 * MDC has `proxy_get`, which make block objects propagate to site clusters when they are requested. Now, multibag configuration with MDC supports `proxy_get`. [[PR 1171](https://github.com/basho/riak_cs/pull/1171) and [PR 25](https://github.com/basho/riak_cs_multibag/pull/25)]
-* Configuration options to replicate blocks in realtime replication (`replicate_cs_blocks_realtime`) and to replicate block tombstones in realtime replication (`replicate_cs_block_tombstone`) are now available. `replicate_cs_blocks_realtime` relieves the load in fullsync replication (there will be a longer realtime queue in realtime replication and risk of dropping manifests or other important keys), and it is set to `false` by default. `replicate_cs_block_tombstone` causes source block deletes caused by garbage collection to be replicated to the sink cluster. This option is set to `true` by default. Both configuration options are set in the advanced.config of the Riak node, rather than in the Riak CS configuration.
