2024.2.0

A new minor release so shortly after the last?
We changed the behaviour of the renderer when using generated names.
Before and upto including 2024.1.0 we didn't allow aliases to be reused.
If in the original query alias x would have been legally reused, we would not have reused them with generated names, i.e. we would have usd v0 and then v1.
I think this is wrong, and we changed this behaviour, hence a new minor is due.

If you are using generated names, you can opt out of this behaviour like this:

var generatedNamesConfig = EnumSet.complementOf(EnumSet.of(Configuration.GeneratedNames.REUSE_ALIASES));
var renderer = Renderer.getRenderer(Configuration.newConfig()
	.withGeneratedNames(generatedNamesConfig)
	.build());

Apart from that, this is a drop-in replacement for 2024.1 and 2024.0.

Congratulations to @ali-ince for contributing his first feature.

And last but not least, @Andy2003 gave our AST factory and the scoping mechanism a real good test run, and we have been able to fix several bugs again.
Thank you!

🚀 Features

• Apply sorting of maps when parsing to projections, too. (#1085)
• Add call raw cypher to top level entry point (#1073)

🐛 Bug Fixes

• Don’t introduce new aliases on for each alias used. (#1084)

2022.11.0

🚀 Features

• Allow to call raw cypher from top level entry point (#1073) (#1074)

2024.1.0

This new minor release adds a third dialect: Neo4j 5.23, catering for Neo4j >= 5.23.
The initial release will rewrite sub-query CALL statements with importing WITH into sub-queries with variable scoped CALL clause.
While the former is still available in Neo4j 5.23, it will cause deprecation warnings, hence, if you want to get rid of those, change the dialect accordingly.
No need to rewrite any query on your own.

🚀 Features

• Add a Neo4j 5.23 dialect. (#1069)

🐛 Bug Fixes

• Unwrap PatternList proper if unique.

📖 Documentation

• Add an example of building a stand-alone WHERE clause.

2024.0.2

🎉 The big party release! 🎉

With this release we move the repository from github.com/neo4j-contrib to github.com/neo4j with Neo4j adding Cypher-DSL to the list of supported modules.
What we have now on our todo list is to incorporate our documentation into the official Neo4j docs, but apart from that, little will change immediate. Even our Maven coordinates will stay the same. You can however rely on the fact that Cypher-DSL is not going anywhere anytime soon.

Thanks to @stumoore for supporting this!
