What's New

(green star) New Feature      (star) Non-Critical Bugfix      (red star) Critical Bugfix

Issue Description Version
(green star) Improved "New"-"New" scenario. LemonTree prior to 2.1.4 always reported a conflict when an element with the same GUID was new in both branches. Starting with release 2.1.4 LemonTree will compare the elements properties and won't report a conflict if the elements are equal. For example with .xmi imports elements can be new with the same GUIDs in both branches. 2.1.4
(green star) Support of Tagged Value Types LemonTree now also supports UML Types → Tagged Value Types. 2.1.4
(green star) Removed diagrams from "Impacted Elements List" Changed diagrams will no longer appear in the "Impacted Elements List". They still can be found in the "Impacted Diagrams List". 2.1.4
(green star) Diagram generation We improved the speed of diagram generation in the "Diagram Viewer". 2.1.4
(green star) Improved filtering Filter now supports filtering for "GUID" and "ChangeIn". Take a look here: Filtering Impacted Elements / Impacted Diagrams and the Tree Browser. 2.1.4
(green star) Recent filters LemonTree stores recent filters in the suggestion box. 2.1.4
(green star) Stereotypes in Tree Browser LemonTree shows the Stereotypes of elements in the Tree Browser (as known from EA in Project Browser) 2.1.4
(green star) Restructuring Burger Menu We restructured the Burger Menu for better understanding. 2.1.4
(star) Session files Also child elements are selected again when loading a session. In previous version the parent element has been selected. 2.1.4
(star) Removed diagram type from list Also in the Impacted Diagrams List the type of the diagram has been removed (similar to the elements in Impacted Elements List in version 2.1.0) 2.1.4
(star) Support of scaling There was an issue when the display had scaling activated. 2.1.4
(star) LemonTree starting twice In some rare conditions LemonTree started twice. This is now fixed. 2.1.4
(red star) Support of relative paths LemonTree had problem when VCS integration delivered relative paths to the models. This is now fixed. 2.1.4
(green star) Performance improvement We improved performance on writing models. Also take a look here: Performance and Memory 2.1.0
(green star) Extended session files Session files also save selected elements from Impacted Diagram/Elements list. 2.1.0
(green star) Icons in LemonTree We consolidated the icons of elements to look like in EA 13. We also found some icons which were displayed wrong (like "linked document"). 2.1.0
(green star) Editing of properties More properties (like "Code") can be edited now. But we restricted others (like "ModifiedDate") where modifying makes no sense to us. If you miss the editing possibility for a special property please contact us. 2.1.0
(green star) Displaying of UmlType/EaUmlType in Impacted Elements/Diagrams lists Because of displaying too much information (like "UmlType" after the elements name) readability of the "Impacted lists" has suffered. We consolidated it: The type of the element is now visible via icon (like in EA). There is also a tooltip for the icon to retrieve the element type. 2.1.0
(green star) Improvements of Tree Browser The Tree Browser provides better visual information where an element belongs to and which elements experienced what kind of changes in the merge preview. 2.1.0
(green star) Moved elements visualization We removed the FullQualifiedName from the Property Viewer and replaced it with moved from/to indicators to improve understand better understand moved elements. 2.1.0
(green star) Support of "Keywords" Keywords are now supported by LemonTree. 2.1.0
(green star) "Session information" introduced The new entry "Session Information" in the "Burger Menu" shows information about session like base model, session type and more. 2.1.0
(green star) Automatic merge can be aborted When LemonTree is integrated in VCS it shows the dialog "LemonTree is thinking". Users can now abort this dialog. 2.1.0
(green star) Position/size of UI components LemonTree now remembers the position/size of UI components (like Property Viewer, Tree Browser, ...). 2.1.0
(green star) FIPS compliance When implementations of cryptographic algorithms are not FIPS compliant on customer machines, LemonTree was not able to start. We now set enforceFIPSPolicy to "false". LemonTree doesn't use MD5/SHA-2 in a security relevant context. 2.1.0
(green star) Visualization of diagrams We improved visualization of diagrams in Diagram Viewer. 2.1.0
(star) Licensing improvements LemonTree 2.0 introduced a new licensing component. LemonTree 2.1 provides better feedback and also fixes some minor issues. 2.1.0
(star) Status of requirements EA saves the "status" of requirements redundantly in the DB ("PDATA1" and "Status"). Depending on EA versions it can happen that this information is not consistent but conflicting. Older versions of LemonTree consolidated these fields. LemonTree 2.1 does not do that any more. 2.1.0
(star) Improvement on stereotype handling EA knows different ways to store stereotypes. LemonTree has been improved on assigning stereotypes to elements. This has impact when using profiles/MDG-technologies and visualization in the Properties Viewer. 2.1.0
(star) New action types in EA 14 EA 14 introduced new action types ("Reduce" and "Unmarshall") which older LemonTree versions did not know about. LemonTree 2.1 handles them correctly. 2.1.0
(red star) Internal requirements Internal requirements are cut off to 256 characters. This is fixed in LemonTree 2.1 2.1.0

Known issues

  • Constraints of Messages in Sequence Diagrams get lost.
  • SaveFileDialog prompts twice when overriding a file (for example file dialog "Start Merge" and selecting an existing file). That does not happen on Windows builds prior to 10.0.17763. It seems to be a bug in .NET.

  • N-ary associations with navigability are not supported properly.

  • Link to composite diagram get lost on activities.

  • Multiplicity properties (Upper bound, Lower bound, ...) of parameters of interactions of sequence diagrams are not diffed/written.

  • There is a problem when LemonTree is started via Commandline and relative paths. Working on the fix. Fixed in 2.1.4
  • LemonTree cannot start: Due to updating a component LemonTree requires a new version of Visual C++ Redistributable 2015 Packages which is not delivered with the setup with 2.1.0. We're currently working on a HotFix for it.
    A manual install of the package may be required if it's not on the system (it is installed with various types of software). Find the package here:
    Fixed in 2.1.1
    Note: Problem still exists in LT 32Bit version.

Not supported EA features

LT doesn't diff these features:

  • Default diagram
  • Project Tasks/Issues (Can be found in Ribbon "Construct" → "Project" → "Status" → "Project Status (Tasks & Issues)"
  • UML Types → Tagged Value Types  Fixed in 2.1.4
  • EA Security: Configure → Security
  • Testing
