+
+ * Added SILC Timer API to lib/silcutil/silctimer.[ch],
+ silctimer_i.h, tests/test_silctimer.c.
+
Tue Jul 10 20:02:04 EEST 2007 Pekka Riikonen <priikone@silcnet.org>
* Added queue entry free list to thread pool instead of
lib/silcclient, The Client Library
==================================
+ o UDP SILC connection support to SILC server
+
o Giving WHOIS for nick that doesn't exist should remove any same
named entries from the client cache.
o Structured log messages to Log API. Allows machine readable log
messages. Would allow sending of any kind of data in a log message.
- o Base64 to an own API
+ o Base64 to an own API (***DONE)
- o Timer API
+ o Timer API (***DONE)
o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
o Library must have support for SERVICE command.
+ o Both UDP and TCP support for incoming connecetions. Maintaining long
+ term UDP sessions.
+
o The server must be able to run behind NAT device. This means that
Server ID must be based on public IP instead of private IP.
