jUML is a UML diagram application that is capable of reverse engineering Java source code to create relationship diagrams, source code generation based on a user created UML diagram, and saving/restoring of jUML projects.

System requirements:
-

Enhancements
- This is a working release. You can either import files to show relationships or create a new diagram and generate/test code and save the project.

BOUML is cross-platform UML 2 tool box that runs under Mac OS X(Intel), Unix/Linux/Solaris, and Windows.
BOUML is very fast and doesnt require much memory to manage several thousands of classes, see benchmark.
BOUML is extensible, and the external tools named plug-outs can be written in C or Java, using BOUML for their definition as any other program. The code generators and reverses are ones of the pre-defined plug-outs included in the BOUML distribution.

Main features:
- it is free
- it runs under Mac OS X, Linux/Unix/Solaris, and Windows thanks to Qt
- it allows to program simultaneously in C , Java, Php, Python and IDL
- thanks to a full access to the generated forms, you are the master and you decide what must be generated
- it is extensible, and the external tools may be developed in C or Java, using BOUML for their definition as any other program.
- it is very fast and doesnt require much memory to manage several thousands of classes

Enhancements
- Browser search allows now to search for elements depending on their stereotype.
- The menu miscellaneous has the new toggle completion in dialog, it is set by default to be compatible to the behavior of the previous releases. When it is set and you enter a string in a list of choices (combo box) in a dialog, an auto completion/search is done, note this one is non case sensitive (Qt limitation). If you dont like this auto completion/search, unset the toggle.
- Internal extension of the Plug-out API for Java Roundtrip.
- C++ Generator 2.13
- A dependency stereotyped friend produced a wrong code in case the target class was a template, fixed.
- Follow the new API.
- Plug-out upgrade 1.13
- A crash occured when you upgraded an old plug-out without Python management, fixed.
- Follow the new API.
- Java Roundtrip 1.0
- New plug-out, please refer to the documentation
- C++ Reverse 2.10
- Java Generator 2.17
- Java Reverse 2.13
- Java Catalog 2.12
- Idl Generator 2.10
- Php Generator 1.5
- Php Reverse 1.3
- Python Generator 1.1
- Roundtrip body 1.8
- Follow the new API.
- XMI Generator 1.4.6
- When a parameter of an operation doesnt have type the token UML:Parameter wasnt closed, fixed.
- XMI2 Generator 1.10.2
- The base type of a class stereotyped typedef is now produced in an extension form supposing you ask for them

UML implements UML statecharts in C++ and Java. Next to the standard elements of FSMs, hierarchical and concurrent states are as well supported as pseudostates, segmented transitions, timed events and an eventqueue using a thread pool.

Main features:
- Very easy to use API (See documentation for details)
- Implemented in C++ and Java
- Does require only a very small amount of memory
- Complete object-oriented design (all elements are real objects)
- Parallel usage of the statechart infrastructure. Runtime specific data is encapsulated in a small object.
- Support for many elements of statecharts
- Simple, hierarchical and concurrent states
- Start and final states
- History and deep-history pseudostates in hierarchical states
- Fork- and join pseudostates for concurrent states
- Segmented transitions using junction points
- Transitions can cross borders of composite states (implicit entry/exit)
- Entry, do and exit actions in states
- Events, guards and actions for transitions

System requirements:
- Java

Enhancements
- Fixed a ConcurrentModificationException bug when handling timeout events.
- Fixed shutdown procedure when the created threads are non-deamon threads.

SeSAm (Shell for Simulated Agent Systems) provides a generic environment for modelling and experimenting with agent-based simulation. We specially focused on providing a tool for the easy construction of complex models, which include dynamic interdependecies or emergent behaviour.
SeSAm agents consist of a body, that contains a set of state variables and a behaviour that is implemented in form of UML-like diagram. Based on an extensive number of primitive components, a user is able to design a simulation graphically without knowing the syntax of a traditional programming language.
The model specification is executable in the same environment and the dynamics of this simulation may be observed. As there are freely configurable instruments for gathering data and scripting options for constructing simulation experiments, SeSAm is a highly valuable tool for MAS simulations especially for complex models with flexible agent behaviour and interactions.
As a graphical interface for implementing a simulation model, SeSAm provides built-in animation capabilities, tools for collecting and analyzing protocol data, etc.. The simulation tool is domain-independent. Existing models vary from the simulation of social insects to bussinsess process modelling. Even scientists without traditional programming experience are able to build and experiment with multi-agent models. Visual editors allow to describe the agents and their behavior. After building the model you can run the simulation and observe the animation and on-line evaluation curves. All steps can be accessed in a visual way!
Main features:
- Easy visual agent modelling,
- Flexible environment and situation definition,
- The whole power of a programming language,
- Integrated graphical simulation analysis ,
- Distribution of simulation runs in your LAN.
Enhancements:
- Improved Error Report System.
