Here's the full list of changes:
- Added the "PnP Fey creatures", "Revised Call Woodland Beings spell", "PnP Dimension Door" and "Make Death Ward protect against Vorpal Hits" components
- The components "Give Shambling Mounds their proper soundset" and "Give Mariliths their Icewind Dale soundset" have been deprecated as a stand-alone components and are now included in the new "Distinctive creature soundsets" component
- Dryads, Hamadryads, Nymphs, Sirines, Nereids and Succubi are now affected by the "Distinctive creature coloring" and "Distinctive creature soundsets" components
- Hellcats are now properly immune to all mind-affecting spells and grant 5,000 XP when killed
- The movement rate of several fiends was erroneously set too slow. Their speed now matches the given PnP rating
- Due to a typo, several mephits and fiends that are immune to fire were also erroneously made immune to Cloudkill
- Fiends of the same type will now coordinate their attacks better. When one fiend encounters an enemy, it will try to telepathically alert any nearby fiends of its type to the enemy's presence. The alerted fiends will then attempt to teleport to its location
- Oozes, constructs, elementals, skeletal undead and incorporeal creatures are now immune to the Balors' vorpal hits
- The intense flames which engulf a Balor's body will now burn through webs and any entangling vegetation. They will also repel insects and bat swarms
- Improved the targeting routine of Imps and Quasits. Also, Quasits now use a Blast of Fear (30' radius) instead of the regular (cone shaped) Fear spell, as per PnP
- Ka'rashur and Tahazzar should now go hostile a bit more reliably
- Further optimized Mariliths' Cloudkill use
- Summoned Balors can now finish off Trolls that have been knocked down by approaching them and triggering the Body Flames ability
- The Pit Fiend summoned through the portal in the maze below Spellhold can no longer be attacked before the gating animation is complete
- Restored the Pyrotechnics spell-like ability to Balors, Mariliths, Abishai, Cornugons and Pit Fiends
