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 138aac90f18aef: 14 new MAC/do policy and mdo(1) utility which enables a user to 15 become another user without the requirement of setuid root. 16 177398d1ece5cf: 18 hw.snd.version is removed. 19 20a15f7c96a276,a8089ea5aee5: 21 NVMe over Fabrics controller. The nvmft(4) kernel module adds 22 a new frontend to the CAM target layer which exports ctl(4) 23 LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon 24 is responsible for accepting incoming connection requests and 25 handing off connected queue pairs to nvmft(4). 26 27a1eda74167b5,1058c12197ab: 28 NVMe over Fabrics host. New commands added to nvmecontrol(8) 29 to establish connections to remote controllers. Once 30 connections are established they are handed off to the nvmf(4) 31 kernel module which creates nvmeX devices and exports remote 32 namespaces as nda(4) disks. 33 3425723d66369f: 35 As a side-effect of retiring the unit.* code in sound(4), the 36 hw.snd.maxunit loader(8) tunable is also retired. 37 38eeb04a736cb9: 39 date(1) now supports nanoseconds. For example: 40 `date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and 41 `date +%N` prints "415050400". 42 436d5ce2bb6344: 44 The default value of the nfs_reserved_port_only rc.conf(5) setting has 45 changed. The FreeBSD NFS server now requires the source port of 46 requests to be in the privileged port range (i.e., <= 1023), which 47 generally requires the client to have elevated privileges on their local 48 system. The previous behavior can be restored by setting 49 nfs_reserved_port_only=NO in rc.conf. 50 51aea973501b19: 52 ktrace(2) will now record detailed information about capability mode 53 violations. The kdump(1) utility has been updated to display such 54 information. 55 56f32a6403d346: 57 One True Awk updated to 2nd Edition. See https://awk.dev for details 58 on the additions. Unicode and CSVs (Comma Separated Values) are now 59 supported. 60 61fe86d923f83f: 62 usbconfig(8) now reads the descriptions of the usb vendor and products 63 from usb.ids when available, similarly to what pciconf(8) does. 64 654347ef60501f: 66 The powerd(8) utility is now enabled in /etc/rc.conf by default on 67 images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files). 68 This prevents the CPU clock from running slow all the time. 69 700b49e504a32d: 71 rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset 72 to allow unmaintained jail managers like ezjail to make use of this 73 feature (simply rename jail_${jailname}_zfs_datasets in the ezjail 74 config to jail_${jailname}_zfs_dataset. 75 76e0dfe185cbca: 77 jail(8) now support zfs.dataset to add a list of ZFS datasets to a 78 jail. 79 8061174ad88e33: 81 newsyslog(8) now supports specifying a global compression method directly 82 at the beginning of the newsyslog.conf file, which will make newsyslog(8) 83 to behave like the corresponding option was passed to the newly added 84 '-c' option. For example: 85 86 <compress> none 87 88906748d208d3: 89 newsyslog(8) now accepts a new option, '-c' which overrides all historical 90 compression flags by treating their meaning as "treat the file as compressible" 91 rather than "compress the file with that specific method." 92 93 The following choices are available: 94 * none: Do not compress, regardless of flag. 95 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip). 96 * bzip2, xz, zstd, gzip: apply the specified compression method. 97 98 We plan to change the default to 'none' in FreeBSD 15.0. 99 1001a878807006c: 101 This commit added some statistics collection to the NFS-over-TLS 102 code in the NFS server so that sysadmins can moditor usage. 103 The statistics are available via the kern.rpc.tls.* sysctls. 104 1057c5146da1286: 106 Mountd has been modified to use strunvis(3) to decode directory 107 names in exports(5) file(s). This allows special characters, 108 such as blanks, to be embedded in the directory name(s). 109 "vis -M" may be used to encode such directory name(s). 110 111c5359e2af5ab: 112 bhyve(8) has a new network backend, "slirp", which makes use of the 113 libslirp package to provide a userspace network stack. This backend 114 makes it possible to access the guest network from the host without 115 requiring any extra network configuration on the host. 116 117bb830e346bd5: 118 Set the IUTF8 flag by default in tty(4). 119 120 128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling 121 in the tty(4) driver, which is enabled by setting the new IUTF8 flag 122 through stty(1). Since the default locale is UTF-8, enable IUTF8 by 123 default. 124 125ff01d71e48d4: 126 dialog(1) has been replaced by bsddialog(1) 127 12841582f28ddf7: 129 FreeBSD 15.0 will not include support for 32-bit platforms. 130 However, 64-bit systems will still be able to run older 32-bit 131 binaries. 132 133 Support for executing 32-bit binaries on 64-bit platforms via 134 COMPAT_FREEBSD32 will remain supported for at least the 135 stable/15 and stable/16 branches. 136 137 Support for compiling individual 32-bit applications via 138 `cc -m32` will also be supported for at least the stable/15 139 branch which includes suitable headers in /usr/include and 140 libraries in /usr/lib32. 141 142 Support for 32-bit platforms in ports for 15.0 and later 143 releases is also deprecated, and these future releases may not 144 include binary packages for 32-bit platforms or support for 145 building 32-bit applications from ports. 146 147 stable/14 and earlier branches will retain existing 32-bit 148 kernel and world support. Ports will retain existing support 149 for building ports and packages for 32-bit systems on stable/14 150 and earlier branches as long as those branches are supported 151 by the ports system. However, all 32-bit platforms are Tier-2 152 or Tier-3 and support for individual ports should be expected 153 to degrade as upstreams deprecate 32-bit platforms. 154 155 With the current support schedule, stable/14 will be EOLed 5 156 years after the release of 14.0. The EOL of stable/14 would 157 mark the end of support for 32-bit platforms including source 158 releases, pre-built packages, and support for building 159 applications from ports. Given an estimated release date of 160 October 2023 for 14.0, support for 32-bit platforms would end 161 in October 2028. 162 163 The project may choose to alter this approach when 15.0 is 164 released by extending some level of 32-bit support for one or 165 more platforms in 15.0 or later. Users should use the 166 stable/14 branch to migrate off of 32-bit platforms. 167
