Since updating to Unity 2018.4.10 I noticed all of our sprite atlases keep changing the hashes in the .spriteatlas files. This results in lots of unnecessary noise in source control. Previously we were using 2018.4.8, I'm not sure if the problem started in .9 or .10. The serialization seems to have changed (introduced storedHash), but now the hashes keep changing all the time. This is the hash I'm talking about: totalSpriteSurfaceArea: 180224 bindAsDefault: 1 storedHash: serializedVersion: 2 Hash: 7822d7233d93c2eed79db302c7a76c72 Looks like a bug to me.
