I am trying to sort through the various Version properties which can appear in a plist, and determine how to use each one. We use four digits (e.g. 1.2.3.4) for our software versioning, and a change in the final digit implies a new release. In the past, we have put the full version, 1.2.3.4, in the CFBundleShortVersionString. We did this both for our .apps, .pkgs, and .mpkg. Starting with the Tiger version of Package Maker, we started getting a warning that CFBundleShortVersionString should only contain three numbers. This agrees with an Apple document which I found: http://developer.apple.com/documentation/MacOSX/Conceptual/ BPRuntimeConfig/Articles/PListKeys.html#//apple_ref/doc/uid/20001431 -111349 I also found this document with a section called "How Installer Computes a Version": http://developer.apple.com/documentation/DeveloperTools/Conceptual/ SoftwareDistribution/Concepts/sd_pkg_version_info.html#//apple_ref/doc/ uid/20001942-1016661-CEGBFEAA This document suggests that we should set CFBundleShortVersionString to 1.2.3 and SourceVersion to 4, and then the installer will see the version as 1.2.3.4. So this is what we did. Tiger Package Maker stopped showing an error, and the mpkg/pkgs worked fine in 10.3, and earlier versions of 10.4. As of 10.4.4 however, the behavior seems to have changed. If an earlier version with CFBundleShortVersionString of 1.2.3.4 is already installed and we try to install a new version with CFBundleShortVersionString 1.2.3 and SourceVersion 5, this is seen as a downgrade. Likewise, if an earlier version with CFBundleShortVersionString of 1.2.3 and SourceVersion 4 is already installed and we try to install a new version with CFBundleShortVersionString 1.2.3 and SourceVersion 5, this isn't seen as a downgrade or an upgrade - by default the subpackages in our mpkg are not selected (apparently since installer sees the two versions is equal). So, my conclusion is that the installer that is used with 10.4.4 ONLY looks at CFBundleShortVersionString, so we will have to revert to using our full version in that property, despite the warning of the package maker. Could anyone offer any advice on why 10.4.4 installer has changed like this, and whether there is any better solution? This email sent to site_archiver@lists.apple.com
