nginx 1.0.6 *) Feature: cache loader run time decrease. *) Feature: loading time decrease of configuration with large number of HTTPS sites. *) Feature: now nginx supports ECDHE key exchange ciphers. Thanks to Adrian Kotelba. *) Feature: the "lingering_close" directive. *) Feature: now shared zones and caches use POSIX semaphores on Solaris. Thanks to Den Ivanov. *) Bugfix: nginx could not be built on Linux 3.0. *) Bugfix: a segmentation fault might occur in a worker process if "fastcgi/scgi/uwsgi_param" directives were used with values starting with "HTTP_"; the bug had appeared in 0.8.40. *) Bugfix: in closing connection for pipelined requests. *) Bugfix: nginx did not disable gzipping if client sent "gzip;q=0" in "Accept-Encoding" request header line. *) Bugfix: in timeout in unbuffered proxied mode. *) Bugfix: memory leaks when a "proxy_pass" directive contains variables and proxies to an HTTPS backend. *) Bugfix: in parameter validaiton of a "proxy_pass" directive with variables.
