* Version 1.3
This release introduces some useful features and optimizations
in libpmemobj. Most of them are experimental and controlled by
the new pmemobj_ctl APIs. For details, please check the feature
requests identified by the issue numbers listed next to the items below.
Other important changes are related to performance tuning and
stabilization of librpmem library, which is used by libpmemobj to get
remote access to persistent memory and to provide basic data replication
over RDMA. The librpmem is still considered experimental.
NVML for Windows is feature complete (except for libvmmalloc).
This release includes the support for Unicode, long paths and
the NVML installer.
New features:
- common: add support for concatenated DAX Devices
