The Greek Independent Authority for Public Revenue (AADE) has officially launched version 1.0.10 of the myDATA platform, now accessible in the Test Environment. This update introduces a series of enhancements designed to streamline operations for businesses and improve overall functionality within Greece's digital tax administration framework.
