2023.9.0

2023.9 contains several new features: It brings support for parsing and rendering Quantified Path Patterns (QPP), shifts to a single, easy to find main entry point to the DSL via just Cypher and makes the static code generator a bit more powerful.

While QPP are a powerful feature (have a look at "Getting From Denmark Hill to Gatwick Airport With Quantified Path Patterns" to see what you can do with them), I find them a bit hard to read, with all the parentheses and I did not expect them to really fit in well with our builder. However, it turned out that the elements we need to provide in our own AST to render what we parsed do work well: If you decide to build QPP with Cypher-DSL, you can now quantify relationship patterns as a whole or only the relationship, making up already for many uses cases.

The single entry point to our API makes the whole system a lot more discoverable.
@lukaseder did create a ticket for that in the beginning of 2023 and if someone knows the importance of that, he is that someone as the creator of jOOQ.
Thank you, Lukas and of course earlier this week, @Andy2003 for actually doing the work of adding all those methods to Cypher.

If you don't care about deprecation warnings, 2023.9.0 will be a drop-in replacement.
The existing entry points won't go away until the next major release, in which they will be made package private.
Until then, they are deprecated.

It my sound like a broken record by now, but again: Thank you, @zakjan and @ikwattro for your input on QPP, now we are waiting for your bug-reports.
