3.3.8

Kernel

  • Consistency-checker PropertyReader detects circular property chains
  • Remove property key tokens limit from BatchInserterImpl.

Causal Clustering

  • Check recovery status of store when bootstrapping cluster
  •  Make sure we stream transactions as far as is required or fail.

3.3.7

Kernel

  • : Fixing bug that could cause checkpoint to hang forever if recovery cleanup job fails with OutOfMemoryError.
  • Reuse threads between cleanup jobs during recovery. This fixes an issue where user would see java.lang.OutOfMemoryError: unable to create new native thread caused by Neo violating the number of allowed tasks per process, set by system.
  • Upgrade the Bouncy Castle dependency to version 1.60.

Cypher

  • Fix a bug where predicates inside pattern comprehensions could end up not being correctly planned which could lead to incorrect results

  • Take Query Parameters over default arguments. If you don't provide actual arguments, but query parameters instead (like in CALL org.neo4j.aNodeWithLabel params = Map("label" -> "Cat") ) this will from now on use the provided parameters and override any default arguments. It was preferring default arguments before, if they existed.

  • Reverts the restriction on passing unknown keys to the point function. Behaviour is now as it was before, allowing complex maps. Users need to take note of the fact that this means a map like {x:1,y:2,z:3} will create a 2D point in Neo4j 3.1-3.3, but a 3D point in Neo4j 3.4 and later.

  • Pattern comprehensions in other expressions were not planned correctly. Example:

    size([ (a)-->(b:B) WHERE (b)-->(:C) b.foo ]). This is now fixed.

  • Fixed issues with WRITE procedures interacting badly with their enclosing Cypher read queries by allowing authors to add an eager attribute to the @Procedure annotation.

  • Fixes https://github.com/neo4j/neo4j/issues/12017 so when solving an OR predicate, other predicates are only considered solved if they were solved in both underlying operators.

3.3.6

Kernel

  • Improved timer service
  • Release the storecopy mutex after the store copy

3.3.1

Kernel

  • Fix a NullPointerException bug that could disrupt transactions if a transaction event handler was registered in between beforeCommit and afterCommit
  • Fix a bug that prevented page cache metrics from the Causal Cluster replication from being reported
  • Fix bugs in neo4j-shell CALL and trav commands

  • Keeps fewer transactions in memory during recovery
  • Fix an integer overflow bug that prevented allocation of 512 GiB or more for the page cache.

Cypher

  • Properly handle filtering with empty properties map

  • Fixes #9685 so nested function calls in ELSE inside shorthand CASE works correctly

  • Fixes #3870 so that null values in a parameter map is ignored on CREATE.

  • Fixes #10021 so that we can concatenate and reverse lists of mixed types

  • Fixed bug in shortestPath with predicate depending on multiple patterns

  • Fixes #6568 so that the error message for missing a colon in the relationship type becomes more helpful.

  • Fixes bug in pattern matching around pruning var expand

  • Fixes #9492, so that PruningVarExpand after optional match will handle incoming null nodes

  • Fixes #9492, so that PruningVarExpand after optional match will handle incoming null nodes

  • Fixes #10353 so that calling exists or IS NOT null on a property of a null node evaluates to null rather than throwing an exception

  • Fixes problem around equality and lists with single values

  • Improved error message for invalid regex syntax.

  • Fixes equality for lists in accordance with OpenCypher.

    Before this change, [1,2,3] = [1,2,null] returned false. Now, this comparison will return null which makes equality more consistent in it's behaviour.

  • Fixes #10387, ArrayIndexOutOfBoundsException for index scans in the slotted runtime for some queries.

  • Report statistics for changing node key constraints

  • Add renaming of ambiguous variable name in property to semantic table

    Fixes #10444

  • Fixes issue with medium and large databases that might change relatively slowly from never having their Cypher queries replanned. This has been achieved by having the database statistics divergence threshold set by cypher.statistics_divergence_threshold shrink over time, by default from 75% to 10% over 7 hours. The decay is modelled using an inverse function that tends toward zero over many days, and so ultimately all queries will get replanned if even small changes occur.

  • Only open an InputStream in LoadCSV when needed

Causal Clustering

  • Implement a pre-election stage in Raft protocol

    This should reduce the incidence of unnecessary elections caused by a disruptive follower, for example rejoining the cluster after a network partition. This is a breaking change and must be explicitly enabled with causal_clustering.enable_pre_voting=true.

  • New cache for in-flight Raft entries

  • Add unified causal clustering REST endpoint

  • Upgrade to netty 4.1.17.Final

  • Raft heartbeat messages refresh election timeouts on receive rather than on process.

    This addresses unnecessary elections caused by the raft message processing being delayed and failing to reset election timeouts in a timely manner.

    Since java exits with code 143 when stopped the service should treat this as a graceful exit.

  • Fixed broken service installation for paths with spaces on Windows
