This major release includes new features:

Persistent Client Cache allows Lustre to utilize client-local storage such as 
NVMe or NVRAM as part of the filesystem namespace.  Clients can cache the data 
of newly created or existing files in a locally-mounted cache filesystem (e.g. 
ext4) for exclusive access at local filesystem speeds, and data migrates 
transparently into the global filesystem when accessed by other clients  
(LU-10092<https://jira.whamcloud.com/browse/LU-10092>)

Multi-Rail Routing enhances multi-rail support for LNet routers, allowing auto 
discovery of routes and improved resiliency in configurations with multiple 
interfaces per node (LU-11297<https://jira.whamcloud.com/browse/LU-11297>)

Overstriping allows files to have multiple stripes of a single file on each 
OST.  This allows configurations with relatively few clients/threads or very 
large OSTs to better utilize the full storage performance 
(LU-9846<https://jira.whamcloud.com/browse/LU-9846>)

Self-Extending Layouts improves the flexibility of Progressive File Layouts 
(PFL) to better handle filesystems with imbalanced OST capacity, such as 
smaller flash OST pools combined with larger disk OST pools. Files using 
Self-Extending Layouts can write to the flash pool as much as possible, but 
will automatically change over to the disk pool if there is not enough space
(LU-10070<https://jira.whamcloud.com/browse/LU-10070>)

Fuller details can be found in the 2.13 wiki page 
<http://wiki.lustre.org/Release_2.13.0> (including the change log 
<http://wiki.lustre.org/Lustre_2.13.0_Changelog> and test 
matrix<http://wiki.lustre.org/Release_2.13.0#Test_Matrix>)

Please log any issues found in the issue tracking 
system<https://jira.whamcloud.com/>

Thanks to all those who have contributed to the creation of this release.
