CHANGELOG

Version 1.4.1

Lua 5.3 compatibility (or rather, some cleanup in the number handling department)
socket fd’s are checked against FD_SETSIZE now in select()
changed build type to make
converted all documentation to markdown
fixed bug: send and sendto would not correctly return false on timeout (patch by 云风)

tweaked lsocket.resolve() in order to reduce duplicates.
there is now an experimental asynchronous dns resolver as an additional library included, but that is not an official part of lsocket. Please see doc/README_ARESOLVER in the distribution archive for more infos.
somewhat more thorough check for whether a host address is an ip address, i.e. needs no resolving.
some minor tweaks.

lsocket.connect() is now also nonblocking, apart from nameserver lookups.
socket:status() method added to query sockets for errors (necessary because of non-blocking connect(), but also handy for other situations)
nicer SIGPIPE handling, using socket or send options where possible, and disabling SIGPIPE for the send/sendto operation only where options are not available.
the included rshttpd.lua example httpd library now supports keepalive connections.

just 2 more examples, one http client and one http server, to illustrate the hoops you have to jump through in order to take advantage of the non- blocking nature of lsocket.

enhance check of whether a nslookup is needed, should now cover all cases
modified select() to ignore closed sockets, also calling select() without open sockets and without timeout is now an error (instead of blocking forever).
added constant _VERSION, which contains the full version number for lsocket.
fixed an issue that would keep the Mac’s from compiling this
some cleanup in the 5.1/5.2 compatibility department as suggested by lhf
