nginx 0.7.53 *) Change: now a log set by --error-log-path is created from the very start-up. *) Feature: now the start up errors and warnings are outputted to an error_log and stderr. *) Feature: the empty --prefix= configure parameter forces nginx to use a directory where it was run as prefix. *) Feature: the -p switch. *) Feature: the -s switch on Unix platforms. *) Feature: the -? and -h switches. Thanks to Jerome Loyet. *) Feature: now switches may be set in condensed form. *) Bugfix: nginx/Windows did not work if configuration file was given by the -c switch. *) Bugfix: temporary files might be not removed if the "proxy_store", "fastcgi_store", "proxy_cache", or "fastcgi_cache" were used. Thanks to Maxim Dounin. *) Bugfix: an incorrect value was passed to mail proxy authentication server in "Auth-Method" header line; the bug had appeared in 0.7.34. Thanks to Simon Lecaille. *) Bugfix: system error text descriptions were not logged on Linux; the bug had appeared in 0.7.45. *) Bugfix: the "fastcgi_cache_min_uses" directive did not work. Thanks to Andrew Vorobyoff.
