- The Radionuclide sensitivity coefficient 1.8.6 conversion logic was updated to identify the class-based sensitivity coefficients, and convert them to the 2.1 class-based sensitivity coefficient format.
Version 1.2.3 - Released 5/11/2010:
- The 1.8.6 conversion logic was updated to resolve an issue converting sensitivity coefficients into 2.1. Additionally importing a MELCOR model that includes the sensitivity coefficient array will flag all of the packages that have active sensitivity coefficients as included in the MELCOR file.

Version 1.1.3 - Released 11/2/09:
- The 1.8.6 conversion logic was modified to better determine which components are included in a 1.8.6 MELCOR file. The previous logic was based on whether the input for the component changed from the MELGEN input. This was changed to ensure that all components included in the 1.8.6 MELCOR file will be flagged as MELCOR data, even if the properties are not changed by the MELCOR file.
- The Plug-in file read and write routines have been modified to greatly improve performance, and to significantly reduce the size of the resulting MED files.
- When converting a 1.8.6 model to 2.1 the Release Path cross reference data will correctly resolve to refer to the Flow Path in the 2.1 model. This resolves issues importing the MACCS flow variables from 1.8.6 models. Additionally the flow variable has been modified to support the total Aerosol (AER) and total radioactive release (TOT) options for the MACCS release mass variable.
- The Core component has been modified to support the reflector equivalent diameters card and the reflector geometry cards. These properties can be edited through the Cell Geometry editor on the Core Component. Additionally an issue was resolved with the Cell Initial Mass editor which prevented specifying the initial reflector in each cell.
- An issue has been resolved with importing parallel files that contain control volumes, flow paths, or fan coolers which could result in the model editor never returning from the import correctly, and prevent the right-click menu on navigator nodes from opening.
- The 1.8.6 conversion logic for control volumes has been modified to handle the case where the fog option flag on water sources is entered as a default.
- Control functions were modified to report an error message when an argument fails to resolve during 1.8.6 conversion.
Version 1.1.2 - Released 10/8/09:
- The 1.8.6 input conversion logic has been modified to initialize the vapor state property of control volumes based on the initial conditions defined in the volume.
- The control volume component was modified to ensure that the initial temperature fields are enabled when a subcooled pool or superheated vapor region are present inside the volume.
- The radionuclide 1.8.6 conversion logic was modified resolve an issue which caused the pool scrubbing flow direction flag to be reversed during the conversion process.
- The post-processor plug-in was modified to automatically generate the statistics file used by the AVF report generator automatically after the job completes.
- The messages reported during 2.1 ASCII import were modified to improve feedback to the user. The unread card message has been changed to be a warning message, and after the import has completed a message is displayed informing the user if the import was successful.
- The ASCII importer was modified to properly handle the case where a card exists, but only has a comment after the card number.
- The control volume state data was modified to default an atmosphere-only cell to atmospheric pressure when no pressure is defined in a 1.8.6 model.
- The Core package 1.8.6 conversion logic was modified to handle the case where core penetration records have recursive penetration reference values.
- The 1.8.6 conversion logic was modified to ensure that the control rod poison material and the core boundary material defined in the Core package exist as materials in the model after the import has completed.
- The heat structure 1.8.6 conversion logic was modified to support the case where a heat structure references the geometry of a heat structure with a higher component number.
- The 1.8.6 conversion logic was modified to prevent the case where a material component is returned when resolving a non-condensible component number reference.
- Support was added for the default values of the diameter for flash-forward and flash-reverse fields in flow path components.
- The paths indicated by the R*I*F directive for 1.8.6 conversion are converted to use the current systems path separator.
- Subsystems generated from parallel input files during 1.8.6 conversion will only be created if the file contains the initial input record for one or more components, and the name generation logic for subsystems was modified to remove any relative path information that might be included in the R*I*F reference.
Version 1.1.1 - Released 9/8/09:
- The Heat component was modified to read the "SourCF" boundary condition type correctly during 2.1 import.
- The logic that controls when to export the package input flags has been modified to determine when a category level object has data, and has been modified to ensure that the package input flags only written out when needed.

Version 1.1.0 - Released 8/21/09:
- The plug-in was updated to allow a user to store and load multiple sets of initial conditions. Each of the stored initial condition sets will be saved with the model. The editor for managing model initial conditions can be accessed from either the right-click pop-up menu item of the MELCOR model node or in the Model Options property view next to the Condition Sets property. This dialog also includes the ability to retrieve the initial conditions from either a submitted MELCOR job, or from a local PTF file.
- Control functions were modified to disable the additive and multiplicative scale factors for input arguments originating from a logic control function.
- The 2.1 format ASCII import logic was modified to support importing array set card data that does not include indention.

- Several improvements were made to the ASCII import process to better handle errors encountered during a model import.
- The custom dialogs have been updated to resolve problems with adding or removing table values, or closing the dialog while a table cell editor is active.
- The logic that controls how and when package flags, such as CVH_INPUT, are exported was modified to ensure they only appear as required when building a MELCOR model.
- Support was added for control function arguments that reference components by name where the name includes parenthesis.
- The Cavity component was modified to resolve an error importing the cavity layer from a 2.1 ASCII model, and to re supply cavity components correctly.

- The Post processor plug-in was modified to include the full list of MELGEN and MELCOR files when removing files from the model.
- The 1.8.6 import logic was modified to provide support for generating the component names for all of the components inside the model. The user can select to set the name to the package abbreviation, followed by the component number, for example CVH_100, or to just the component number. In either case, the original component name is added to the components description.
- The file filter for the import and export file selection dialog was modified to provide a set of valid input file extensions.
