Loobinex (YourMaster) has as of 2nd of October 2019 released the next big update for the fan-made patch KeeperFX, the newest stable release is as of now 0.4.7.

It can be downloaded following this link: https://keeperklan.com/downloads.php?do=file&id=137

There are some changes which may affect speedrunning.

1: The "bug" where you could possess an imp and cave through neutral walls has been made optional. So in order to being able to break them in the classic way you need to go into KeeperFX 0.4.7 and enable it manually. (see link: https://github.com/Loobinex/keeperfx-unofficial/commit/848d84972ae3aa04bd1e0ebba4ed42ae4bfb7f3a )

2: Some minor damage changes to Meteor (Warlocks level 4 spell) and Grenade (the screaming bomb). The area damage has been reduced in both cases, Meteor sees a 25% damage reduction and Grenade a 81%. However Meteor is overall improved as it now will explode on creature impact and not only against walls. Also the direct hit damage is still the same. (https://github.com/Loobinex/keeperfx-unofficial/commit/3fd4338f95abd16e7d83e8219edb775f8cae5e04 ).

3: Dragons will now only heal when they really need to. (https://github.com/Loobinex/keeperfx-unofficial/commit/f33efa8dad62705fc3093d4ea0b7b148f8e0fc7d )

4: Lightning traps no longer deal damage to more than one unit.

5: A lot of small changes to creature AI which will improve speed of the game generally, a lot on imp priority order when digging gems etc.

6: Added frameskip for laptops. (https://github.com/Loobinex/keeperfx-unofficial/commit/0b0db7df1fd234e8d6d1f7b45ffca3abf4347776 )
