Subject: Changes with nginx 0.1.1                                         11
 Oct 2004

    *) Feature: the gzip_types directive.

    *) Feature: the tcp_nodelay directive.

    *) Feature: the send_lowat directive is working not only on OSes that
       support kqueue NOTE_LOWAT, but also on OSes that support SO_SNDLOWAT.

    *) Feature: the setproctitle() emulation for Linux and Solaris.

    *) Bugfix: the "Location" header rewrite bug fixed while the proxing.

    *) Bugfix: the ngx_http_chunked_module module bug fixed that caused an
       endless loop.

    *) Bugfix: the /dev/poll module bugs fixed.

    *) Bugfix: the responses were corrupted when the temporary files were
       used while the proxing.

    *) Bugfix: the unescaped requests were passed to the backend.

    *) Bugfix: while the build configuration on Linux 2.4 the
       --with-poll_module parameter was required.
