v0.2.6b:

* Stability improvements:

- Fixed memory leaks causing gradual degradation over long sessions

- Fixed various death/spawn lifecycle edge cases that could cause errors

* Performance improvements:

- Significantly reduced CPU cost of slime mold networks at scale

- Fixed GPU upload path running at full cost every frame

- Particle system now scales to actual cell count instead of fixed max

* Consistency improvements:

- Fixed moving cells becoming unclickable

- Fixed strain renaming creating duplicate entries

- Fixed strain naming prompt appearing when harvesting on already-tracked cells

- Fixed first plasmodia not growing branches in some cultures

- Untracked strain variants now count towards contracts

* Balance tweaks:

- Added nutrient sliders for finer tuning of nutrient composition. Nutrient diversity slider now controls variation, 3 sliders control amino/lipid/sugar.

- Sparser default world generation

- Dish cost scales with size

- Heat retuned to be more transient in nature. Faster decay, more gradual cumulation, and higher lethality

* Visual tweaks:

- Adjust mitosis daughter size ramp and placement

- Nutrient colors reworked: reddish aminos, green/blue sugars, yellow lipids
