UPGRAGDE NOTICE

If your CubeFS(ChubaoFS) version is v2.3.x or before, please refer to the UPGRADE NOTICE in v2.4.0 for upgrading steps. And also please make sure that your fuse client or objectnode version is equal to or older than the servers, i.e. master, metanode and datanode. In another word, newer versioned client can not be used in a cluster with older versioned servers.

notice

This is a very important release，volume can be create as standard(3 replica) or low frequency access type(Erasure-Code), we introduce a new module BlobStore subsystem which supports erasure coding storage method(https://github.com/cubeFS/cubefs-blobstore) to support low frequency volume and reduce cost.

Due to 3.0-beta based on release-v2.4 which is lag behind master which is not easy to merge into, we let the core code is temporarily merged into one commit. If you have any questions, you can consult in the community group. All releated code and detail commit will merge into master and is expected to be released in next two months as release v3.0.0.
