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 13f87bb5967670, e51036fbf3f8: 14 Support for vinum volumes has been removed. 15 168ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151: 17 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 18 file systems has changed. An NFS server that exports any of these file 19 systems will need its clients to unmount and remount the exports. 20 211111a44301da: 22 Defer the January 19, 2038 date limit in UFS1 filesystems to 23 February 7, 2106. This affects only UFS1 format filesystems. 24 See the commit message for details. 25 2607cd69e272da: 27 Add a new -a command line option to mountd(8). 28 If this command line option is specified, when 29 a line in exports(5) has the -alldirs export option, 30 the directory must be a server file system mount point. 31 320e8a36a2ab12: 33 Add a new NFS mount option called "mountport" that may be used 34 to specify the port# for the NFS server's Mount protocol. 35 This permits a NFSv3 mount to be done without running rpcbind(8). 36 37b2f7c53430c3: 38 Kernel TLS is now enabled by default in kernels including KTLS 39 support. KTLS is included in GENERIC kernels for aarch64, 40 amd64, powerpc64, and powerpc64le. 41 42f57efe95cc25: 43 New mididump(1) utility which dumps MIDI 1.0 events in real time. 44 45ddfc6f84f242: 46 Update unicode to 16.0.0 and CLDR to 45.0.0. 47 48b22be3bbb2de: 49 Basic Cloudinit images no longer generate RSA host keys by default for 50 SSH. 51 52000000000000: 53 RSA host keys for SSH are deprecated and will no longer be generated 54 by default in FreeBSD 16. 55 560aabcd75dbc2: 57 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 58 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 59 in /etc/rc.conf if it is necessary to support very old SSH clients. 60 61a1da7dc1cdad: 62 The SO_SPLICE socket option was added. It allows TCP connections to 63 be spliced together, enabling proxy-like functionality without the 64 need to copy data in and out of user memory. 65 66fc12c191c087: 67 grep(1) no longer follows symbolic links by default for 68 recursive searches. This matches the documented behavior in 69 the manual page. 70 71e962b37bf0ff: 72 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 73 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 74 This is incompatible with some boot ROMs, particularly outdated builds 75 of edk2-bhyve. To restore the old behavior, add 76 "pci.enable_bars='true'" to your bhyve configuration. 77 78 Note in particular that the uefi-edk2-bhyve package has been renamed 79 to edk2-bhyve. 80 8143caa2e805c2: 82 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 83 deprecated. Use the top-level "bootrom" and "bootvars" options 84 instead. 85 86822ca3276345: 87 byacc was updated to 20240109. 88 8921817992b331: 90 ncurses was updated to 6.5. 91 921687d77197c0: 93 Filesystem manual pages have been moved to section four. 94 Please check ports you are maintaining for crossreferences. 95 968aac90f18aef: 97 new MAC/do policy and mdo(1) utility which enables a user to 98 become another user without the requirement of setuid root. 99 1007398d1ece5cf: 101 hw.snd.version is removed. 102 103a15f7c96a276,a8089ea5aee5: 104 NVMe over Fabrics controller. The nvmft(4) kernel module adds 105 a new frontend to the CAM target layer which exports ctl(4) 106 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 107 is responsible for accepting incoming connection requests and 108 handing off connected queue pairs to nvmft(4). 109 110a1eda74167b5,1058c12197ab: 111 NVMe over Fabrics host. New commands added to nvmecontrol(8) 112 to establish connections to remote controllers. Once 113 connections are established they are handed off to the nvmf(4) 114 kernel module which creates nvmeX devices and exports remote 115 namespaces as nda(4) disks. 116 11725723d66369f: 118 As a side-effect of retiring the unit.* code in sound(4), the 119 hw.snd.maxunit loader(8) tunable is also retired. 120 121eeb04a736cb9: 122 date(1) now supports nanoseconds. For example: 123 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 124 `date +%N` prints "415050400". 125 1266d5ce2bb6344: 127 The default value of the nfs_reserved_port_only rc.conf(5) setting has 128 changed. The FreeBSD NFS server now requires the source port of 129 requests to be in the privileged port range (i.e., <= 1023), which 130 generally requires the client to have elevated privileges on their local 131 system. The previous behavior can be restored by setting 132 nfs_reserved_port_only=NO in rc.conf. 133 134aea973501b19: 135 ktrace(2) will now record detailed information about capability mode 136 violations. The kdump(1) utility has been updated to display such 137 information. 138 139f32a6403d346: 140 One True Awk updated to 2nd Edition. See https://awk.dev for details 141 on the additions. Unicode and CSVs (Comma Separated Values) are now 142 supported. 143 144fe86d923f83f: 145 usbconfig(8) now reads the descriptions of the usb vendor and products 146 from usb.ids when available, similarly to what pciconf(8) does. 147 1484347ef60501f: 149 The powerd(8) utility is now enabled in /etc/rc.conf by default on 150 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 151 This prevents the CPU clock from running slow all the time. 152 1530b49e504a32d: 154 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 155 to allow unmaintained jail managers like ezjail to make use of this 156 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 157 config to jail_${jailname}_zfs_dataset. 158 159e0dfe185cbca: 160 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 161 jail. 162 16361174ad88e33: 164 newsyslog(8) now supports specifying a global compression method directly 165 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 166 to behave like the corresponding option was passed to the newly added 167 '-c' option. For example: 168 169 <compress> none 170 171906748d208d3: 172 newsyslog(8) now accepts a new option, '-c' which overrides all historical 173 compression flags by treating their meaning as "treat the file as compressible" 174 rather than "compress the file with that specific method." 175 176 The following choices are available: 177 * none: Do not compress, regardless of flag. 178 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 179 * bzip2, xz, zstd, gzip: apply the specified compression method. 180 181 We plan to change the default to 'none' in FreeBSD 15.0. 182 1831a878807006c: 184 This commit added some statistics collection to the NFS-over-TLS 185 code in the NFS server so that sysadmins can moditor usage. 186 The statistics are available via the kern.rpc.tls.* sysctls. 187 1887c5146da1286: 189 Mountd has been modified to use strunvis(3) to decode directory 190 names in exports(5) file(s). This allows special characters, 191 such as blanks, to be embedded in the directory name(s). 192 "vis -M" may be used to encode such directory name(s). 193 194c5359e2af5ab: 195 bhyve(8) has a new network backend, "slirp", which makes use of the 196 libslirp package to provide a userspace network stack. This backend 197 makes it possible to access the guest network from the host without 198 requiring any extra network configuration on the host. 199 200bb830e346bd5: 201 Set the IUTF8 flag by default in tty(4). 202 203 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 204 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 205 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 206 default. 207 208ff01d71e48d4: 209 dialog(1) has been replaced by bsddialog(1) 210 21141582f28ddf7: 212 FreeBSD 15.0 will not include support for 32-bit platforms. 213 However, 64-bit systems will still be able to run older 32-bit 214 binaries. 215 216 Support for executing 32-bit binaries on 64-bit platforms via 217 COMPAT_FREEBSD32 will remain supported for at least the 218 stable/15 and stable/16 branches. 219 220 Support for compiling individual 32-bit applications via 221 `cc -m32` will also be supported for at least the stable/15 222 branch which includes suitable headers in /usr/include and 223 libraries in /usr/lib32. 224 225 Support for 32-bit platforms in ports for 15.0 and later 226 releases is also deprecated, and these future releases may not 227 include binary packages for 32-bit platforms or support for 228 building 32-bit applications from ports. 229 230 stable/14 and earlier branches will retain existing 32-bit 231 kernel and world support. Ports will retain existing support 232 for building ports and packages for 32-bit systems on stable/14 233 and earlier branches as long as those branches are supported 234 by the ports system. However, all 32-bit platforms are Tier-2 235 or Tier-3 and support for individual ports should be expected 236 to degrade as upstreams deprecate 32-bit platforms. 237 238 With the current support schedule, stable/14 will be EOLed 5 239 years after the release of 14.0. The EOL of stable/14 would 240 mark the end of support for 32-bit platforms including source 241 releases, pre-built packages, and support for building 242 applications from ports. Given an estimated release date of 243 October 2023 for 14.0, support for 32-bit platforms would end 244 in October 2028. 245 246 The project may choose to alter this approach when 15.0 is 247 released by extending some level of 32-bit support for one or 248 more platforms in 15.0 or later. Users should use the 249 stable/14 branch to migrate off of 32-bit platforms. 250
