V2019 vs v2021. Reason(s) to upgrade?

Am (happily) running VC2019. Curious about any changes in v2021. Any compelling reason(s) to upgrade

Great news! - I don’t believe in rocking the boat.
We’ve fixed quite a few bugs, so some have needed to upgrade when they run into problems.
There have been a number of improvements, for a list of some of them, search for these exact phrases:

Announcing update for VC 2020 and VC Lite 2020
Announcing v1.22 of VC 2020 / VC Lite 2020
Announcing VoiceComputer 2021 and VC Lite 2021

Thanks for the quick reply Ron.
