SF 0.561 Internal Test Version

Update：

1, Because the old encryption tool make SF start so slow, so we change a new tool to protect SF. but it may lead many problems such as whether it is stable or laggy or something else. so this version should be an internal version for test group and test 1 or 2 days to see whether and how much is the bad affect. and i hope this tool's strength not too weak. it is the only and biggest update in this version.
