Butler 4.1.14 is now out, and if you’re running OS X 10.8.2, it’s a very highly recommended update. That’s because the main purpose of this release is to work around a bug that Apple introduced into inter-application communication in 10.8.2. The result of this bug is that Butler would appear to hang at times, typically when it was talking or listening to iTunes.
We’ve worked around that bug, and fixed a couple of other things, and the result is Butler 4.1.14. Get it via in-app updating, or by downloading it directly from the Butler page here.
Obligatory footnote: Yes, we’re still planning on releasing Butler 5. We don’t yet have a beta or release date, but as soon as we have either, we’ll make sure everyone knows about it.
