6f8a59eaeSWarner Losh19990830:
7f8a59eaeSWarner Losh	User-visible TCP timers are now expressed in units of 1ms, instead
8f8a59eaeSWarner Losh	of 500ms, so if you've customized any timer values under
9f8a59eaeSWarner Losh	``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior.

11f8a59eaeSWarner Losh19990821:
12f8a59eaeSWarner Losh	On 28-May-1999 libreadline was upgraded from readline-2.2 to
13f8a59eaeSWarner Losh	readline-4.0.  At that time the shared library major version
14f8a59eaeSWarner Losh	number was bumped from "3" to "4".  It has been deemed that
15f8a59eaeSWarner Losh	the interface change between readline-2.2 and readline-4.0 was
16f8a59eaeSWarner Losh	not suffient to warrant the version number bump.
17f8a59eaeSWarner Losh
18f8a59eaeSWarner Losh	Thus I have reverted it back to "3".  You will need to perform
19f8a59eaeSWarner Losh	the below immediately before your next ``make world'':
20f8a59eaeSWarner Losh	    cd /usr/lib
21f8a59eaeSWarner Losh	    ls -l libreadline.so.4
22f8a59eaeSWarner Losh	        (if you have /usr/lib/libreadline.so.4)
23f8a59eaeSWarner Losh	    mv libreadline.so.4 libreadline.so.3
24f8a59eaeSWarner Losh	    rm -f libreadline.so
25f8a59eaeSWarner Losh	    ln -s libreadline.so.3 libreadline.so
26f8a59eaeSWarner Losh
277eedd934SWarner Losh19990801:
287eedd934SWarner Losh	Changes to the pccardd kernel interface require that you recompile
297eedd934SWarner Losh	pccardd for new kernel.
307eedd934SWarner Losh
31882984b3SWarner Losh19980725:
32882984b3SWarner Losh	The ipfw interface to the kernel has changed.  You will need to
33882984b3SWarner Losh	recompile ipfw programs for the new kernel.
34882984b3SWarner Losh
35882984b3SWarner Losh19990715:
36882984b3SWarner Losh	The bpfilter device has been renamed to bpf.  You will need to
37882984b3SWarner Losh	change your config files in order to enable this in newer kernels.
38882984b3SWarner Losh
39e5bd655aSWarner Losh19990704:
40e5bd655aSWarner Losh	src/contrib/sys/softupdates is moving to
4195d18cfcSWarner Losh	src/sys/contrib/softupdates.  Update your symbolic links/etc.
42e5bd655aSWarner Losh
43e5bd655aSWarner Losh19990702:
44e5bd655aSWarner Losh	Major changes have been made to vinum and its interface.  See
45e5bd655aSWarner Losh	the man page (vinum(8)) for details.  Look at the concat,
46e5bd655aSWarner Losh	mirror and stripe commands, as well as the SIMPLIFIED
47e5bd655aSWarner Losh	CONFIGURATION section.
48e5bd655aSWarner Losh
49e5bd655aSWarner Losh19990628:
50e5bd655aSWarner Losh	Newsyslog.conf has had a minor, but potentially dangerous,
51e5bd655aSWarner Losh	change to its username/group syntax.  The old syntax was
52e5bd655aSWarner Losh	user.group, while the new syntax is user:group.
53e5bd655aSWarner Losh
54e5bd655aSWarner Losh19990627:
55e5bd655aSWarner Losh	Inetd wrapping default has changed.  Please see the updated
56e5bd655aSWarner Losh	man page for details.
57e5bd655aSWarner Losh
58ed478e7cSWarner Losh19990623:
59ed478e7cSWarner Losh	Compaq Smart Raid driver committed as ida.
60ed478e7cSWarner Losh
61075eeff2SWarner Losh19990622:
62075eeff2SWarner Losh	The second phase of syscons cleanup has happened.  Some
63075eeff2SWarner Losh	functionality has been made optional.  For details, see
64075eeff2SWarner Losh        http://www.freebsd.org/~yokota/sc_update-June.txt
656ae429caSWarner Losh	Everyone will need to re-config(8) their kernels, but old
666ae429caSWarner Losh	binaries will work with the new kernel.
67075eeff2SWarner Losh
68a883e9d3SWarner Losh19990620:
69a883e9d3SWarner Losh	IPFW uid/gid-based filtering support has been committed. This
70a883e9d3SWarner Losh	breaks binary compatibility with previous copies of
71a883e9d3SWarner Losh	ipfw(8). Any utilities using the ioctl()s of ipfw (especially
72a883e9d3SWarner Losh	ipfw(8)) need to be recompiled with the newest headers
73a883e9d3SWarner Losh	installed.
74a883e9d3SWarner Losh
75a883e9d3SWarner Losh19990618:
76a883e9d3SWarner Losh	Inetd now wraps all stream-based services, including internals.
77a883e9d3SWarner Losh	Syslog "severity" options are honoured. Installed syslog.conf
78a883e9d3SWarner Losh	and hosts.allow should be checked.
79a883e9d3SWarner Losh
8007b72539SWarner Losh19990509:
8107b72539SWarner Losh	Most of the problems with newbus have been corrected, but
8207b72539SWarner Losh	it is still current and evolving.
8307b72539SWarner Losh
8407b72539SWarner Losh	libcam's ABI has changed.  You must recompile the world and
8507b72539SWarner Losh	any ports that use it.
8607b72539SWarner Losh
8709fcf3f9SWarner Losh19990427:
8809fcf3f9SWarner Losh	Massive changes to SMP went into the tree that should speed
8909fcf3f9SWarner Losh	things up.  However, if you experience problems with SMP
9009fcf3f9SWarner Losh	machines, you can back off to the PRE_SMP_VMSHARE tag in the
9109fcf3f9SWarner Losh	CVS repository (or run an MP kernel).
9209fcf3f9SWarner Losh
9309fcf3f9SWarner Losh19990420:
9409fcf3f9SWarner Losh	Pccardd and the pccard bus in general seem to be broken or
9509fcf3f9SWarner Losh	most people.  Soren has patches to make it better for some,
9609fcf3f9SWarner Losh	but not all people.  Work is underway to make it better for
9709fcf3f9SWarner Losh	all people.
9809fcf3f9SWarner Losh
99ea31d04dSWarner Losh19990416:
100ea31d04dSWarner Losh	new bus changes integrated into -current.  Many problems were
101ea31d04dSWarner Losh	initially reported, but most have been fixed.  You'll need a
102ea31d04dSWarner Losh	new config and to tweak your kernel config file the way that
103ea31d04dSWarner Losh	GENERIC was tweaked.  Keep a copy of your old kernel when
104ea31d04dSWarner Losh	upgrading in case your new kernel doesn't work (and report the
105ea31d04dSWarner Losh	breakage to current@freebsd.org).
106ea31d04dSWarner Losh
107ea31d04dSWarner Losh	As of 19990421 the remaining problems/quirks are
108ea31d04dSWarner Losh
109ea31d04dSWarner Losh	o sio no longer supports pnp nor pccard.  This will be corrected,
110ea31d04dSWarner Losh	  but the new pccard code needs to be completed.
111ea31d04dSWarner Losh	o Some of the sound drivers broke for some people.  It seems
112ea31d04dSWarner Losh	  inconsistant as to who/what/when/where things broke.
113ea31d04dSWarner Losh	o Duplicate device entries in your config do not work.  Previously
114ea31d04dSWarner Losh	  they were silently ignored.  psm0 seems to be the most common
115ea31d04dSWarner Losh	  duplicate choice, although some reports have come in from people
116ea31d04dSWarner Losh	  that wired their scsi disk entries.
117ea31d04dSWarner Losh	o You must move the keyboard and mouse attachments from the
118ea31d04dSWarner Losh	  isa bus to the atkbdc bus.  See GENERIC for details.
119ea31d04dSWarner Losh	o Machines with multiple host-pci bridges (Intel 450NX) will not
120ea31d04dSWarner Losh	  probe the second pci bus.
121ea31d04dSWarner Losh	o Some probe ordering may have changed, so device naming may change
122ea31d04dSWarner Losh	  with the new kernel.  If you have multiple devices, please double
123ea31d04dSWarner Losh	  check to make sure they didn't move.  This is especially true
124ea31d04dSWarner Losh	  for cards on different buses.
125ea31d04dSWarner Losh	o The bus attachment for vga0 is always isa0 and never pci0 when
126ea31d04dSWarner Losh	  it is in fact a pci card.  It is safe to ignore this.
127ea31d04dSWarner Losh	o The format of the boot messages has changed (and is not
128ea31d04dSWarner Losh	  guaranteed to be constant for a while) so you may see this
129ea31d04dSWarner Losh	  in some shell scripts that diff dmesg from day to day as well
130ea31d04dSWarner Losh	  as scripts that parse dmesg output.
131f8c77507SWarner Losh
132d24adca8SWarner Losh19990414:
133d24adca8SWarner Losh	cc -aout sometimes has problems compiling with -g, remove -g
134d24adca8SWarner Losh	from those compilation units affected until this is corrected.
135d24adca8SWarner Losh
136d24adca8SWarner Losh	cc -aout has problems with producing some threaded libraries,
137d24adca8SWarner Losh	so make world -DWANT_AOUT is not functional at this time.
138d24adca8SWarner Losh
139ea31d04dSWarner Losh	Since make world for a.out isn't functional, you cannot do
140ea31d04dSWarner Losh	make aout-to-elf from a pre-egcs a.out system.  To work around
141ea31d04dSWarner Losh	this problem, make aout-to-elf using 3.1-stable first (or a
142ea31d04dSWarner Losh	pre egcs -current) and then a simple make world will take you
143ea31d04dSWarner Losh	the rest of the way with a -current source base.
144ea31d04dSWarner Losh
145d5ca0636SWarner Losh19990413:
146d24adca8SWarner Losh	Make -j works again for make world.  As always, use it with
147d24adca8SWarner Losh	care, and be sure to try a make world w/o -j before reporting
148d24adca8SWarner Losh	problems (that is, know if the problem exists w/o -j before
149d24adca8SWarner Losh	reporting the problem with -j).
150d24adca8SWarner Losh
151d24adca8SWarner Losh19990413:
152d24adca8SWarner Losh	Note cc -aout, which had been broken since the conversion to
153ea31d04dSWarner Losh	egcs, now supposedly works.  If you have rebuilt things like
154d24adca8SWarner Losh	XFree86 a.out libraries, you should rebuild them again or
155ea31d04dSWarner Losh	progams that use them, including netscape, will fail to work.
156d5ca0636SWarner Losh
1571f692d40SWarner Losh19990409:
1581f692d40SWarner Losh	NOTE: New c++ compiler cannot be used with c++ binaries from
1591f692d40SWarner Losh	the old compiler and vice versa.
1601f692d40SWarner Losh
1611f692d40SWarner Losh19990408:
16281725689SWarner Losh	In recent days egcs has been imported into the tree.  A number
16381725689SWarner Losh	of problems have been discussed in -current.  Here is a highlight
16481725689SWarner Losh	of a few of the more common ones.  With the exception of make
16581725689SWarner Losh	-j n, they have been claimed to have been fixed.
16681725689SWarner Losh
16781725689SWarner Losh	c++ is broken after make world: This is correct.  Because we
16881725689SWarner Losh	changed compilers two make worlds are necessary to get C++
16981725689SWarner Losh	working again.  The code generated by the old compiler and new
17081725689SWarner Losh	compiler are not compatible, so things wind up being
17181725689SWarner Losh	undefined.
17281725689SWarner Losh
17381725689SWarner Losh	cpp is broken in make world:  There was a window where cpp
17481725689SWarner Losh	would be built incorrectly.  The fix for this is
175420d4744SMasafumi Max NAKANE		cd src/gnu/usr.bin/cc
17681725689SWarner Losh		make clean
17781725689SWarner Losh		make all
17881725689SWarner Losh		make install
17981725689SWarner Losh	and this should correct your problems.  See the -current
18081725689SWarner Losh	archives for a version of this that does moer cleaning.
18181725689SWarner Losh
18281725689SWarner Losh	Make -j n doesn't work.  Work contiunes to make this work,
18381725689SWarner Losh	I've seen no reports of success as of April 7th.
18481725689SWarner Losh
185ff5e1f79SWarner Losh19990329:
186ff5e1f79SWarner Losh	Previously, one would define "NOAOUT" to keep from building
187ff5e1f79SWarner Losh	the legacy a.out bits.  Now one would define "WANT_AOUT" to
188ff5e1f79SWarner Losh	build them.
189ff5e1f79SWarner Losh
190fe9af953SWarner Losh19990316:
191fe9af953SWarner Losh	The name of the old wd.c and atapi.c based CDROM driver has
192fe9af953SWarner Losh	been changed back to wcd. So update your config file to use
193fe9af953SWarner Losh	"device wcd" instead of "device acd".
194fe9af953SWarner Losh
195fe9af953SWarner Losh19990314:
196fe9af953SWarner Losh	For those of you using the VN device as a loadable module,
197fe9af953SWarner Losh	please be aware that the new VN device has been committed to
198fe9af953SWarner Losh	-4.x and cannot yet be used as a loadable module.  This will
199fe9af953SWarner Losh	be fixed in the future.
200fe9af953SWarner Losh
201ce32355fSWarner Losh19990309:
202fe9af953SWarner Losh	New loader.rc mechanism.  Please see src/sys/boot/README for
203fe9af953SWarner Losh	details.
204ce32355fSWarner Losh
205f8c77507SWarner Losh19990225:
206f8c77507SWarner Losh	struct proc size changed.  Recompile kernel and the
207f8c77507SWarner Losh	usual suspects.  Make world if in doubt.
2081fc1a0dcSWarner Losh
2090edeb9e7SWarner Losh19990214:
2100edeb9e7SWarner Losh	The nlpt driver has changed names back to be the lpt driver.
2117dd38e55SWarner Losh	See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
2127dd38e55SWarner Losh	for proper configuration details.
2130edeb9e7SWarner Losh
2141fc1a0dcSWarner Losh19990210:
2151fc1a0dcSWarner Losh	The 'lpt' driver is now obsolete.  Replace it with the 'nlpt'
2160edeb9e7SWarner Losh	driver and 'ppbus' controller combination.
21757199806SWarner Losh
2187dd38e55SWarner Losh19990209:
2197dd38e55SWarner Losh	New devstat API requires recompilation of libdevstat, systat,
2207dd38e55SWarner Losh	iostat, vmstat and rpc.rstatd.  A new kernel is also required.
2217dd38e55SWarner Losh	make world + building a kernel should do all of this.  Any
2227dd38e55SWarner Losh	ports that use devstat need to be recompiled as well.
2237dd38e55SWarner Losh
2249a3105eeSWarner Losh19990125:
2259a3105eeSWarner Losh	Linux threads options has gone away (they are now standard in
2269a3105eeSWarner Losh	the FreeBSD kernel).  A recompile of all libkvm using programs
2279a3105eeSWarner Losh	is in order (or better yet a make world).
2289a3105eeSWarner Losh
2299a3105eeSWarner Losh19990122:
2309a3105eeSWarner Losh	On or about this date there was a small window when the boot
2319a3105eeSWarner Losh	blocks had some minor problems which seemed to force one to
2329a3105eeSWarner Losh	edit /etc/fstab.  This has been corrected, if you are seeing this
2339a3105eeSWarner Losh	problem, please rebuild and reinstall your boot blocks.
2349a3105eeSWarner Losh
2359a3105eeSWarner Losh19990121:
2368cd37f69SWarner Losh	Vinum has changed.  The "vinum read" command has changed.  For
2378cd37f69SWarner Losh	updates, please see
2383652181cSWarner Losh
2398cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
2403652181cSWarner Losh
2418cd37f69SWarner Losh	for details.
2428cd37f69SWarner Losh
2438cd37f69SWarner Losh	Matt Dillon committed a boatload of VM changes, for
2448cd37f69SWarner Losh	information please see
2453652181cSWarner Losh
2468cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current

2493652181cSWarner Losh
2508cd37f69SWarner Losh	for details.  These changes will likely not impact anybody,
2518cd37f69SWarner Losh	but large chagnes to the VM need at least a heads up.
2528cd37f69SWarner Losh
2538cd37f69SWarner Losh19990120:
2548cd37f69SWarner Losh	Stable branch created.  You might want to consider using this
2558cd37f69SWarner Losh	branch.  It is tagged with RELENG_3.
2568cd37f69SWarner Losh
257ad56ea87SWarner Losh19990119:
258ad56ea87SWarner Losh	More work on the syscons driver has been committed.  Since
259ad56ea87SWarner Losh	files moved around, you will need to reconfigure your kernel,
260ad56ea87SWarner Losh	and make clean; make depend before rebuilding the kernel.  No
261ad56ea87SWarner Losh	config file changes are needed.
262ad56ea87SWarner Losh
26357199806SWarner Losh19990111:
264a85c0f55SWarner Losh	New keyboard and video card drivers are introduced as the first
265a85c0f55SWarner Losh	stage of console driver reorganization.  You are required to
266a85c0f55SWarner Losh	update the kernel configuration file and rebuild the kernel.
267a85c0f55SWarner Losh	kbdcontrol, vidcontrol, and screen savers also need recompilation.
268a85c0f55SWarner Losh	The instruction can be found in
26957199806SWarner Losh
2707dafbc29SWarner Losh		http://www.freebsd.org/~yokota/sc_update.txt
27157199806SWarner Losh
272a85c0f55SWarner Losh	It has notes on splash screen too.
27357199806SWarner Losh
27457199806SWarner Losh19990106:
2759857e582SWarner Losh	Robert Nordier was kind enough to make this page to enable people to
276db23c94fSWarner Losh	install the new bootblocks:
27757199806SWarner Losh
2787dafbc29SWarner Losh		http://www.freebsd.org/~rnordier/boot.txt
27957199806SWarner Losh
2809ba54ae0SWarner Losh	When updating to ELF, make sure that you have updated your
2819ba54ae0SWarner Losh	/etc/rc files which have different ldconfig invocations for
2829ba54ae0SWarner Losh	elf and aout.  Otherwise things like X will stop working with
2839857e582SWarner Losh	messages about being unable to find library files.  The
2849857e582SWarner Losh	mergemaster utility in ports/sysutils/mergemaster helps to
2859857e582SWarner Losh	keep critical files like this in sync, and its use is
2869857e582SWarner Losh	recommended.

297d5513f53SWarner Losh	You should install new bootblocks now.  The ELF kernel will
298e363c17bSWarner Losh	become default soon.  In addition, you'll need to upgrade
299e363c17bSWarner Losh	your userland programs to ELF before then as well.  Use
300e363c17bSWarner Losh	make aout-to-elf to upgrade your userland programs (old
301e363c17bSWarner Losh	a.out programs in, for example, /usr/local/bin will
302e363c17bSWarner Losh	continue to work, even after the upgrade).  See src/Makefile
303e363c17bSWarner Losh	for more details.

317ab308df6SWarner Losh	New groups from 19981201 commented out of mtree, so they
