[Update #2]: Total War: Warhammer 3's Update 2.3 has added new landmarks, tied AI behavior to difficulty, and rebalanced most factions.
[Update]: Total War: Warhammer 3's Update 2.2 will beef up the AI and reduce the number of settlement battles.
As a part of the absurdly gigantic Update 2.0, Total War: Warhammer 3 has added the Immortal Empires combined campaign map, spruced up many of the long-forgotten Total War: Warhammer 2 lords, finally added the missing blood & gore effects, and even reworked the Warriors of Chaos faction from the ground up. Add to that the first-post launch DLC, a variety of quality-of-life improvements and balance changes, and you've got yourself the biggest update the Total War: Warhammer series has ever seen.
Naturally, as you would imagine given the sheer scope of the changes, Update 2.0 has also brought with it a fair few bugs, balance issues and general nuisances. So in order to sort these problems out, as well as to pave the way for a much bigger patch in October, Creative Assembly has now unleashed Update 2.1.
The highlight of Update 2.1 is not a simple bug fix, however, but rather the much-anticipated arrival of the Warhammer 3 Assembly Kit! This handy little tool provides the modding community with the ability to create battle maps, change starting positions, edit the game's database, generate their own pack files, and the list goes on for a while.
To put it quite bluntly, the exact details are irrelevant. What is relevant is that this will lead to a whole assortment of new and highly ambitious mods, which given the already excellent modding community that surrounds the series, is sure to result in something spectacular! All of this will take a little bit of time to bear fruit, so for the time being I'd recommend against getting too excited.
Once the next big update arrives, most likely in October, I'll make sure to let you know. Until then you can read the full list of changes for Update 2.1, as well as Creative Assembly's commentary, over at the Total War website.
Enjoy, and I'll leave you with the brief video summary:
