nginx-0.1.38-RELEASE import *) Feature: the "limit_rate" directive is supported in in proxy and FastCGI mode. *) Feature: the "X-Accel-Limit-Rate" response header line is supported in proxy and FastCGI mode. *) Feature: the "break" directive. *) Feature: the "log_not_found" directive. *) Bugfix: the response status code was not changed when request was redirected by the ""X-Accel-Redirect" header line. *) Bugfix: the variables set by the "set" directive could not be used in SSI. *) Bugfix: the segmentation fault may occurred if the SSI page has more than one remote subrequest. *) Bugfix: nginx treated the backend response as invalid if the status line in the header was transferred in two packets; the bug had appeared in 0.1.29. *) Feature: the "ssi_types" directive. *) Feature: the "autoindex_exact_size" directive. *) Bugfix: the ngx_http_autoindex_module did not support the long file names in UTF-8. *) Feature: the IMAP/POP3 proxy.
