Very good to see it is still being actively supported and developed. I can't see what the panic was about though. I found it relatively easily on the downloads page so maybe they updated it recently? I clicked Downloads, Others and there it was. They will of course give precedence to windows and mac versions as they are the main user audience.
The existing version is great. Incremental updates would indeed be nice. As would support for the newer database formats if not already implemented. I notice on the updates page there are two database file versions at present. I guess this Linux client uses the older format. However, there really isn't much that needs fixing so I hope the improvements bring additional capabilities worth using to the mix and don't detract from the current setup.
