# Version History
0.14.8 -
- Feature: Rallying death cry, when a native dies on a chunk past the death threshold it will attempt to summon reinforcements from nearby nests
- Tweak: Increased unit group merge distance from 16 to 28 tiles
- Tweak: Increased retreat grab radius from 15 tiles to 24 tiles
- Tweak: Decreased vengence squad cost from 50 to 45
- Improvement: On group merge recalculate the kamikaze threshold, so groups that become large have a chance to kamikaze before attacking
- Improvement: Disallow group merges when units are taking and receiving damage
- Fix: Corrected unit group frenzy trigger based on engaging a target
- Optimization: Switched to increment tick counter for processing and logic event
- Optimization: Rate limited rally cry to 3/0.75 sec
- Optimization: Rate limited retreat to 8/0.75 sec
0.14.7 -
- Feature: Counterattack waves trigger when the player is standing in a chunk with the death pheromone past the retreat threshold
- Feature: Reinforcement waves trigger when the player is standind in a chunk that contains a nest
