2021.3.4

2021.3.4 is a pure bug fix release.

🐛 Bug Fixes

• GH-252 - Use a namespace for the message bundle.

2021.4.1

🚀 Features

GH-230 - Add a way for a programmatic sort definition on expressions.

🧹 Housekeeping

• Tons of dependency upgrades in test scope
• Upgrade to Neo4j-Java-Driver 4.4.1. (a provided dependency)
• The parser module now uses the Neo4j 4.3.6 parser

2021.4.0

2021.4.0 updates the optional dependency to Querydsl to 5.0.0. While this is API
not a breaking change, it can be when the Cypher-DSL is run together with Querydsl on the Java Module path. Querydsl
maintainer finally introduced automatic module names for all their module on which we can no reliable depend. As that
module name is however different from the generated one, it will be a breaking change on the module path. Therefore
we bump our version, too.

🧹 Housekeeping

• Upgrade Querydsl to 5.0.0

2021.3.3

2021.3.3 is a pure housekeeping release, however a release we are proud of. We do analyze this project now with SonarQube
vie Sonarcloud and are happy to announce that we have a quadruple A rating:

In addition, we finally invited Dependabot taking care of at least creating the PRs.

🧹 Housekeeping

• Fix reliability and security issues
• Fix a minor amounts of remaining code smells
• Bump several dependencies (only test and build related)

2021.2.4

2021.2.4 is a pure bug fix release.

🐛 Bug Fixes

• GH-203 - Introduce a scope for the PatternComprehension.

2021.3.2

🚀 Features

• Add support for QueryDSL's equalsIgnoreCase operator
• GH-204 - Provide access to identifiable expressions (See Retrieving identifiable expressions)

🧹 Housekeeping

• Fix several (compile) warnings
• Fix several spelling errors in api docs
• Upgrade Spring Data Neo4j to 6.1.5 (In module org.neo4j.cypherdsl.codegen.sdn6)
• Upgrade Neo4j Cypher Parser to 4.3.4 (In module neo4j-cypher-dsl-parser).
• Verify examples on JDK 17

2021.3.1

2021.3.1 is a pure bug fix release. API Guardian cannot be an optional dependency, otherwise compiling programs with -Werror
will fail, as the @API-annotation has runtime and not class retention.

🐛 Bug Fixes

• GH-203 - Introduce a scope for the PatternComprehension.
• Revert "GH-202 - Make API Guardian an optional / provided dependency."
• Support empty BooleanBuilder in QueryDSL adapter.

2021.3.0

2021.3 builds straight upon 2021.2.3, with few additions to the existing API, that didn’t quite fit with a patch release, but belong conceptually into this release, which brings a completely new module: The neo4j-cypher-dsl-parser.

🚀 New module: The Cypher-DSL-Parser

What’s behind that name? A Cypher-Parser build on the official Neo4j 4.3 parser frontend and creating a Cypher-DSL-AST or single expressions usable in the context of the Cypher-DSL.

The module lives under the following coordinates org.neo4j:neo4j-cypher-dsl-parser and requires JDK 11+ (the same version like Neo4j does). We created a couple of examples, but we are sure you will have tons of more ideas and therefore a looking for your feedback, regardless if we missed out something in the API, bugs or just remarks.

Here’s a sneak preview. It shows you can add a user supplied Cypher fragment to something you are building using the DSL.

var userProvidedCypher
    = "MATCH (this)-[:LINK]-(o:Other) RETURN o as result";
var userStatement = CypherParser.parse(userProvidedCypher);

var node = Cypher.node("Node").named("node");
var result = Cypher.name("result");
var cypher = Cypher
    .match(node)
    .call(
        userStatement,
        node.as("this")
    )
    .returning(result.project("foo", "bar"))
    .build()
    .getCypher();

For this release a big thank you goes out to the Cypher-operations team at Neo4j, listening to our requests and ideas!
