Note: Scythebill 15.3.1 was released on July 19th, and fixes how the IOC White-spotted and Streak-headed Mannikins are handled.
IOC 11.2 was just released, and it's a big one! By my accounting, there's 82 different splits (and, yes, 1 lump), including the absolutely mega 12-way split of Rufous Antpitta, as well as a 3-way split of Green Bee-eater, the Mew Gull split into Common and Short-billed Gulls, and a whole lot more - especially for those of you who've birded southeast Asia extensively.
After updating, head to Special reports, then Splits and lumps, and see just what you gained and lost. Just 14 new for me:
As always, checklists have been updated. Ranges of some of the migratory species (Atlas Wheatear, Siberian House Martin) are a bit speculative - let me know if you spot anything off.
It's been just a week or so since the last version of Scythebill was released (15.2.4), so there's not a lot new beyond that. (Though definitely check out the 15.2 blog post if you skipped that release for everything that happened there.)
One change may help users that have added their own custom checklists - Scythebill can now show combined custom checklists, not just combined built-in checklists. Just control-click (or command-click on MacOS) any two locations in "Browse by location" and Scythebill will generate an on-the-fly combined checklist.
