nginx 0.8.36
*) Bugfix: the ngx_http_dav_module handled incorrectly the DELETE,
COPY, and MOVE methods for symlinks.
*) Bugfix: values of the $query_string, $arg_..., etc. variables cached
in main request were used by the SSI module in subrequests.
*) Bugfix: a variable value was repeatedly encoded after each an "echo"
SSI-command output; the bug had appeared in 0.6.14.
*) Bugfix: a worker process hung if a FIFO file was requested.
Thanks to Vicente Aguilar and Maxim Dounin.
*) Bugfix: OpenSSL-1.0.0 compatibility on 64-bit Linux.
Thanks to Maxim Dounin.
*) Bugfix: nginx could not be built --without-http-cache; the bug had
appeared in 0.8.35.
