Following along from last week’s 1.8 release, we’ve released a 1.8.1 patch release today to address a regression logged in bug 771825. You can download the SDK directly in either zip or tarball format.

This bug was reported by Yonatan Ben-Nes on the Jetpack google group. The problem can affect any add-on that uses the exports.main() function in main.js and attempts to react to the property options.loadReason:

exports.main = function(options, callbacks) {
    if (options.loadReason === 'install') {
        // do something
    }
};

In SDK version 1.8 this code will fail with an error ‘options.loadReason is undefined’. A workaround with 1.8 is to look at self.loadReason instead, however we have fixed this regression and restored the original behaviour in Add-on SDK version 1.8.1.
