As you see, this is a very long list of tasks. So let me highlight a few =
important things:

1. Java 21+ is required

2. With the help of Claude Code polished the Modeler. While it generally =
looks the same as before, active users will notice that a number of =
small annoying UI/UX issues were fixed. BTW, if your own pet Modeler bug =
is not yet addressed, please speak up.

3. Native support for AI-assisted development. This includes an MCP =
server bundled with the Modeler that allows your favorite agent to (A) =
open your project in the Modeler, (B) run DB Import, (C) run cgen. MCP =
works with any agent of course. Additionally, there is a plugin for =
Claude Code with a number of typical "skills". See the docs for details: =
https://cayenne.apache.org/docs/5.0/cayenne-guide/agentic-coding/  And =
we'd love feedback on this too.
