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.
