COFE/TEA: only mole basis is allowed for .Dmoles for extensive properties
COFE/TEA: corrected mass/mole conversion for property.Dmoles with property being scalar mixture property (e.g. density.Dmoles). Chain rule applies for mixture molar weight; this requires calculation of property during mass conversion (during GetProp() call)
TEA: checking for unique names when renaming compounds
TEA: fixed compound renaming; old name was still used in some cases
TEA: added Dmoles for all properties for which DmolFraction was available. Dmoles is back-calculated from DmolFraction values
COFE: crash when reading document with multiple property packs in which the first one failed to load
COFE: crash after trying to plot series that does not have pp attached (reference to document's log gets destroyed)
TEA: correction to CorE virial EOS component mapping
TEA: correction on all entropy calculations, removed ideal entropy, replaced entropy from gamma by entropy from fugacityCoefficient
TEA: corrected documentation on entropy
COFE: fix for axis scaling in plots with series that has all data missing
TEA: updated eantoine.lib so that names match the ones in the pcd files; suppresses warnings
COFE: fixed small issue with storage of dimensionality preferences
COFE: fixed hotkey for solving individual unit operation
COFE: for MO and simulation context COM objects: force destruction if not properly Release()d, plus reporting to the end-user (COFE will exit if all objects are released)
COFE: several fixes for plots with logarithmic axes, and zero or negative values
TEA: default tolerance has been decreased to 1e-6. The default maximum number of iterations has been increased to 75.
TEA: added implementation for pseudo properties for cubic equations of state, infeasible regions
TEA: implemented inside-out equilibrium calculations for VLE equilibrium server
TEA: added heat capacity calculation routine from Cp = dH/dT. This is now the default Cp routine
TEA: improved consistency check on entropy, enthalpy and heat capacity
COFE: fix, steam dialog was showing mass fraction compositions for non-existing phases
COFE: allow H-VF and S-VF flashes from within the stream viewer
TEA: When CorE Hvap is out of temperature range, it is still used with a warning (previously Pitzer was used instead, but this makes for a discontinuity that is not desired).
COFE: bug fix in maximum number of newton iterations
COUSCOUS: overall enthalpy calculations on a duplicate of an inlet material within AspenPlus 2004.1/patch:CP-4, still results nonsense: the cause seems to be that phase compositions are not copied by AspenPlus' material::Duplicate().
ChemSep: new LITE installer with several fixes

Changes since version 1.02 beta:

Installer: the data\UnitIcons\Vessels folder was not installed, this caused the icons for the flash and the FCR to be missing
COFE/CORN: using the new v1.1 CAPE-OPEN IDL with new definition for ICapeThermoMaterialContext rather than ICapeThermoContext
COFE: fixed memory leak when failing to restore a saved thermo pack
TEA: added universal constant speedOfLightInVacuum and compound constant SMILESformula
COFE/TEA: revised props.ini format and content for compliance with 1.1 thermo standard
COFE/TEA: revised mass/molar/total conversion of material object
CORN: bug fix after initializion failure: initializing as empty reaction package
COFE: added phase information page in flowsheet configuration dialog, will contain the v1.1 phase information
COFE: items no longer show bold or non-bold in the CAPE-OPEN component selection dialog (which used to indicate the version string was set to 1.0)
COFE: added T and P to calculator results of equilibrium calculation
COFE: bug fix: error correction in mimicked properties: removing properties from list at repeated calculation caused results to equal first call (specifically an issue for TX, PX plots, as well as overall enthalpy/entropy plots)
COFE: bug fix in properties available for plotting: mimicked bubble and dew points were not included in the list
COFE: v1.1 thermo still disabled, untested

Changes since version 1.01 beta:

COFE: many BSTR values were over-allocated by one wide character. This is now fixed, and resolves string comparison issues with all PMC implementations that depend on the string length as reported by SysStringLen rather than lstrlenW. This includes all PMCs written in VB 6.0. It resolves problems loading Infochem's Multiflash as well as Aspen Properties 13.2.
COFE/TEA: Changed solubilityIndex and solubilityProduct properties into vector properties (were previously in props.ini as scalar properties)
COFE: added code for being able to read files that stored properties that were previously defined in a wrong format
COFE: bugfix: old documents failed loading in case of properties that were no longer present
COFE: added dewPointTemperature, dewPointPressure, bubblePointTemperature, bubblePointPressure to the list of properties exported by a material if they are mimicked by the PME rather than exported by the property pack used by the material
COFE: corrected display of matrix values in stream dialog when using material types with fewer compounds than available in document
CORN: implemented IPersistStream on instance of reaction package; the reaction package did not yet store itself into the COFE document
CORN: bugfix: crash on passing empty reaction ID
TEA: you can now restore property pack templates from other property pack templates. This is useful for creating copies of property pack templates (create a new one, restore from an existing one)
TEA: bug fix in making property pack name unique: wrong number was used
COFE/TEA: bug fix: crash on suspect value warnings without basis in MO SetProp
COFE/TEA: changed limit for warnings on suspect values in MO SetProp to 1e15 (before: 1e10)
COFE: when plotting T or P series, no longer evaluating series data if used fractions do not add up to unity
COFE: corrected error in drawing lines in plots with missing points
COFE: added context menus to graphs
COCO: several corrections to help file
COFE: added normalize and remainder context menus to composition overrides for temperature and pressure plots
COFE: quicker response to aborting solve using Ctrl+C (derivative and equilibrium calculations are skipped in case of abort)
COFE: possibility to abort calculations in graphs
COFE: added property/equilibrium/reaction property calculator
CORN: added load and store to reaction pack edit dialog (like in TEA)

Changes since version 1.00 beta:

COUSCOUS: invalid registration of the compound splitter is fixed
COFE: memory leak fixed in case of failure of thermo system
COFE, TEA, COUSCOUS: more elaborate error in case of ECapeUnknown and no error interface
TEA: bug fix in pH flash, pS flash: uninitialized T in case of single phase result (error: zero or negative temperature)

COFE: bug fix: parameter spec was obtained using QueryInterface() rather than get_Specification()
COFE: shortcut keys to menus
COFE: added Zoom-in, Zoom-out menus

TEA: get_PhaseIDs is no longer returning the overall phase as part of the list
COFE: dropped requirement of at least 2 compounds per material type, now is at least 1
TEA: dropped requirement of at least 2 compounds per property pack, you can now make a zero compound property pack
COFE: updated document format for future backward compatibility
COFE: revision of material object; properties like enthalpy can now be stored in J/mol, J/kg or J/s; conversion no longer takes place at SetProp, but at GetProp. Solves a lot of issues regarding order of specification.
TEA: revision of material object; properties like enthalpy can now be stored in J/mol, J/kg or J/s; conversion no longer takes place at SetProp, but at GetProp.
TEA: TP flash failure was not always detected
COFE: added possibility to specify overall enthalpy or entropy from the stream dialog
CORN: new reaction rate wizard
COFE: the material object is now able to CalcProp() dewPointPressure, bubblePointPressure, dewPointTemperature, bubblePointTemperature if there is no support for that in the property pack
COFE: the material object is now able to CalcProp() overall enthalpy/entropy/volume if there is no support for that in the property pack
COFE: when using Validate() on the flowsheet, each unit operation's validate is now explicitly called (formerly the results of that were cached)
COFE: bugfix in importing parameter dimensions: crash at less than 6 numbers could have occurred
CORN: accepting no basis as mole basis
COFE: support for plotting reaction properties vs T or P
CORN: many corrections to actual property calculations
