After the recent upgrade, automatic discounts for members looks partly broken

I commonly set a code for an event such that any logged in user who has a current membership (on one of 5 membership types) automatically sets and can register at the discounted price.

Since upgrading the extension this functionality - based on my tests to date - is partly broken. If I specify just one membership type for an automatic discount, the code seems to work fine. If I specify multiple membership types, then it fails and no discount is auto-applied.

I'm wondering whether it';s calculating on the basis of all membership types need to be true, rather than any?
