It’s been updated to work with contemporary versions of GregtechCE. This was essential since Gregic Additions itself was left, along with the fixes contained in GTCE supposed not upgrading was impossible. GA is accredited under the LGPLv3, and SoG is accredited under the GPLv3. This modification and relicense is permitted by the details of the LGPLv3 Section 2. This mod is an GregTech Community Edition addon, and needs it to operate.
