⭐ New in install4j 12: A JDK provider for IBM Semeru was added. Semeru runtimes are IBM-branded OpenJ9 JDKs.
You can now select these JDKs for bundling on the "General Settings->JRE Bundles" step.

2/ With the new "Replaced packages" option in the "Package options" step of the media wizards for RPM and DEB media files, you can specify a comma-separated list of package names that should be removed when the package is installed.

4/ Alternatively, you can choose to only alert the user for update installations and offer streamlining only in that case. This corresponds to the behavior in previous versions of install4j.

3/ By default, streamlining offers either a "default" installation or a "customized" installation. The result of the user selection is saved to the boolean installer variable sys.streamlinedInstallation. That variable can be used to conditionally execute other screens and actions.

1/ ⭐ New in install4j 12: Support for streamlining installations has been added.
This builds on the feature in previous versions where screens could be skipped for update installations if the user confirmed an update installation in the "Update alert" form component.

6/ Both launch agents and daemons need an identifier. Launch agents additionally support arguments. Because they can show a UI by default, you can choose to hide them from the Dock when they only perform background operations.

4/ Single-bundle archives now have an additional "Agents and Daemons" step in the media wizard, where you can statically define "launch agents" and "launch daemons".

5/ By default, install4j tries to use the certificate with the maximum validity if you do not select a specific certificate from the keystore. With the new mode, only the private key is loaded from the keystore and install4j tries to find a private key that matches the certificate.

4/ In incomplete or non-standard setups, code signing can fail when the compiler cannot find the certificate or the full certificate chain. To handle these cases, install4j now offers an optional separate PKCS #11 certificate file entry, both for Windows and macOS code signing.

7/ The "Installation scope chooser" form component consists of two radio buttons, one for each option, and is bound to the sys.installForAllUsers installer variable.

6/ Another component that is coupled to this variable is the new "Installation scope chooser" form component. It is part of the new "Installation scope" screen and provides a way to ask users whether to perform a user-specific or a global installation.

4/ The decision whether to set a user-specific or global installation location is determined by the "Installation scope property". The action can also search for previous installations and optionally include user-specific or global installations.

6/ For example, check out the nested bin directory of the install4j app bundle itself. The Finder window shows the command line executables as well as the nested update downloader. In previous versions of install4j, the update downloader would not have been generated.

6/ For one-off style changes, a custom inline style can be configured directly in the form component. To do that, choose the "Define a custom widget style" option and all the relevant style properties will appear as child properties.

5/ Alternatively, widget styles can be applied on the form component level. Form components can have multiple widget styles for their contained widgets. For example, most form components have an optional leading label that has a separate widget style property.

4/ To apply a widget style other than the default style, you can assign it to a screen style. Screen styles in turn are applied to installer applications, screen groups, and single screens, and widget styles are cascaded along with them.

2/ The widgets that are most frequently styled in different ways are buttons. Beyond custom font and custom background and foreground colors, install4j offers different types of buttons, such as borderless buttons, buttons with rounded rectangle borders, or toolbar-style buttons.
