[Si, Min]

We are pleased to announce the alpha release of OSHMPI-2.1 (version 2.1a1) and the release candidate of OSHMPI-2.0 (version 2.0rc1). OSHMPI is a portable OpenSHMEM implementation on top of MPI. 

Release tarballs are available at:
https://pmodels.github.io/oshmpi-www/downloads.html

### A list of new features in version 2.1a1:

- Support a prototype of memory space with CUDA memory kind.

- Enable MPI dynamic window based optimization.

- Add configure option to force inline performance critical routines.


### A list of new features in version 2.0rc1:

- Do not inline performance noncritical paths.

- Enable operation tracking to avoid unnecessary network flush.

- Enable datatype cache to reduce MPI derived datatype creation overhead at strided operations.

- Disable internal assertion when --enable-fast configure option is set.

- Update openpa git repository URL.

- Bug fixes:
  + Unsupported MPI datatype with complexd reduce calls.
  + Compile openpa only when multithread safety is set.

Details of each feature can be found in CHANGES (https://github.com/pmodels/oshmpi/blob/main/CHANGES) and README (https://github.com/pmodels/oshmpi/blob/main/README.md).
