1 Release notes for FreeBSD 13.0.
3 This file describes new user-visible features, changes and updates relevant to
4 users of binary FreeBSD releases. Each entry should describe the change in no
5 more than several sentences and should reference manual pages where an
6 interested user can find more information. Entries should wrap after 80
7 columns. Each entry should begin with one or more commit IDs on one line,
8 specified as a comma separated list and/or range, followed by a colon and a
9 newline. Entries should be separated by a newline.
11 Changes to this file should not be MFCed.
14 init(8), service(8), and cron(8) will now adopt user/class environment
15 variables (excluding PATH, by default, which will be overwritten) by
16 default. Notably, environment variables for all cron jobs and rc
17 services can now be set via login.conf(5).
20 sparc64 has been removed from FreeBSD.
23 Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
24 (RFC-8276) to the NFS client and server.
25 NFSv4.2 is comprised of several optional features that can be supported
26 in addition to NFSv4.1. This patch adds the following optional features:
27 - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
29 - intra server file range copying via the copy_file_range(2) syscall
30 --> Avoiding data tranfer over the wire to/from the NFS client.
31 - lseek(SEEK_DATA/SEEK_HOLE)
32 - Extended attribute syscalls for "user" namespace attributes as defined
35 For the client, NFSv4.2 is only used if the mount command line option
36 minorversion=2 is specified.
37 For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
38 and vfs.nfsd.server_max_minorversion4 have been added that allow
39 sysadmins to limit the minor versions of NFSv4 supported by the nfsd
41 Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
45 armv5 support has been removed from FreeBSD.
48 iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
51 sqlite3 is updated to sqlite3-3.30.1.
54 cron(8) now supports the -n (suppress mail on succesful run) and -q
55 (suppress logging of command execution) options in the crontab format.
56 See the crontab(5) manpage for details.
59 ntpd is no longer by default locked in memory. rlimit memlock 32
60 or rlimit memlock 0 can be used to restore this behaviour.
63 Add kernel-side support for in-kernel Transport Layer Security
64 (KTLS). KTLS permits using sendfile(2) over sockets using
68 WPA is updated from 2.8 to 2.9.
71 Add probes for lockmgr(9) to the lockstat DTrace provider, add
72 corresponding lockstat(1) events, and document the new probes in
76 Intel RST is a new 'feature' that remaps NVMe devices from
77 their normal location to part of the AHCI bar space. This
78 will eliminate the need to set the BIOS SATA setting from RST
79 to AHCI causing the nvme drive to be erased before FreeBSD
80 will see the nvme drive. FreeBSD will now be able to see the
81 nvme drive now in the default config.
84 Add a vop_stdioctl() call, so that file systems that do not support
85 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
86 The algorithm appears to be compatible with the POSIX draft and
87 the implementation in Linux for the case of a file system that
88 does not support holes. Prior to this patch, lseek(2) would reply
89 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
90 file systems that do not support holes.
91 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
92 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
95 The fuse driver has been renamed to fusefs(5) and been substantially
96 rewritten. The new driver includes many bug fixes and performance
97 enhancements, as well as the following user-visible features:
98 * Optional kernel-side permissions checks (-o default_permissions)
99 * mknod(2), socket(2), and pipe(2) support
100 * server side locking with fcntl(2)
101 * FUSE operations are now interruptible when mounted with -o intr
102 * server side handling of UTIME_NOW during utimensat(2)
103 * mount options may be updated with "mount -u"
104 * fusefs file system may now be exported over NFS
105 * RLIMIT_FSIZE support
106 * support for fuse file systems using protocols as old as 7.4
108 FUSE file system developers should also take note of the following new
110 * The protocol level has been raised from 7.8 to 7.23
111 * kqueue support on /dev/fuse
112 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
115 gnop(8) can now configure a delay to be applied to read and write
116 request delays. See the -d, -q and -x parameters.
119 Adds a Linux compatible copy_file_range(2) syscall.
122 libcap_random(3) has been removed. Applications can use native
123 APIs to get random data in capability mode.
126 Add support for using unmapped mbufs with sendfile(2).
129 nand(4) and related components have been removed.
132 The UEFI loader now supports HTTP boot.
135 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
136 guests to play to and record audio data from the host.
139 swapon(8) can now erase a swap device immediately before enabling it,
140 similar to newfs(8)'s -E option. This behaviour can be specified by
141 adding -E to swapon(8)'s command-line parameters, or by adding the
142 "trimonce" option to a swap device's /etc/fstab entry.
145 The following network drivers have been removed: bm(4), cs(4), de(4),
146 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
