You could download the Beta version (installer or portable) currently available here:
Just add the new Drop Shadow filter to your Text clip, below the Text: Rich filter.
But be aware that this version contains a few bugs (read the post conversation)
Most (if not all) are fixed, but those fixes are not yet available on the Beta version.
Another option, if the Text: Rich filter is not crucial in your project, would be to use the Text: Simple filter instead and add an Outline to your text.
