nginx 0.7.27
*) Feature: the "try_files" directive.
*) Feature: variables support in the "fastcgi_pass" directive.
*) Feature: now the $geo variable may get an address from a
variable.
Thanks to Andrei Nigmatulin.
*) Feature: now a location's modifier may be used without space before
name.
*) Feature: the $upstream_response_length variable.
*) Bugfix: now a "add_header" directive does not add an empty value.
*) Bugfix: if zero length static file was requested, then nginx just
closed connection; the bug had appeared in 0.7.25.
*) Bugfix: a MOVE method could not move file in non-existent directory.
*) Bugfix: a segmentation fault occurred in worker process, if no one
named location was defined in server, but some one was used in an
error_page directive.
Thanks to Sergey Bochenkov.
