World listers will be pleased to hear that we have implemented all the recent updates to the Clements Checklist. There were many taxonomic changes, including several splits (especially amongst Asian babblers for example), a few lumps and many changes to the sequence of various passerine families.
As always, BUBO Listing will highlight any updates you need to make because of this. For details about how to do these, see how taxonomic updates are handled in BUBO Listing.
