Dear all,

I'm glad to announce the release of GNU libmicrohttpd 0.9.72.
This release is mostly bugfix release, with greatly improved compatibility with various OSes/kernels, including FreeBSD, Windows, OpenBSD, NetBSD, Darwin (macOS), Solaris. Performance is improved, especially with stay-alive HTTP and HTTPS connections.

Notable changes since version 0.9.71:
+ New function MHD_create_response_from_pipe().
* Fully rewritten code for buffering/pushing from kernel network buffers
  for compatibility with various OSes. Reduced number of additional
  sys-calls, network is better utilized, responses are delivered faster.
  Restored optimal sendfile() usage on FreeBSD.
* MHD now takes care about SIGPIPE handling by blocking it in internal
  threads and avoiding functions (like sendfile()) that could generate
  SIGPIPE when blocking of this signal is not possible.
* Fixed crash in PostProcessor.
* Fixed several resources leaks in corner cases.
* Improved thread sync, thread safety and fixed one use-after-free under
  special conditions during stopping of daemon.
* Updated HTTP status codes, header names and methods from the
* Fixed functioning without listen socket and with internal threads.
* Fixed streaming of chunked responses for both HTTP and HTTPS.
* Various compatibility fixes.
