The to version 4.90 was particularly significant because it coincided with a strong emphasis on the IEC 61850 system configurator. This version was designed to simplify the engineering process for substation automation, offering manufacturer-neutral support for the IEC 61850 standard, which is crucial for interoperability between different vendors' devices in modern smart grids. It also improved the handling of SCL (Substation Configuration Language) files. Notably, the IEC 61850 System Configurator V5.30 from Siemens is not compatible with DIGSI versions older than 4.90, making this update a baseline requirement for users working with modern IEC 61850 projects.
Better stability on modern operating systems compared to versions 4.8x.
