Well if Steam does not list 10 July as the last change it is obvious they don’t list every one.

In fact the change of 1 July was the 1.3, wasn‘t it? Now we are on 1.3.1 and the build number has also changed at least once.

I have noticed it for months now. There are frequent changes and most are undocumented.

The changes to the game are indeed on going and they don’t feel the need to tell us about every change they make. If Steam takes more than 3 seconds to load the game you are getting something new.
