The device had a number of updates since its release, so you'll keep receiving them one by one. The most recent firmware version is 47.1.A.12.119, so if your version is below this you may be receiving more.
You can skip all of them by performing a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Don't forget to backup using Xperia Companion, but preferably without adding apps or settings to the backup.
You can know your current firmware version from Settings -> System -> About phone -> Build number.
You can check if you're getting incremental updates or not from Settings -> System -> Software update -> tap on the 4-dots icon on the top right corner -> Update history.
