v4.0.0

New baselines

The minimum required versions are Java 17 and Neo4j 5.x.

Removal of Auto Index Manager

The Auto Index Manager that was responsible for creating indexes and constraints out-of-the-box
got removed from the Neo4j-OGM.
Please use tools like Neo4j-Migrations (has support for Neo4j-OGM annotations out of the box) or Liquibase with the Neo4j-Plugin enabled (needs manual scripts for OGM entities) to control your schema. They offer a broader feature set than just focus on indexes and constraints.
Although the functionality was removed, the annotations are still available. Those will stay in place to avoid refactoring your codebase and support Neo4j-Migrations' annotation processor to make the transition easier.

Removal of HTTP and embedded transport support

Since Neo4j 4.x Neo4j-OGM did not offer embedded transport but the module was still available for users connecting to a 3.5.x instance.
Because the baseline of the official supported database was raised to Neo4j 5.x with this release, the embedded option got deprecated.
The HTTP transport mode was removed because it was rarely used and could not compete with the broad feature set that Bolt allows you to have.
