Unfortunately, yes. The UA database is that old. The project that Divolte relies on for UA parsing no longer provides updates, and has actually broken the update process in a way that when enabling auto-updates, it would overwrite the UA DB with an empty one. Basically, the UA parser project that Divolte uses changed licensing and pursued a different business model. Divolte was never modified to use a different provider. It should, but at present there doesn't really appear to be a viable alternative that can be used off line (i.e. doesn't involve external API calls). I presume many users only map the raw UA string and parse it at a later stage in their pipeline.
