"We have seen a couple of questions come up on the Inventor newsgroup around the new Update mechanism that the Inventor team has initiated and whether Updates replace Service packs going forward.
Let it be clear that Inventor will still have Service Packs going forward! As its name implies, Updates are intended to deliver critical updates (formerly Hotfixes) on a more predictable schedule. Think of it as a bundle of Hotfixes.
Service Packs allow us to deliver more complex changes but require more time to produce and verify than Updates. Like Hotfixes, Updates only affect targeted areas of the product associated with particular issues.
There are a couple of other differences between Service Packs and Updates:
- Service Packs can be included in deployment images, Updates can not
- Service Packs increment the build number, Updates do not
- After applying an Update you will neither see a difference in the build number nor a change to the release name in the About dialog.
In order to verify if you have Update1 installed, you need to go to the Windows > Control Panel and use Programs and Features and View installed updates."
