Tiny new release with thanks to /u/greypo for highlighting the need for it. In v102, bulk-inviting people to a subreddit would fall over and stop if it came to somebody who was banned from that subreddit, requiring the user to manually remove their name from the list before they could continue. In v104, instead, it treats them the same as if their username was invalid: it logs the reason that it failed to invite them, but then carries on with the rest of the list.
tl;dr: if you didn’t know you needed this feature, you don’t.
