3/ ✔️On macOS, the action now uses LaunchAgents instead of LoginItems.
This provides a better user experience without questions due to automation security restrictions.

9/ In addition, MacServiceManagement contains methods for checking the status and unregistering launch agents and launch daemons, opening System Settings in the "Login Items" section, and registering the main bundle itself as a login item.

8/ Registrations are simple method calls that use the identifiers that you configured for the launch daemon or the launch agent:
MacServiceManagement.registerLaunchAgent("com.mycorp.sync.plist");
MacServiceManagement.registerLaunchDaemon("com.mycorp.protocolserver.plist");
MacServiceManagement.registerLaunchAgent("com.mycorp.sync.plist");
MacServiceManagement.registerLaunchDaemon("com.mycorp.protocolserver.plist");

7/ install4j will generate the required files in Contents/Library/LaunchAgents and Contents/Library/LaunchDaemons, but they will not automatically be registered. You need to add logic to your app to alert the user and then register them. This will trigger an OS confirmation.

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.

5/ In install4j, a "launch agent" corresponds to a "startup executable" and a "launch daemon" corresponds to a "service". We've named them with Apple's terminology because you need to read the Apple documentation to understand what is happening in the background to use this feature.

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".

3/ The Apple Service Management framework allows you to manage launch agents and launch daemons in such a way that they are tied to the lifecycle of the single-bundle archive. However, this requires some extra work.

2/ "Install a service" and "Add a startup executable" actions do work for single bundle archives. Unfortunately, when the user deletes the app bundle, their registrations will not be deleted along with the app bundle and that causes problems.

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.

3/ When using PKCS #11, usually both certificate and private key are contained in the keystore. In install4j 12, matching of private keys and certificates has been improved considerably, leading to fewer code signing errors.

2/ In the Windows code signing step, it is now possible to specify patterns for additional binaries that should be signed by install4j. Previously, only binaries generated by install4j would be signed.
