Looks like Jamba is not longer supported

Unfortunately, that leaves the addon in limbo, and most of the features aren't working now. The biggest one, for me at least, is the auto/advanced loot feature not functioning. Now, I did have the beta version of Jamba, which... mostly worked, but after updating all addons after the release, it reverted back to the 7.3.5 version. I guess the beta version was removed, so currently only the 7.3.5 release is available.
Does anyone know of an alternative that might help with auto looting, or even a way to get the beta version of Jamba back? Looting anything is becoming a broadcasting spamfest now, even with auto loot on.
On a final note, I'm really glad the ISBoxing team is keeping this program going. Thanks guys!
