4Version 1.0: August 11, 1996 (cjm)
5
6Version 1.1:  August 20, 1996  (cjm)
7    - Host accepts incoming connections for ports 0 to 1023.
8
9Version 1.2:  September 7, 1996 (cjm)
10    - Fragment handling error in alias_db.c corrected.
11
12Version 1.3:  September 15, 1996 (cjm)
13    - Generalized mechanism for handling incoming
14      connections (no more 0 to 1023 restriction).
15
16    - Increased ICMP support (will handle traceroute now).
17
18    - Improved TCP close connection logic.
19
20Version 1.4: September 16, 1996 (cjm)
21
22Version 1.5: September 17, 1996 (cjm)
23    - Corrected error in handling incoming UDP packets
24      with zero checksum.
25
26Version 1.6: September 18, 1996
27    - Simplified ICMP data storage.  Will now handle
28      tracert from Win95 and NT as well as FreeBSD
29      traceroute, which uses UDP packets to non-existent
30      ports.
31
32Version 1.7: January 9, 1997 (cjm)
33    - Reduced malloc() activity for ICMP echo and
34      timestamp requests.
35
36    - Added handling for out-of-order IP fragments.
37
38    - Switched to differential checksum computation
39      for IP headers (TCP, UDP and ICMP checksums
40      were already differential).
41
42    - Accepts FTP data connections from other than
43      port 20.  This allows one ftp connections
44      from two hosts which are both running packet
45      aliasing.
46
47    - Checksum error on FTP transfers.  Problem
48      in code located by Martin Renters and
49      Brian Somers.
50
51Version 1.8: January 14, 1997 (cjm)
52    - Fixed data type error in function StartPoint()
53      in alias_db.c (this bug did not exist before v1.7)
54      Problem in code located by Ari Suutari.
55
56Version 1.9: February 1, 1997 (Eivind Eklund <perhaps@yes.no>)
57    - Added support for IRC DCC (ee)
58
59    - Changed the aliasing routines to use ANSI style
60      throughout (ee)
61
62    - Minor API changes for integration with other
63      programs than PPP (ee)
64
65    - Fixed minor security hole in alias_ftp.c for
66      other applications of the aliasing software.
67      Hole could _not_ manifest in ppp+pktAlias, but
68      could potentially manifest in other applications
69      of the aliasing. (ee)
70
71    - Connections initiated from packet aliasing
72      host machine will not have their port number
73      aliased unless it conflicts with an aliasing
74      port already being used. (There is an option
75      to disable this for debugging) (cjm)
76
77    - Sockets will be allocated in cases where
78      there might be port interference with the
79      host machine.  This can be disabled in cases
80      where the ppp host will be acting purely as a
81      masquerading router and not generate any
82      traffic of its own.
83      (cjm)
84
85Version 2.0: March, 1997 (cjm)
86    - Aliasing links are cleared only when a host interface address
87      changes.
88
89    - PacketAliasPermanentLink() API added.
90
91    - Option for only aliasing private, unregistered
92      IP addresses added.
93
94    - Substantial rework to the aliasing lookup engine.
95
96Version 2.1: May, 1997 (cjm)
97    - Continuing rework to the aliasing lookup engine
98      to support multiple incoming addresses and static
99      NAT.  PacketAliasRedirectPort() and
100      PacketAliasRedirectAddr() added to API.
101
102    - Now supports outgoing as well as incoming ICMP
103      error messages.
104
105Version 2.2: July, 1997 (cjm)
106    - Rationalized API function names to all begin with
107      "PacketAlias..."  Old function names are retained
108      for backwards compatibility.
109
110    - Packet aliasing engine will now free memory of
111      fragments which are never resolved after a timeout
112      period.  Once a fragment is resolved, it becomes
113      the users responsibility to free the memory.
114
115Version 2.3: August 11, 1997 (cjm)
116    - Problem associated with socket file descriptor
117      accumulation in alias_db.c corrected.  The sockets
118      had to be closed when a binding failed.  Problem
119      in code located by Gordon Burditt.
120
121Version 2.4: September 1, 1997 (cjm)
122    - PKT_ALIAS_UNREGISTERED_ONLY option repaired.
123      This part of the code was incorrectly re-implemented
124      in version 2.1.
125
126Version 2.5: December, 1997 (ee)
127    - Added PKT_ALIAS_PUNCH_FW mode for firewall
128      bypass of FTP/IRC DCC data connections.  Also added
129      improved TCP connection monitoring.
130
131Version 2.6: May, 1998 (amurai)
132    - Added supporting routine for NetBios over TCP/IP.
133
134Version 3.0: January 1, 1999
135    - Transparent proxying support added.
136    - PPTP redirecting support added based on patches
137      contributed by Dru Nelson <dnelson@redwoodsoft.com>.
138
139Version 3.1: May, 2000 (Erik Salander, erik@whistle.com)
140    - Added support to alias 227 replies, allows aliasing for
141      FTP servers in passive mode.
142    - Added support for PPTP aliasing.
143
144Version 3.2: July, 2000 (Erik Salander, erik@whistle.com and
145      Junichi Satoh, junichi@junichi.org)
146    - Added support for streaming media (RTSP and PNA) aliasing.
