Heres the info:
The ds wifi library has a new release and is now available from sourceforge. This will also be included with the soon to be available devkitPro Updater 1.3.5.
The following items have been significantly improved or resolved since the 0.3 release (this is a rough list, mostly taken from a list of outstanding issues that have all been addressed now)
gethostbyname has problems with IP addresses (fixed, awaiting release)
wifi_lib_test tcp connection bug (fixed, awaiting release)
misc other berkley-like support that's missing in the current version.
(getsockname/getpeername) (fixed, awaiting release)
Internal TCP Error possibly causing loss of data (fixed, awaiting release)
Better access to stats (done, awaiting release)
"keepalive" message to ensure AP connection remains open (done, awaiting release)
Improved syncookie implementation for more reliable incoming connections
modified timeout code to use exponential backoff
inet_addr support added
TCP connection closing errors (probably fixed)
TCP loses data apparently when rx buffer is filled (fixed)
Latency issue, something is causing the lib to have higher pings after a while (fixed)
possible bug with recv not returning data it should (fixed)
Problem with DHCP (should be fixed, it's possible some routers still deny DHCP - if you have one that does this please let sgstair know)
Connect() now blocks, when socket is not in non-blocking mode
select() support that should be sufficient for all applications is in CVS. (partly done, next release)
TCP MSG_PEEK support added for recv();
Shared key authentication
many TCP speedups and optimizations
