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 13ddfc6f84f242: 14 Update unicode to 16.0.0 and CLDR to 45.0.0. 15 16b22be3bbb2de: 17 Basic Cloudinit images no longer generate RSA host keys by default for 18 SSH. 19 20000000000000: 21 RSA host keys for SSH are deprecated and will no longer be generated 22 by default in FreeBSD 16. 23 240aabcd75dbc2: 25 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 26 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 27 in /etc/rc.conf if it is necessary to support very old SSH clients. 28 29a1da7dc1cdad: 30 The SO_SPLICE socket option was added. It allows TCP connections to 31 be spliced together, enabling proxy-like functionality without the 32 need to copy data in and out of user memory. 33 34e962b37bf0ff: 35 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 36 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 37 This is incompatible with some boot ROMs, particularly outdated builds 38 of edk2-bhyve. To restore the old behavior, add 39 "pci.enable_bars='true'" to your bhyve configuration. 40 41 Note in particular that the uefi-edk2-bhyve package has been renamed 42 to edk2-bhyve. 43 4443caa2e805c2: 45 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 46 deprecated. Use the top-level "bootrom" and "bootvars" options 47 instead. 48 49822ca3276345: 50 byacc was updated to 20240109. 51 5221817992b331: 53 ncurses was updated to 6.5. 54 551687d77197c0: 56 Filesystem manual pages have been moved to section four. 57 Please check ports you are maintaining for crossreferences. 58 598aac90f18aef: 60 new MAC/do policy and mdo(1) utility which enables a user to 61 become another user without the requirement of setuid root. 62 637398d1ece5cf: 64 hw.snd.version is removed. 65 66a15f7c96a276,a8089ea5aee5: 67 NVMe over Fabrics controller. The nvmft(4) kernel module adds 68 a new frontend to the CAM target layer which exports ctl(4) 69 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 70 is responsible for accepting incoming connection requests and 71 handing off connected queue pairs to nvmft(4). 72 73a1eda74167b5,1058c12197ab: 74 NVMe over Fabrics host. New commands added to nvmecontrol(8) 75 to establish connections to remote controllers. Once 76 connections are established they are handed off to the nvmf(4) 77 kernel module which creates nvmeX devices and exports remote 78 namespaces as nda(4) disks. 79 8025723d66369f: 81 As a side-effect of retiring the unit.* code in sound(4), the 82 hw.snd.maxunit loader(8) tunable is also retired. 83 84eeb04a736cb9: 85 date(1) now supports nanoseconds. For example: 86 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 87 `date +%N` prints "415050400". 88 896d5ce2bb6344: 90 The default value of the nfs_reserved_port_only rc.conf(5) setting has 91 changed. The FreeBSD NFS server now requires the source port of 92 requests to be in the privileged port range (i.e., <= 1023), which 93 generally requires the client to have elevated privileges on their local 94 system. The previous behavior can be restored by setting 95 nfs_reserved_port_only=NO in rc.conf. 96 97aea973501b19: 98 ktrace(2) will now record detailed information about capability mode 99 violations. The kdump(1) utility has been updated to display such 100 information. 101 102f32a6403d346: 103 One True Awk updated to 2nd Edition. See https://awk.dev for details 104 on the additions. Unicode and CSVs (Comma Separated Values) are now 105 supported. 106 107fe86d923f83f: 108 usbconfig(8) now reads the descriptions of the usb vendor and products 109 from usb.ids when available, similarly to what pciconf(8) does. 110 1114347ef60501f: 112 The powerd(8) utility is now enabled in /etc/rc.conf by default on 113 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 114 This prevents the CPU clock from running slow all the time. 115 1160b49e504a32d: 117 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 118 to allow unmaintained jail managers like ezjail to make use of this 119 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 120 config to jail_${jailname}_zfs_dataset. 121 122e0dfe185cbca: 123 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 124 jail. 125 12661174ad88e33: 127 newsyslog(8) now supports specifying a global compression method directly 128 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 129 to behave like the corresponding option was passed to the newly added 130 '-c' option. For example: 131 132 <compress> none 133 134906748d208d3: 135 newsyslog(8) now accepts a new option, '-c' which overrides all historical 136 compression flags by treating their meaning as "treat the file as compressible" 137 rather than "compress the file with that specific method." 138 139 The following choices are available: 140 * none: Do not compress, regardless of flag. 141 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 142 * bzip2, xz, zstd, gzip: apply the specified compression method. 143 144 We plan to change the default to 'none' in FreeBSD 15.0. 145 1461a878807006c: 147 This commit added some statistics collection to the NFS-over-TLS 148 code in the NFS server so that sysadmins can moditor usage. 149 The statistics are available via the kern.rpc.tls.* sysctls. 150 1517c5146da1286: 152 Mountd has been modified to use strunvis(3) to decode directory 153 names in exports(5) file(s). This allows special characters, 154 such as blanks, to be embedded in the directory name(s). 155 "vis -M" may be used to encode such directory name(s). 156 157c5359e2af5ab: 158 bhyve(8) has a new network backend, "slirp", which makes use of the 159 libslirp package to provide a userspace network stack. This backend 160 makes it possible to access the guest network from the host without 161 requiring any extra network configuration on the host. 162 163bb830e346bd5: 164 Set the IUTF8 flag by default in tty(4). 165 166 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 167 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 168 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 169 default. 170 171ff01d71e48d4: 172 dialog(1) has been replaced by bsddialog(1) 173 17441582f28ddf7: 175 FreeBSD 15.0 will not include support for 32-bit platforms. 176 However, 64-bit systems will still be able to run older 32-bit 177 binaries. 178 179 Support for executing 32-bit binaries on 64-bit platforms via 180 COMPAT_FREEBSD32 will remain supported for at least the 181 stable/15 and stable/16 branches. 182 183 Support for compiling individual 32-bit applications via 184 `cc -m32` will also be supported for at least the stable/15 185 branch which includes suitable headers in /usr/include and 186 libraries in /usr/lib32. 187 188 Support for 32-bit platforms in ports for 15.0 and later 189 releases is also deprecated, and these future releases may not 190 include binary packages for 32-bit platforms or support for 191 building 32-bit applications from ports. 192 193 stable/14 and earlier branches will retain existing 32-bit 194 kernel and world support. Ports will retain existing support 195 for building ports and packages for 32-bit systems on stable/14 196 and earlier branches as long as those branches are supported 197 by the ports system. However, all 32-bit platforms are Tier-2 198 or Tier-3 and support for individual ports should be expected 199 to degrade as upstreams deprecate 32-bit platforms. 200 201 With the current support schedule, stable/14 will be EOLed 5 202 years after the release of 14.0. The EOL of stable/14 would 203 mark the end of support for 32-bit platforms including source 204 releases, pre-built packages, and support for building 205 applications from ports. Given an estimated release date of 206 October 2023 for 14.0, support for 32-bit platforms would end 207 in October 2028. 208 209 The project may choose to alter this approach when 15.0 is 210 released by extending some level of 32-bit support for one or 211 more platforms in 15.0 or later. Users should use the 212 stable/14 branch to migrate off of 32-bit platforms. 213
