Changelog
---------

(development since 1.1....)

User api additions
------------------

 - lws_get_library_version() returns a const char * with a string like
 	 "1.1 9e7f737", representing the library version from configure.ac
	 and the git HEAD hash the library was built from


User api changes
----------------

 - Header tokens are now deleted after the websocket connection is
 established.  Not just the header data is saved, but the pointer and length
 array is also removed from (union) scope saving several hundred bytes per
 connection once it is established


New features
------------

Cmake project file added, aimed initially at Windows support: this replaces
the visual studio project files that were in the tree until now.



v1.1-chrome26-firefox18

user api changes
----------------

 - libwebsockets_serve_http_file() now takes a context as first argument

 - libwebsockets_get_peer_addresses() now takes a context and wsi as first
	two arguments


user api additions
------------------

 - lwsl_...() logging apis, default to stderr but retargetable by user code;
	may be used also by user code

 - lws_set_log_level() set which logging apis are able to emit (defaults to
	notice, warn, err severities), optionally set the emit callback

 - lwsl_emit_syslog() helper callback emits to syslog

 - lws_daemonize() helper code that forks the app into a headless daemon
	properly, maintains a lock file with pid in suitable for sysvinit etc to
	control lifecycle

 - LWS_CALLBACK_HTTP_FILE_COMPLETION callback added since http file
	transfer is now asynchronous (see test server code)

 - lws_frame_is_binary() from a wsi pointer, let you know if the received
	data was sent in BINARY mode


user api removals
-----------------

 - libwebsockets_fork_service_loop() - no longer supported (had intractable problems)
	arrange your code to act from the user callback instead from same
	process context as the service loop

 - libwebsockets_broadcast() - use libwebsocket_callback_on_writable[_all_protocol]()
	instead from same process context as the service loop.  See the test apps
	for examples.

 - x-google-mux() removed until someone wants it

 - pre -v13 (ancient) protocol support removed


New features
------------

 - echo test server and client compatible with echo.websocket.org added

 - many new configure options (see README.build) to reduce footprint of the
	library to what you actually need, eg, --without-client and
	--without-server

 - http + websocket server can build to as little as 12K .text for ARM

 - no more MAX_CLIENTS limitation; adapts to support the max number of fds
	allowed to the process by ulimit, defaults to 1024 on Fedora and
	Ubuntu.  Use ulimit to control this without needing to configure
	the library.  Code here is smaller and faster.

 - adaptive ratio of listen socket to connection socket service allows
	good behaviour under Apache ab test load.  Tested with thousands
	of simultaneous connections

 - reduction in per-connection memory footprint by moving to a union to hold
	mutually-exclusive state for the connection

 - robustness: Out of Memory taken care of for all allocation code now

 - internal getifaddrs option if your toolchain lacks it (some uclibc)

 - configurable memory limit for deflate operations

 - improvements in SSL code nonblocking operation, possible hang solved,
	some SSL operations broken down into pollable states so there is
	no library blocking, timeout coverage for SSL_connect

 - extpoll test server merged into single test server source

 - robustness: library should deal with all recoverable socket conditions

 - rx flowcontrol for backpressure notification fixed and implmeneted
	correctly in the test server

 - optimal lexical parser added for header processing; all headers in a
	single 276-byte state table

 - latency tracking api added (configure --with-latency)

 - Improved in-tree documentation, REAME.build, README.coding,
	README.test-apps, changelog

 - Many small fixes
