Release Matrix

The number of supported Elements varies from release to release as older, unmaintained Elements are deprecated and new Elements and features are added. The SST Git devel branch may contain some Elements that are in preparation and others that have atrophied or do not currently pass their nightly regression tests. If unattended for an extended period or their utility has been superseded by a newer element, they will be removed altogether. The following matrix shows the Elements and other support directories that have been included with the latest releases. Additionally, the table shows the supported OS/compiler versions tested with each release.
