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

Wed Mar 15 23:29:59 MSK 2017
	Prevented socket read/write if connection is suspended.
	Added missing resets of 'connection->in_idle'.
	Reworked handling of suspended connection: ensure that
	connection is not disconnected by timeout, always
	updated read/write states right after suspending. -EG

Wed Mar 15 21:02:26 MSK 2017
	Added new enum value MHD_CONNECTION_INFO_CONNECTION_TIMEOUT
	to get connection timeout by MHD_get_connection_info(). -EG

Sat Mar 11 12:03:45 CET 2017
	Fix largepost example from tutorial to properly generate
	error pages. -CG
	Fix largepost example, must only queue replies either before upload
	happens or after upload is done, not while upload is ongoing

Fri Mar 10 16:37:12 CET 2017
	Fix hypothetical integer overflow for very, very large
	timeout values. -CG

Fri Mar 10 16:22:54 CET 2017
	Handle case that we do not listen at all more gracefully

	Updates file `.gitignore`.

Tue Mar  7 10:37:45 BRT 2017
	Updated the MHD_OPTION_URI_LOG_CALLBACK's documentation.

Mon Mar  6 21:46:59 BRT 2017
	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.
	Do not clear 'ready' flag in epoll mode if send()/recv() result is
	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
	Replace tsearch configure check with code from gnulib. -CG

Wed Feb 15 13:35:36 CET 2017
	Fixing a few very rare race conditions for thread-pool or
	thread-per-connection operations during shutdown.
	Various minor cosmetic improvements.
	Fixed #4884 and #4888 (solaris portability issues). -CG

Wed Feb 08 22:33:10 MSK 2016
	Ported test_quiesce_stream to W32.
	Improved precompiler flags selection of OpenBSD.
	Fixed sending responses backed by files not supported by sendfile().
	Fixed thread safety for responses backed by file FD.
	Updated fileserver_example.
	Improved handling of 'upgraded' TLS forwarding in select() and poll()
	modes.
	Fixed processing of incoming TLS data in epoll mode if more than 128
	connections are active.
	Fixed accepting more than 128 incoming connection in epoll mode.
	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.
	Excluded gettext files generation from normal build.
	Removed generated files from GIT. -EG

Tue Nov 15 19:08:43 MSK 2016
	Fixed forwarding "upgraded" TLS connections for
	chunks sizes larger than buffer size. -EG

Mon Nov 14 22:18:30 MSK 2016
	Fixed unintentional usage of SO_REUSEADDR on W32.
	Added support for SO_EXCLBIND on Solaris.
	Fixed using MHD with MHD_OPTION_LISTENING_ADDRESS_REUSE
	on Linux kernels before 3.9 (longterm 3.2 and 3.4
	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.
	Added MHD_USE_AUTO and MHD_USE_AUTO_INTERNAL_THREAD for
	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.
	Added HTTP "Upgrade" example. -CG
