Jun 1, 2025June 2025 (2025-06) monthly summary for nebulastream/nebulastream. Key features delivered: added Inline GeneratorSource support in system tests to allow inline definition of GeneratorSource with explicit schema and options, and updated the system-test parser to recognize and process these inline definitions. These changes enhance test flexibility and reduce boilerplate in end-to-end scenarios.
