APOC Summer Release 3.2.0.4

It's summertime, but that doesn't mean we're less active building cool stuff for you to use with Neo4j.
About 3 months with almost 50 new features and fixes to APOC after our spring-release we're happy to announce two new releases for Neo4j 3.1 and 3.2.

Thank You

Of course my thanks goes to the people contributing to APOC, foremost Alberto, Angelo, Daniele, Omar, and Lorenzo from Larus Italy, who did most of the work.

Ron van Weverwijk, Brad Nussbaum, Stefan Armbruster, Valentino Maiorca, Max de Marzi, Andrew Bowman also worked on new features.

And we got fixes and improvements for code and documentation from Gabor Szarnyas, Chris Willemsen, John Bodley, Elad Wiess, and Nicholas Schiestel.

Highlights

• improvements in the Cypher export procedures
• detailed output of schema indexes and constraints
• nested (sampled) schema listing
• merge nodes and relationships with dynamic labels
• functions for working with large decimal numbers
• atomic operations on properties
• update tree structures
• updates in relational databases
• connection test of dense nodes
• XPath to access a subset of a XML document
• fuzzy matching and Levensthein distance
• virtual graph grouping

Bugfixes

• warmup had a bug that made it fail with graphs with more than 2bn nodes or relationships
• Periodic.iterate should now better report nested errors.
• Improved error messages for missing database drivers
• Dropping the exisiting schema in schema.assert is now optional
• Faster turnaround in paralellization
• apoc.convert.toMap now also works for nodes and relationships

Feedback

And of course APOC cannot improve if you don't provide your feedback, so please let us know if you like it and find it useful (best on Twitter).

If you find any issues or have ideas for improvements don't hesitate to send us issues

Of course, the best thing is to get a pull request with a bug fix or improvement.
So don't be afraid and give it a try.

APOC Release 3.2.0.3 for Neo4j 3.2.x

This is the first final release for Neo4j 3.2.0

It also contains required API changes for this new Neo4j release.

Please note that some APOC procedures now for security reasons have to be whitelisted as unrestricted, because they use internal APIs:

dbms.security.procedures.unrestricted=apoc.meta.*,apoc.node.* (or apoc.* for all).

Thanks a lot to every APOC user for the great feedback and reporting issues. Join us on neo4j.com/slack in the #apoc channel.

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

APOC Release 3.1.3.6
