Hey James,
I can't remember, which app are you building?
You can share the name or the public key.
I can look into the $250->$350 renewal.
Regarding your question, yes, Avo 3 is still supported and will receive updates (bugfixes and security updates). We cut three new security releases this month alone.
Yeah, you can't beat that early, grandfatherered price.
Avo has come a far way from what it was then.
We are not going to change the pricing structure for Avo 3.
The way we handled price increases so far was to not force our existing customers to upgrade and grandfather them in as it happened in your case.
Let me know if you have any more questions
