FYI, Interesting discussion thread started in github... https://github.com/apache/incubator-openwhisk/issues/2473
When installing the catalog, the HEAD of the master branch is currently always pulled. While we take care to only merge stable changes, mistakes can happen and bugs could be introduced. Instead of always pulling from HEAD, we could pin this value to a specific tag or commit hash, which requires a separate update (presumably after integration testing is done) to pull in new versions. https://github.com/apache/incubator-openwhisk/blob/master/ansible/group_vars/all#L257 Kind regards, Matt
