Subject: UPC++ 2020.3.2 Release Announcement

The Pagoda project at Lawrence Berkeley National Laboratory is proud to announce the release of UPC++ 2020.3.2, now available from upcxx.lbl.gov. This is a bugfix release that corrects several defects, as detailed in the ChangeLog. Highlights are listed below.

The 2020.3.0 releases of the UPC++ Specification and UPC++ Programmer’s Guide are still the current versions. The UPC++ Training site includes videos of past tutorials and hands-on exercises, and is the best place to get started learning the library.

Please use the issue tracker to report any problems or make feature requests.  Alternatively, if you have private feedback or questions not suited to a public venue, you can email: pag...@lbl.gov.  We welcome all feedback.
