- `SolarAbsorptance` and `Emittance` now only required for *exterior* walls & rim joists (i.e., ExteriorAdjacentTo=outside).
- `Window/PerformanceClass` no longer required (defaults to "residential").
- Allows above-grade basements/crawlspaces defined solely with Wall (not FoundationWall) elements.
- Adds ZERH Multifamily v2.
- Updates to ZERH Single Family v2 windows SHGC in climate zone 4 through 8.
- Allow JSON output files instead of CSV via a new `--output-format JSON` commandline argument.
