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 130e8a36a2ab12: 14 Add a new NFS mount option called "mountport" that may be used 15 to specify the port# for the NFS server's Mount protocol. 16 This permits a NFSv3 mount to be done without running rpcbind(8). 17 18b2f7c53430c3: 19 Kernel TLS is now enabled by default in kernels including KTLS 20 support. KTLS is included in GENERIC kernels for aarch64, 21 amd64, powerpc64, and powerpc64le. 22 23f57efe95cc25: 24 New mididump(1) utility which dumps MIDI 1.0 events in real time. 25 26ddfc6f84f242: 27 Update unicode to 16.0.0 and CLDR to 45.0.0. 28 29b22be3bbb2de: 30 Basic Cloudinit images no longer generate RSA host keys by default for 31 SSH. 32 33000000000000: 34 RSA host keys for SSH are deprecated and will no longer be generated 35 by default in FreeBSD 16. 36 370aabcd75dbc2: 38 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 39 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 40 in /etc/rc.conf if it is necessary to support very old SSH clients. 41 42a1da7dc1cdad: 43 The SO_SPLICE socket option was added. It allows TCP connections to 44 be spliced together, enabling proxy-like functionality without the 45 need to copy data in and out of user memory. 46 47fc12c191c087: 48 grep(1) no longer follows symbolic links by default for 49 recursive searches. This matches the documented behavior in 50 the manual page. 51 52e962b37bf0ff: 53 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 54 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 55 This is incompatible with some boot ROMs, particularly outdated builds 56 of edk2-bhyve. To restore the old behavior, add 57 "pci.enable_bars='true'" to your bhyve configuration. 58 59 Note in particular that the uefi-edk2-bhyve package has been renamed 60 to edk2-bhyve. 61 6243caa2e805c2: 63 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 64 deprecated. Use the top-level "bootrom" and "bootvars" options 65 instead. 66 67822ca3276345: 68 byacc was updated to 20240109. 69 7021817992b331: 71 ncurses was updated to 6.5. 72 731687d77197c0: 74 Filesystem manual pages have been moved to section four. 75 Please check ports you are maintaining for crossreferences. 76 778aac90f18aef: 78 new MAC/do policy and mdo(1) utility which enables a user to 79 become another user without the requirement of setuid root. 80 817398d1ece5cf: 82 hw.snd.version is removed. 83 84a15f7c96a276,a8089ea5aee5: 85 NVMe over Fabrics controller. The nvmft(4) kernel module adds 86 a new frontend to the CAM target layer which exports ctl(4) 87 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 88 is responsible for accepting incoming connection requests and 89 handing off connected queue pairs to nvmft(4). 90 91a1eda74167b5,1058c12197ab: 92 NVMe over Fabrics host. New commands added to nvmecontrol(8) 93 to establish connections to remote controllers. Once 94 connections are established they are handed off to the nvmf(4) 95 kernel module which creates nvmeX devices and exports remote 96 namespaces as nda(4) disks. 97 9825723d66369f: 99 As a side-effect of retiring the unit.* code in sound(4), the 100 hw.snd.maxunit loader(8) tunable is also retired. 101 102eeb04a736cb9: 103 date(1) now supports nanoseconds. For example: 104 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 105 `date +%N` prints "415050400". 106 1076d5ce2bb6344: 108 The default value of the nfs_reserved_port_only rc.conf(5) setting has 109 changed. The FreeBSD NFS server now requires the source port of 110 requests to be in the privileged port range (i.e., <= 1023), which 111 generally requires the client to have elevated privileges on their local 112 system. The previous behavior can be restored by setting 113 nfs_reserved_port_only=NO in rc.conf. 114 115aea973501b19: 116 ktrace(2) will now record detailed information about capability mode 117 violations. The kdump(1) utility has been updated to display such 118 information. 119 120f32a6403d346: 121 One True Awk updated to 2nd Edition. See https://awk.dev for details 122 on the additions. Unicode and CSVs (Comma Separated Values) are now 123 supported. 124 125fe86d923f83f: 126 usbconfig(8) now reads the descriptions of the usb vendor and products 127 from usb.ids when available, similarly to what pciconf(8) does. 128 1294347ef60501f: 130 The powerd(8) utility is now enabled in /etc/rc.conf by default on 131 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 132 This prevents the CPU clock from running slow all the time. 133 1340b49e504a32d: 135 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 136 to allow unmaintained jail managers like ezjail to make use of this 137 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 138 config to jail_${jailname}_zfs_dataset. 139 140e0dfe185cbca: 141 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 142 jail. 143 14461174ad88e33: 145 newsyslog(8) now supports specifying a global compression method directly 146 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 147 to behave like the corresponding option was passed to the newly added 148 '-c' option. For example: 149 150 <compress> none 151 152906748d208d3: 153 newsyslog(8) now accepts a new option, '-c' which overrides all historical 154 compression flags by treating their meaning as "treat the file as compressible" 155 rather than "compress the file with that specific method." 156 157 The following choices are available: 158 * none: Do not compress, regardless of flag. 159 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 160 * bzip2, xz, zstd, gzip: apply the specified compression method. 161 162 We plan to change the default to 'none' in FreeBSD 15.0. 163 1641a878807006c: 165 This commit added some statistics collection to the NFS-over-TLS 166 code in the NFS server so that sysadmins can moditor usage. 167 The statistics are available via the kern.rpc.tls.* sysctls. 168 1697c5146da1286: 170 Mountd has been modified to use strunvis(3) to decode directory 171 names in exports(5) file(s). This allows special characters, 172 such as blanks, to be embedded in the directory name(s). 173 "vis -M" may be used to encode such directory name(s). 174 175c5359e2af5ab: 176 bhyve(8) has a new network backend, "slirp", which makes use of the 177 libslirp package to provide a userspace network stack. This backend 178 makes it possible to access the guest network from the host without 179 requiring any extra network configuration on the host. 180 181bb830e346bd5: 182 Set the IUTF8 flag by default in tty(4). 183 184 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 185 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 186 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 187 default. 188 189ff01d71e48d4: 190 dialog(1) has been replaced by bsddialog(1) 191 19241582f28ddf7: 193 FreeBSD 15.0 will not include support for 32-bit platforms. 194 However, 64-bit systems will still be able to run older 32-bit 195 binaries. 196 197 Support for executing 32-bit binaries on 64-bit platforms via 198 COMPAT_FREEBSD32 will remain supported for at least the 199 stable/15 and stable/16 branches. 200 201 Support for compiling individual 32-bit applications via 202 `cc -m32` will also be supported for at least the stable/15 203 branch which includes suitable headers in /usr/include and 204 libraries in /usr/lib32. 205 206 Support for 32-bit platforms in ports for 15.0 and later 207 releases is also deprecated, and these future releases may not 208 include binary packages for 32-bit platforms or support for 209 building 32-bit applications from ports. 210 211 stable/14 and earlier branches will retain existing 32-bit 212 kernel and world support. Ports will retain existing support 213 for building ports and packages for 32-bit systems on stable/14 214 and earlier branches as long as those branches are supported 215 by the ports system. However, all 32-bit platforms are Tier-2 216 or Tier-3 and support for individual ports should be expected 217 to degrade as upstreams deprecate 32-bit platforms. 218 219 With the current support schedule, stable/14 will be EOLed 5 220 years after the release of 14.0. The EOL of stable/14 would 221 mark the end of support for 32-bit platforms including source 222 releases, pre-built packages, and support for building 223 applications from ports. Given an estimated release date of 224 October 2023 for 14.0, support for 32-bit platforms would end 225 in October 2028. 226 227 The project may choose to alter this approach when 15.0 is 228 released by extending some level of 32-bit support for one or 229 more platforms in 15.0 or later. Users should use the 230 stable/14 branch to migrate off of 32-bit platforms. 231
