Note: Please send bug-report/bug-fixes/new module addition to [e-mail]

********
v2.11:   
********
Bug Fixes:
1. Fixed dhcp.c to make it work with new C18 startup code.

Improvements:
1. Modified websrvr.c DownloadMPFS() to make use of compiler allocated XMODEM data block
   rather than use fixed address block starting at 0x400.


********
v2.10:   7/9/02
********
Bug Fixes:
1. Fixed HTTP Server bug where a form submission with empty parameter value would not 
   parse correctly.



********
v2.0:   5/22/02
********

********
New Modules:
********
1. Added UDP, DHCP, FTP and IP Gleaning
2. Added PICDEM.net LCD support
3. Added board setup through RS-232.

********
Improvements:
********
1. Optimized serial EEPROM access routines in terms of speed and size
    (Replaced ee256.* files with eeprom*.h)
2. Improved board setup through RS-232.

********
Known Issues:
********
1. LCD may not display properly on MCLR only.
   Workaround: 1. Debug XLCDInit() routine in "xlcdlh" 
               2. Always do POR reset.

2. SLIP connection is not very robust.
   Workaround: None at this time.

3. Hi-Tech Compiler: 
                1. Aggressive optimization breaks the functionality.
                   Workaround: Apply optimization listed in each source file comment header.
                2. In order to use V8.12, you will need to remove "FTP Server" from Ht*.pjt.
                   You will also need to disable all optimizations.

4. C18 Compler: 1. Static model does not compile.
                   Workaround: None at this time.
                2. Overlay model breaks the functionality.
                   Workaround: None at this time.
                3. All modules does not fit in 32KB memory.
                   Workaround: 1. None at this time.
                               2. Sample project disables some modules.
