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 13b2f7c53430c3: 14 Kernel TLS is now enabled by default in kernels including KTLS 15 support. KTLS is included in GENERIC kernels for aarch64, 16 amd64, powerpc64, and powerpc64le. 17 18f57efe95cc25: 19 New mididump(1) utility which dumps MIDI 1.0 events in real time. 20 21ddfc6f84f242: 22 Update unicode to 16.0.0 and CLDR to 45.0.0. 23 24b22be3bbb2de: 25 Basic Cloudinit images no longer generate RSA host keys by default for 26 SSH. 27 28000000000000: 29 RSA host keys for SSH are deprecated and will no longer be generated 30 by default in FreeBSD 16. 31 320aabcd75dbc2: 33 EC2 AMIs no longer generate RSA host keys by default for SSH. RSA 34 host key generation can be re-enabled by setting sshd_rsa_enable="YES" 35 in /etc/rc.conf if it is necessary to support very old SSH clients. 36 37a1da7dc1cdad: 38 The SO_SPLICE socket option was added. It allows TCP connections to 39 be spliced together, enabling proxy-like functionality without the 40 need to copy data in and out of user memory. 41 42fc12c191c087: 43 grep(1) no longer follows symbolic links by default for 44 recursive searches. This matches the documented behavior in 45 the manual page. 46 47e962b37bf0ff: 48 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 49 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 50 This is incompatible with some boot ROMs, particularly outdated builds 51 of edk2-bhyve. To restore the old behavior, add 52 "pci.enable_bars='true'" to your bhyve configuration. 53 54 Note in particular that the uefi-edk2-bhyve package has been renamed 55 to edk2-bhyve. 56 5743caa2e805c2: 58 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 59 deprecated. Use the top-level "bootrom" and "bootvars" options 60 instead. 61 62822ca3276345: 63 byacc was updated to 20240109. 64 6521817992b331: 66 ncurses was updated to 6.5. 67 681687d77197c0: 69 Filesystem manual pages have been moved to section four. 70 Please check ports you are maintaining for crossreferences. 71 728aac90f18aef: 73 new MAC/do policy and mdo(1) utility which enables a user to 74 become another user without the requirement of setuid root. 75 767398d1ece5cf: 77 hw.snd.version is removed. 78 79a15f7c96a276,a8089ea5aee5: 80 NVMe over Fabrics controller. The nvmft(4) kernel module adds 81 a new frontend to the CAM target layer which exports ctl(4) 82 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 83 is responsible for accepting incoming connection requests and 84 handing off connected queue pairs to nvmft(4). 85 86a1eda74167b5,1058c12197ab: 87 NVMe over Fabrics host. New commands added to nvmecontrol(8) 88 to establish connections to remote controllers. Once 89 connections are established they are handed off to the nvmf(4) 90 kernel module which creates nvmeX devices and exports remote 91 namespaces as nda(4) disks. 92 9325723d66369f: 94 As a side-effect of retiring the unit.* code in sound(4), the 95 hw.snd.maxunit loader(8) tunable is also retired. 96 97eeb04a736cb9: 98 date(1) now supports nanoseconds. For example: 99 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 100 `date +%N` prints "415050400". 101 1026d5ce2bb6344: 103 The default value of the nfs_reserved_port_only rc.conf(5) setting has 104 changed. The FreeBSD NFS server now requires the source port of 105 requests to be in the privileged port range (i.e., <= 1023), which 106 generally requires the client to have elevated privileges on their local 107 system. The previous behavior can be restored by setting 108 nfs_reserved_port_only=NO in rc.conf. 109 110aea973501b19: 111 ktrace(2) will now record detailed information about capability mode 112 violations. The kdump(1) utility has been updated to display such 113 information. 114 115f32a6403d346: 116 One True Awk updated to 2nd Edition. See https://awk.dev for details 117 on the additions. Unicode and CSVs (Comma Separated Values) are now 118 supported. 119 120fe86d923f83f: 121 usbconfig(8) now reads the descriptions of the usb vendor and products 122 from usb.ids when available, similarly to what pciconf(8) does. 123 1244347ef60501f: 125 The powerd(8) utility is now enabled in /etc/rc.conf by default on 126 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 127 This prevents the CPU clock from running slow all the time. 128 1290b49e504a32d: 130 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 131 to allow unmaintained jail managers like ezjail to make use of this 132 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 133 config to jail_${jailname}_zfs_dataset. 134 135e0dfe185cbca: 136 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 137 jail. 138 13961174ad88e33: 140 newsyslog(8) now supports specifying a global compression method directly 141 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 142 to behave like the corresponding option was passed to the newly added 143 '-c' option. For example: 144 145 <compress> none 146 147906748d208d3: 148 newsyslog(8) now accepts a new option, '-c' which overrides all historical 149 compression flags by treating their meaning as "treat the file as compressible" 150 rather than "compress the file with that specific method." 151 152 The following choices are available: 153 * none: Do not compress, regardless of flag. 154 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 155 * bzip2, xz, zstd, gzip: apply the specified compression method. 156 157 We plan to change the default to 'none' in FreeBSD 15.0. 158 1591a878807006c: 160 This commit added some statistics collection to the NFS-over-TLS 161 code in the NFS server so that sysadmins can moditor usage. 162 The statistics are available via the kern.rpc.tls.* sysctls. 163 1647c5146da1286: 165 Mountd has been modified to use strunvis(3) to decode directory 166 names in exports(5) file(s). This allows special characters, 167 such as blanks, to be embedded in the directory name(s). 168 "vis -M" may be used to encode such directory name(s). 169 170c5359e2af5ab: 171 bhyve(8) has a new network backend, "slirp", which makes use of the 172 libslirp package to provide a userspace network stack. This backend 173 makes it possible to access the guest network from the host without 174 requiring any extra network configuration on the host. 175 176bb830e346bd5: 177 Set the IUTF8 flag by default in tty(4). 178 179 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 180 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 181 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 182 default. 183 184ff01d71e48d4: 185 dialog(1) has been replaced by bsddialog(1) 186 18741582f28ddf7: 188 FreeBSD 15.0 will not include support for 32-bit platforms. 189 However, 64-bit systems will still be able to run older 32-bit 190 binaries. 191 192 Support for executing 32-bit binaries on 64-bit platforms via 193 COMPAT_FREEBSD32 will remain supported for at least the 194 stable/15 and stable/16 branches. 195 196 Support for compiling individual 32-bit applications via 197 `cc -m32` will also be supported for at least the stable/15 198 branch which includes suitable headers in /usr/include and 199 libraries in /usr/lib32. 200 201 Support for 32-bit platforms in ports for 15.0 and later 202 releases is also deprecated, and these future releases may not 203 include binary packages for 32-bit platforms or support for 204 building 32-bit applications from ports. 205 206 stable/14 and earlier branches will retain existing 32-bit 207 kernel and world support. Ports will retain existing support 208 for building ports and packages for 32-bit systems on stable/14 209 and earlier branches as long as those branches are supported 210 by the ports system. However, all 32-bit platforms are Tier-2 211 or Tier-3 and support for individual ports should be expected 212 to degrade as upstreams deprecate 32-bit platforms. 213 214 With the current support schedule, stable/14 will be EOLed 5 215 years after the release of 14.0. The EOL of stable/14 would 216 mark the end of support for 32-bit platforms including source 217 releases, pre-built packages, and support for building 218 applications from ports. Given an estimated release date of 219 October 2023 for 14.0, support for 32-bit platforms would end 220 in October 2028. 221 222 The project may choose to alter this approach when 15.0 is 223 released by extending some level of 32-bit support for one or 224 more platforms in 15.0 or later. Users should use the 225 stable/14 branch to migrate off of 32-bit platforms. 226
