Was Daedalus v 0.8.0 an official release for mainnet?

[danielmain]

After a research done by @disassembler

garnering from S3 and the wayback machine, we released 1.0 in Oct 2017 and 1.1 in Apr 2018 (that was my first involvement in a release) and then switched to 0.10.0 in May 2018

0.8.0 was never released on mainnet, but likely 1.0 or 1.1 had some of the same flaws 0.8.0 had. I think next steps are to identify:
when the user made their first transaction as we can assume that's the version they created their wallet with
what version of cardano-sl was used in that daedalus version

@KtorZ can see when was the first transaction? do you know the public key?
