-## Develop - 2023-06-21
+## v0.32.4
 ### Changed
 - Consolidated PVWatts API calls to 1 call (previously 3 separate calls existed). API call occurs in `src/core/utils.jl/call_pvwatts_api()`. This function is called for PV in `src/core/production_factor.jl/get_production_factor(PV)` and for GHP in `src/core/scenario.jl`. If GHP and PV are evaluated together, the GHP PVWatts call for ambient temperature is also used to assign the pv.production_factor_series in Scenario.jl so that the PVWatts API does not get called again downstream in `get_production_factor(PV)`.  
 - In `src/core/utils.jl/call_pvwatts_api()`, updated NSRDB bounds used in PVWatts query (now includes southern New Zealand)
 - Updated PV Watts version from v6 to v8. PVWatts V8 updates the weather data to 2020 TMY data from the NREL NSRDB for locations covered by the database. (The NSRDB weather data used in PVWatts V6 is from around 2015.) See other differences at https://developer.nrel.gov/docs/solar/pvwatts/.
 - Made PV struct mutable: This allows for assigning pv.production_factor_series when calling PVWatts for GHP, to avoid a extra PVWatts calls later.
+- Changed unit test expected values due to update to PVWatts v8, which slightly changed expected PV production factors.
+- Changed **fuel_avail_gal** default to 1e9 for on-grid scenarios (same as off-grid)
 ### Fixed
 - Issue with using a leap year with a URDB rate - the URDB rate was creating energy_rate of length 8784 instead of intended 8760
+- Don't double add adjustments to urdb rates with non-standard units
+- Corrected `Generator` **installed_cost_per_kw** from 500 to 650 if **only_runs_during_grid_outage** is _true_ or 800 if _false_
 
 ## v0.32.3
