Unfortunately the package upgrade path is quite long - and depends on how quickly these people react. A lot of the development of these packages relies on volunteers, so they might not have time to do everything you might expect.
The developers of the software, in your case drobo-utils, will release a new version. This is usually compiled so it can be installed on the major platforms, with the source code also released.
The Debian package maintainers will monitor existing packages for updates, and check what has been updated. Based on the significance of the update (number of changes, time since last package update) they will create a Debian package for it. Again the major platforms will be done first.
The Raspbian package maintainers will check Debian package updates. There is a possibility that the Debian package might have to be recompiled for the Pi, and create a Raspbian package.
You can then download it. Add some time to each step for testing and you get a long time in some cases.
If you want the latest version, you can try to compile it yourself using the source code from the developers. You might have problems doing this as there might be library differences and other things. If you find problems, and can resolve them, I am sure that the developers will appreciate the feedback.
These are the choices we all face, and usually accept and wait for the package to be updated
