[lwip-users] [lwip] Version 0.5.1 released

[Adam Dunkels]

Hi all!

Version 0.5.1 is now released. This is mainly a bugfix release incorporating 
all changes that have been discussed on the list (including the latest 
api_lib.c bug). Being in a slight hurry to start watching Sweden's first 
ice-hockey match in the olympic games (against Canada), I don't have much 
time for a long announment ;-)

Big thanks goes out to all of you who have contributed code, patches, 
comments, bugfixes, bug reports, both on this list and privately to me. Leon, 
Jose, Kieran, Horst, Biren, Florian, Andy, Andrea, Paul, and all others: 
thanks!

Unfortunately, this release doesn't incorporate Leon's DHCP code. That will 
hopefully be integrated with the next version. Until then, his code can be 
downloaded and integrated "by hand".

(I also have a few mails in my inbox that I won't be able to answer in a 
while - please bear with me!)

The changelog for this release is as follows:

  ++ Other changes:
