nginx-0.1.1-RELEASE import *) 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 proxying. *) Bugfix: the ngx_http_chunked_module module may get caught in an endless loop. *) Bugfix: the /dev/poll module bugs fixed. *) Bugfix: the responses were corrupted when the temporary files were used while the proxying. *) 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.
