FlexSim 17.2.1 (August 31, 2017)

Included fixes listed in 17.1.6 below.

Fixed a bug with global variable highlighting and autocomplete.
Fixed an issue with destroying a TE on a network when it blocks space on the network.
Included fixes listed in 17.1.5 below.

Fixed a bug with min() and max() when using distribution functions.
Previously, getting the number of columns in a Global Table using Table.numCols or gettablecols() returned 0 when the number of rows was 0. Column headers and data types are preserved even when there is no row data. These commands now return the number of columns.
Changed operators to not change their incline rotation when traveling on inclines. This will change location calculations if you have advanced logic based on internal operator locations.
NodeListArrays like Object.outObjects can no longer be implicitly cast to an Array. Use the toArray() method instead.
Fixed a bug with animations drawing their first frame instead of their last frame at times beyond the endtime.
Added a special rule for ambient color {0, 0, 0} to not use the ambient color. This change will make shapes with ambient {0,0,0} to appear brighter. Change the ambient color to a dark gray, such as {1,1,1} if you want them to remain dark.
Fixed a bug in the shader that dulled specular highlights with the diffuse texture. This may change how shapes look; they may appear shinier now.
Added the IS NULL and IS NOT NULL clauses to SQL. Math and comparison operators on null values now return NULL. FlexSim's SQL execution engine is now more in line with the SQL ANSI standard regarding null values. Specifically, if you do comparisons or math operations on elements that have null values, this will return null values. This is different than in FlexScript, where a null value acts like 0 in math operations. Also, null values will be ignored in aggregation functions like AVG().
An option to use legacy SQL nulls was added to Model Settings to preserve backwards compatibility. Upgraded models will automatically enable this option, but new models will default to using the SQL ANSI standard for nulls.
Added support for more SQL query operators, such as the case-when-then-else-end operator and window functions. This adds many new keywords to SQL, meaning that if you used these as column names in older queries, they will create syntax errors in the query parser in this version. To fix this, put square brackets [] around the column name.
Changed accessing dynamic label properties to use evaluate() instead of value. For example, consider the following code sample:
    Variant value = current.MyLabel;
In 17.1 and previous, this code was the same as:
    Variant value = current.labels["MyLabel"].value;
In 17.2 we changed it so that this code is now the same as:
    Variant value = current.labels["MyLabel"].evaluate();
The difference is in how FlexScript-toggled node values are retrieved. In 17.1 and previous, current.MyLabel would have just given the text that is the FlexScript code. In 17.2, retrieving current.MyLabel will actually evaluate the FlexScript as code. This is consistent with how table values are accessed. If you have old code that explicitly tried to get the code text with current.MyLabel, you will need to update that code in 17.2 to use current.labels["MyLabel"].value.

AGV

Added unload-to-empty capability to the AGV Process Flow template.

A*

Added a bridge element to the A* network.
Added functionality for collision avoidance.
Improved heat maps for analyzing A* traffic.

Changed the path finding algorithm for the A* navigator. When you tell an A* traveler to travel to an object, now it will behave more like the default navigator. It will calculate a "threshold radius" around the object, based on the object's size. Then it will only travel to the edge of that radius. This makes it work better especially for loading/unloading to/from rack objects. The travel operation won't commit as much to traveling to the center of the object, because that can be left to the load/unload operation, which determines exactly where in the rack to pick/place the item. However, this change does affect how older models work because it changes the routes that travelers take.

Existing models will continue to work with itemtype, but new models should be built using a type label instead of the itemtype attribute and commands.

Process Flow

Added an Assign Released Resource(s) To field on the Release Resource activity.
Added functionality to allow you to Ctrl+Drag activities in an activity block.
Added a right-click menu option and Alt+Click to open the Token View.

Added a Make Array label aggregation type to the Batch.
Added Center in View buttons for fields with pointer data.
Added a name property to the Token FlexScript class.

Fixed a bug with duplicating Process Flows using the Toolbox.

Updated the Pull From List activity so it does not assign a null label when nothing was pulled or the token was released early (manually). Previously, if you used a Max Wait Timer or Max Idle Timer (or some other mechanism) to release a token from a Pull from List prematurely, the label specified in the Assign To field would be created with a value of NULL. Now, the label will not be created. This may break other models that are checking to see if the label value exists. For example, saying objectexists(token.pulled) will throw an exception if the pulled label is never created. This can be easily remedied by changing the code to objectexists(token.pulled?). The ? will cause the value returned to be nullvar when the pulled label does not exist.
Universal Edit fields are now more strict when accessing labels on a token. Previously, typing token.labelThatDoesNotExist would happily return NULL and move on. Now the Universal Edit will throw an exception if the label doesn't exist. This does not include Universal Edit fields that assert labels, for example the Assign To fields.

The new version of Flexnet Publisher requires network license servers to be upgraded. They need to use the latest vendor daemon and update the Flexnet Licensing Service. More information can be found in the license upgrade instructions at https://www.flexsim.com/ftp/LicenseServer/
Updated the Separator's order of events (executing OnEntry before Setup Time) to be consistent with the Processor.
Users of the mesh api should update usage of GL_QUADS to use GL_TRIANGLES instead. GL_QUADS is deprecated and will not work when using the OpenGL Core Profile.
Since the new FlexScript parser compiles to machine code, the order in which parameters are evaluated has changed to be aligned with the x86/x64 calling convention. This means models containing code where parameter evaluation order is important may have changed results. For example, the following code will have different results:

myusercommand(duniform(1, 5), duniform(1, 10))

In the x86/x64 calling convention, parameters are evaluated from last to first. In this case, the duniform(1, 10) call will be called first. Since this call changes the state of random stream 0, changing the order of parameter evaluation changes the result.
The new parser has a stricter grammar for the == and != comparison operators. The types of the operands must be the same or related. For example, the following code will now give compile errors because it is comparing unrelated types:

double x = 0;
treenode y = model();
if (x == y) { }
This version introduces a new Array type, which is an array of variants, enabling a more feature rich array usage. In doing this, we are deprecating the old array types of doublearray, intarray, stringarray, and treenodearray. Specifically, the old array types are now just aliases for the standard Array type. This means that you can now, technically, put a string into a doublearray and vice versa, because they are all just Arrays. Hence we encourage you to just use Array in your code instead of the old array types.

This change has also introduced a problem regarding the Variant type. In previous versions, the Variant could hold each of the four types of arrays, and it had a type value associated with each type, which you could get with the getvartype() command, comparing that value to one of VAR_TYPE_INTARRAY, VAR_TYPE_DOUBLEARRAY, VAR_TYPE_STRINGARRAY, or VAR_TYPE_TREENODEARRAY. Now, however, since we've merged all of those types into one, all of those values would theoretically be the same value, introducing issues if you had code that switches on getvartype(), or in some cases if you had a series of if/else compares on that value. Depending on the specific nature of that code, it would be hard to predict exactly how that code would behave going forward. Thus, we have decided to get rid of those old macros for each array type. Now there is just the macro VAR_TYPE_ARRAY.

If you have existing code that uses the older macros, you will get compile errors when you open your model in version 17.0. We do this specifically so that you will be notified of code that needs to be updated. There are also several pick list options in the process flow module that use these older macros. Version 17 includes update scripts that will hopefully update all of those pick options in existing models to use the new VAR_TYPE_ARRAY macro instead of the old macros.
With the new FlexScript parser, there are now some differences with how the parser compares a null variant to 0. In the old parser, the following expressions applied:

(nullvar == 0) is false
(nullvar <= 0) is true
(nullvar >= 0) is true

In the new parser, the following expressions apply:

(nullvar == 0) is false
(nullvar <= 0) is false
(nullvar >= 0) is false

This brings the <= and >= operators inline with the == operator. However, old code will evaluate differently now. The following expressions apply in both the new and old parsers:

(nullvar < 1) is true
(nullvar > -1) is true
The param() command will now return nullvar if the parameter number is greater than the number of parameters passed to the function (previously it returned 0).

Fixed Fluid Conveyor throwing exceptions on reset.

Updated to OpenGL 3.1. Deprecated OpenGL functions, such as glBegin(), glEnd(), glVertex(), glNormal(), and glTexCoord(), may no longer work correctly on some graphics cards. You should instead use the mesh api.
Changed the way that fixed resources (except the Combiner) receive items when they are being transported in. Previously, when they were notified that an item was being transported in, they would close their inputs and create an event to receive the next item. This would cause problems if the upstream objects had multiple items to send because their routing strategy would work differently when transporting vs not transporting. We have fixed this so that routing strategies will work the same when transporting as when not transporting. This may change the way that old models work because it changes the events that are created, and, obviously, it fixes routing strategy logic.
menumain(), menubelow() and getviewmenu() have changed. Instead of returning a double, they now return a var. Any calls to these commands will need to be updated to use var or the value returned will be 0.
double myMenu = getviewmenu();
Changes to:
var myMenu = getviewmenu();
Previously the Fluid Conveyor would stop conveying if no material was moved into it (ie inputs were closed). This was changed so that the Fluid Conveyor continues to convey the material in it whether any additional material is added or not. Set the conveyor speed to 0 in order to keep the same functionality that was in previous versions.

Conveyor

Fixed issues with the releasetoken(), createtoken(), and releasebatch() commands working differently when running vs stepping.

Changed the way that a token manually released (preempted) from waiting in a task sequence activity manages the task that it's waiting on. Now the task will be removed, and the task executer preempted if currently working on it. This may change older models that release tokens in task sequence activities.

AGV

Added AGV templates to Process Flow.

Fixed bug with way points not firing their OnArrival for redirected AGVs.
Fixed issue with arrival waypoints not firing correctly with non-zero end speed travel tasks.

FlexSim 16.0.0 (March 14, 2016)

Added options to Global Preferences to define which libraries are visible in the Drag-Drop Library and what order they appear in.
Restored the Media Files window (Main Menu > View > Media Files).
Added the ability to assign unique random streams to objects in the model using the command getstream().
Added a Network Navigator Properties window. (Right-click a NetworkNode to access.)
Added a Track Number Field Totals option to the List for stats collection.
Added a 'Values Only' data distinction option to the Excel Importer. This data distinction reads number data and string data from excel cells without regard to the cell's formatting (i.e. dates and times are imported as Excel time values).
Implemented the excelrangeread() command to import a range of cells using the 'Values Only' data distinction.
Added the command convert() for converting model/Excel dates and times.
You can now use keyboard shortcuts for debugging. Next Line -> F10, Step Into -> F11, Continue -> F5, Stop Simulation Clock -> Shift+F5
Updated object statistics to use Tracked Variables for collecting Content, Input, Output, and Staytime statistics. NOTE: These new statistics are only available for new objects. See the Object Statistics backwards compatibility note below for more information.
Made the sql IN clause work if you compare it against a value that is an array.
Added trackedvariable() and inittrackedvariable() commands. This allows tracked variables to be created on objects as labels, etc.
Tracked Variables can now be accessed using the commands get(), set(), inc(), setnodenum(), getnodenum(), getlabel(), setlabel().
Tracked Variables now have a Type which can be Level, Cumulative, Time Series, or Categorical (see inittrackedvariable() documentation).
Tracked Variables can now store profiles (similar to state profiles, the profile stores data on the amount of time the tracked variable was at each given value).
Improved OpenGL compatibility with older graphics cards and Nvidia Optimus cards.

Fixed an issue with copy and paste in the 3D view not maintaining the z position of the copied object.
Fixed the Load From File button in the Edit Selected Objects window to call the firecreateevent on loaded objects.

Updated the Combiner so that items can properly exit through port 0 (such as using a Process Flow Load activity).
Fixed a bug in the Separator state management that was causing it to be idle when it should be blocked.
Changed the max bones per mesh for bone-animated shapes from 60 to 42.
Object Statistics: We have changed the default statistics structure for objects in the library. This will not change the structure of existing models, but will now be different for new objects that are created. Specifically, we have made the standard object statistics--namely input, output, content, staytime, and state--use tracked variables instead of the many different object attributes they used previously. This enables us to add new capabilities, such as a content-vs-time graph that exactly reflects the object content changes instead of an interval-based time graph (use the Tracked Variable vs Time chart or the pin button in the Quick Properties Statistics panel), and the ability for Process Flow Wait For Event activites to listen to object content, input, output changes, etc.

Current FlexSim features will work for both the old and new statistics structures. If you have model or module code that is accessing statistical data directly (such as using commands like get(stats_contentavg(object)) or get(rank(state_profile(object), STATE_IDLE))), this code will continue to work on objects that have the older structure, but it will not work for new objects added to the model. If you want this access to work with objects having the new structure, you should use the getstat() command to get the desired data. The getstat() command will work on both the old structure and the new structure. Below is a list of examples of old statistical access commands vs new getstat() based access.

OLD: get(stats_contentavg(object))
NEW: getstat(object, "Content", STAT_AVERAGE)
(Note here that the getstat() command will return the weighted average that includes the time that the object has been at its current content, whereas with the old method, you had to add that on manually).

OLD: get(stats_staytimemax(object))
NEW: getstat(object, "Staytime", STAT_MAX)

OLD: get(rank(state_profile(object), STATE_IDLE))
NEW: getstat(object, "State", STAT_TIME_AT_VALUE, 0, STATE_IDLE)
(Note here that the getstat() command will actually give you the total time in the idle state. This includes the time in its current state if the object is currently idle. With the old method you always had to manually add that in, i.e. get(rank(...)) + (getstatenum(object) == STATE_IDLE ? time() - get(state_since(object)) : 0);

OLD: getstatenum(object)
NEW: getstatenum(object)
The getstatenum() command works on both structures, so you don't need to change it. Alternatively, you can use getstat(object, "State", STAT_CURRENT, 0) (0 is the state profile)

OLD: getinput(object)
NEW: getinput(object)
The getinput() and getoutput() commands work on both structures, so you don't need to change them. Alternatively, you can use getstat(object, "Input", STAT_CURRENT)

Conveyor

Added Pull and Send To functionality to conveyors. This is done by connecting multiple objects to a single entry/exit transfer.
Added reset position functionality to conveyors.
Added additional events to conveyor objects that can be used in connection with the Wait for Event and Event-Triggered Source activites in Process Flow.
You can now explicitly remove connections from an entry/exit transfer without it being deleted (using the right-click menu). This is useful when sending flowitems to a list where connections are not required.
Straight and curved conveyors now have an optional Virtual Length.
Added Priority and Preempt fields to the Exit Transfer.
Added a Station object. The Station works much like a Decision Point but also allows you to specify a processing time and optionally call operators.
Added States to conveyor objects.
Added a CONV_INFO_GET_ACTIVE_ITEM option to the conveyorinfo() command to get a decision point or photo eye's covering item.

Fixed decision points and photo eyes not saving to user libraries when adding a conveyor.
Fixed conveyor widths not updating when changing conveyor types.
Fixed issues not being able to snap decision points to the beginning or end of conveyors.

Various other bug fixes and improvements to conveyors.

Process Flow

Added a label filter option for tokens in Quick Properties.
Process Flow View now supports a 3D mouse.
Updated activity snapping to allow activities to be snapped to the top of other activities.
Updated the Release Resource activity to allow a reference to a Resource Shared Asset to be passed into the Resources to Release property.
Blocks of activities and display objects can now be saved in User Libraries.
Added aligning functionality to the Process Flow view.
Added snap-to-grid functionality to the Process Flow view.
Speed improvements to drawing.
Assign To properties on the Create Object, Push To List, Pull From List and Create Task Sequence can now either overwrite the assigned label's data or insert the data at the front (creating an array).
When tying the Resource shared asset to a Group, Dispatcher or Array, the Count property now allows you to utilize any number of those objects. This allows you or the experimenter to easily change the number of available resources without objects being added/removed from the model.
Added a 'Do not remove entries from List' option to the Pull From List activity allowing you to utilize the Request and Require fields without removing entries.
Tracked Variables can now be added as labels on objects. This allows you to track the history of its values as well as tie it to a Wait for Event activity as a value change listener.

Fixed issues with the Finish/Sink activity not properly deallocating shared assets if they still had children in the model.
Additional bug fixes and overall improvements.
Fixed exceptions sometimes being thrown when dragging connectors around.
Fixed the Priority field in the Create Task Sequence activity.
Fixed some issues with listening to the OnStateChange of objects.
Fixed an issue that caused large numbers of TE/FR instances to take a long time to reset.
Fixed an issue with the Resource when using a Local type with each instance having a unique resource reference.

The Assign Labels activity used to allow you to pass in a treenodearray or a Group so that it assigned labels to multiple objects at once. Now the Assign Labels only accepts one treenode at a time. Passing in a treenodearray will cause only the first entry in the array to have labels assigned to it. To update any old model utilizing this functionality, loop through each object in the array using the Object from Label Array pick option.

AGV

Updates to AGV travel tasks and preempting.
Some minor bug fixes.

AGVs will now read the end speed of the travel task and use it to determine when to finish the task. This means that if you have an existing model where you defined a non-zero end speed of a travel task, older versions would have ignored this, but now the end speed will be simulated properly. Please see the user manual topic on AGV Types for more information on how the end speed is simulated.
We changed the AGV preemption mechanism so that:
1. When you preempt an AGV, if you do not immediately give it a new travel task, it will decelerate to stop after the preemption occurs. In previous versions the preemption mechanism stopped the AGV immediately.
2. If you preempt an AGV and then immediately give it a new travel task, it will start the new task at the speed it was at before it was preempted. In older versions, a preemption would cause the AGV to immediately stop and then start from speed 0.

Fixed fly paths to run in real seconds when not running with the simulation time.

Fixed resource item state variables are now stored with a custom data structure instead of being stored directly in the tree. This means that if you previously accessed an item's fixed resource state directly through the tree instead of using the commands getitemstate(), getitemsendto(), getitemvar(), etc. your model will need to be updated to use those commands.
Previously, drawfont() would only change the font for one call of drawtext(). Now, calling drawfont() will change the font and leave it that way until it is changed again.
Fixed the 50-flowitem receive limit on the combiner, processor, and rack. This will break old models if your model is dependent on this bug.
Null Variants no longer equate with 0 (NULL). We have added the "nullvar" keyword that equates with null Variants. This could affect models that use getlabel() on a label that does not exist. For more information, see getlabel()'s documentation.
The following commands now take/return Variants instead of doubles:
- nodefunction()
- sendmessage()
- function_s()
- function_n()
- userfunction_s()
- userfunction_n()
- nodefunctionlisten()
- delayednodefunction()
- addbundleentry()
- applicationcommand()
The implications for these changes are as follows:

nodefunction(x, tonum(current)); // BAD CODE
nodefunction(x, current); // GOOD CODE

The problem here is that if you cast it into a number, and on the other side someone wants a node, the Variant thinks it's a number so it won't give back a valid node.
Additionally, all FlexScript and c++ code nodes now return a Variant instead of a double. This also has implications.

return tonum(centerobject(current, 1)); // BAD CODE
return centerobject(current, 1); // GOOD CODE

Here again, if you put something into a number, and then on the other side it wants a node, the variant realizes it's holding a number and won't give back a valid node.
We have implemented an update script that will search the model for this type of code and will update the code to not use tonum(). The update script logs any changes made, putting the log in the node MODEL:/Tools/CodeUpdateLog.

The update script will make the following changes:
1. return tonum(...);
  changes to:
  return (...);
2. For each of the above mentioned commands, the update will search the model for calls to this command, and will update the parameters as follows:
  nodefunction(theNode, tonum(...), tonum(...));
  changes to:
  nodefunction(theNode, (...), (...));
However, the update script will NOT catch the following:

double myVal = tonum(...);
return myVal;

or,
double myVal = tonum(...);
nodefunction(theNode, myVal);

In saying this, please realize that leaving number casts in these areas may continue to work properly, particularly if you the user control both sides of the pass-off, i.e. you have implemented both the caller side and the callee side. For example:

Caller side:
nodefunction(theNode, tonum(theObj));
Callee side:
treenode myVal = parnode(1);

This example should actually work properly. We have deprecated parnode(), parstr(), and parval() and replaced them with a single param() command that returns a type-safe Variant. However, the deprecated commands will essentially try their best to take whatever was passed in and put it into whatever you want. So parnode() will see a number, and try to get it into a treenode. This is the same for returns:

Callee side:
return tonum(myObj);
Caller side:
treenode myObj = tonode(nodefunction(theNode, ...));

Again, this should work, because tonode() and tonum() will essentially try to take whatever is there and put it into a number/node.
Where this will break is where one side is using the type-safe method while the other is not.

Caller side:
nodefunction(theNode, tonum(theObj));
Callee side:
treenode myVal = param(1); // WILL NOT WORK BECAUSE param(1) IS A NUMBER NOT A NODE

On FlexSim's side we have moved all (or most) of our code over to using the type-safe method. Thus any calls that interact between FlexSim code and your code should use the type-safe method. We hope that the proactive update script will resolve this for 99.99% of cases.

Added sql query() support for LIKE, GROUP BY, and non-trivial expressions in the SELECT column clause.
Update the Excel Import/Export to handle importing into bundles and export bundle data.

Expressions can now be used in select columns of an sql query. In order to do this we needed to change our sql grammar to be more compliant with standard SQL. This means you can no longer use the AS clause in a WHERE or ORDER BY statement. You can now only use AS in SELECT and FROM clauses.
Some parameter types for the query command have changed in c++ for more flexible type definitions. This means if you use the query() command in a c++ dll, you'll need to update your dll's headers and recompile the dll. If you use straight c++ compiled code or FlexScript for your query() command, then this should just update.
Removed expertfit. Use Stat::Fit.

Excel Multi Table Import using Automatic Data Distinction will import empty cells as string data, rather than as the number 0.

AGV

Fixed a bug with cpaddlistener() where the control point wasn't passing the right values into the listener callback.
Fixed a bug with custom control point allocations not being cleared on reset.
Fixed a bug where an agv will "jump" if turning around at a path section that doesn't fit its full length.
Fixed a floating point precision issue where the agv doesn't always deallocate a control area on arrival at the next control point and thus causes deadlock with himself when he needs to reallocate the area after turning around for the next task.

Improvement in the Code Editor and other areas where logic is defined through draggable constructs in the library icon grid and sampler buttons throughout popups and picklist widgets to automatically add code, etc. FlexSim commands also display a short description when typing in the code editor.
Picklist fields and many popup fields have code highlighting and autocomplete.
Added some FlexScript implementations of lambda expressions.
Better debugger that allows you to access the tree and other areas of FlexSim while in debug mode. Hovering over variables during debug mode will display their current value.
Panel control GUI enhancements.
Added dashboard constructs that will replace most need for the GUI builder: Users can now do model input through dashboards instead of having to use the GUI builder. Multiple dashboards may be created.
You can now pick which navigator a TE is connected to through their properties page (allows you remove them from all navigators).
New hot keys/accelerators. Ctrl+K and Ctrl+L to resize objects up or down by 5%. Ctrl+W to close the active document window or the active floating window. Updated Ctrl+Tab and Ctrl+Shift+Tab to moved between tabs in the active floating or document window.

- Updated visual studio wizards that work with VS 2012
- A module sample tutorial.
- More Documentation.

Removed 2D Shapes from objects.
Removed the Planar view.
Many open gl commands have been deprecated. The model update mechanism tries to replace all old usages with the new graphics usages. Usually this should work, but in some cases it may not. Note that glBegin(), glEnd(), glVertex(), glNormal(), glTexCoord() have all been completely deprecated, and eventually will no longer work. Going forward you should use the mesh api.
The spaceobject() command has been deprecated and no longer works. In optimizing the graphics engine we realized that a 5-20% refresh rate improvement can be attained simply by removing functionality that is solely there to make the spaceobject() command work. So we've deprecated this command. It is still in the command list so models will update, but updated models that use it will have weirdly drawn shapes.
OnLoad is no longer dispatched by the engine when a project/tree is loaded. If you have custom objects that depend on this event, you will need to use some other mechanism to fire logic when the model loads, i.e. through the OnModelOpen, or through model libraries' OnModelOpen.
Kinematics functionality has changed so that by default kinematics will automatically be pruned off as you pass their individual end times. Note this required a restructuring of the kinematics data, so if your models don't do it on reset anyway, you'll need to re-initialize kinematics in models that are updated from older versions.
In previous versions, getdatastat() was documented incorrectly for the parameter p2 (degrees of freedom). It was actually interpreting p2 as the number of samples in the set, not degrees of freedom. We've fixed that by simply not using that parameter and inferring the number of samples/degrees of freedom from other parameters. This means if you used this command previously it will return different/better results in this version. Also we've changed the way the confidence interval "clamps" to percentages in order to be "safer". Again this affects the values that were returned in previous versions vs this version. See the command documentation on getdatastat() for more information.
We changed the name of the class FlexsimObject to FlexSimObject in-line with our naming scheme going forward. We have implemented an update script that replaces all instances of "FlexsimObject" with "FlexSimObject" in updated models. This means if certain things in your model are dependent on the name "FlexsimObject" (I don't know what that could be, except for maybe dll code that uses the name FlexsimObject) there may be issues with the update.
The assimp 3ds importer is translating some of the files (namely the robot clamps) in a way that is different than our old 3ds importer. It is possible that other 3ds files may need their offsets manually adjusted after updating.
Fixed the per-event 50-flowitem receive limit on the queue. This will break old models if your model is dependent on this bug.
Fixed a bug with deceleration on a network when the task executer is blocking space and is given two travel tasks in a row (this might change old models)
Several attributes were removed, so if you use these attributes in your model you will need to update your model properly:
- Removed Attributes: assertshape, asserttexture, billboard, distcutoff, events, instances, OnCaptured, OnCollision, OnInterrupted, state_graph, state_histo, state_percent, stats_contenthisto, stats_customgraphs, stats_throughputgraph, stats_throughputgraphmaxpoints, stats_throughputhisto, tables, textureaxis_s, textureaxis_t, travelstarttime, traveldirection, travelendtime, traveltimealpha, traveltimebeta, travelvpeak, traveldistance, travelstartx, travelstarty, travelstartz, travelendx, travelendy, travelendz, travelvmax, travelacc, traveldec
- Removed Draw Attributes: ignoredraw, ignorezbuffer, nochildrotate, nochildscale, noondraw, nopredraw, shapetype, reflective, luminous
- Removed Commands: travelto, traveltoupdate, ntravelto, ntraveltoupdate

Developed web accessibility: Opening, configuring, running, and viewing models over the web (using a web browser or handheld device).
Added a new AutoCAD dwg importer.
Added model units and conversion windows. When building a new model, a screen will ask you what model units you will be using. When updating an old model, a screen will ask you what model units were used to build the old model. These settings are stored in the Tools folder of the model.
Modified the picklist and trigger gui widgets to be easier to use.
Created a new node datatype (DATATYPE_BUNDLE) for storing large amount of information efficiently (see documentation of bundle commands).
Implemented a way to package media (3D shapes and bitmaps) into the model file so that you only need to distribute one file instead of a whole directory of files.
Added an embedded command documentation window that can be opened by highlighting a command and pressing F1 in the code window or tree view.
Added a FlexScript call stack to the debugger.
Added a step-in function for FlexScript user commands and nodefunctions in the debugger.
Added a logic builder interface for writing FlexScript logic without writing code. (You can change the default editor back to Code by unchecking 'File > Global Preferences > Environment > Use Logic Builder by Default'.)
Enhanced the flexibility of pull logic and added a new pullitem() command for use in the Pull Strategy trigger.
Improved templates to allow for popup gui windows on picklist options.
Added a mechanism for multiple state profiles.
Changed tables to always show the headers despite scrolling.
Fixed a bug that was messing up the save operation when out of memory.
Toggled the large-address-aware switch so that FlexSim can allocate more memory.
Added floor() and ceil() commands.
Added a switch for hashing the node's subnodes' names for quick lookup.
Added an option in the Labels tab so that labels' values can be automatically reset.
Other various fixes from the development list.

Fixed a critical bug in curved network length calculations.
Fixed issues with gettenetnode() and distancetotravel() on TEs that use "do not travel offsets and block network space."
Made a change to distancetotravel() to base the "back-to-node" distance on the center of the object instead of the object's location.
Changed pulling to no longer override the send-to. Now both send-to and pull must check out to transfer a flowitem.
Changed receiveitem() so that it doesn't behave as if it were pulling.
Made the Rack's OnEntry trigger fire before evaluating the dwell time.
Added a new random number generator to generate seeds based on the replication number for the existing random number generator. Email support if you need a script to initialize the streams of a particular model back to the values used in prior versions.
Added a new overload to the command tonode() to handle large memory addresses. Dlls will need to be recompiled with updated headers to obtain this fix.
Fixed a bug where an endspeed of 0 wasn't properly telling a task executer to continue at full speed at the end of a travel task. The behavior now correctly matches the documentation.
