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
13ab9257599a5:
14	The src.conf(5) options WITHOUT_BZIP2 and WITHOUT_BZIP2_SUPPORT
15	have been removed.
16
17af099eaa5ec:
18	Users belonging to the new vmm group can now create bhyve VMs.  See the
19	vmm(4) man page for details.
20
21c71354030a2:
22	Users wishing to use bhyve PCI passthrough in jails must create the
23	jail with the allow.vmm_ppt option configured.
24
254d707825bf62:
26	The pdwait(2) system call was added.  It provides wait(2)-like
27	functionality for a process descriptor (see procdesc(4)).
28
295c2ee618d5ec:
30	The pdrfork(2) system call was added.  It behaves like rfork(2) but
31	additionally returns a process descriptor (see procdesc(4)).
32
3341ccf82b29f3, 591c7a08bf8a:
34	On arm64, memcpy(3), memmove(3) and memset(3) are now implemented using
35	the MOPS (Memory Operations) feature instructions when they are
36	implemented by the system.
37
383f0aea09689f:
39	posix_spawnattr_getexecfd_np(3) and posix_spawnattr_setexecfd_np(3)
40	functions were added to libc.  The latter causes posix_spawn(3) to
41	call fexecve(2) on the specified file descriptor rather than executing
42	the file at the provided path.
43
44fb4b0c911951:
45	witness(4) now prints additional information to the system console when
46	a lock order reversal is detected, making debugging such issues easier.
47
481322760fd127:
49	It is now possible to compile both the 4BSD and ULE schedulers into the
50	same kernel.  The scheduler is selectable at boot-time using a tunable.
51	See the SCHEDULERS section of the tuning(7) man page for details.
52
53627e126dbb07:
54	The default value of the net.inet6.ip6.connect_in6addr_wild has changed
55	to 0.  This means that connecting to the all-zeroes IPv6 address no longer
56	implicitly results in a loopback connection.
57
58afa70a8496e9:
59	The pthread_tryjoin_np(3) function was added to libthr(3).  It provides
60	the same functionality as pthread_join(3) but returns instead of
61	blocking if the target thread has not yet exited.
62
63ecc039be7fdd:
64	NanoBSD images can now be built as a non-root user.
65
667f54c65abc67:
67        Update smartpqi(4) to vendor version 14.4690.0.2008 - 15.2.0.2008
68        for the SmartArray storage controllers.  This adds support for new
69        controllers, adds code that utilizes the new BIG_IOCTL_Command_struct
70        and allows the I/O buffer size for a single passthrough ioctl to be
71        stored as a 32 bit integer instead of the original 16 bit integer.
72
73b0d997095022:
74	The pf firewall now supports passing IPv6 packets to divert(4)
75	sockets via divert-to actions.
76
770fa7b3bee72e, c71f18998e0b, 4162a419a475, f5a77dc8f8df:
78	LinuxKPI based wireless drivers, especially iwlwifi(4) are now
79	supported on RISC-V.
80
818254b0dec02b3, bd55cbb50c588:
82	The mac(4) framework has been extended to support jail operations,
83	allowing a policy to constrain jail creation, modification, removal, and
84	attachment.  Jails have additionally been made a first-class mac(4)
85	object, and a mac.label jail(8) property has been added to facilitate
86	administration of their labels.
87
88c558eca47970:
89	The smartpqi(4) driver was updated to vendor version 4660.0.2002
90	for the SmartArry storage controllers.
91
92493d26c58e73:
93	The aq(4) driver was added, imported from the vendor repository.
94	This provides support for Aquantia / Marvell PCIe 1/2.5/5/10 Gigabit
95	Ethernet adapters (AQC107, AQC108, AQC109, AQC111, AQC112).
96
971a7151f79664:
98	A new CAM provider was added to dtrace.  This enables tracing of I/O
99	requests through the CAM layer without relying on fragile function
100	boundary tracing.  See dtrace_cam(4) for details.
101
102b8c99e7d912f:
103	The tdestroy(3) function was added to libc.  The tdestroy() function
104	destroys a whole search tree, freeing all allocated nodes.
105
1064bf8ce037dc8:
107	The rge(4) driver was added, ported from OpenBSD.  This provides
108	support for RealTek RTL8125, RTL8126 and RTL8127 PCIe Ethernet
109	controllers.
110
111cbc6f7e941e4:
112	bhyve(8)'s VNC device can now listen on a unix(4) socket for VNC client
113	connections.
114
11539ee24182b92:
116	An rc(8) service can now be started as a specific user for auditing
117	purposes by setting the <service>_audit_user rc.conf(5) variable.
118
119dcb0790bad43:
120	A setaudit(8) utility was added to the base system.  This provides a
121	simple command-line wrapper for the setaudit(2) and setaudit_addr(2)
122	system calls.
123
1248e3fd450cc53, 949cff4dceff, 0e724de9ed6f, 9f49f436a9ec, e35191ccf3b3:
125	Add support for an extension to NFSv4.2 (RFCnnnn) that
126	supports handling of POSIX draft ACLs via getfacl(1)/setfacl(1).
127
128dbac191956f9, fe21dbf70aa8:
129	Support for the kcmp(2) system call and fcntl(F_DUPFD_QUERY) for Linux
130	binaries.
131
132a86dc94b84d1:
133	tzdata2025c was imported.
134
135a98e5d785001:
136	Add strdupa(3) and strndupa(3) macros for compatability with glibc.
137
138e967a2a03677:
139	divert socket compat removal, consumers must use PF_DIVERT instead of
140	PF_INET.
141
1424453ec5b8716b, 2a3b1641756a:
143	The reboot(8) and halt(8) commands now perform a graceful shutdown similar
144	to the shutdown(8) command including invoking rc.d scripts to shutdown
145	services.  The fastboot(8) and fasthalt(8) commands still perform a "fast"
146	reboot or shutdown.
147
148d9788eabffa4:
149	ipfilter cannot be used in a jail by default.
150
1510ff0c19e7f70:
152	ipfs(8) is no longer built by default.
153
154575efcfff22f:
155	sendfile(2)'s SF_SYNC flag was removed.
156
157057dae35ffc6, 51a01f3debff, ca3e47b0ea68:
158	hwpmc(4) support for Intel Alder Lake 6-B7, 6-BA, and 6-BF CPU
159	hwpmc(4) support for Intel Emerald Rapids CPUs
160	hwpmc(4) support for Intel Alder Lake-N CPUs
161
1621ecf01065b45:
163	New library libuvmem provides the vmem(9) API to userspace applications.
164
165b6cad334e64:

171	USB to serial devices.
172
173ec0cd287f55f:
174	Support for NVMe/TCP offload on Chelsio T7 adapters.  The nvmf_che(4)
175	module enables T7 adapters to process NVMe/TCP PDUs directly similar to
176	the PDU offload provided by cxgbei(4) for iSCSI.
