nginx 0.6.32 *) Change: the "none" parameter in the "ssl_session_cache" directive; now this is default parameter. Thanks to Rob Mueller. *) Change: now the 0x00-0x1F, '"' and '\' characters are escaped as \xXX in an access_log. Thanks to Maxim Dounin. *) Change: now nginx allows several "Host" request header line. *) Feature: the "modified" flag in the "expires" directive. *) Feature: the $uid_got and $uid_set variables may be used at any request processing stage. *) Feature: the $hostname variable. Thanks to Andrei Nigmatulin. *) Feature: DESTDIR support. Thanks to Todd A. Fisher and Andras Voroskoi. *) Bugfix: if sub_filter and SSI were used together, then responses might were transferred incorrectly. *) Bugfix: large SSI inclusions might be truncated. *) Bugfix: the "proxy_pass" directive did not work with the HTTPS protocol; the bug had appeared in 0.6.9. *) Bugfix: worker processes might not catch reconfiguration and log rotation signals. *) Bugfix: nginx could not be built on latest Fedora 9 Linux. Thanks to Roxis. *) Bugfix: a segmentation fault might occur in worker process on Linux, if keepalive was enabled.
