That’s because Veeam have a two-stage sunset policy for support.
You may be thinking “I haven’t seen an update for a long time for these products, I thought it was end of life anyway”. New versions for each of the above products are currently expected in 2023, so they will all cease receiving support at some point. As Veeam don’t announce the release dates in advance (normally) for these products, at any point Veeam could release the next version, causing these versions to cease receiving support. The 2023 calendar year has the following products reaching end of support status for the following products. It’s that time again to remind everyone that all good things run out of support eventually.
