The additional processing method has been expanded to take the owner name of the record, as HTTPS and SVBC need it to process "." in service form. The additional section callback can now return the RRset that was added. We use this when adding CNAMEs. Previously, the recursion would stop if it detected that a record you added already exists. With CNAMEs this rule doesn't work, as you ultimately care about the RRset at the target of the CNAME and not the presence of the CNAME itself. Returning the record allows the caller to restart with the target name. As CNAMEs can form loops, loop protection was added. As HTTPS and SVBC can produce infinite chains, we prevent this by tracking recursion depth and stopping if we go too deep.
