Is W3 Total Cache Still Supported?

I’m wondering if anyone knows if the developer is still supporting this plugin? It hasn’t been updated in 2 months despite the issues reported with both version 0.9.5.3 and 0.9.5.4. I haven’t seen any responses from the plugin developer in any of the threads that reported the issues.

We have this plugin installed on quite a few client sites (around 20), and we are still running version 0.9.5.2 because of the reported issues. We haven’t even installed it on some of our most recent sites due to the reported issues.

We’d like to keep using this plugin, but if it isn’t being supported anymore, we are going to have to find an alternative.
