1.35 sobrado 32: (i.e., these are the changes people ask about most often). Machine
1.1 deraadt 33: specific changes have also been made, and are sometimes mentioned
1.35 sobrado 34: in the pages for the specific <a href=plat.html>platforms</a> if you
1.1 deraadt 35: are interested in further port-specific details. Many ports
36: have had architecture-specific enhancements relative to NetBSD,
37: but when they do not they certainly have plenty of platform-independent

1.65 bentley 106: <h3>Changes made between birth and OpenBSD 2.0</h3>
1.49 deraadt 107: <p>
108:
1.1 deraadt 109: <ul>
110: <li>CTM is now a supported way of obtaining OpenBSD source code.
111: <li>Added sudo (which is maintained by one of our developers)
112: <li>Working Linux ext2fs.
113: <li>We have completed security reviews of almost all userland programs and libraries except for the gnu stuff (where, based on preliminary inspection there is poor handling of temp files).
114: <li>FreeBSD's adduser(8) command. Also an rmuser(8) command.
115: <li>A 7% reduction in size of static binaries.
116: <li>Compile time option to compile the source tree almost completely dynamic.
117: <li>Almost a hundred more security fixes, including /tmp races because of strncpy.
118: <li>Another kerberos security fix.
119: <li>deal with the SYN bomb problem (denial of service attack) as well known.
120: <li>less version 2.90
121: <li>mopd for networking booting Digital machines
122: <li>latest GNU groff, incorporated in a clean wrapperized form.
123: <li>secure multicast tools against possible security problems.
1.24 deraadt 124: <li>sendmail gecos hole fixed (in a number of ways; other programs in the source tree were also vulnerable).
1.1 deraadt 125: <li>Nice sample files in /etc
126: <li>16 partitions working on sparc and i386 (yipee!)
127: <li>vim is replacing nvi, since nvi does not have a pure BSD license, and vim also works better.
128: <li>And of course... more security related bugfixes... (ie. dump, restore, mt).
1.4 rohee 129: <li>ftp command modified for easily scripted ftp & http downloads.
1.1 deraadt 130: <li>Complete in-tree development for MIPS/Alpha systems (ie. binutils).
131: <li>New routed from SGI.
132: <li>*Hobbit*'s netcat utility. The crackers use it, so should you.
133: <li>Say goodbye to dump, restore, and mt security holes: They are no longer setuid.
134: <li>DDB can now access symbol tables from LKM modules
135: <li>Some serial driver support for /dev/cuaXX devices to support transparent out+dial
136: <li>FreeBSD pipe() system call; quite a bit faster.
137: <li>libgnumalloc is gone; our malloc() is better.
138: <li>Kernel warns if /dev/console does not exist; nice warning for booting with an unpopulated /dev directory.
