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 #10723

• Rename setting dbms.logs.timezone to dbms.db.timezone #10782

• Make dbms.tx_log.rotation.* settings dynamic #10819

• Add "Page cache usage" metric #10861

Cypher

• Fixes bug where optional match or pattern comprehension with relationship created earlier in the same query did produce too few results. #10842

• Bugfix so that the cost planner can now plan the following: #10863

  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 #10867

  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. #10895

Security

• Remove deprecation annotation for legacy ssl settings #10762

Tools

• Added a neo4j-admin memrec command, which can print recommendations for the Neo4j heap and pagecache memory settings. #10821

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. #10843

• remove initial heapsize settings for neo4j scripts #10851
