For every ATWB eBook title that is in its second or subsequent annual edition, you can view how changes to the IOC bird list have impacted on the contents of the eBook since it was first published.

In June 2019 the IOC published Version 9.2 of the bird list. Among other changes, in v 9.2 the sequence of Non-Passerine orders was radically altered. A summary of the new sequence (which is reflected in 2020 editions of ATWB Companion Guides) can be viewed here.
