I found this specific release that mentions that the values are no longer log2 transformed [Announcing the 24Q2 Release](https://forum.depmap.org/t/announcing-the-24q2-release/3312#:%5C~:text=To%20be%20consistent%20with%20absolute%20copy%20number%20data%2C%20the%20relative%20copy%20number%20matrix%20is%20no%20longer%20log2%20transformed) that mentions “to be consistent with absolute copy number data, the relative copy number matrix is no longer log2 transformed.” ; however, it would be helpful for confirmation.
