We just released version 6.2.4 of InstallBuilder our crossplatform installation and automatic update tool. The new release includes several enhancements, such as an improved builder tool on Mac OS X x86 and unattended install support for the autoupdate mechanism. The addition of unattended mode in the automatic update tool means that updates can be applied silently without user interaction. A complete list of improvements can be viewed in InstallBuilder’s changelog.
