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 132fb4f839f3fc,d89513ed2050,3413ee88c39d,f97a19ecb985,021562c5020d,431d2a81d421: 14 sendmail has been updated to the latest upstream version (8.17.1). 15 164a30d7bb373c,d670a8f7c596,af01b4722577,4e240e55d818: 17 The growfs(7) script can now add a swap partition at the end of 18 the expansion area, and does so by default if there is no existing 19 swap. See growfs(7). 20 2186edb11e7491: 22 llvm-objump is now always installed as objdump. 23 24616f32ea6da7: 25 mta_start_script along with othermta rc.d script has been retired. 26 27a67b925ff3e5: 28 The default mail transport agent is now dma(8) replacing sendmail. 29 3022893e584032: 31 L3 filtering on if_bridge will do surprising things which aren't 32 fail-safe, so net.link.bridge.pfil_member and 33 net.link.bridge.pfil_bridge now default to zero. 34 35f0bc4ed144fc: 36 A new DTrace provider, kinst, is introduced and documented in 37 dtrace_kinst(4). The provider allows kernel instructions to be traced, 38 similar to the FBT (function boundary tracing) provider except that all 39 instructions may be probed instead of logical entry and return 40 instructions. The provider is currently amd64-only. 41 420eea46fb1f83: 43 Removed telnetd. 44 45981ef32230b2,33721eb991d8: 46 These commits make the use of NFSv4.1/4.2 mounts with the "intr" 47 mount option fairly usable, although not 100% correct, so long as 48 the "nolockd" mount option is used as well. See the mount_nfs(8) 49 manual page for more information. 50 51b875d4f5ddcb,0685c73cfe88: 52 The NFSv4.1/4.2 client and server will now generate console messages 53 if sessions are broken, suggesting that users check to ensure 54 that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients. 55 56240afd8c1fcc: 57 makefs(8) has ZFS support; it can create a ZFS pool, backed by a 58 single disk vdev, containing one or more datasets populated from 59 the staging directory. 60 6178ee8d1c4cda,f4f56ff43dbd: 62 The in-tree qat(4) driver has been replaced with Intel's QAT driver. 63 The new version provides additional interfaces to the chipset's 64 cryptographic and compression offload functionality. 65 66 This will have no visible change for most users; however, the new 67 driver does not support Atom C2000 chipsets. To preserve support for 68 those chipsets, the old driver has been renamed to qat_c2xxx and kept 69 in the tree. Users of qat(4) on C2000 hardware will thus need to 70 ensure that qat_c2xxx(4) is loaded instead of qat(4). 71 72da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21: 73 Boottrace is a new kernel-userspace interface for capturing trace 74 events during system boot and shutdown. Event annotations are 75 present in: 76 77 - The boot and shutdown paths in the kernel 78 - Some key system utilities (init(8), shutdown(8), reboot(8)) 79 - rc(8) scripts (via boottrace(8)) 80 81 In contrast to other existing boot-time tracing facilities like TSLOG, 82 Boottrace focuses on the ease of use and is aimed primarily at system 83 administrators. 84 85 It is available in the default GENERIC kernel and can be enabled by 86 toggling a single sysctl(8) variable. 87 88 See boottrace(4) for more details. 89 9005a1d0f5d7ac: 91 Kernel TLS offload now supports receive-side offload of TLS 1.3. 92 9319dc64451179: 94 if_stf now supports 6rd (RFC5969). 95 96c1d255d3ffdb, 3968b47cd974, bd452dcbede6: 97 Add WiFi 6 support to wpa. 98 99ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9: 100 The default bell tone is now 800Hz. It may be set with kbdcontrol 101 again. There's devd integration for people wishing to use their sound 102 cards for the beep. 103 10492b3e07229ba: 105 net.inet.tcp.nolocaltimewait enabled by default. It prevents 106 creation of timewait entries for TCP connections that were 107 terminated locally. 108 109d410b585b6f0: 110 sh(1) is now the default shell for the root user. 111 112396851c20aeb: 113 libncursesw has been split into libtinfow and libncursesw, linker 114 scripts should make it transparent for consumers. pkg-config files 115 are also now installed to ease ports detecting the ncurses setup from 116 base. 117 118a422084abbda: 119 LLVM's MemorySanitizer can now be used in amd64 kernels. See the 120 kmsan(9) manual page for more information. 121 12238da497a4dfc: 123 LLVM's AddressSanitizer can now be used in amd64 kernels. See the 124 kasan(9) manual page for more information. 125 126f39dd6a97844,23f24377b1a9,628bd30ab5a4: 127 One True Awk has been updated to the latest from upstream 128 (20210727). All the FreeBSD patches, but one, have now been 129 either up streamed or discarded. Notable changes include: 130 o Locale is no longer used for ranges 131 o Various bugs fixed 132 o Better compatibility with gawk and mawk 133 134 The one FreeBSD change, likely to be removed in FreeBSD 14, is that 135 we still allow hex numbers, prefixed with 0x, to be parsed and 136 interpreted as hex numbers while all other awks (including one 137 true awk now) interpret them as 0 in line with awk's historic 138 behavior. 139 140 A second change, less likely to be noticed, is the historic wart 141 if -Ft meaning to use hard tab characters as the field separator 142 is deprecated and will likely be removed in FreeBSD 14. 143 144ee29e6f31111: 145 Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio 146 that can be used to increase the maximum I/O size for the NFS 147 server to any power of 2 up to 1Mbyte while the nfsd(8) is not running. 148 The FreeBSD NFS client can now be set to use a 1Mbyte I/O size 149 via the vfs.maxbcachebuf tunable and the Linux NFS client 150 can also do 1Mbyte I/O. 151 kern.ipc.maxsockbuf will need to be increased. A console 152 message will suggest a setting for it. 153 154d575e81fbcfa: 155 gconcat(8) has added support for appending devices to the device 156 not present at creation time. 157 15876681661be28: 159 Remove support for asymmetric cryptographic operations from 160 the kernel open cryptographic framework (OCF). 161 162a145cf3f73c7: 163 The NFSv4 client now uses the highest minor version of NFSv4 164 supported by the NFSv4 server by default instead of minor version 0, 165 for NFSv4 mounts. 166 The "minorversion" mount option may be used to override this default. 167
