• New graph API to evaluate Gremlin scripts if JanusGraph is used embedded
• ConfiguredGraphFactory can now create different indexes for different graphs in Elasticsearch
• Add management API to remove ghost vertices
• Add possibility to remove stale graph index entries
• Improved support for Geoshapes in GraphBinary
• Remove dependency on cassandra-all
• Support TTL for CQL backend on Amazon Managed KeySpace

• Support for ElasticSearch 8
• Possibility to use dedicated ScyllaDB driver when JanusGraph is used embedded
• Possibility to explicitly remove configuration options
• Possibility to use ASCI String for vertex ids
• CQL storage layer transitioned to asynchronous calls instead of a thread pool
• Enhanced CQL storage parallelism for queries using multiple slices in the same step (multiple edge labels or multiple property keys)

• Added possibility to group CQL queries for different vertices stored on the same token ranges or same replica sets
• Improved batch-query (multiQuery) capabilities. Enhanced parent steps usage. Added batch-query optimisation to almost all execution steps (exception: ‘match’ step).
