Cannot downgrade installed pkg

See original GitHub issue

Version: 19.5.1
Target: pkg

BundleIsVersionChecked seems to default to true. It would be nice to be able to override this default to allow for downgradable pkg files.

After doing some more research and testing, it seems that the BundleIsVersionChecked option that is mentioned in the pkgbuild manpage is only applicable when using pkgbuild in its stand-alone --root form, and not applicable for the --component form as used in electron-builder.

The effect of this option is to populate or clear the contents of the <bundle-version> tag in the PackageInfo which is contained in the inner pkg. As far as I can tell, there doesn’t seem to be a command-line option to pkgbuild --component which directly controls this tag.

If I manually use pkgutil --expand, edit the inner PackageInfo to remove the contents of the <bundle-version> tag, and then use pkgutil --flatten to repackage, the resulting installer is capable of downgrading an installation.

One really confusing “feature” is that the installer does not give any indication when an attempted downgrade is prevented - it still displays the success screen, and the only way to tell that the downgrade was not actually applied is to examine the installed application itself.

It looks to me like this has been fixed by now. The isVersionChecked option appears to be working correctly.
