MacStories published a short summary of the explanation provided by Growl’s developers about the mess in Growl 1.3.
Unfortunately the summary missed one very important aspect in the devs’ post:
Out-of-date applications don’t work with Growl 1.3 - Due to the changes in Growl 1.3 in order to get Growl into the App Store, some applications currently do not work with Growl and will need to be updated. Some applications have already updated to address this problem. If you are a developer who requires assistance with these changes, please contact us and we’ll be happy to help. Users can use Growl Version Detective to help mitigate this problem, but long term changes need to come from developers.
I’ve used the Growl Version Detective (you can get it from this page) and I haven’t found any application on my system that is compatible with Growl 1.3.
While I do understand the reasons for pushing out the new version as early as possible—and I payed for Growl to support its future, the Growl team has made a terrible mistake: they broke compatibility with older applications. I’m pretty sure they could have thought of workarounds that would not have disappointed exactly the people that hurried to support the dev team.
