Jason 3.3.0

• Java 21 is used

• Agent's thread is Virtual and not Platform. It allow us to run thousands of agents.

• namespaces may have assigned properties/values. See internal actions .namespace_set_property and .namespace_get_property.

• internal actions .min and .max may have a query as second argument.

• several (minor) improvements in Jason-CLI. About running a project:

  • jason x.mas2h uses gradle to run the application

  • jason mas start --mas2j=x.mas2h runs without gradle. The classpath might be informed using --cp if necessary.

  • jason app compile uses shadowJar to create a jar file with all files and dependencies to run the application.

Jason 3.2.0

The main new feature of Jason 3.2 is the Jason Command Line Interface (JasonCLI). This tools is created to support the creation and monitoring of Jason application independently of IDEs. More information jason-cli/readme.adoc.

• some bugs were fixed
• preliminary support for packages (used by JaCaMo)

The project is cleaned a bit:

• jEdit is removed (JasonCLI and third party IDEs are proposed)
• Ant is replaced by Gradle
• Java Web Start is not used anymore
