14	Remove support for ARC4, Blowfish, Cast, DES, Triple DES, MD5,
15	MD5-KPDK, MD5-HMAC, SHA1-KPDK, and Skipjack algorithms from
16	the kernel open cryptographic framework (OCF).
17

20	MD5-HMAC, and Skipjack algorithms from /dev/crypto.
21
22r360557:
23	Remove support for DES, Triple DES, Blowfish, Cast, and
24	Camellia ciphers from IPsec(4).  Remove support for MD5-HMAC,
25	Keyed MD5, Keyed SHA1, and RIPEMD160-HMAC from IPsec(4).
26
27r359945:
28	Remove support for Triple DES, Blowfish, and MD5 HMAC from
29	geli(4).
30
31r359786-r359787:
32	Remove support for DES, Triple DES, and RC4 from in-kernel GSS
33	authentication.
34
35r357627:
36	remove elf2aout.
37
38r357560-r357565:
39	init(8), service(8), and cron(8) will now adopt user/class environment
40	variables (excluding PATH, by default, which will be overwritten) by
41	default.  Notably, environment variables for all cron jobs and rc
42	services can now be set via login.conf(5).
43
44r357455:
45	sparc64 has been removed from FreeBSD.
46
47r355677:
48	Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
49	(RFC-8276) to the NFS client and server.
50	NFSv4.2 is comprised of several optional features that can be supported
51	in addition to NFSv4.1. This patch adds the following optional features:
52	- posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
53	- posix_fallocate()
54	- intra server file range copying via the copy_file_range(2) syscall
55	--> Avoiding data tranfer over the wire to/from the NFS client.
56	- lseek(SEEK_DATA/SEEK_HOLE)
57	- Extended attribute syscalls for "user" namespace attributes as defined
58	  by RFC-8276.
59
60	For the client, NFSv4.2 is only used if the mount command line option
61	minorversion=2 is specified.
62	For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
63 	and vfs.nfsd.server_max_minorversion4 have been added that allow
64	sysadmins to limit the minor versions of NFSv4 supported by the nfsd
65	server.
66	Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
67	on the server.
68
69r356263:
70	armv5 support has been removed from FreeBSD.
71
72r354517:
73	iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
74
75r354269:
76	sqlite3 is updated to sqlite3-3.30.1.
77
78r352668:
79	cron(8) now supports the -n (suppress mail on succesful run) and -q
80	(suppress logging of command execution) options in the crontab format.
81	See the crontab(5) manpage for details.
82
83r352304:
84	ntpd is no longer by default locked in memory. rlimit memlock 32
85	or rlimit memlock 0 can be used to restore this behaviour.
86
87r351522:
88	Add kernel-side support for in-kernel Transport Layer Security
89	(KTLS).  KTLS permits using sendfile(2) over sockets using
90	TLS.
91
92r351397:
93	WPA is updated from 2.8 to 2.9.
94
95r351361:
96	Add probes for lockmgr(9) to the lockstat DTrace provider, add
97	corresponding lockstat(1) events, and document the new probes in
98	dtrace_lockstat.4.
99
100r351356:
101	Intel RST is a new 'feature' that remaps NVMe devices from
102	their normal location to part of the AHCI bar space.  This
103	will eliminate the need to set the BIOS SATA setting from RST
104	to AHCI causing the nvme drive to be erased before FreeBSD
105	will see the nvme drive. FreeBSD will now be able to see the
106	nvme drive now in the default config.
107
108r351201, r351372:
109	Add a vop_stdioctl() call, so that file systems that do not support
110	holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
111	The algorithm appears to be compatible with the POSIX draft and
112	the implementation in Linux for the case of a file system that
113	does not support holes.  Prior to this patch, lseek(2) would reply
114	-1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
115	file systems that do not support holes.
116	r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
117	any other cases, such as a ENOTTY return from vn_bmap_seekhole().
118
119r350665:
120	The fuse driver has been renamed to fusefs(5) and been substantially
121	rewritten.  The new driver includes many bug fixes and performance
122	enhancements, as well as the following user-visible features:
123	* Optional kernel-side permissions checks (-o default_permissions)
124	* mknod(2), socket(2), and pipe(2) support
125	* server side locking with fcntl(2)
126	* FUSE operations are now interruptible when mounted with -o intr
127	* server side handling of UTIME_NOW during utimensat(2)
128	* mount options may be updated with "mount -u"
129	* fusefs file system may now be exported over NFS
130	* RLIMIT_FSIZE support
131	* support for fuse file systems using protocols as old as 7.4
132
133	FUSE file system developers should also take note of the following new
134	features:
135	* The protocol level has been raised from 7.8 to 7.23
136	* kqueue support on /dev/fuse
137	* server-initiated cache invalidation via FUSE_NOTIFY_REPLY
138
139r350471:
140	gnop(8) can now configure a delay to be applied to read and write
141	request delays.  See the -d, -q and -x parameters.
142
143r350315, r350316:
144	Adds a Linux compatible copy_file_range(2) syscall.
145
146r350307:
147	libcap_random(3) has been removed.  Applications can use native
148	APIs to get random data in capability mode.
149
150r349529,r349530:
151	Add support for using unmapped mbufs with sendfile(2).
152
153r349352:
154	nand(4) and related components have been removed.
155
156r349349:
157	The UEFI loader now supports HTTP boot.
158
159r349335:
160	bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
161	guests to play to and record audio data from the host.
162
163r349286:
164	swapon(8) can now erase a swap device immediately before enabling it,
165	similar to newfs(8)'s -E option.  This behaviour can be specified by
166	adding -E to swapon(8)'s command-line parameters, or by adding the
167	"trimonce" option to a swap device's /etc/fstab entry.
168
169r347908-r347923:
170	The following network drivers have been removed: bm(4), cs(4), de(4),
171	ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
172	vx(4), wb(4), xe(4).
