Kenichi Suzuki asked Gary Illyes on Google+ what is now automated in the Panda algorithm now that this has all changed. He wrote, "Panda is now a part of the core ranking algo. Does it mean Panda will be updated automatically not manually (even if not in real-time)?"
Gary Illyes responded that parts are manual, parts are automated and it depends. But the data aspect is the same it seems. He said that Google will "roll that data out over time." Here is how he worded it:
We do continue to update the data which is used to recognize high quality sites, and we roll that data out over time. Sometimes we have to make manual updates, sometimes it's automatic, but that generally doesn't play a role in how the data is rolled out.
It seems not much has changed with Panda but what do I know?
