• Support for installing and trying out Apache SeaTunnel(Incubating) via Docker containers.
• SQL component supports SET statements and configuration variables.
• Config module refactoring to facilitate understanding for the contributors while ensuring code compliance (License) of the project.
• Project structure realigned to fit the new Roadmap.
• CI&CD support, code quality automation control (more plans will be carried out to support CI&CD development).
