1Release notes for FreeBSD 13.0. 2 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. 10 11Changes to this file should not be MFCed. 12 13r351201: 14 Add a vop_stdioctl() call, so that file systems that do not support 15 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 16 The algorithm appears to be compatible with the POSIX draft and 17 the implementation in Linux for the case of a file system that 18 does not support holes. Prior to this patch, lseek(2) would reply 19 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 20 file systems that do not support holes. 21 22r350665: 23 The fuse driver has been renamed to fusefs(5) and been substantially 24 rewritten. The new driver includes many bug fixes and performance 25 enhancements, as well as the following user-visible features: 26 * Optional kernel-side permissions checks (-o default_permissions) 27 * mknod(2), socket(2), and pipe(2) support 28 * server side locking with fcntl(2) 29 * FUSE operations are now interruptible when mounted with -o intr 30 * server side handling of UTIME_NOW during utimensat(2) 31 * mount options may be updated with "mount -u" 32 * fusefs file system may now be exported over NFS 33 * RLIMIT_FSIZE support 34 * support for fuse file systems using protocols as old as 7.4 35 36 FUSE file system developers should also take note of the following new 37 features: 38 * The protocol level has been raised from 7.8 to 7.23 39 * kqueue support on /dev/fuse 40 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 41 42r350471: 43 gnop(8) can now configure a delay to be applied to read and write 44 request delays. See the -d, -q and -x parameters. 45 46r350315, r350316: 47 Adds a Linux compatible copy_file_range(2) syscall. 48 49r350307: 50 libcap_random(3) has been removed. Applications can use native 51 APIs to get random data in capability mode. 52 53r349352: 54 nand(4) and related components have been removed. 55 56r349349: 57 The UEFI loader now supports HTTP boot. 58 59r349335: 60 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 61 guests to play to and record audio data from the host. 62 63r349286: 64 swapon(8) can now erase a swap device immediately before enabling it, 65 similar to newfs(8)'s -E option. This behaviour can be specified by 66 adding -E to swapon(8)'s command-line parameters, or by adding the 67 "trimonce" option to a swap device's /etc/fstab entry. 68 69r347908-r347923: 70 The following network drivers have been removed: bm(4), cs(4), de(4), 71 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 72 vx(4), wb(4), xe(4). 73 74$FreeBSD$ 75
