  * Add thread local storage support to {{{Lwt}}}

    be recored by using the syntax extension with the {{{-lwt-debug}}}
    command line switch.
  * Allow blocking system calls to be executed in parallels
  * Change the type of many functions of {{{Lwt_unix}}}, which now
    return a {{{Lwt}}} thread

  * Add functions {{{Lwt_event.delay}}} and {{{Lwt_signal.delay}}}
  * Add function {{{Lwt_term.render_update}}}
  * Add function {{{Lwt_ssl.embed_socket}}}
  * Add module {{{Lwt_bytes}}} defining operations on bigarrays
    instead of strings
  * Use bigarrays in Lwt_io instead of strings for the internal buffer.
    Lwt_io.make now takes a function that uses a bigarray.
  * Add module {{{Lwt_switch}}}

Enjoy!
