueue support on /dev/fuse
169	* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
170
171r350471:
172	gnop(8) can now configure a delay to be applied to read and write
173	request delays.  See the -d, -q and -x parameters.
174
175r350315, r350316:
176	Adds a Linux compatible copy_file_range(2) syscall.
177
178r350307:
179	libcap_random(3) has been removed.  Applications can use native
180	APIs to get random data in capability mode.
181
182r349529,r349530:
183	Add support for using unmapped mbufs with sendfile(2).
184
185r349352:
186	nand(4) and related components have been removed.
187
188r349349:
189	The UEFI loader now supports HTTP boot.
190
191r349335:
192	bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
193	guests to play to and record audio data from the host.
194
195r349286:
196	swapon(8) can now erase a swap device immediately before enabling it,
197	similar to newfs(8)'s -E option.  This behaviour can be specified by
198	adding -E to swapon(8)'s command-line parameters, or by adding the
199	"trimonce" option to a swap device's /etc/fstab entry.
200
201r347908-r347923:
202	The following network drivers have been removed: bm(4), cs(4), de(4),
203	ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
204	vx(4), wb(4), xe(4).
205
206r347532:
207	Wired page accounting has been split into kernel wirings and user
208	wirings (e.g., by mlock(2)).  Kernel wirings no long count towards
209	the global limit, which is renamed to vm.max_user_wired.  bhyve -S
210	allocates user-wired memory and is now subject to that limit.
