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().

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)
TEA: bug fix in TH flash, TS flash: uninitialized P in case of single phase result (error: zero or negative pressure)
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
COFE: added configureTEA and configureCORN to start menu
COFE: bugfix in rotating and flipping unit icons; scaling point was wrongly transformed
COUSCOUS: fixed several error messages
COUSCOUS: work-around for overall enthalpy and entropy if not supplied by material
COCO: help file updated
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
CORN: reaction rate & equilibrium constant formulas are now both remembered (only 1 can apply though)
COFE: GetAvailableProps now also adds to the list: pressure, temperature, flow, totalflow, fraction, phaseFraction
TEA: GetAvailableProps now also adds to the list: pressure, temperature, flow, totalflow, fraction, phaseFraction
COFE: error check on obtaining unit operation reports
COFE: unit reports are now shown in fixed pitch font (courier)
COFE: revised unit conversion objects
COFE: kg and moles are now supported when appearing together in a unit operation parameter.
COFE: fractions can now be displayed in percents
COFE: plot series did not update when axis unit was changed
COFE: added mass, enthalpy and component balances to unit dialog
ChemSep: new LITE installer with several fixes
