2.1.37
- added new element: VectorCorrelation.
2.1.36
- modfied core. Now all input pipe buffers are purged before start.
2.1.35
- added new element: VectorExpressionEvaluator, more info in the manual
- added new way to measure delay in Delay element: sample count.
2.1.34
- added two more options in Delay element (e.g. ability to measure time using input rate)
- improved Correlation in ScalarCrossTransform
- added option to run first iteration on start in Interator
2.1.33
- added INVERTER option in VectorInstantTransform
2.1.32
- added new options in Iterator
2.1.31
- IMPORTANT NOTE: renamed VectorValue element to VectorProperty, and VectorConstant element to VectorValue. This is to make the naming consistent with other corresponding (scalar/object etc) elements. This change impacts a design when any of those elements are used, manual modification is required.
- added new functions in VectorValue similar like in ScalarValue
2.1.30
- improved the Release Current Design option, added referenced files from Chart Properties and Advanced Properties
- improved DesignInteractor, now the current design is stopped before new design is loaded
2.1.29
- improved vertical scale precision in BarDisplay
- fixed a bug in ExcelFileWriter which occurred when 'Unique name' option was selected.
- improved the Release Current Design option, added referenced files from design settings.
2.1.28
- changed input type from Logical to Scalar in Selector element.
2.1.27
- added new option in Tools menu: 'Release current design'. In Release folder the current design file is put along with all files it references (images, nested designs etc). This way it can be easily used to send that all to someone else without losing any referenced point. Eventually this option will also create executable (self extracting) installer file.
2.1.26
- modified (optimized) ExpressionEvaluator
- added a few new java performance options in bioera.exe launcher
2.1.25
- fixed dynamic pipes in a few elements including ExcelFileWriter and Counter3. They were broken in 2.1.22
2.1.24
- fixed a problem with occasional "BioEra has expired" message which should never occur on a purchased license.
2.1.23
- added Negated output to LogicalMixer
- fixed bug in PRopertyGetter, it wasn't property reading DIGI_FLOAT value
2.1.22
- made the same change in ToggleButton as before in Button, it is now fully refreshed when Reinited from PropertySetter or ElementInteractor
- added new options in NestedProperties, to allow set initial element name and element's icon on designer.
- added new element PipeInfo which provides an information about a pipe, e.g. if it is connected. Can be useful inside a nested design when input connection existence determines its behaviour.
2.1.21
- now Button is fully refreshed when Reinited from PropertySetter or ElementInteractor
- added MidiScale which can be used together with MIDI element to play sounds based on selected musical scale
- added new inputs in DVD player to allow go to Title menu and/or Root menu.
2.1.20
- removed '-diagnostic' command line option
- added new '-cdiag' command line option which will create 'diagnostic.zip' in main bioera folder, then bioera exit immediately.
- now the diagnostic.zip file is created automatically in main bioera folder on any abnormal program exit.
2.1.19
- improvemed PropertySetter to allow set properties on NestedDesign (which contains NestedProperties).
- more improvements in NestedDesign and its dynamic connections
2.1.18
- fixed problem in mode "Reinit Target and followers", it didn't behave properly inside a nested design.
2.1.17
- added option to remember last state in ToggleButton
- fixed option 'Reset local properties' in Advanced Properties of the NestedDesign.
2.1.16
- fixed a problem related to yesterday's change in NestedDesign
2.1.15
- added new options 'Reset local properties' and 'Nested initialization' in Advanced Properties of the NestedDesign. More info in the manual.
- improved/modified Slider, its SET_MAX and SET_MIN functions. If the input value forces the slider to change (to stay in range MIN..MAX), and 'Input sends output value' is set, then current value of the slide is also sent to output.
- made a serious change/improvement in NestedDesign, can impact only mode 'Load/Save local properties'.
2.1.14
- fixed launcher bioera.exe, not all program paramters were handled after 'startup.cfg' option was added a few versions back.
2.1.13
- fixed a bug related to 'Design requires signature' option
- now when runtime is in Edit mode, then selecting an element in Designer will also select chart (if it has one)
- added new folder resource/design for nested design which can be added just like any element (they are on the New Element dialog list)
- added several nested designs in the above folder which resemble BioExplorer's objects, those are for easier conversion to BioEra from BioExplorer
- added ScalarProperty, FloatProperty and LogicalProperty. Those are primarily to hold values used as properties in nested designs. They are similar to XXXValue elements, but simpler.
- added new options in advanced properties of Oscilloscope and BarDisplay to hide horizonal level lines.
- added two new options in NestedPRoperties for dynamic connections
- added option to set password for a nested design in its Advanced Properties. This is useful when default properties are hidden by the existence of NestedProperties element.
- a nested design can be now loaded and run without entered password (but can't be viewed without the password)
2.1.12
- added system setting 'Save before start', if selected then the current design will be saved automatically each time before a start.
- improved/fixed PropertyBuilder. Before, if the mapped properties were the same (from different elements) they were treated as one.
- added advanced options in Slider and BarDisplay
2.1.11
- fixed color bug in VectorDisplay introduced in previous version.
- added new option in Slider: "Input sends output value"
- modified Slider so that it doesn't send an output value when chart is resized
2.1.10
- improved Polygraph, Vector3DDisplay, VectorDisplay, VectorLineDisplay. Colors can be now set as hexadecimal numbers.
- fixed PropertyGetter, digi float type wasn't working propertly
2.1.9
- switched back to java 1.5. Current update 7 of java 1.6 was crashing on Vista (on XP was fine).
2.1.8
- modified ToggleButton. Exchanged ON and OFF labels. 
2.1.7
- fixed a few problems with previous upgrade to java 1.6
- improved 3D options. Removed 'Old 3D library' permanently. Added options to set DirectX as a default (if not set, then OpenGL is default).
- added new optional configuration file 'startup.cfg' located in config folder. It can be used as a substitute (or supplement) to set command line options for 'bioera.exe'
- added new procedure which automatically detects when 3D has crashed. It should never happen, but if it does, then BioEra should be able to start next time (after crash) with 3D option disabled.
2.1.6
- migrated BioEra to newer java 1.6 and latest 1.5.2 version of the 3D library. Caution: this migration may need some more improvement.
- added support for the Lightstone device sold by the Wild Divine Project company. It may not work with older devices.
2.1.5
- fixed warning message: "Element command: Reset element not implemented" and bug in ElementInteractor
- added advanced property Unit in NumericDisplay
- added "Fill Modes" option in Polygraph's advanced properties. Used only with "Scroll to left and fill". If a file mode for a channel is 1, then trace is a line, otherwise (by default) it is solid filled area.
- added Vertical Offsets in Polygraph's advanced properties. It allows to shift each trace up or down.
2.1.4
- added option in Polygraph to place trace labels on the top of the chart
2.1.3
- improved BarDisplay. Added possibility to set/move threshold level(s) using Mouse. The selected value is being sent to new outputs: Level1 and Level2.
- Added new option in Polygraph: Scroll to left and fill. Instead of drawing lines, it fills the areas below the trace.
- Added new input in DVD player: Zoom. It allows to dynamically zoom the window.
2.1.2
- added new option in Tools menu to create usb dongle print.
- added option in BioEra Activation wizard to create usb dongle print.
2.1.0
- Released version 2.1
- added option to buy and run BioEra with USB dongle (with license attached to the dongle, not PC)
- added option in DesignSetting: "Requires signature". When selected, the design is setup to run only on designated instance of BioEra. More details in manual.
- improved dialog with error/info messages, text is now fully displayed.
