nginx 0.5.36 *) 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.
