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 13f57efe95cc25: 14 New mididump(1) utility which dumps MIDI 1.0 events in real time. 15 16ddfc6f84f242: 17 Update unicode to 16.0.0 and CLDR to 45.0.0. 18 19b22be3bbb2de: 20 Basic Cloudinit images no longer generate RSA host keys by default for 21 SSH. 22 23000000000000: 24 RSA host keys for SSH are deprecated and will no longer be generated 25 by default in FreeBSD 16. 26 270aabcd75dbc2: 28 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 29 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 30 in /etc/rc.conf if it is necessary to support very old SSH clients. 31 32a1da7dc1cdad: 33 The SO_SPLICE socket option was added. It allows TCP connections to 34 be spliced together, enabling proxy-like functionality without the 35 need to copy data in and out of user memory. 36 37fc12c191c087: 38 grep(1) no longer follows symbolic links by default for 39 recursive searches. This matches the documented behavior in 40 the manual page. 41 42e962b37bf0ff: 43 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 44 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 45 This is incompatible with some boot ROMs, particularly outdated builds 46 of edk2-bhyve. To restore the old behavior, add 47 "pci.enable_bars='true'" to your bhyve configuration. 48 49 Note in particular that the uefi-edk2-bhyve package has been renamed 50 to edk2-bhyve. 51 5243caa2e805c2: 53 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 54 deprecated. Use the top-level "bootrom" and "bootvars" options 55 instead. 56 57822ca3276345: 58 byacc was updated to 20240109. 59 6021817992b331: 61 ncurses was updated to 6.5. 62 631687d77197c0: 64 Filesystem manual pages have been moved to section four. 65 Please check ports you are maintaining for crossreferences. 66 678aac90f18aef: 68 new MAC/do policy and mdo(1) utility which enables a user to 69 become another user without the requirement of setuid root. 70 717398d1ece5cf: 72 hw.snd.version is removed. 73 74a15f7c96a276,a8089ea5aee5: 75 NVMe over Fabrics controller. The nvmft(4) kernel module adds 76 a new frontend to the CAM target layer which exports ctl(4) 77 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 78 is responsible for accepting incoming connection requests and 79 handing off connected queue pairs to nvmft(4). 80 81a1eda74167b5,1058c12197ab: 82 NVMe over Fabrics host. New commands added to nvmecontrol(8) 83 to establish connections to remote controllers. Once 84 connections are established they are handed off to the nvmf(4) 85 kernel module which creates nvmeX devices and exports remote 86 namespaces as nda(4) disks. 87 8825723d66369f: 89 As a side-effect of retiring the unit.* code in sound(4), the 90 hw.snd.maxunit loader(8) tunable is also retired. 91 92eeb04a736cb9: 93 date(1) now supports nanoseconds. For example: 94 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 95 `date +%N` prints "415050400". 96 976d5ce2bb6344: 98 The default value of the nfs_reserved_port_only rc.conf(5) setting has 99 changed. The FreeBSD NFS server now requires the source port of 100 requests to be in the privileged port range (i.e., <= 1023), which 101 generally requires the client to have elevated privileges on their local 102 system. The previous behavior can be restored by setting 103 nfs_reserved_port_only=NO in rc.conf. 104 105aea973501b19: 106 ktrace(2) will now record detailed information about capability mode 107 violations. The kdump(1) utility has been updated to display such 108 information. 109 110f32a6403d346: 111 One True Awk updated to 2nd Edition. See https://awk.dev for details 112 on the additions. Unicode and CSVs (Comma Separated Values) are now 113 supported. 114 115fe86d923f83f: 116 usbconfig(8) now reads the descriptions of the usb vendor and products 117 from usb.ids when available, similarly to what pciconf(8) does. 118 1194347ef60501f: 120 The powerd(8) utility is now enabled in /etc/rc.conf by default on 121 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 122 This prevents the CPU clock from running slow all the time. 123 1240b49e504a32d: 125 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 126 to allow unmaintained jail managers like ezjail to make use of this 127 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 128 config to jail_${jailname}_zfs_dataset. 129 130e0dfe185cbca: 131 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 132 jail. 133 13461174ad88e33: 135 newsyslog(8) now supports specifying a global compression method directly 136 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 137 to behave like the corresponding option was passed to the newly added 138 '-c' option. For example: 139 140 <compress> none 141 142906748d208d3: 143 newsyslog(8) now accepts a new option, '-c' which overrides all historical 144 compression flags by treating their meaning as "treat the file as compressible" 145 rather than "compress the file with that specific method." 146 147 The following choices are available: 148 * none: Do not compress, regardless of flag. 149 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 150 * bzip2, xz, zstd, gzip: apply the specified compression method. 151 152 We plan to change the default to 'none' in FreeBSD 15.0. 153 1541a878807006c: 155 This commit added some statistics collection to the NFS-over-TLS 156 code in the NFS server so that sysadmins can moditor usage. 157 The statistics are available via the kern.rpc.tls.* sysctls. 158 1597c5146da1286: 160 Mountd has been modified to use strunvis(3) to decode directory 161 names in exports(5) file(s). This allows special characters, 162 such as blanks, to be embedded in the directory name(s). 163 "vis -M" may be used to encode such directory name(s). 164 165c5359e2af5ab: 166 bhyve(8) has a new network backend, "slirp", which makes use of the 167 libslirp package to provide a userspace network stack. This backend 168 makes it possible to access the guest network from the host without 169 requiring any extra network configuration on the host. 170 171bb830e346bd5: 172 Set the IUTF8 flag by default in tty(4). 173 174 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 175 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 176 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 177 default. 178 179ff01d71e48d4: 180 dialog(1) has been replaced by bsddialog(1) 181 18241582f28ddf7: 183 FreeBSD 15.0 will not include support for 32-bit platforms. 184 However, 64-bit systems will still be able to run older 32-bit 185 binaries. 186 187 Support for executing 32-bit binaries on 64-bit platforms via 188 COMPAT_FREEBSD32 will remain supported for at least the 189 stable/15 and stable/16 branches. 190 191 Support for compiling individual 32-bit applications via 192 `cc -m32` will also be supported for at least the stable/15 193 branch which includes suitable headers in /usr/include and 194 libraries in /usr/lib32. 195 196 Support for 32-bit platforms in ports for 15.0 and later 197 releases is also deprecated, and these future releases may not 198 include binary packages for 32-bit platforms or support for 199 building 32-bit applications from ports. 200 201 stable/14 and earlier branches will retain existing 32-bit 202 kernel and world support. Ports will retain existing support 203 for building ports and packages for 32-bit systems on stable/14 204 and earlier branches as long as those branches are supported 205 by the ports system. However, all 32-bit platforms are Tier-2 206 or Tier-3 and support for individual ports should be expected 207 to degrade as upstreams deprecate 32-bit platforms. 208 209 With the current support schedule, stable/14 will be EOLed 5 210 years after the release of 14.0. The EOL of stable/14 would 211 mark the end of support for 32-bit platforms including source 212 releases, pre-built packages, and support for building 213 applications from ports. Given an estimated release date of 214 October 2023 for 14.0, support for 32-bit platforms would end 215 in October 2028. 216 217 The project may choose to alter this approach when 15.0 is 218 released by extending some level of 32-bit support for one or 219 more platforms in 15.0 or later. Users should use the 220 stable/14 branch to migrate off of 32-bit platforms. 221
