Larger training sets, HeroThemes licenses, and bot-limit messaging.

Improved: Bots can hold up to 5,000 training items. The previous lower limits on website and WordPress imports were removed.
New: Enter a HeroThemes license key under Billing to claim the complimentary Pro entitlement that comes with it.
Fixed: Reaching your plan's bot limit now shows a clear message and the upgrade path instead of an error.
Fixed: Answers when a bot's sources include large uploaded files, which could previously drown out other sources.
