nginx 0.5.36 release

Changes with nginx 0.5.36                                        04 May 2008

   *) Bugfix: the "sub_filter" directive might set text to change into
      output.

   *) Bugfix: a segmentation fault occurred in worker process, if empty
      stub block was used second time in SSI.

   *) Bugfix: the "proxy_store" and "fastcgi_store" directives did not
      check a response length.

   *) Bugfix: nginx issued the bogus error message "SSL_shutdown() failed
      (SSL: )"; bug appeared in 0.5.35.

   *) Bugfix: in HTTPS mode requests might fail with the "bad write retry"
      error; bug appeared in 0.5.35.

   *) Bugfix: the "fastcgi_catch_stderr" directive did return error code;
      now it returns 502 code, that can be rerouted to a next server using
      the "fastcgi_next_upstream invalid_header" directive.

   *) Bugfix: a segmentation fault occurred in master process if the
      "fastcgi_catch_stderr" directive was used; bug appeared in
      0.5.32.
      Thanks to Manlio Perillo.

Now 0.5.x branch has become legacy and 0.6.x - stable.
