The new release of the Neo4j ETL tool brings several enhancements and improvements, including backend optimizations, UI changes, and bug fixes. The tool is now fully integrated with Neo4j Desktop from version 1.1.3, and it supports multiple schema parsing, additional driver support, and improved data import features. The tool also includes new features such as multi-schema support, fetch size, and CSV file writing options. Additionally, the UI has been updated to reflect these changes, and the documentation has been revised to include setup instructions for Docker containers with MS-SQL sample datasets.
