1Release notes for FreeBSD 14.0. 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 13616f32ea6da7: 14 mta_start_script along with othermta rc.d script has been retired. 15 16a67b925ff3e5: 17 The default mail transport agent is now dma(8) replacing sendmail. 18 1922893e584032: 20 L3 filtering on if_bridge will do surprising things which aren't 21 fail-safe, so net.link.bridge.pfil_member and 22 net.link.bridge.pfil_bridge now default to zero. 23 24f0bc4ed144fc: 25 A new DTrace provider, kinst, is introduced and documented in 26 dtrace_kinst(4). The provider allows kernel instructions to be traced, 27 similar to the FBT (function boundary tracing) provider except that all 28 instructions may be probed instead of logical entry and return 29 instructions. The provider is currently amd64-only. 30 310eea46fb1f83: 32 Removed telnetd. 33 34981ef32230b2,33721eb991d8: 35 These commits make the use of NFSv4.1/4.2 mounts with the "intr" 36 mount option fairly usable, although not 100% correct, so long as 37 the "nolockd" mount option is used as well. See the mount_nfs(8) 38 manual page for more information. 39 40b875d4f5ddcb,0685c73cfe88: 41 The NFSv4.1/4.2 client and server will now generate console messages 42 if sessions are broken, suggesting that users check to ensure 43 that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients. 44 45240afd8c1fcc: 46 makefs(8) has ZFS support; it can create a ZFS pool, backed by a 47 single disk vdev, containing one or more datasets populated from 48 the staging directory. 49 5078ee8d1c4cda,f4f56ff43dbd: 51 The in-tree qat(4) driver has been replaced with Intel's QAT driver. 52 The new version provides additional interfaces to the chipset's 53 cryptographic and compression offload functionality. 54 55 This will have no visible change for most users; however, the new 56 driver does not support Atom C2000 chipsets. To preserve support for 57 those chipsets, the old driver has been renamed to qat_c2xxx and kept 58 in the tree. Users of qat(4) on C2000 hardware will thus need to 59 ensure that qat_c2xxx(4) is loaded instead of qat(4). 60 61da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21: 62 Boottrace is a new kernel-userspace interface for capturing trace 63 events during system boot and shutdown. Event annotations are 64 present in: 65 66 - The boot and shutdown paths in the kernel 67 - Some key system utilities (init(8), shutdown(8), reboot(8)) 68 - rc(8) scripts (via boottrace(8)) 69 70 In contrast to other existing boot-time tracing facilities like TSLOG, 71 Boottrace focuses on the ease of use and is aimed primarily at system 72 administrators. 73 74 It is available in the default GENERIC kernel and can be enabled by 75 toggling a single sysctl(8) variable. 76 77 See boottrace(4) for more details. 78 7905a1d0f5d7ac: 80 Kernel TLS offload now supports receive-side offload of TLS 1.3. 81 8219dc64451179: 83 if_stf now supports 6rd (RFC5969). 84 85c1d255d3ffdb, 3968b47cd974, bd452dcbede6: 86 Add WiFi 6 support to wpa. 87 88ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9: 89 The default bell tone is now 800Hz. It may be set with kbdcontrol 90 again. There's devd integration for people wishing to use their sound 91 cards for the beep. 92 9392b3e07229ba: 94 net.inet.tcp.nolocaltimewait enabled by default. It prevents 95 creation of timewait entries for TCP connections that were 96 terminated locally. 97 98d410b585b6f0: 99 sh(1) is now the default shell for the root user. 100 101396851c20aeb: 102 libncursesw has been split into libtinfow and libncursesw, linker 103 scripts should make it transparent for consumers. pkg-config files 104 are also now installed to ease ports detecting the ncurses setup from 105 base. 106 107a422084abbda: 108 LLVM's MemorySanitizer can now be used in amd64 kernels. See the 109 kmsan(9) manual page for more information. 110 11138da497a4dfc: 112 LLVM's AddressSanitizer can now be used in amd64 kernels. See the 113 kasan(9) manual page for more information. 114 115f39dd6a97844,23f24377b1a9,628bd30ab5a4: 116 One True Awk has been updated to the latest from upstream 117 (20210727). All the FreeBSD patches, but one, have now been 118 either up streamed or discarded. Notable changes include: 119 o Locale is no longer used for ranges 120 o Various bugs fixed 121 o Better compatibility with gawk and mawk 122 123 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 124 we still allow hex numbers, prefixed with 0x, to be parsed and 125 interpreted as hex numbers while all other awks (including one 126 true awk now) interpret them as 0 in line with awk's historic 127 behavior. 128 129 A second change, less likely to be noticed, is the historic wart 130 if -Ft meaning to use hard tab characters as the field separator 131 is deprecated and will likely be removed in FreeBSD 14. 132 133ee29e6f31111: 134 Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio 135 that can be used to increase the maximum I/O size for the NFS 136 server to any power of 2 up to 1Mbyte while the nfsd(8) is not running. 137 The FreeBSD NFS client can now be set to use a 1Mbyte I/O size 138 via the vfs.maxbcachebuf tunable and the Linux NFS client 139 can also do 1Mbyte I/O. 140 kern.ipc.maxsockbuf will need to be increased. A console 141 message will suggest a setting for it. 142 143d575e81fbcfa: 144 gconcat(8) has added support for appending devices to the device 145 not present at creation time. 146 14776681661be28: 148 Remove support for asymmetric cryptographic operations from 149 the kernel open cryptographic framework (OCF). 150 151a145cf3f73c7: 152 The NFSv4 client now uses the highest minor version of NFSv4 153 supported by the NFSv4 server by default instead of minor version 0, 154 for NFSv4 mounts. 155 The "minorversion" mount option may be used to override this default. 156
