annotate src/core/ngx_crc32.h @ 491:392c16f2d858 NGINX_0_7_53
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.
