Hello everyone!

On behalf of the Charm++ development team and contributors, I'm pleased to announce the release of Charm++ 7.0.0.

The code for this release can be obtained via git by

git clone https://github.com/UIUC-PPL/charm.git
git checkout v7.0.0

Or downloaded directly from: https://github.com/UIUC-PPL/charm/releases/tag/v7.0.0

685 commits have been made since the release of version v6.10.2, some of the larger and more exciting improvements in the system include (for a full list, please see the current release notes in the CHANGES file):

A significant overhaul of the load balancing infrastructure and the
addition of TreeLB, a new, more flexible and extensible base LB,
intended to replace the previous CentralLB and HybridBaseLB designs
(load balancers using these previous designs are still
supported). Some included strategies have been rewritten to use
TreeLB, unused and extraneous strategies have been removed. Please
see https://charm.readthedocs.io/en/latest/charm++/manual.html#load-balancing
for more information.
Support for persistent intra-node GPU messages, and experimental support for
regular (nonpersistent) intra-node GPU messages. This feature allows data to be
sent to/from GPU memory without going through host memory. Please
see https://charm.readthedocs.io/en/latest/charm++/manual.html#gpu-support for
more information.
Charm++ now builds with CMake by default when using the ./build
script (requires CMake version 3.4 or higher). The old build system is
still available by using ./buildold. Please see
https://charm.readthedocs.io/en/latest/charm++/manual.html#installation-with-cmake
for more information.
