Neo4j 3.4.0-alpha07 已发布，Neo4j 是世界领先的高性能图数据库，具备成熟和健壮的数据库的所有特性，如友好的查询语言和事务的 ACID 原则。
Kernel
Much reduced memory usage of collision values in importer
Rename setting dbms.logs.timezone to dbms.db.timezone
Make dbms.tx_log.rotation.* settings dynamic
Add "Page cache usage" metric
Cypher
Fixes bug where optional match or pattern comprehension with relationship created earlier in the same query did produce too few results.
Bugfix so that the cost planner can now plan the following
REMOVE CASE WHEN ... THEN a ELSE b END.prop
Queries such as match (n),(m) return m as m2, n as m order by m
were rewritten incorrectly to sort by the wrong column m as m2. Now, the result is correctly ordered by n as m.
Fixes planner bug with join hints on optional matches
Security
Remove deprecation annotation for legacy ssl settings
Tools
Added a neo4j-admin memrec command, which can print recommendations for the Neo4j heap and pagecache memory settings.
Misc
Fix a bug where Causal Cluster store-copy or online backup would occasionally get stuck in an infinite loop during recovery of the temporary store. Also makes store copy faster in HA, CC and online backup.
remove initial heapsize settings for neo4j scripts
