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 Add kernel-side support for in-kernel Transport Layer Security
15 (KTLS). KTLS permits using sendfile(2) over sockets using
19 Add probes for lockmgr(9) to the lockstat DTrace provider, add
20 corresponding lockstat(1) events, and document the new probes in
24 Intel RST is a new 'feature' that remaps NVMe devices from
25 their normal location to part of the AHCI bar space. This
26 will eliminate the need to set the BIOS SATA setting from RST
27 to AHCI causing the nvme drive to be erased before FreeBSD
28 will see the nvme drive. FreeBSD will now be able to see the
29 nvme drive now in the default config.
32 Add a vop_stdioctl() call, so that file systems that do not support
33 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
34 The algorithm appears to be compatible with the POSIX draft and
35 the implementation in Linux for the case of a file system that
36 does not support holes. Prior to this patch, lseek(2) would reply
37 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
38 file systems that do not support holes.
39 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
40 any other cases, such as a ENOTTY return from vn_bmap_seekhole().
43 The fuse driver has been renamed to fusefs(5) and been substantially
44 rewritten. The new driver includes many bug fixes and performance
45 enhancements, as well as the following user-visible features:
46 * Optional kernel-side permissions checks (-o default_permissions)
47 * mknod(2), socket(2), and pipe(2) support
48 * server side locking with fcntl(2)
49 * FUSE operations are now interruptible when mounted with -o intr
50 * server side handling of UTIME_NOW during utimensat(2)
51 * mount options may be updated with "mount -u"
52 * fusefs file system may now be exported over NFS
53 * RLIMIT_FSIZE support
54 * support for fuse file systems using protocols as old as 7.4
56 FUSE file system developers should also take note of the following new
58 * The protocol level has been raised from 7.8 to 7.23
59 * kqueue support on /dev/fuse
60 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
63 gnop(8) can now configure a delay to be applied to read and write
64 request delays. See the -d, -q and -x parameters.
67 Adds a Linux compatible copy_file_range(2) syscall.
70 libcap_random(3) has been removed. Applications can use native
71 APIs to get random data in capability mode.
74 Add support for using unmapped mbufs with sendfile(2).
77 nand(4) and related components have been removed.
80 The UEFI loader now supports HTTP boot.
83 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
84 guests to play to and record audio data from the host.
87 swapon(8) can now erase a swap device immediately before enabling it,
88 similar to newfs(8)'s -E option. This behaviour can be specified by
89 adding -E to swapon(8)'s command-line parameters, or by adding the
90 "trimonce" option to a swap device's /etc/fstab entry.
93 The following network drivers have been removed: bm(4), cs(4), de(4),
94 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
