Fri Mar 17 10:45:31 MSK 2017
	If read buffer is full, MHD need to receive remote data and application
	suspended connection, do not fail while connection is suspended and give
	application one more chance to read data from buffer once connection is
	resumed. -EG

Thu Mar 16 23:45:29 MSK 2017
	Allow again to run MHD in external epoll mode by
	MHD_run_from_select() - this allow unification of user code
	and produce no harm for performance. Especially useful with
	MHD_USE_AUTO flag. -EG

Thu Mar 16 23:12:07 MSK 2017
	Idle connection should be disconnected *after* "timeout" number of
	second, not *before* this number. -EG/VT

	Added the i18n example fixing #4924. -SC

Wed Mar 1 23:47:05 CET 2017
	Minor internal optimisations.
	Changed closure connection monitoring logic: now all connections are
	monitored for OOB data (which treated as error), connections are not
	monitored any more for incoming data if incoming data is not required for
	processing. except_fd_set is not optional now for MHD_get_fdset(),
	MHD_get_fdset2() and MHD_run_from_select().
	Improved connection processing in epoll mode: now connection can process
	both read and write each turn.
	Updated HTTP response codes; updated and added all missing standard HTTP
	headers names (and headers categories); updated and added all missing
	standard and additional HTTP methods. Now MHD return status
	MHD_HTTP_REQUEST_HEADER_FIELDS_TOO_LARGE (431) instead of old
	MHD_HTTP_REQUEST_ENTITY_TOO_LARGE (413) for very long header.
	Reworked handling of data pending in TLS buffers, resolved busy-waiting
	if incoming data is pending in TLS buffers and connection is in
	LOOP_INFO_WRITE mode.

	EINTERRUPTED.
	Better detection of unready connection state: used less number of calls of
	recv()/send() in epoll mode.
	Configure: do not run gcrypt and GnuTLS tests if HTTPS is disabled by
	configure parameter.
	Fixed wrong value returned by MHD_get_timeout().
	All double-linked lists now walked from tail to head. As new items are
	added to head, this result in more uniform processing time.
	Improved sockets errors handling in epoll mode.
	OOB data on 'upgraded' sockets is treated as error. -EG

Thu Feb 16 11:20:05 CET 2017

	Improved test_large_put, added poll() and epoll testing.
	Added test_large_put_inc for testing of incremental buffer processing.
	Rewritten epoll connection processing logic: handle all connection one
	time per turn instead of trying to handle all active connection until all
	pending data is dried. Result is more uniform connection processing
	period. -EG

Wed Nov 23 15:24:10 MSK 2016
	Used SO_REUSEADDR (on non-W32) alongside with SO_REUSEPORT if option
	MHD_OPTION_LISTENING_ADDRESS_REUSE was set. -EG

Wed Nov 23 12:48:23 MSK 2016
	Move all gettext-related staff to 'po' subdirectory.

	are still supported). -EG

Sun Nov 13 19:16:38 CET 2016
	Fixed a few race issues on suspend-resume in cases where the
	application uses threads even though MHD did not (or at least
	had no internal need for locking). Also fixed DLL handling of
	the timeout list, avoiding manipulating it for suspended
	connections.  Finally, eliminated calling application logic
	on suspended connections (which before could happen under
	certain circumstances). -CG

Thu Nov 11 20:49:23 MSK 2016
	Added support for various forms of
	pthread_attr_setname_np() so thread names will be set
	more efficiently on certain platforms (Solaris, NetBSD etc.) -EG

Thu Nov 10 21:50:35 MSK 2016
	Added rejection in MHD_start_daemon() of invalid combinations
	of daemon flags.

	automatic selection of polling function depending on
	platform capabilities and requested mode. -EG

Thu Nov 10 17:49:56 MSK 2016
	Ported "upgrade" tests to W32 and other platforms, used
	"gnutls-cli" instead of "openssl" in tests, minor bugs
	fixed, added verbose reporting if requested.
	"Upgrade" processing - changed internal handling logic, improved
	and refactored, bugs fixed, fixed sigpipe on Darwin, added
	printing error to log, fixed compilation without HTTPS.
	Added 'configure' parameter "--disable-httpupgrade" for building
	minimal-sized MHD versions.
	Added feature check "MHD_FEATURE_UPGRADE".
	Responses destroyed (freed) earlier if possible.
	Added many remarks in code comments about thread safety.
	Some data races and other multithread-related issues are fixed,
	including usage of closed sockets (may resulted in accidental closing
	of wrong socket).
	SO_NOSIGPIPE is used on all platform which support it, not only
	on Darwin.
	Added support for suspending connections in thread-per-connection
	mode (itself almost useless, mostly to unify modes support).
	Fixed Inter-Thread Communication channel usage in epoll modes.
	Reworked daemon cleanups and handling MHD_stop_daemon(): resources
	are freed only by specific threads, data races and other fixes.
	Started usage of C99 standard 'bool' where supported with
	fallback to 'int'.
	Renamed many MHD flags. Now they are self-explainable and more
	obvious, like MHD_USE_INTERNAL_POLLING_THREAD instead of
	MHD_USE_SELECT_INTERNALLY. Old flag names are supported for
	backward compatibility.
	Improved processing of "fast" connections: now full sequence
	"read request - send reply headers - send reply body" is processed
	after single select()/poll(). If connection is slow, request is huge
	or response in not immediately ready - connection will be processed
	in "traditional" way.
	Added usage of "calloc()" where supported.
	Minor documentation fixes.
	Minor improvements and fixes. -EG
	"Upgrade" test fixes.
	Documentation updated.

	of communications.
	Optimizations: ITCs now always created in non-blocking mode.
	Added configure parameter to choose ITC type.
	Updated documentation and comments.
	Minor errors fixed (related to heavy load). -EG

Thu Sep 22 17:51:04 CEST 2016

	in `union MHD_ConnectionInfo`.  -MS

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

Sat Aug 27 21:01:43 CEST 2016
	Adding a few extra safety checks around HTTP "Upgrade"
	(against wrong uses of API), and a testcase. -CG

Sat Aug 27 20:07:53 CEST 2016
	Adding completely *untested* logic for HTTP "Upgrade"
	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 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.
