+
+0.8.29 (000323)
++ stable(?) release
+
+
+0.8.28 (000323)

++ break down dhcpd.c into manageable files
+
+
+0.8.27 (000221)

++ multiple DNS now handled from resolv.conf if available
++ multiple WINS (from dhcpd.conf)
+
+0.8.25 (000120)

+	tested with a windows 98 client and the sample config
+	files in the samples directory.
+
+0.8.24 (000117)
++ makeiplist tool has basic functionality in place
++ new sample config files
++ route add -host 255.255.255.255 dev eth0 added for generic linux

++ now sends the correct server ip instead of hardcoded value
++ minor debugging fixes for critical messages
+
+0.8.20 (000106)
++ cut out dhcp server checking.. this was causing dialout ppp
+	sessions with idle time set to never time out.
++ also removed the 10 second pause before launching.. as this
+	was originally to stop it replying to a dhcp client
+	on a NETtel which was really a bad way to do it in the
+	first place :-)
+
+0.8.19 (000104)
++ fixes for route add -host on a machine that needs to run both
+	a DHCP client and server (dual eth box)
+
+0.8.18 (991220)
+
++ Race conditions fixed by disabling alarm whilst the server is busy
++ Fixed continous clearing of the offered array so that it is only cleared

++ added lease time to ACK -- doesn't work if in OFFER
++ decreased internal array clear delay to 60 seconds
