This page does not list opDispatch or the change to operator overloading opBinary... It should probably also mention attributes: @property, @system... It also doesn't mention the addition of std.concurrency, std.json, and the move to std.memory using a GC struct. Coming is std.gregorian The deprecation of std.regexp for std.regex I'm sure I'm missing stuff.
I think we should just remove that page, features and modules are added often enough that it becomes a drag having to document changes as compared to D1.
I'm going to label this as won't fix, feel free to change it back if you disagree. No one outside of companies like Sociomantic are using D1 anymore, and they are well aware of the benefits of D2. We don't need to keep this up to date for their sake. D1 vs D2 is no longer the Python 2 vs Python 3 of D.
