Onyx's Chinese site has detailed information about this new version of the C67ML. The specs section has a nice chart comparing the original Pearl version, the first Carta version and the newest "Carta2" version. Seems like it was released in early January 2016 and the sole difference with the other Carta version is the higher resolution screen.
The site has lots of detailed information for all the Chinese Onyx products like the Boox N96 and the updated Boox T68ML. It also links to order pages on Taobao for each product.
Here's the link. Google translate works well.
