- Compatibility fixes for Matplotlib 3.9
- Fix bug that could prevent parameter sweeps from running
- Fix bug when redrawing the control panel in a Jupyter notebook
- Improved reliability of `params.remove()`
- Simplified parameter ID tuples and deprecated the old pattern, which had been redundant since 1.4. Per-good and per-breed parameter values can now be retrieved with `(paramName, itemName)` instead of `(paramName, itemType, itemName, primitive)`.
- Remove `square`, `x`, and `y` arguments from `model.spatial()`, which were deprecated in Helipad 1.5 and replaced with a `dim` argument
