nginx 0.7.42 *) Change: now the "Invalid argument" error returned by setsockopt(TCP_NODELAY) on Solaris, is ignored. *) Change: now if a file specified in a "auth_basic_user_file" directive is absent, then the 405 error is returned instead of the 500 one. *) Feature: the "auth_basic_user_file" directive supports variables. Thanks to Kirill A. Korinskiy. *) Feature: the "listen" directive supports the "ipv6only" parameter. Thanks to Zhang Hua. *) Bugfix: in an "alias" directive with references to captures of regular expressions; the bug had appeared in 0.7.40. *) Bugfix: compatibility with Tru64 UNIX. Thanks to Dustin Marquess. *) Bugfix: nginx could not be built without PCRE library; the bug had appeared in 0.7.41.
