I am working on integrating SearchGuard with AWS managed OpenSearch, but I am not able to find any compatibility matrix to understand what all version of OpenSearch are supported by SearchGuard and also in future how it will change with new releases. I can only find it for ElasticSearch.
It is the system requirement to use Search Guard as a security plugin, I am doing analysis to either use OpenSearch or ElasticSearch. SearchGuard support is a mandate. I read that with SearchGuard FLX 1.0.0 beta, the support was added.
