On October 19, we will enable variant C and D for newly created accounts. 40% of new accounts will get variant C, 40% will get variant D, and 20% will be in the control group that does not get the homepage or help panel. (Currently, 80% gets variant A and 20% is in the control group.) For existing accounts, nothing will change, they will continue to get variant A.
On October 26, we will remove variant A, and make variant D the default. Accounts that existed before October 19 (and newer accounts who manually enable the homepage) will get variant D.
