New
===

*EM_EP_CELLMODEL_STEP: New keyword

*EM_EP_EIKONAL: Added Card 3.

*EM_EP_ECG: Added last sentence to the purpose about which solvers are supported (only new one is EMSOL = 16).

*EM_MAT_001: Added to the MTYPE = 2 description a capability for Electro-Physiology.

*ICFD_BOUNDARY_PRESCRIBED_WATERVAPOR: New keyword.

*ICFD_CONTROL_RANS: New keyword.

*ICFD_CONTROL_LOAD: Added last sentence to the purpose. Added DIR and VAL. Added remarks.

*ICFD_CONTROL_TURBULENCE: Removed all Card 2s except Card 2b. Renamed Card 2b as Card 2. Removed TYPLUS from Card 1. Changed SUBM = 2 for the TMOD = 2. Removed WLAW = 2, 4, and 5. Added WLAW = 8. Updated all the remarks, except Remarks 7 and 8. 

*ICFD_INITIAL_WATERVAPOR: New keyword.

*ICFD_MODEL_SPECIES_TRANSPORT: Added HVAC to Card 1. Added Card 4. Added Remark 1.

Error Fixes and Clarifications
==============================

*DUALCESE_INITIAL_CHEMISTRY: Fixed description of CHEMID which should have linked to *CHEMISTRY_CONTROL_FULL

*DUALCESE_INITIAL_CHEMISTRY_REGION: Fixed description of CHEMID which should have linked to *CHEMISTRY_CONTROL_FULL

*DUALCESE_INITIAL_CHEMISTRY_SET: Fixed description of CHEMID which should have linked to *CHEMISTRY_CONTROL_FULL

*EM_CONTROL_EP: Description of IONSOLVR = 2 referred to incorrect values of EPSOL for the eikonal solvers. The eikonal solvers were missing from EPSOL. 

*EM_DATABASE_NODOUT: Changed EQ.1 to GE.1 for OUTLV and updated the description. Updated Remark 1 to go with this fix.

*EM_EP_EIKONAL: Fixed the purpose of this keyword to refer to both reaction eikonal solvers. EIKPST = 0 description was missing.

*ICFD_BOUNDARY_PRESCRIBED_TURBULENCE: Added to the purpose. Fixed the equations in the remarks.
