                                 RELEASE NOTES
                          FreeBSD Release 3.0-SNAPSHOT

This is a SNAPSHOT release of FreeBSD 3.0-CURRENT and is aimed primarily
at release testers.  Some parts of the documentation may not be updated
yet and should be reported if and when seen.  Naturally, any installation
failures or crashes should also be reported ASAP by sending mail to
freebsd-bugs@FreeBSD.org or using the send-pr command (those preferring a 
WEB based interface can also see http://www.freebsd.org/send-pr.html).

For information about FreeBSD and the layout of the 3.0-SNAPSHOT release
directory (especially if you're installing from floppies!), see ABOUT.TXT.
For installation instructions, see the INSTALL.TXT and HARDWARE.TXT files.


1. What's new since 2.2.X-RELEASE
------------------------------------

KERNEL CHANGES:

The code from 4.4BSD-Lite2 has been (finally) merged.

The SMP (Symmetric MultiProcessing) branch has been merged.

Secure RPC is now supported (and usable with NFS et al).

Sun's WEBNFS standard is now supported.

Use the new if_multiaddrs list for multicast addresses rather than the
previous hackery involving struct in_ifaddr and arpcom.  Get rid of the
abominable multi_kludge.

The new if_media selection method for ethernet drivers has been brought
in, obtained from Jason Thorpe's implementation for NetBSD.

Multi-session ISO-9660 CD-ROMs are now fully supported.  By default, the
last session will be mounted (including for root mounts).  For non-root
mounts, mount_cd9660(8) can take an argument to mount a particular
session instead of the default one.

The UPAGES are gone from the per-process address space which allows
complete address space and page table sharing by reference count.

Newly forked child processes return directly to user mode rather than
return up through the fork() syscall tree.  This eliminates the kernel
stack copy at fork time and simplifies certain other internal operations. 
It is also needed to support the removal of the UPAGES.  (The idea for
this originally came from NetBSD, but we did it for different reasons.)

vfork() is now fully functional by taking advantage of the new sharing
semantics and a significant speedup has been measured.  This can be
disabled via the kern.fast_vfork sysctl variable in case of problems.
Statically linked binaries from older releases and other BSD platforms
are a problem since there was a bug in the 4.4BSD (net2, Lite and Lite2)
popen() implementation.

With the contribution of Berkeley Software Design, Inc., Jonathan Lemmon,
Mike Smith, Sean Eric Fagan, and John Dyson, VM86 support has been added
to the kernel, and BSD/OS's contributed dosemu has been ported.


SECURITY CHANGES:

7/29	Lots of lpr/lpd security fixes merged from OpenBSD.
8/22	buffer overflows in tip corrected (benign since tip isn't
	set[ug]id)
8/26	buffer overflow in glob fixed, no know exploits
8/27	vacation security problem with sendmail corrected (SNI)
8/29	inetd sleeps less when children exit, making DoS attacks much
	harder.
8/29	fts now race-proof and find -execdir added (-current only)

The suidperl vulnerability mentioned in the CERT advisory CA-97.17 is
also believed to be fixed.


USERLAND CHANGES:

The default username length has increased to 16 characters.
Caution:  Old utmp/wtmp files will NOT work with this change since
the data records will be of the old size.  For a conversion utility
to aid with this, see /usr/src/tools/3.0-upgrade.

/etc/sysconfig now replaced by more compact /etc/rc.conf file
(new since 2.2.1).

fdisk(8) now numbers disk slices from 1 to 4 rather than from 0 to 3.
This brings it in line with the numbers used in the device names
in /dev.


2. Supported Configurations
---------------------------

FreeBSD currently runs on a wide variety of ISA, VLB, EISA and PCI bus
based PC's, ranging from 386sx to Pentium class machines (though the
386sx is not recommended).  Support for generic IDE or ESDI drive
configurations, various SCSI controller, network and serial cards is
also provided.

What follows is a list of all peripherals currently known to work with
FreeBSD.  Other configurations may also work, we have simply not as yet
received confirmation of this.


2.1. Disk Controllers
---------------------

WD1003 (any generic MFM/RLL)
WD1007 (any generic IDE/ESDI)
IDE
ATA

Adaptec 1535 ISA SCSI controllers
Adaptec 154x series ISA SCSI controllers
Adaptec 174x series EISA SCSI controller in standard and enhanced mode.
Adaptec 274X/284X/2940/3940 (Narrow/Wide/Twin) series ISA/EISA/PCI SCSI
controllers.
Adaptec AIC7850 on-board SCSI controllers.

Adaptec AIC-6260 and AIC-6360 based boards, which includes the AHA-152x
and SoundBlaster SCSI cards.

** Note: You cannot boot from the SoundBlaster cards as they have no
   on-board BIOS, such being necessary for mapping the boot device into the
   system BIOS I/O vectors.  They're perfectly usable for external tapes,
   CDROMs, etc, however.  The same goes for any other AIC-6x60 based card
   without a boot ROM.  Some systems DO have a boot ROM, which is generally
   indicated by some sort of message when the system is first powered up
   or reset, and in such cases you *will* also be able to boot from them.
   Check your system/board documentation for more details.

3. Obtaining FreeBSD
--------------------

You may obtain FreeBSD in a variety of ways:

3.1. FTP/Mail
-------------

You can ftp FreeBSD and any or all of its optional packages from
`ftp.freebsd.org' - the official FreeBSD release site.

For other locations that mirror the FreeBSD software see the file
MIRROR.SITES.  Please ftp the distribution from the site closest (in
networking terms) to you.  Additional mirror sites are always welcome!
Contact freebsd-admin@FreeBSD.org for more details if you'd like to 
become an official mirror site.

If you do not have access to the Internet and electronic mail is your
only recourse, then you may still fetch the files by sending mail to
`ftpmail@ftpmail.vix.com' - putting the keyword "help" in your message
to get more information on how to fetch files using this mechanism.
Please do note, however, that this will end up sending many *tens of
megabytes* through the mail and should only be employed as an absolute
LAST resort!


3.2. CDROM
----------

FreeBSD 3.0-SNAP and 2.2.x-RELEASE CDs may be ordered on CDROM from:

        Walnut Creek CDROM
        4041 Pike Lane, Suite D
        Concord CA  94520
        1-800-786-9907, +1-510-674-0783, +1-510-674-0821 (FAX)

Or via the Internet from orders@cdrom.com or http://www.cdrom.com.
Their current catalog can be obtained via ftp from:

        ftp://ftp.cdrom.com/cdrom/catalog

Cost per -RELEASE CD is $39.95 or $24.95 with a FreeBSD subscription.
FreeBSD 3.0-SNAP CDs are $39.95 or $14.95 with a FreeBSD-SNAP subscription
(-RELEASE and -SNAP subscriptions are entirely separate).  With a
subscription, you will automatically receive updates as they are released.
Your credit card will be billed when each disk is shipped and you may cancel
your subscription at any time without further obligation.

Shipping (per order not per disc) is $5 in the US, Canada or Mexico
and $9.00 overseas.  They accept Visa, Mastercard, Discover, American
Express or checks in U.S. Dollars and ship COD within the United
States.  California residents please add 8.25% sales tax.

Should you be dissatisfied for any reason, the CD comes with an
unconditional return policy.


4. Reporting problems, making suggestions, submitting code.
-----------------------------------------------------------

Your suggestions, bug reports and contributions of code are always
valued - please do not hesitate to report any problems you may find
(preferably with a fix attached, if you can!).

The preferred method to submit bug reports from a machine with
Internet mail connectivity is to use the send-pr command or use the CGI
script at http://www.freebsd.org/send-pr.html.  Bug reports
will be dutifully filed by our faithful bugfiler program and you can
be sure that we'll do our best to respond to all reported bugs as soon
as possible.  Bugs filed in this way are also visible on our WEB site
in the support section and are therefore valuable both as bug reports
and as "signposts" for other users concerning potential problems to
watch out for.

If, for some reason, you are unable to use the send-pr command to
submit a bug report, you can try to send it to:

                freebsd-bugs@FreeBSD.org

Note that send-pr itself is a shell script that should be easy to move
even onto a totally different system.  We much prefer if you could use
this interface, since it make it easier to keep track of the problem
reports.  However, before submitting, please try to make sure whether
the problem might have already been fixed since.


Otherwise, for any questions or tech support issues, please send mail to:

                freebsd-questions@FreeBSD.org


Additionally, being a volunteer effort, we are always happy to have
extra hands willing to help - there are already far more desired
enhancements than we'll ever be able to manage by ourselves!  To
contact us on technical matters, or with offers of help, please send
mail to:

                freebsd-hackers@FreeBSD.org


Please note that these mailing lists can experience *significant*
amounts of traffic and if you have slow or expensive mail access and
are only interested in keeping up with significant FreeBSD events, you
may find it preferable to subscribe instead to:

                freebsd-announce@FreeBSD.org


All of the mailing lists can be freely joined by anyone wishing
to do so.  Send mail to MajorDomo@FreeBSD.org and include the keyword
`help' on a line by itself somewhere in the body of the message.  This
will give you more information on joining the various lists, accessing
archives, etc.  There are a number of mailing lists targeted at
special interest groups not mentioned here, so send mail to majordomo
and ask about them!
