UPDATE: A new letter just got sent out today "explaining" the changes. Keep your eyes peeled on avoidjw.org for a copy of the official letter. In the meantime, here's what they say:

TO ALL BODIES OF ELDERS
Re: Personal Addresses and Adjustments to Coordinator of the Body of Elders or Secretary
Dear Brothers:
We are pleased to inform you of two features that are now available on jw.org.
Managing Personal Addresses: Most jw.org users who have been added to the jw.org congregation domain can now manage their personal address information using the “My User Profile” link under the “My Preferences” section of the “Administration” tab. Each user’s profile includes a “My Personal Addresses” section with a link that allows him to enter or update his addresses. For more information on how to use this feature, click on “Help.” Please note that addresses for some jw.org users are maintained by the branch office and cannot be edited online.
Informing the Service Department of a Change in Coordinator of the Body of Elders or Secretary: An online version of the Coordinator of the Body of Elders/Secretary Change of Address (S-29) form can now be accessed by elders who have been assigned the “Enter Member Information” role. This feature can be found using the “Elders and Servants” link under the “Members” section of the “Congregation” tab. When this feature is used, it is not necessary to send a printed or PDF version of the S-29 form to the Service Department. For more information on how to use this feature, click on “Help.”
We trust that these new features will be of benefit to you. We send our warm Christian love and best wishes.
Your brothers,
