Tue Oct 11 18:14:40 MSK 2016
	Code internal refactoring: 'pipes' renamed to 'inter-thread
	communication (channels)/ITCs', as code can use different types
	of communications.

	Minor errors fixed (related to heavy load). -EG

Thu Sep 22 17:51:04 CEST 2016

Sun Sep  4 18:16:32 CEST 2016
	Fixing potential memory leak (#4634). -CG

Sun Sep  4 17:25:45 CEST 2016

	mode. Also still untested. -CG

	handling. -CG

	Releasing libmicrohttpd 0.9.51. -CG

Tue Aug 23 22:54:07 MSK 2016
	Internal refactoring: W32 compatibility layer was finally
	replaced with several specialized abstraction layers for
	sockets, control pipes (inter-thread communication) and
	generic functions. Now all major platform functions
	(including threads and mutex) are implemented in thin
	abstraction layers.
	Improved performance on W32 due to eliminating
	translation of error to POSIX codes and using W32 codes
	directly (through macros).
	Improved error reporting on all platforms.
	Improved error handling and reporting on Darwin.
	Minor fixes. -EG

Tue Aug 16 15:14:30 MSK 2016
	Minor improvement for monotonic clock.
	Minor configure fix for non-bash shells. -EG

Mon Aug 15 13:06:52 CEST 2016
	Fixed possible crash due to write to read-only region of
	memory given ill-formed HTTP request (write was otherwise
	harmless, writing 0 to where there was already a 0).
	Fixed issue with closed connection slots not immediately
	being available again for new connections if we reached
	our connection limit.
	Avoid even accept()ing connections in certain thread modes
	if we are at the connection limit and
	MHD_USE_PIPE_FOR_SHUTDOWN is available. -CG

Wed Aug 10 16:42:57 MSK 2016
	Moved threads, locks and mutex abstraction to separate files,
	some minor errors fixed, added support for thread name functions
	on various platforms, added configure flag for disable thread
	naming. -EG

Sat Jul 23 20:45:51 CEST 2016
	Added macro detection of speed/size compiler optimization.
	Added different implementation of functions in mhd_str.c for
	size optimization. Enabled automatically if compiler size
	optimization is detected or MHD_FAVOR_SMALL_CODE is defined.
	Added unit tests for all mhd_str.c functions. -EG

Sat Jul 16 21:54:49 CEST 2016
	Warn user if they sent connection into blocking
	state by not processing all POST data, not suspending,
	and not running in external select mode. -CG

Fri Jul  8 21:35:07 CEST 2016
	Fix FIXME in tutorial. -CG

Fri Jul  8 15:57:06 CEST 2016
	Adding support for 308 status code. -CG

Sat Jun 25 13:49:31 CEST 2016

	Do not send "Content-Length" header for 1xx/204/304 status codes. -CG

Tue May 17 13:32:21 CEST 2016
	Allow clients to determine whether a connection is suspended;
	introduces MHD_CONNECTION_INFO_CONNECTION_SUSPENDED. -CG/FC

Sun May 15 12:17:25 CEST 2016
	Fix handling system or process resource limit exhaustion upon
	accept(). -CG/CP

Thu May 12 08:42:19 CEST 2016
	Fix handling of partial writes in MHD_USE_EPOLL_LINUX_ONLY; only
	consider sockets returning EAGAIN as unready. -CG/CP

Mon May  2 06:08:26 CEST 2016
	Adding logic to help address FE performance issue as
	discussed on the mailinglist with subject
        "single-threaded daemon, multiple pending requests, responses \ 
batched".
	The new logic is only enabled when MHD_USE_EPOLL_TURBO is set.
	Note that some additional refactoring was also done to clean up
	the code and avoid code duplication, which may have actually fixed
	an unrelated issue with HTTPS and a POLL-style event loop. -CG

Sat Apr 30 10:22:37 CEST 2016
	Added clarifications to manual based on questions on list. -CG

Sat Apr 23 20:12:01 CET 2016

	on Darwin without "MHD_USE_PIPE_FOR_SHUTDOWN" option. -EG
