+* Version 0.1
+
+	Initial version of natd.
+
+* Version 0.2
+
+	- Alias address can now be set by giving interface name with 
+	  new (-n) command-line option.
+
+	- New Makefile based on bsd.prog.mk.
+	  
+	- Error messages are written to syslog
+	  after natd has become a daemon.
+
+* Version 1.0
+
+	- Support for using only single socket (-p option)
+
+* Version 1.1
+
+	- -a option now understands a hostname also.
+	- -a option no longer dumps core.
+	- Packet aliasing software upgraded to v. 1.9
+  	- added long option names (like -address)
+
+* Version 1.2
+
+	- Fixed core dump with -port option.
+	- Added -Wall to CFLAGS and some headers added to natd.c
+	  to get clean compile by Brian Somers [brian@awfulhak.org].
+
+* Version 1.3
+
+	- Aliasing address initialization is delayed until first
+	  packet arrives. This allows natd to start up before
+	  interface address is set.
+	- SIGTERM is now catched to allow kernel to close
+	  existing connections when system is shutting down.
+	- SIGHUP is now catched to allow natd to refresh aliasing
+	  address from interface, which might be useful to tun devices.
+
+* Version 1.4
+
+	- Changed command line options to be compatible with
+	  command names used in ppp+packetAlias package (which is the
+	  original application using aliasing routines). 
+
+	  The options which map directly to packet aliasing options are:
+
+		-unregistered_only [yes|no]
+		-log [yes|no]
+		-deny_incoming [yes|no]
+		-use_sockets [yes|no]
+		-same_ports [yes|no]
+
+	  The short option names are the same as in previous
+	  releases.
+
+	- Command line parser rewritten to provide more flexible
+	  way to support new packet aliasing options.
+
+	- Support for natd.cf configuration file has been added.
+	  
+	- SIGHUP no longer causes problems when running without
+	  interface name option.
+
+	- When using -interface command line option, routing socket
+	  is optionally listened for interface address changes. This
+	  mode is activated by -dynamic option.
+
+	- Directory tree reorganized, alias package is now a library.
+
+	- Manual page written by Brian Somers <brian@awfulhak.org> added.
+	- README file updated.
+
+* Version 1.5
+
+	- Support for sending ICMP 'need fragmentation' messages
+ 	  when packet size exceeds mtu size of outgoing network interface.
+
+	- ipfw rule example in manual page fixed.
+
+* Version 1.6
+
+	- Upgrade to new packet aliasing engine (2.1)
+	- redirect_port and redirect_address configuration
+	  parameters added.
+	- It is no longer necessary to quote complex parameter values
+	  in command line.
+	- Manual page fixed (same_port -> same_ports).
+
+* Version 1.7
+
+	- A bug in command-line parsing fixed (it appeared due
+	  to changes made in 1.6).
+
+* Version 1.8
+
+	- Fixed problems with -dynamic option.
+	- Added /var/run/natd.pid
+
+* Version 1.9
+
+	- Changes to manual page by
+	  Brian Somers <brian@awfulhak.org> integrated.
+	- Checksum for incoming packets is always recalculated
+	  for FreeBSD 2.2 and never recalculated for newer
+	  versions. This should fix the problem with wrong
+ 	  checksum of fragmented packets.
+	- Buffer space problem found by Sergio Lenzi <lenzi@bsi.com.br>
+	  fixed. Natd now waits with select(2) for buffer space
+	  to become available if write fails.
+	- Packet aliasing library upgraded to 2.2.
