1/ ⭐ New in install4j 12: The "Add a Startup Executable" action has been improved in several ways:
1/ ⭐ New in install4j 12: Support for the Apple Service Management framework.
This should be used for single bundle archives instead of "Install a service" and "Add a startup executable" actions.

1/ ⭐ New in install4j 12: DMGs on macOS can now be styled right in the install4j IDE. You can apply backgrounds, position and the app icon's size manually and add symbolic links like the /Applications directory at arbitrary positions. Also, the bounds of the Finder window can be set.

OMG, I didn't realize how bad this redesign was. No wonder opening a Google app on my phone is like hitting the "I'm feeling lucky" button.
This is just a different kind of monochrome. Bring back color coding 🙏

Many users requested that we publish our artifacts to Maven Central. With install4j 11.0.4 the switch is now complete: all our artifacts are available there. Our custom repository remains online for older releases.

Previously, these artifacts were available from our own Maven repository, which will remain online for older releases. New releases will be published exclusively on Maven Central.Maven CentralMaven Central is the default repository for Maven and also present in most Gradle builds.
