Like others, I signed up for "Early Access" to the Logos Pro subscription plan. Apparently, subscribers will be given early access to new updates, features, etc. as they are released. So far, I think the only new items I have received are those promised in the original announcement. (It turned out that of the 400 new books promised, I already had permanent licences for 240!)
I've been asking "Customer Support" for a URL/link which would list other new items as they are released. CS seems unwilling or unable either to understand the question, or to provide an answer.
May I respectfully suggest that as part of the roll-out of the subscription regime, that Logos provide a subscriber updates page which is updated whenever a new feature, bug fix, etc. is released? If one already exists, please let us know where to find it.
