The next update to PBS will bring us to version 19-3. The information below is to bring you up to date on the changes that this update will feature.
With the update to PBS is also a change to new servers. This will give greater stability during bidding vs the old servers. This move will also bring about a change to the sign in process which will use a Single Sign On (SSO) process. SSO will redirect you to the AC Portal for signing in only. After you sign in you are brought back to PBS.
Below is an in-depth bulletin that deals with this subject:
