From CHANGELOG.md

Added

• Added optional LUN argument to ConfigInit to allow external models to pass LUN of existing log file
• Added two log LUN variables (stdLogLUN and hcoLogLUN) to HcoState%Config for stdout and HEMCO log and initialize both in ConfigInit to stdout or optional LUN (if passed)
• Added output argument LUN to HCO_LOGFILE_OPEN to update HcoState%Config%hcoLogLun to LUN of new log (if using)
• Added optional LUN argument to HCO_MSG, HCO_WARNING, and HCO_ERROR to specify log to print to
• Added special log handling for CESM to ignore LogFile entry in HEMCO_Config.rc (will get passed CAM log LUN to use instead)

Changed

• Changed interfaces HCO_MSG, HCO_WARNING, and HCO_ERROR to each be a single subroutine that does not use HcoState%Config%Err
• Changed HCO_MSG, HCO_WARNING, and HCO_ERROR to be independent of verbose and cores
• Updated calls to HCO_MSG to send output to HcoState%Config%hcoLogLUN
• Updated calls to HCO_WARNING to print to stdout unless related to units
• Replaced usage of HCO_IsVerb with HcoState_Config%doVerbose
• Changed documentation in HCO_Error_Mod.F90 to summarize error and log handling in HEMCO
• Updated ReadTheDocs "Understand what error messages mean" supplemental guide

Fixed

• Fixed excessive prints when using MPI
• Fixed F77 formating in hcox_dustdead_mod.F

Removed

• Removed warnings count in HcoState%Config%Err
• Removed RC argument in HCO_WARNING
• Deleted subroutine HCO_IsVerb
• Remove print of HcoDiagn%MassScal since never set in the model
• Added ReadTheDocs documentation for the HEMCO LogFile setting
