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 13 14822ca3276345: 15 byacc was updated to 20240109. 16 1721817992b331: 18 ncurses was updated to 6.5. 19 208aac90f18aef: 21 new MAC/do policy and mdo(1) utility which enables a user to 22 become another user without the requirement of setuid root. 23 247398d1ece5cf: 25 hw.snd.version is removed. 26 27a15f7c96a276,a8089ea5aee5: 28 NVMe over Fabrics controller. The nvmft(4) kernel module adds 29 a new frontend to the CAM target layer which exports ctl(4) 30 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 31 is responsible for accepting incoming connection requests and 32 handing off connected queue pairs to nvmft(4). 33 34a1eda74167b5,1058c12197ab: 35 NVMe over Fabrics host. New commands added to nvmecontrol(8) 36 to establish connections to remote controllers. Once 37 connections are established they are handed off to the nvmf(4) 38 kernel module which creates nvmeX devices and exports remote 39 namespaces as nda(4) disks. 40 4125723d66369f: 42 As a side-effect of retiring the unit.* code in sound(4), the 43 hw.snd.maxunit loader(8) tunable is also retired. 44 45eeb04a736cb9: 46 date(1) now supports nanoseconds. For example: 47 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 48 `date +%N` prints "415050400". 49 506d5ce2bb6344: 51 The default value of the nfs_reserved_port_only rc.conf(5) setting has 52 changed. The FreeBSD NFS server now requires the source port of 53 requests to be in the privileged port range (i.e., <= 1023), which 54 generally requires the client to have elevated privileges on their local 55 system. The previous behavior can be restored by setting 56 nfs_reserved_port_only=NO in rc.conf. 57 58aea973501b19: 59 ktrace(2) will now record detailed information about capability mode 60 violations. The kdump(1) utility has been updated to display such 61 information. 62 63f32a6403d346: 64 One True Awk updated to 2nd Edition. See https://awk.dev for details 65 on the additions. Unicode and CSVs (Comma Separated Values) are now 66 supported. 67 68fe86d923f83f: 69 usbconfig(8) now reads the descriptions of the usb vendor and products 70 from usb.ids when available, similarly to what pciconf(8) does. 71 724347ef60501f: 73 The powerd(8) utility is now enabled in /etc/rc.conf by default on 74 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 75 This prevents the CPU clock from running slow all the time. 76 770b49e504a32d: 78 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 79 to allow unmaintained jail managers like ezjail to make use of this 80 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 81 config to jail_${jailname}_zfs_dataset. 82 83e0dfe185cbca: 84 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 85 jail. 86 8761174ad88e33: 88 newsyslog(8) now supports specifying a global compression method directly 89 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 90 to behave like the corresponding option was passed to the newly added 91 '-c' option. For example: 92 93 <compress> none 94 95906748d208d3: 96 newsyslog(8) now accepts a new option, '-c' which overrides all historical 97 compression flags by treating their meaning as "treat the file as compressible" 98 rather than "compress the file with that specific method." 99 100 The following choices are available: 101 * none: Do not compress, regardless of flag. 102 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 103 * bzip2, xz, zstd, gzip: apply the specified compression method. 104 105 We plan to change the default to 'none' in FreeBSD 15.0. 106 1071a878807006c: 108 This commit added some statistics collection to the NFS-over-TLS 109 code in the NFS server so that sysadmins can moditor usage. 110 The statistics are available via the kern.rpc.tls.* sysctls. 111 1127c5146da1286: 113 Mountd has been modified to use strunvis(3) to decode directory 114 names in exports(5) file(s). This allows special characters, 115 such as blanks, to be embedded in the directory name(s). 116 "vis -M" may be used to encode such directory name(s). 117 118c5359e2af5ab: 119 bhyve(8) has a new network backend, "slirp", which makes use of the 120 libslirp package to provide a userspace network stack. This backend 121 makes it possible to access the guest network from the host without 122 requiring any extra network configuration on the host. 123 124bb830e346bd5: 125 Set the IUTF8 flag by default in tty(4). 126 127 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 128 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 129 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 130 default. 131 132ff01d71e48d4: 133 dialog(1) has been replaced by bsddialog(1) 134 13541582f28ddf7: 136 FreeBSD 15.0 will not include support for 32-bit platforms. 137 However, 64-bit systems will still be able to run older 32-bit 138 binaries. 139 140 Support for executing 32-bit binaries on 64-bit platforms via 141 COMPAT_FREEBSD32 will remain supported for at least the 142 stable/15 and stable/16 branches. 143 144 Support for compiling individual 32-bit applications via 145 `cc -m32` will also be supported for at least the stable/15 146 branch which includes suitable headers in /usr/include and 147 libraries in /usr/lib32. 148 149 Support for 32-bit platforms in ports for 15.0 and later 150 releases is also deprecated, and these future releases may not 151 include binary packages for 32-bit platforms or support for 152 building 32-bit applications from ports. 153 154 stable/14 and earlier branches will retain existing 32-bit 155 kernel and world support. Ports will retain existing support 156 for building ports and packages for 32-bit systems on stable/14 157 and earlier branches as long as those branches are supported 158 by the ports system. However, all 32-bit platforms are Tier-2 159 or Tier-3 and support for individual ports should be expected 160 to degrade as upstreams deprecate 32-bit platforms. 161 162 With the current support schedule, stable/14 will be EOLed 5 163 years after the release of 14.0. The EOL of stable/14 would 164 mark the end of support for 32-bit platforms including source 165 releases, pre-built packages, and support for building 166 applications from ports. Given an estimated release date of 167 October 2023 for 14.0, support for 32-bit platforms would end 168 in October 2028. 169 170 The project may choose to alter this approach when 15.0 is 171 released by extending some level of 32-bit support for one or 172 more platforms in 15.0 or later. Users should use the 173 stable/14 branch to migrate off of 32-bit platforms. 174
