## ResStock v2.6.0 (pending)

Features
- Add a new "Floor Area, Foundation (ft^2)" cost multiplier ([#870](https://github.com/NREL/resstock/pull/870))
- Add a new "Floor Area, Attic * Insulation Increase (ft^2 * Delta R-value)" cost multiplier for handling incremental costs of adding attic insulation ([#842](https://github.com/NREL/resstock/pull/842))
- Allow air leakage % reduction upgrades (e.g., 25%), and add a new "Floor Area, Conditioned * Infiltration Reduction (ft^2 * Delta ACH50)" cost multiplier for handling incremental costs of such upgrades ([#840](https://github.com/NREL/resstock/pull/840))
- For the testing project, sample equal distributions of (1) smooth and stochastic schedules (each 50%) and (2) faulted and non-faulted HVAC systems (each 50%) ([#828](https://github.com/NREL/resstock/pull/828))
