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 ntpd is no longer by default locked in memory. rlimit memlock 32
15 or rlimit memlock 0 can be used to restore this behaviour.
18 Add kernel-side support for in-kernel Transport Layer Security
19 (KTLS). KTLS permits using sendfile(2) over sockets using
23 Add probes for lockmgr(9) to the lockstat DTrace provider, add
24 corresponding lockstat(1) events, and document the new probes in
28 Intel RST is a new 'feature' that remaps NVMe devices from
29 their normal location to part of the AHCI bar space. This
30 will eliminate the need to set the BIOS SATA setting from RST
31 to AHCI causing the nvme drive to be erased before FreeBSD
32 will see the nvme drive. FreeBSD will now be able to see the
33 nvme drive now in the default config.
36 Add a vop_stdioctl() call, so that file systems that do not support
37 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
38 The algorithm appears to be compatible with the POSIX draft and
39 the implementation in Linux for the case of a file system that
40 does not support holes. Prior to this patch, lseek(2) would reply
41 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
42 file systems that do not support holes.
43 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
44 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
47 The fuse driver has been renamed to fusefs(5) and been substantially
48 rewritten. The new driver includes many bug fixes and performance
49 enhancements, as well as the following user-visible features:
50 * Optional kernel-side permissions checks (-o default_permissions)
51 * mknod(2), socket(2), and pipe(2) support
52 * server side locking with fcntl(2)
53 * FUSE operations are now interruptible when mounted with -o intr
54 * server side handling of UTIME_NOW during utimensat(2)
55 * mount options may be updated with "mount -u"
56 * fusefs file system may now be exported over NFS
57 * RLIMIT_FSIZE support
58 * support for fuse file systems using protocols as old as 7.4
60 FUSE file system developers should also take note of the following new
62 * The protocol level has been raised from 7.8 to 7.23
63 * kqueue support on /dev/fuse
64 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
67 gnop(8) can now configure a delay to be applied to read and write
68 request delays. See the -d, -q and -x parameters.
71 Adds a Linux compatible copy_file_range(2) syscall.
74 libcap_random(3) has been removed. Applications can use native
75 APIs to get random data in capability mode.
78 Add support for using unmapped mbufs with sendfile(2).
81 nand(4) and related components have been removed.
84 The UEFI loader now supports HTTP boot.
87 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
88 guests to play to and record audio data from the host.
91 swapon(8) can now erase a swap device immediately before enabling it,
92 similar to newfs(8)'s -E option. This behaviour can be specified by
93 adding -E to swapon(8)'s command-line parameters, or by adding the
94 "trimonce" option to a swap device's /etc/fstab entry.
97 The following network drivers have been removed: bm(4), cs(4), de(4),
98 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
