This release adds a dark mode, support for underlining and italics in class diagrams and changing the font, and a customizable user guide.

User-Facing Changes

• Added a dark mode (#538). (View | Dark Mode)
• Added support for underlining and italics to indicate static or abstract members is now available (#512). In class diagram nodes, use a pair of slashes to mark text in italics (e.g., /abstract/), and underscores to underline (e.g., _underline_).
• Add option to change the font family (#531) (View | Change Font).
• Reorganize the website, with the posts in the user guide organized by different categories (#530).

Minor Improvements

• The application is now built on Java 21 (#523 );
• Fixed Notification to JetUML icon on Taskbar (#524)
• Fixed MenuItem mnemonics key binding conflict (#540)
• Fixed Connection point calculation error in State Transition Diagram #547
• Removed unnecessary Scroll Bars in Text Areas #553

Refactorings

• Redesign StringRenderer Class #528
• Run geometry tests only on windows #542

Installation on MacOS

Pre-built binaries of the self-contained application are not (yet) available on MacOS due to packaging constraints for this platform. We plan to support this in the near future. In the meantime the application can be launched as a thin jar.

Integrity

You can verify the integrity of your JetUML download by computing its SHA256 hash or by verifying the corresponding PGP signatures. The files are signed by Martin Robillard (public key).

This release adds a notification system with live reporting of semantic errors when diagramming.

User-Facing Changes

• New notification system (#508, #519, #520). Confirmations and errors now get reported as toast notifications at the bottom left of the application window. Use the menu View | Notification Duration to change the notification time. A notification time of zero disables the notifications.

Bug and Other Issues

• Fixed Files with newlines cannot be opened (#515);
• Fixed Point node does not get deleted when corresponding edge is cascade-deleted (#522).

Release 3.6 provides a major redesign of the diagram persistence and validation logic, intended to facilitate integration with other tools.

User-Facing Changes

• The format of JetUML files is now formally specified and documented (#488).
• The stacking order of nodes is now preserved when saving and loading files (#503), which solves the problem of notes disappearing behind other nodes.
• Improved the placement of middle labels for segmented edges (#504)
• Automatic file version migration between 2.x and 3.x has been decommissioned (#468).
• The error reporting for invalid files has been improved (#499, #500)
• Fixed Small visual glitch with aggregation line in class diagram (#474).
• Fixed Package node loses position when last child node unlinked (#505)

Design Changes

The JSON de/serialization code has been entirely re-written (#486). Formerly relying on the legacy org.json library, the JSON parsing code is now simpler and more robust, and tailored exactly to the needs of JetUML. The code to validate UML diagrams has also been completely redesigned to unify the validation done following user gestures with the validation done when loading files.

Installation on MacOS

There remains an unresolved problem packaging the application binaries for recent versions of MacOS. We plan to implement a solution in the near future. In the meantime the application works when properly launched as a thin jar.

Integrity

You can verify the integrity of your JetUML download by computing its SHA256 hash or by verifying the corresponding PGP signatures. The files are signed by Martin Robillard (public key).

Design Changes

This is a maintenance release that incorporates a major redesign and simplification of the diagram rendering functionality (#462, #465, #466, #467, #470, #471, #473, #478, #483, #484 ). A description of the new design is available as part of the architecture documentation.

User-Facing Changes

• Pasting into sequence diagrams is now explicitly disabled (#482)
• Fixed Edges don't connect to package node boundaries when connecting north (#469)
• Fixed Endless loop when drawing class diagrams with interleaved control-flow (#463)

Installation on MacOS

There is an unresolved problem packaging the application binaries for MacOS Ventura. As soon as we find the fix we will post the binaries here. In the meantime the application is reported to work when properly launched as a thin jar.

Integrity

You can verify the integrity of your JetUML download by computing its SHA256 hash or by verifying the corresponding PGP signatures. The files are signed by Martin Robillard (public key).

New and Improved Features

• This release features new layout algorithms for the class diagram (#375). The algorithms leverage a number of heuristics to keep diagrams clear by avoiding overlap and edge crossings, while selecting intuitive-looking paths and more effective label placement (#446).
• In sequence diagrams, we no longer delete the implicit parameter when a constructor call is deleted (#437);

Bug Fixes

• Cannot select overlapped implicit parameters in sequence diagram (#438);
• Drag package content to bottom of viewport. Subsequence dragging misbehaves (#445)

Code Refactorings

• Refactor the PersistenceTests (#439)
• Update Checkstyle style file to 8.44 (#440)
• Code Modernization and Cleanup (#456). JetUML now runs on Java 17.

New Features and Improvements

See the User Guide for details.

• It is now possible to change the size of the text in diagrams (#426)
• Using the shortcut key combination Ctrl-Q inserts UML stereotype delimiters (#434)
• Field nodes in object diagrams have a tighter visual layout (#428)

Refactorings

• Node position is no longer stored as a property (#427)
• Enums are now used to define property values (#429)

Usability Improvements

• The middle labels of edges in class diagrams are now centered properly (#409)
• Fixed a bug that made labels shift when changing the selection (#402)
• The intersection between edges and rounded rectangles (state diagrams) and ellipses (use case diagrams) are computed precisely (#401)
• The labels of actor nodes are now centered in use case diagrams (#419)
• The webpage for the user guide is static and loads faster (#398)

Code Improvements

• General cleanup of the geometry code (#396)
• The constraint checking code for edge creation has been improved for run-time performance (#416)
• The design of the code that renders strings in diagrams has been improved (#413, #422)

This release integrates three features:

• End-user documentation available as an optional "Tip of the Day" or as a whole through a web page #332, #386, #394;
• The ability to open files passed as argument, which enables the "open with" feature available on most operating systems #382;
• The ability to zoom in and out in diagrams #328;

This release fixes a few leftover problems from 3.0.

Usability Improvements

• Fixed bug causing the selection of fields in Object diagrams to changes their relative order (#377)
• Fixed insufficient name padding for some class diagram and use case diagram elements (#379)
• Fixed bug causing version migration between compatible versions.

Code Improvement

• Removed unnecessary parameter in edge segmentation code (#378)

This release fixes a bug that prevented the creation of field nodes in object diagrams (#376).
