I0Coin, one of the SHA256 merged mined coins, introduced fixes for the massive-RAM-use problem that family of merged mined coins were all eventually going to notice; the others, maybe including namecoin maybe not I am not sure, adopted those RAM-usage fixes from I0Coin. (Not sure if namecoin addressed that problem yet or not.)

Please elaborate. Is it a client-level fix or protocol-level?. If it doesn't changes anything fundamental (Like Bitcoin that AFAIK, introduced the blockchain and Peercoin that introduced PoS), then it's not an innovation, it's just normal software maintenance.

Goldcoin was the first to introduce a 51% attack defense in 2013.

I found the marketing paper (It's not a whitepaper, and definitely not an academic paper) that claims to have solved the problem. There is a thread in this forum about it which explains how it fails to solve anything and instead serves to expose the incompetence of those developers.

The gen 2 client being released this month will also make GLD the first mineable cryptocurrency written in Java and the first to support multiple currencies.

It may be a first, but writing the first Java client for a mineable cryptocurrency is not an innovation, it doesn't introduces any new technology, it just makes use of existing ones in a obvious way (but I can't discard that it introduces an actual innovation that I'm not aware of).

Nonetheless, thanks for sharing the information.
