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 13r352668: 14 cron(8) now supports the -n (suppress mail on succesful run) and -q 15 (suppress logging of command execution) options in the crontab format. 16 See the crontab(5) manpage for details. 17 18r352304: 19 ntpd is no longer by default locked in memory. rlimit memlock 32 20 or rlimit memlock 0 can be used to restore this behaviour. 21 22r351522: 23 Add kernel-side support for in-kernel Transport Layer Security 24 (KTLS). KTLS permits using sendfile(2) over sockets using 25 TLS. 26 27r351361: 28 Add probes for lockmgr(9) to the lockstat DTrace provider, add 29 corresponding lockstat(1) events, and document the new probes in 30 dtrace_lockstat.4. 31 32r351356: 33 Intel RST is a new 'feature' that remaps NVMe devices from 34 their normal location to part of the AHCI bar space. This 35 will eliminate the need to set the BIOS SATA setting from RST 36 to AHCI causing the nvme drive to be erased before FreeBSD 37 will see the nvme drive. FreeBSD will now be able to see the 38 nvme drive now in the default config. 39 40r351201, r351372: 41 Add a vop_stdioctl() call, so that file systems that do not support 42 holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE). 43 The algorithm appears to be compatible with the POSIX draft and 44 the implementation in Linux for the case of a file system that 45 does not support holes. Prior to this patch, lseek(2) would reply 46 -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in 47 file systems that do not support holes. 48 r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for 49 any other cases, such as a ENOTTY return from vn_bmap_seekhole(). 50 51r350665: 52 The fuse driver has been renamed to fusefs(5) and been substantially 53 rewritten. The new driver includes many bug fixes and performance 54 enhancements, as well as the following user-visible features: 55 * Optional kernel-side permissions checks (-o default_permissions) 56 * mknod(2), socket(2), and pipe(2) support 57 * server side locking with fcntl(2) 58 * FUSE operations are now interruptible when mounted with -o intr 59 * server side handling of UTIME_NOW during utimensat(2) 60 * mount options may be updated with "mount -u" 61 * fusefs file system may now be exported over NFS 62 * RLIMIT_FSIZE support 63 * support for fuse file systems using protocols as old as 7.4 64 65 FUSE file system developers should also take note of the following new 66 features: 67 * The protocol level has been raised from 7.8 to 7.23 68 * kqueue support on /dev/fuse 69 * server-initiated cache invalidation via FUSE_NOTIFY_REPLY 70 71r350471: 72 gnop(8) can now configure a delay to be applied to read and write 73 request delays. See the -d, -q and -x parameters. 74 75r350315, r350316: 76 Adds a Linux compatible copy_file_range(2) syscall. 77 78r350307: 79 libcap_random(3) has been removed. Applications can use native 80 APIs to get random data in capability mode. 81 82r349529,r349530: 83 Add support for using unmapped mbufs with sendfile(2). 84 85r349352: 86 nand(4) and related components have been removed. 87 88r349349: 89 The UEFI loader now supports HTTP boot. 90 91r349335: 92 bhyve(8) now implements a High Definition Audio (HDA) driver, allowing 93 guests to play to and record audio data from the host. 94 95r349286: 96 swapon(8) can now erase a swap device immediately before enabling it, 97 similar to newfs(8)'s -E option. This behaviour can be specified by 98 adding -E to swapon(8)'s command-line parameters, or by adding the 99 "trimonce" option to a swap device's /etc/fstab entry. 100 101r347908-r347923: 102 The following network drivers have been removed: bm(4), cs(4), de(4), 103 ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4), 104 vx(4), wb(4), xe(4). 105 106$FreeBSD$ 107
