The Changelog is a bit succinct. From the NewStuff file:

2. There is a new option called smtp_return_error_details, which defaults
    false. In the default state, Exim uses bland messages such as
    "Administrative prohibition" when it rejects SMTP commands for policy
    reasons. Many sysadmins like this because it gives away little information
    to spammers. However, some other syadmins who are applying strict checking
    policies want to give out much fuller information about failures. Setting
    smtp_return_error_details true causes Exim to be more forthcoming. For
    example, instead of "Administrative prohibition", you might get:


      550-Rejected after DATA: '>' missing at end of address:
      550 failing address in "From" header is: <user@???
