I'm a little confused about the costs

[paolo.moro]

I had 10 minutes of freedom and took the opportunity to update the BIT software, so I browsed the forums, the site etc.. When I got to the price section I got stuck on
“Extend support.”
I wondered: but if I buy version 11.0, don't I have the right - until the next version change - to receive upgrades?
It is easier for me - and correct - to understand the cost of technical support.
But what is meant by “free upgrade period fro 12 months” ?
That every year I should pay 55€?

Thanks

For BurnInTest, new and upgrade licenses include 12 months of support and upgrade protection. Additional support is optional and can be purchased separately. If you choose not to extend your support, you can continue to use the version that was licensed. The license itself is perpetual for the version it was purchased for. The "Extend Support" option can be purchased up until the next major version is released. If the next major version is released and your license is not under support, you'll need to purchase the upgrade option to use the newer version.
