I am looking for the changelog.

Who did upgrade already? All went well?

There is a new "Image Locations" section for setting where your header images, favicon, and logo are stored so theme upgrades (after this and if configured properly) will not lose the images as in the past.

There is also a new Center Column section where you can add new widget areas above and below the center column (EG the loop).

I've done my atahualpa upgrade.
the strange case occurs in the head of the ata-settings
There is the correct version 3.7.12, and the message that ata 3.7.11 is released.
see Attachment

It will take a day ot two for that message to catch up with the wordpress release.

thanks juggledad, i''l wait for that to happen.

The indicator is now showing 3.7.12 as the latest release.
