### Bug Fixes
* Fixed a major bug in which batched MultiGet could return old values for keys deleted by DeleteRange when memtable Bloom filter is enabled (memtable_prefix_bloom_size_ratio > 0). (The fix includes a substantial MultiGet performance improvement in the unusual case of both memtable_whole_key_filtering and prefix_extractor.)

// Do not use these. We made the mistake of declaring macros starting with
// double underscore. Now we have to live with our choice. We'll deprecate these
