What did Aptos used to be called?

Excuse me, I was just going through some cryptocurrency news and came across the name "Aptos". It seems to be a fairly new project in the blockchain space, but I'm curious to know if it had a different name at some point in its development. Can you shed some light on what Aptos used to be called, if indeed it had a different moniker in the past? It would be quite insightful to understand the project's origins and how it evolved into what it is today.
