    Detailed info:

    • C API *

    LizardFS 3.12 comes with liblizardfs-client library and C language API header.
    🏗 It's now possible to build programs/plugins with direct support for LizardFS operations,
    👀 no FUSE needed. For reference, see:
    src/mount/client/lizardfs_c_api.h
    src/data/liblizardfs-client-example.c

    For those building LizardFS from source, pass a -DENABLE_CLIENT_LIB=YES flag to cmake
    🏗 in order to make sure you're building client library as well.

    • 🔌 nfs-ganesha plugin *

    🔌 Our official plugin for Ganesha NFS server is included as well. This plugin enables
    a LizardFS FSAL (File System Abstraction Layer) to Ganesha, which is then used
    🔌 to access LizardFS clusters directly. Our new plugin is pNFS and NFSv4.1 friendly.

    For those building LizardFS from source, pass a -DENABLE_NFS_GANESHA=YES flag to cmake in order to make sure you're building client library as well.

    RichACL *
    👍 In order to extend POSIX access control list implementation we introduced RichACL support.
    Backward compatibility with POSIX ACLs is guaranteed. Additionally, it's possible to use NFSv4-style ACL tools (nfs4_getfacl/nfs4_setfacl) and RichACL tools (getrichacl/setrichacl) to manage more complicated access control rules.

    OSX ACL *
    💻 Setting/getting ACLs is also possible on OSX via both command line chmod/ls -e interface and desktop.

    🔒 File lock fixes *
    🔒 Global file locking mechanism is now fully fixed and passes all NFS lock tests from connectathon suite.

    AVX2 *
    Erasure code goal computing routines now take full advantage of AVX2 processor extensions.

    MinGW *
    🆓 LizardFS is now bug-free again for MinGW cross-compiling.

    Chunkserver options *
    🔧 Replication limits are now fully configurable in chunkserver config.
    ✅ Also, chunk test (a.k.a. scrubbing) has 1 millisecond precision now instead of previous 1 second, which allows users to turn on more aggressive scrubbing with simple chunkserver reload.

    Cheers,
    LizardFS Team
