FastCFS v3.7.1发布，支持用户附加组，完全符合POSIX标准，解决了在FastCFS的fuse client上跑NFS（套娃模式）可能碰到的访问权限问题。
v3.7.1改进和修复的问题如下：
[fdir] service_stat add fields: version, auth_enabled and storage_engine
[fdir] list dentry support special dentries . and ..
[fdir] call get_path_block_size only when read_direct_io is true
[fdir] dentry_remove bugfixed: correct posix ACL check
[fstore] service_stat add version field and support options: -G and all
[libserverframe] check socket connected on unexpected stage
[libserverframe] get_leader_connection: failover on multi ip addresses
[libserverframe] change log level to debug for hash entry reclaim
[libfastcommon] parse_bytes support space charactors (before and after the unit)
[libfastcommon] fc_fallocate fail back to ftruncate under Linux
FastCFS 针对intel和arm架构分别提供了 rpm 和 deb 包，欢迎大家安装和体验。
