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 37e962b37bf0ff: 38 When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not 39 used, bhyve now assumes that the boot ROM will enable PCI BAR decoding. 40 This is incompatible with some boot ROMs, particularly outdated builds 41 of edk2-bhyve. To restore the old behavior, add 42 "pci.enable_bars='true'" to your bhyve configuration. 43 44 Note in particular that the uefi-edk2-bhyve package has been renamed 45 to edk2-bhyve. 46 4743caa2e805c2: 48 amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are 49 deprecated. Use the top-level "bootrom" and "bootvars" options 50 instead. 51 52822ca3276345: 53 byacc was updated to 20240109. 54 5521817992b331: 56 ncurses was updated to 6.5. 57 581687d77197c0: 59 Filesystem manual pages have been moved to section four. 60 Please check ports you are maintaining for crossreferences. 61 628aac90f18aef: 63 new MAC/do policy and mdo(1) utility which enables a user to 64 become another user without the requirement of setuid root. 65 667398d1ece5cf: 67 hw.snd.version is removed. 68 69a15f7c96a276,a8089ea5aee5: 70 NVMe over Fabrics controller. The nvmft(4) kernel module adds 71 a new frontend to the CAM target layer which exports ctl(4) 72 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 73 is responsible for accepting incoming connection requests and 74 handing off connected queue pairs to nvmft(4). 75 76a1eda74167b5,1058c12197ab: 77 NVMe over Fabrics host. New commands added to nvmecontrol(8) 78 to establish connections to remote controllers. Once 79 connections are established they are handed off to the nvmf(4) 80 kernel module which creates nvmeX devices and exports remote 81 namespaces as nda(4) disks. 82 8325723d66369f: 84 As a side-effect of retiring the unit.* code in sound(4), the 85 hw.snd.maxunit loader(8) tunable is also retired. 86 87eeb04a736cb9: 88 date(1) now supports nanoseconds. For example: 89 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 90 `date +%N` prints "415050400". 91 926d5ce2bb6344: 93 The default value of the nfs_reserved_port_only rc.conf(5) setting has 94 changed. The FreeBSD NFS server now requires the source port of 95 requests to be in the privileged port range (i.e., <= 1023), which 96 generally requires the client to have elevated privileges on their local 97 system. The previous behavior can be restored by setting 98 nfs_reserved_port_only=NO in rc.conf. 99 100aea973501b19: 101 ktrace(2) will now record detailed information about capability mode 102 violations. The kdump(1) utility has been updated to display such 103 information. 104 105f32a6403d346: 106 One True Awk updated to 2nd Edition. See https://awk.dev for details 107 on the additions. Unicode and CSVs (Comma Separated Values) are now 108 supported. 109 110fe86d923f83f: 111 usbconfig(8) now reads the descriptions of the usb vendor and products 112 from usb.ids when available, similarly to what pciconf(8) does. 113 1144347ef60501f: 115 The powerd(8) utility is now enabled in /etc/rc.conf by default on 116 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 117 This prevents the CPU clock from running slow all the time. 118 1190b49e504a32d: 120 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 121 to allow unmaintained jail managers like ezjail to make use of this 122 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 123 config to jail_${jailname}_zfs_dataset. 124 125e0dfe185cbca: 126 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 127 jail. 128 12961174ad88e33: 130 newsyslog(8) now supports specifying a global compression method directly 131 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 132 to behave like the corresponding option was passed to the newly added 133 '-c' option. For example: 134 135 <compress> none 136 137906748d208d3: 138 newsyslog(8) now accepts a new option, '-c' which overrides all historical 139 compression flags by treating their meaning as "treat the file as compressible" 140 rather than "compress the file with that specific method." 141 142 The following choices are available: 143 * none: Do not compress, regardless of flag. 144 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 145 * bzip2, xz, zstd, gzip: apply the specified compression method. 146 147 We plan to change the default to 'none' in FreeBSD 15.0. 148 1491a878807006c: 150 This commit added some statistics collection to the NFS-over-TLS 151 code in the NFS server so that sysadmins can moditor usage. 152 The statistics are available via the kern.rpc.tls.* sysctls. 153 1547c5146da1286: 155 Mountd has been modified to use strunvis(3) to decode directory 156 names in exports(5) file(s). This allows special characters, 157 such as blanks, to be embedded in the directory name(s). 158 "vis -M" may be used to encode such directory name(s). 159 160c5359e2af5ab: 161 bhyve(8) has a new network backend, "slirp", which makes use of the 162 libslirp package to provide a userspace network stack. This backend 163 makes it possible to access the guest network from the host without 164 requiring any extra network configuration on the host. 165 166bb830e346bd5: 167 Set the IUTF8 flag by default in tty(4). 168 169 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 170 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 171 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 172 default. 173 174ff01d71e48d4: 175 dialog(1) has been replaced by bsddialog(1) 176 17741582f28ddf7: 178 FreeBSD 15.0 will not include support for 32-bit platforms. 179 However, 64-bit systems will still be able to run older 32-bit 180 binaries. 181 182 Support for executing 32-bit binaries on 64-bit platforms via 183 COMPAT_FREEBSD32 will remain supported for at least the 184 stable/15 and stable/16 branches. 185 186 Support for compiling individual 32-bit applications via 187 `cc -m32` will also be supported for at least the stable/15 188 branch which includes suitable headers in /usr/include and 189 libraries in /usr/lib32. 190 191 Support for 32-bit platforms in ports for 15.0 and later 192 releases is also deprecated, and these future releases may not 193 include binary packages for 32-bit platforms or support for 194 building 32-bit applications from ports. 195 196 stable/14 and earlier branches will retain existing 32-bit 197 kernel and world support. Ports will retain existing support 198 for building ports and packages for 32-bit systems on stable/14 199 and earlier branches as long as those branches are supported 200 by the ports system. However, all 32-bit platforms are Tier-2 201 or Tier-3 and support for individual ports should be expected 202 to degrade as upstreams deprecate 32-bit platforms. 203 204 With the current support schedule, stable/14 will be EOLed 5 205 years after the release of 14.0. The EOL of stable/14 would 206 mark the end of support for 32-bit platforms including source 207 releases, pre-built packages, and support for building 208 applications from ports. Given an estimated release date of 209 October 2023 for 14.0, support for 32-bit platforms would end 210 in October 2028. 211 212 The project may choose to alter this approach when 15.0 is 213 released by extending some level of 32-bit support for one or 214 more platforms in 15.0 or later. Users should use the 215 stable/14 branch to migrate off of 32-bit platforms. 216
