+Released GNU libmicrohttpd 0.9.74
+
+    This release brings a lot of fixes and improvements, and
+    important new features.
+    The most significant addition is the new experimental
+    implementation of WebSockets contributed by David Gausmann. This
+    implementation is not fully tested yet so currently it is disabled
+    by default.
+    Other changes include a lot of improvements and clarifications
+    in doxy comments in microhttpd.h header file, improved compliance
+    with the RFC HTTP specifications, the new implementation of reply
+    header forming, the new implementation of request chunked encoding
+    parsing, new automatic error replies, internal optimisations, and
+    many important fixes, including fixes for long-standing bugs.
+
+    More detailed list of notable changes:
+
+    API changes:
+    + Added new function MHD_get_reason_phrase_len_for().
+    + Added MHD_CONNECTION_INFO_HTTP_STATUS type of information
+      queried by MHD_get_connection_info().
+    + Added new response flag MHD_RF_SEND_KEEP_ALIVE_HEADER to force
+      sending of "keep-alive" header even if not required by RFC.
+    + Added new response creation function
+      MHD_create_response_from_buffer_with_free_callback_cls() with
+      custom cleanup callback.
+    + Added new response flag MHD_RF_HTTP_1_0_COMPATIBLE_STRICT with
+      the same functionality as existing MHD_RF_HTTP_VERSION_1_0_ONLY
+      flag. The old flag will be deprecated.
+    + Added new response flag MHD_RF_HTTP_1_0_SERVER with the same
+      functionality as existing MHD_RF_HTTP_VERSION_1_0_RESPONSE flag.
+      The old flag will be deprecated.
+
+    New features:
+    + Added experimental WebSockets extension with separate header.
+      Disabled by default as it is not fully tested yet.
+    + Added '--enable-sanitizers[=address,undefined,leak,user-poison]'
+      configure parameter (instead of '--enable-sanitizer'),
+      implemented custom memory poisoning for memory pools.
+
+    Improvements and enhancements:
+    * Doxy function descriptions was corrected, clarified, extended,
+      and improved. Now it should be much easier to learn MHD just by
+      reading the headers.
+    * Completely rewritten reply header forming. New implementation is
+      more robust, simpler maintainable and expandable, and better
+      follows RFC HTTP specifications.
+    * Performance improvements: now HTTP version and request method are
+      decoded one time only (previously MHD used string comparison many
+      times during processing the data).
+    * Rewritten request chunked payload decoding. The new
+      implementation better conforms to the HTTP RFC, detects format
+      problems earlier, replies to the clients with description of
+      detected problems, handles untypical (but syntactically correct)
+      values properly.
+    * Added special replies for wrong/unsupported HTTP versions in
+      requests, broken HTTP chunked encoding in requests,
+    * As required by HTTP RFC, added automatic error replies if client
+      used broken chunked encoding, too large chunk size, too large
+      payload size, or broken Content-Length header.
+    * Optimized connection's memory pool handling.
+    * Changed timeout precision from one second to one millisecond.
+    * Added some checks for incorrect user data, reporting problems in
+      MHD log.
+    * Improved performance of hash calculations functions by using
+      compiler built-ins (if available).
+    * Implemented SHA-1 calculations (required for WebSockets).
+    * Added universal MSVC project that works with any (sufficiently
+      new) version of MSVC.
+    * Developed simple HTTP client to test MHD under very special
+      conditions.
+    * Implemented 45 new tests.
+    * Improved existing tests to test more aspects of MHD.
+    * Added check for correct results of system and libcurl functions.
+    * Response headers are checked during forming of responses.
+    * HTTPS tests were improved.
+    * Added rebuild on W32 of all required files if files are missing.
+    * Many internal optimisations and improvements.
+
+    Functionality changes:
+    * Keep-alive header is omitted by default for HTTP/1.1 connections.
+      Use of header can be enforced by response flag.
+    * Chunked encoding is used for HTTP/1.1 non-keep-alive connections
+      for responses with unknown size. Previously MHD used "indication
+      of the end of the response by closing connection" in such cases,
+      however it is not correct for HTTP/1.1 connections as per HTTP
+      RFC.
+    * As required by HTTP RFC, use HTTP/1.1 version instead of HTTP/1.0
+      in reply headers when client is HTTP/1.0 . HTTP/1.0 version can
+      be enforced by response flag.
+    * User response headers are used in replies in the same order as
+      was added by application.
+    * Allowed tab characters in response header values.
+    * All custom "Connection:" response headers are automatically
+      combined into single "Connection:" header.
+    * "keep-alive" token silently dropped from custom "Connection:"
+      response header. "Keep-alive" cannot be enforced and used
+      automatically if possible.
+    * Allow tab character in custom response header value.
+    * Disallow space character in custom response header value.
+    * Do not allow responses with 1xx codes for HTTP/1.0 requests.
+    * Detected and reported incorrect "Upgrade" responses.
+    * W32 targets are changed to Vista+ by default. XP is supported
+      still.
+
+    Fixes:
+    # Fixed short busy-waiting (up to one second) when connection is
+      going to be expired and closed.
+    # Fixed handling of errors during start of new connection, fixed
+      inability to accept new connections in thread-per-connection mode
+      due to the missing decrement of number of daemon's connections if
+      start of new thread is failed.
+    # Fixed incorrect parsing of LFLF, LFCR, CRCR, and bare CR as
+      single linefeed in request header and request chunked payload.
+      Now only CRLF or bare LF are recognized as linefeed.
+    # Fixed response chunked encoding handling. Now it works properly
+      with non-keep-alive connection, with fixed size replies (if
+      chunked was enforced by header), and in other situations.
+    # Other fixes for chunked replies.
+    # Fixed handling of custom connection timeout in thread-per-
+      connection mode.
+    # Fixed wrongly used MHD_REQUEST_TERMINATED_COMPLETED_OK code for
+      application notification when MHD_REQUEST_TERMINATED_WITH_ERROR
+      code must be used.
+    # Fixed code MHD_REQUEST_TERMINATED_READ_ERROR not reported (code
+      MHD_REQUEST_TERMINATED_WITH_ERROR was incorrectly used instead).
+    # Fixed handling of request chunked encoding with untypical
+      formatting.
+    # Fixed processing of last part of hex-encoded values under
+      certain conditions.
+    # Fixed value returned for MHD_CONNECTION_INFO_REQUEST_HEADER_SIZE.
+    # Fixed returned value for MHD_FEATURE_AUTOSUPPRESS_SIGPIPE on W32,
+      now it is MHD_YES as W32 does not need SIGPIPE suppression.
+    # Fixed portability of bitwise NOT for enums values.
+    # Fixed SHA-256 and MD5 calculations with unaligned data.
+    # Fixed incorrect caseless matching for HTTP version.
+    # Fixed incorrect caseless matching for request method.
+    # Fixed compatibility with old GnuTLS versions.
+    # Fixed compiler warnings on 32-bits platforms.
+    # Fixed blocking sockets setting in tests and examples for W32.
+    # Fixed examples to really use libmagic if present.
+    # HTTPS tests were fixed.
+    # Fixed libcurl test with case-insensitive match for HTTP methods,
+      method names must use case-sensitive match.
+    # Fixed tests compatibility with old libcurl versions.
+    # Fixed build on W32 with llvm-dlltool (this tool is too 
+      oversimplified)
