1Release notes for FreeBSD 15.0. 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 13822ca3276345: 14 byacc was updated to 20240109. 15 1621817992b331: 17 ncurses was updated to 6.5. 18 191687d77197c0: 20 Filesystem manual pages have been moved to section four. 21 Please check ports you are maintaining for crossreferences. 22 238aac90f18aef: 24 new MAC/do policy and mdo(1) utility which enables a user to 25 become another user without the requirement of setuid root. 26 277398d1ece5cf: 28 hw.snd.version is removed. 29 30a15f7c96a276,a8089ea5aee5: 31 NVMe over Fabrics controller. The nvmft(4) kernel module adds 32 a new frontend to the CAM target layer which exports ctl(4) 33 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 34 is responsible for accepting incoming connection requests and 35 handing off connected queue pairs to nvmft(4). 36 37a1eda74167b5,1058c12197ab: 38 NVMe over Fabrics host. New commands added to nvmecontrol(8) 39 to establish connections to remote controllers. Once 40 connections are established they are handed off to the nvmf(4) 41 kernel module which creates nvmeX devices and exports remote 42 namespaces as nda(4) disks. 43 4425723d66369f: 45 As a side-effect of retiring the unit.* code in sound(4), the 46 hw.snd.maxunit loader(8) tunable is also retired. 47 48eeb04a736cb9: 49 date(1) now supports nanoseconds. For example: 50 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 51 `date +%N` prints "415050400". 52 536d5ce2bb6344: 54 The default value of the nfs_reserved_port_only rc.conf(5) setting has 55 changed. The FreeBSD NFS server now requires the source port of 56 requests to be in the privileged port range (i.e., <= 1023), which 57 generally requires the client to have elevated privileges on their local 58 system. The previous behavior can be restored by setting 59 nfs_reserved_port_only=NO in rc.conf. 60 61aea973501b19: 62 ktrace(2) will now record detailed information about capability mode 63 violations. The kdump(1) utility has been updated to display such 64 information. 65 66f32a6403d346: 67 One True Awk updated to 2nd Edition. See https://awk.dev for details 68 on the additions. Unicode and CSVs (Comma Separated Values) are now 69 supported. 70 71fe86d923f83f: 72 usbconfig(8) now reads the descriptions of the usb vendor and products 73 from usb.ids when available, similarly to what pciconf(8) does. 74 754347ef60501f: 76 The powerd(8) utility is now enabled in /etc/rc.conf by default on 77 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 78 This prevents the CPU clock from running slow all the time. 79 800b49e504a32d: 81 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 82 to allow unmaintained jail managers like ezjail to make use of this 83 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 84 config to jail_${jailname}_zfs_dataset. 85 86e0dfe185cbca: 87 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 88 jail. 89 9061174ad88e33: 91 newsyslog(8) now supports specifying a global compression method directly 92 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 93 to behave like the corresponding option was passed to the newly added 94 '-c' option. For example: 95 96 <compress> none 97 98906748d208d3: 99 newsyslog(8) now accepts a new option, '-c' which overrides all historical 100 compression flags by treating their meaning as "treat the file as compressible" 101 rather than "compress the file with that specific method." 102 103 The following choices are available: 104 * none: Do not compress, regardless of flag. 105 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 106 * bzip2, xz, zstd, gzip: apply the specified compression method. 107 108 We plan to change the default to 'none' in FreeBSD 15.0. 109 1101a878807006c: 111 This commit added some statistics collection to the NFS-over-TLS 112 code in the NFS server so that sysadmins can moditor usage. 113 The statistics are available via the kern.rpc.tls.* sysctls. 114 1157c5146da1286: 116 Mountd has been modified to use strunvis(3) to decode directory 117 names in exports(5) file(s). This allows special characters, 118 such as blanks, to be embedded in the directory name(s). 119 "vis -M" may be used to encode such directory name(s). 120 121c5359e2af5ab: 122 bhyve(8) has a new network backend, "slirp", which makes use of the 123 libslirp package to provide a userspace network stack. This backend 124 makes it possible to access the guest network from the host without 125 requiring any extra network configuration on the host. 126 127bb830e346bd5: 128 Set the IUTF8 flag by default in tty(4). 129 130 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 131 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 132 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 133 default. 134 135ff01d71e48d4: 136 dialog(1) has been replaced by bsddialog(1) 137 13841582f28ddf7: 139 FreeBSD 15.0 will not include support for 32-bit platforms. 140 However, 64-bit systems will still be able to run older 32-bit 141 binaries. 142 143 Support for executing 32-bit binaries on 64-bit platforms via 144 COMPAT_FREEBSD32 will remain supported for at least the 145 stable/15 and stable/16 branches. 146 147 Support for compiling individual 32-bit applications via 148 `cc -m32` will also be supported for at least the stable/15 149 branch which includes suitable headers in /usr/include and 150 libraries in /usr/lib32. 151 152 Support for 32-bit platforms in ports for 15.0 and later 153 releases is also deprecated, and these future releases may not 154 include binary packages for 32-bit platforms or support for 155 building 32-bit applications from ports. 156 157 stable/14 and earlier branches will retain existing 32-bit 158 kernel and world support. Ports will retain existing support 159 for building ports and packages for 32-bit systems on stable/14 160 and earlier branches as long as those branches are supported 161 by the ports system. However, all 32-bit platforms are Tier-2 162 or Tier-3 and support for individual ports should be expected 163 to degrade as upstreams deprecate 32-bit platforms. 164 165 With the current support schedule, stable/14 will be EOLed 5 166 years after the release of 14.0. The EOL of stable/14 would 167 mark the end of support for 32-bit platforms including source 168 releases, pre-built packages, and support for building 169 applications from ports. Given an estimated release date of 170 October 2023 for 14.0, support for 32-bit platforms would end 171 in October 2028. 172 173 The project may choose to alter this approach when 15.0 is 174 released by extending some level of 32-bit support for one or 175 more platforms in 15.0 or later. Users should use the 176 stable/14 branch to migrate off of 32-bit platforms. 177
