Recent changes: ^^^^^^^^^^^^^^^ +20090529: + pkg_install now depends on the pkgdb cache for automatic conflict + detection. It is recommented to rebuild the cache with + ``pkg_admin rebuild''. + + audit-packages.conf(5) has been superseded by pkg_install.conf(5). + The default configuration is the same. Support for pkg_view(1) has + been retired. The functionality of audit-packages(1) and + download-vulnerability-list(1) has moved into pkg_admin(1), wrapper + scripts that handle the common use cases are provided. + +20061108: + The configure script used in the src/tools/gcc compiler has been + changed to indicate that our libc has ssp support built-in and + does not depend on -lssp and -lssp-nonshared. You'll need to + make clean in src/tools/gcc first to rebuild the compiler. + +20061009: + The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer + available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. + +20060814: + The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been + withdrawn. Use vidcvideo and pckbd instead. See the GENERIC + kernel configuration for an example. X servers from the last + few years should cope. + +20060703: + MPACPI is no more. We always configure PCI interrupts using ACPI + if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed + to ACPI_SCANPCI. Thanks to work from fvdl. + +20060627: + socket(2) has changed, and its system call has been versioned. + For userlands with the old version of socket(2), make sure that + your kernel has 'options COMPAT_30' set, or else 'bad system call' + errors will result. + +20060526: + The kernel linker scripts for i386 and xen + (sys/arch/i386/conf/kern.ldscript*) were changed to set the + load address correctly, for the benefit of MULTIBOOT boot loaders + (like Grub). If you use a linker (ld) older than from 2006/04/17, it + will be unable to link the kernel because of a bug and ld will fail + with an error like: + ../../../../arch/i386/conf/kern.ldscript:45 \ + non constant expression for load base + You need to update at least src/gnu/dist/binutils/ld and recompile + and install the linker. If using the build.sh script, the easiest + way is with a "build.sh tools" command, with any other options + that you use normally. When using build.sh, the linker binary is + installed as ${TOOLDIR}/bin/i386--netbsdelf-ld. + +20060131: + the protocol between the sparc64 bootloader (ofwboot) and + the kernel was changed. Before installing a new kernel, + you need to update ofwboot. After a full build, just copy + /usr/mdec/ofwboot to /, or do a rebuild of + src/sys/arch/sparc/stand/ofwboot and install the result to /. + +20050917: + arch/*/conf/std.* was changed to include conf/std, which + contains MI options previously enabled by default. + If you have kernel config files which doesn't include + arch/*/conf/std.*, you need to edit them to include conf/std + to get the previous configuration. + +20050830: + named.conf was moved from /etc/namedb to /etc. + postinstall(8) migrates this during interactive use. + Users of MKUPDATE=yes will need to manually rectify + this in their DESTDIR. + +20050825: + Some data structures in sys/device.h, related to interface + attributes and locator names, were changed. config(1) was + modified to emit the new data structures. + Thus usr.bin/config must be updated (and run on the kernel + configuration file) before a new kernel can be built. + +20050531: + genassym.sh(8) was moved to genassym(1). You need to either build + tools first or install the version of genassym from /usr/bin before + you can build a kernel again. + +20050520: + Because a kernfs bug which xentools relies on was fixed, + xentools up to xentools20-2.0.3nb4 won't work with new kernel. + +20050417: + postinstall(8) was moved from /etc to /usr/sbin and made part + of the "base" set, to make it easier to invoke after an + upgrade. + +20050325: + pcppi(4) was separated in two devices, adding attimer(4). Be sure + to add a config line for an attimer(4) device in your kernel + configuration, or you won't be able to set the pitch of the beep + with wsconsctl. Depending on the default value for the pitch, you + might even not hear any more beep. Also, it is advised to attach both + devices the same way (i.e., both on isa or both on acpi) or the + pcppi(4) device may fail to find the attimer(4) one. + +20050211: + Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in + some of the cross tools to fail if they use configure. Some configure's + cache the environment passed in and notice the new environment is + different and abort. Doing a clean in tools/ should be enough to + make a build continue. + +20050109: + Since su is using pam by default now, make sure that you have + /etc/pam.d populated (postinstall will do that automatically + for you). Otherwise su will fail open (i.e. will not require + a password). + +20041229: + Make had a path resolution bug that manifested itself as not + being able to install openpam.3. This bug has been fixed, but + you might need to rebuild make manually first to get through + the build. + +20041201: + Userland programs have been changed to use /dev/bpf instead of + /dev/bpfX. You need to create that device by installing a new + MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]* + +20041006: + + A bug was introduced into /bin/sh (var.c rev 1.35) which causes + variables to not export correctly to subshells in all cases. This + will cause builds to break if that version of /bin/sh is installed + on the system. The proper version of /bin/sh can be verified with: + + ident /bin/sh | grep var + + Any /bin/sh w. version 1.35 will not work and needs to be updated + before attempting a build. + +20041001: + The ipfilter kernel sources moved from sys/netinet to + dist/sys/ipf/netinet. Due to the move some Makefile + dependencies are now dangling requiring a make cleandir + before they work again (kdump, ktruss, rescue, ipf, and + ftp-proxy are the victims). + +20040715: + The rc.d/sendmail script now uses a heuristic to determine + if sendmail should be started at boot time. It checks the + contents of /etc/mailer.conf, /etc/mail/submit.cf, and the + owner and mode of the sendmail binary to see if any changes + to the mail infrastructure have been made. If no changes + are detected, it will start an SMTP listener. + + Setting sendmail=NO in /etc/rc.conf will override this. + + If you are only using sendmail by default and only for + local delivery, it is important that you also update your + sendmail.cf so that the SMTP listener only listens on the + loopback interface. + +20040715: + The method by which athhal-elf.o gets pulled into i386 + kernel builds has been changed again.
