[Gradle Release Plugin] - creating tag:  'repository-services-1.0.10'.

This release adds the acrepo-connector-triplestore service, which indexes repository content into isolated named graphs in an external triplestore. Typically that triplestore would be configured to make a union graph available for query.

The release also adds a configuration option to acrepo-exts-image such that the default output format can be configured within Karaf (before, it was hard-coded as JPEG)
