     ##### Removed
     ### Patches
 
+## v3.9.3
+### Minor Updates
+#### Changed
+- Set **reopt_version** in **APIMeta** and **ERPMeta** programatically based on actual REopt.jl package version in Julia environment instead of hardcoded so doesn't need to be updated by hand
+
 ## v3.9.2
 #### Added
 - Added attribute `thermal_efficiency` to the arguments of http endpoint `chp_defaults`
