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 1307cd69e272da: 14 Add a new -a command line option to mountd(8). 15 If this command line option is specified, when 16 a line in exports(5) has the -alldirs export option, 17 the directory must be a server file system mount point. 18 190e8a36a2ab12: 20 Add a new NFS mount option called "mountport" that may be used 21 to specify the port# for the NFS server's Mount protocol. 22 This permits a NFSv3 mount to be done without running rpcbind(8). 23 24b2f7c53430c3: 25 Kernel TLS is now enabled by default in kernels including KTLS 26 support. KTLS is included in GENERIC kernels for aarch64, 27 amd64, powerpc64, and powerpc64le. 28 29f57efe95cc25: 30 New mididump(1) utility which dumps MIDI 1.0 events in real time. 31 32ddfc6f84f242: 33 Update unicode to 16.0.0 and CLDR to 45.0.0. 34 35b22be3bbb2de: 36 Basic Cloudinit images no longer generate RSA host keys by default for 37 SSH. 38 39000000000000: 40 RSA host keys for SSH are deprecated and will no longer be generated 41 by default in FreeBSD 16. 42 430aabcd75dbc2: 44 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 45 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 46 in /etc/rc.conf if it is necessary to support very old SSH clients. 47 48a1da7dc1cdad: 49 The SO_SPLICE socket option was added. It allows TCP connections to 50 be spliced together, enabling proxy-like functionality without the 51 need to copy data in and out of user memory. 52 53fc12c191c087: 54 grep(1) no longer follows symbolic links by default for 55 recursive searches. This matches the documented behavior in 56 the manual page. 57 58e962b37bf0ff: 59 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 60 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 61 This is incompatible with some boot ROMs, particularly outdated builds 62 of edk2-bhyve. To restore the old behavior, add 63 "pci.enable_bars='true'" to your bhyve configuration. 64 65 Note in particular that the uefi-edk2-bhyve package has been renamed 66 to edk2-bhyve. 67 6843caa2e805c2: 69 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 70 deprecated. Use the top-level "bootrom" and "bootvars" options 71 instead. 72 73822ca3276345: 74 byacc was updated to 20240109. 75 7621817992b331: 77 ncurses was updated to 6.5. 78 791687d77197c0: 80 Filesystem manual pages have been moved to section four. 81 Please check ports you are maintaining for crossreferences. 82 838aac90f18aef: 84 new MAC/do policy and mdo(1) utility which enables a user to 85 become another user without the requirement of setuid root. 86 877398d1ece5cf: 88 hw.snd.version is removed. 89 90a15f7c96a276,a8089ea5aee5: 91 NVMe over Fabrics controller. The nvmft(4) kernel module adds 92 a new frontend to the CAM target layer which exports ctl(4) 93 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 94 is responsible for accepting incoming connection requests and 95 handing off connected queue pairs to nvmft(4). 96 97a1eda74167b5,1058c12197ab: 98 NVMe over Fabrics host. New commands added to nvmecontrol(8) 99 to establish connections to remote controllers. Once 100 connections are established they are handed off to the nvmf(4) 101 kernel module which creates nvmeX devices and exports remote 102 namespaces as nda(4) disks. 103 10425723d66369f: 105 As a side-effect of retiring the unit.* code in sound(4), the 106 hw.snd.maxunit loader(8) tunable is also retired. 107 108eeb04a736cb9: 109 date(1) now supports nanoseconds. For example: 110 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 111 `date +%N` prints "415050400". 112 1136d5ce2bb6344: 114 The default value of the nfs_reserved_port_only rc.conf(5) setting has 115 changed. The FreeBSD NFS server now requires the source port of 116 requests to be in the privileged port range (i.e., <= 1023), which 117 generally requires the client to have elevated privileges on their local 118 system. The previous behavior can be restored by setting 119 nfs_reserved_port_only=NO in rc.conf. 120 121aea973501b19: 122 ktrace(2) will now record detailed information about capability mode 123 violations. The kdump(1) utility has been updated to display such 124 information. 125 126f32a6403d346: 127 One True Awk updated to 2nd Edition. See https://awk.dev for details 128 on the additions. Unicode and CSVs (Comma Separated Values) are now 129 supported. 130 131fe86d923f83f: 132 usbconfig(8) now reads the descriptions of the usb vendor and products 133 from usb.ids when available, similarly to what pciconf(8) does. 134 1354347ef60501f: 136 The powerd(8) utility is now enabled in /etc/rc.conf by default on 137 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 138 This prevents the CPU clock from running slow all the time. 139 1400b49e504a32d: 141 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 142 to allow unmaintained jail managers like ezjail to make use of this 143 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 144 config to jail_${jailname}_zfs_dataset. 145 146e0dfe185cbca: 147 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 148 jail. 149 15061174ad88e33: 151 newsyslog(8) now supports specifying a global compression method directly 152 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 153 to behave like the corresponding option was passed to the newly added 154 '-c' option. For example: 155 156 <compress> none 157 158906748d208d3: 159 newsyslog(8) now accepts a new option, '-c' which overrides all historical 160 compression flags by treating their meaning as "treat the file as compressible" 161 rather than "compress the file with that specific method." 162 163 The following choices are available: 164 * none: Do not compress, regardless of flag. 165 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 166 * bzip2, xz, zstd, gzip: apply the specified compression method. 167 168 We plan to change the default to 'none' in FreeBSD 15.0. 169 1701a878807006c: 171 This commit added some statistics collection to the NFS-over-TLS 172 code in the NFS server so that sysadmins can moditor usage. 173 The statistics are available via the kern.rpc.tls.* sysctls. 174 1757c5146da1286: 176 Mountd has been modified to use strunvis(3) to decode directory 177 names in exports(5) file(s). This allows special characters, 178 such as blanks, to be embedded in the directory name(s). 179 "vis -M" may be used to encode such directory name(s). 180 181c5359e2af5ab: 182 bhyve(8) has a new network backend, "slirp", which makes use of the 183 libslirp package to provide a userspace network stack. This backend 184 makes it possible to access the guest network from the host without 185 requiring any extra network configuration on the host. 186 187bb830e346bd5: 188 Set the IUTF8 flag by default in tty(4). 189 190 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 191 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 192 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 193 default. 194 195ff01d71e48d4: 196 dialog(1) has been replaced by bsddialog(1) 197 19841582f28ddf7: 199 FreeBSD 15.0 will not include support for 32-bit platforms. 200 However, 64-bit systems will still be able to run older 32-bit 201 binaries. 202 203 Support for executing 32-bit binaries on 64-bit platforms via 204 COMPAT_FREEBSD32 will remain supported for at least the 205 stable/15 and stable/16 branches. 206 207 Support for compiling individual 32-bit applications via 208 `cc -m32` will also be supported for at least the stable/15 209 branch which includes suitable headers in /usr/include and 210 libraries in /usr/lib32. 211 212 Support for 32-bit platforms in ports for 15.0 and later 213 releases is also deprecated, and these future releases may not 214 include binary packages for 32-bit platforms or support for 215 building 32-bit applications from ports. 216 217 stable/14 and earlier branches will retain existing 32-bit 218 kernel and world support. Ports will retain existing support 219 for building ports and packages for 32-bit systems on stable/14 220 and earlier branches as long as those branches are supported 221 by the ports system. However, all 32-bit platforms are Tier-2 222 or Tier-3 and support for individual ports should be expected 223 to degrade as upstreams deprecate 32-bit platforms. 224 225 With the current support schedule, stable/14 will be EOLed 5 226 years after the release of 14.0. The EOL of stable/14 would 227 mark the end of support for 32-bit platforms including source 228 releases, pre-built packages, and support for building 229 applications from ports. Given an estimated release date of 230 October 2023 for 14.0, support for 32-bit platforms would end 231 in October 2028. 232 233 The project may choose to alter this approach when 15.0 is 234 released by extending some level of 32-bit support for one or 235 more platforms in 15.0 or later. Users should use the 236 stable/14 branch to migrate off of 32-bit platforms. 237
