APOC Release 3.2.0.2

Spring Release with many updates

See the blog post for more details

• Update to Neo4j 3.2.0-alpha07
• Documentation update, now uses generated includes for procedure overviews. Thanks @fbiville
• @sarmbruster worked on automatizing the "manual" index update
• He also added support for mixed content to apoc.load.xml,
• and provided the apoc.test.regexGroups functions for extracting parts of regular expressions.

@InverseFalcon started his first contributions last month but already added:

• apoc.coll functions: shuffle(), randomItem(), randomItems(), containsDuplicates(), duplicates(), duplicatesWithCount(), occurrences(), reverse()

• apoc.path procedures: subgraphNodes(), subgraphAll(), and spanningTree()

• apoc.date functions: convert() and add()

• apoc.algo functions: cosineSimilarity(), euclideanDistance(), euclideanSimilarity()

• He also extended the capabilities for the apoc.path.expand procedure with new operators for filtering end nodes, limits, excluding start node from filters and more.

• @tomasonjo submitted including a weight property as an improvement to the Gephi Streaming capability

Here are the things, I @jexp worked on:

• improve the performance of apoc.periodic.iterate, use iterateList:true

• Prefixing your inner statement with WITH {foo} AS foo for each return value is also no longer necessary.

• conflicting queries, you can now for instance use retries:5

• Added json-path support to APOCs load.json procedure and the different json functions.

• Some bugfixes: graphml export, TTL, setting array properties, more robust startup

• improved documentation, now there are independent versions of the docs published for the different versions.

• Bitwise operations were turned into a function

• Added apoc.text.format, .lpad, .rpad

• Added new functions for creating virtual nodes and relationships.

• Some missing procedures for updating/removing labels, properties, and relationships were also added.

• Added support for gzipped streams for load csv and load xml

The @neo4j-contrib/larus team worked on

• honour neo4j import restriction settings
• handling large ElasticSearch results and scroll support
• follow redirects for load
