- Sequence Version
- The sequence version appeared on the NI line in Release 47 (it did not exist before this time), with the format 'd' or 'e' or 'g' followed by digits (e.g. d12235345). This format was superseded by the SV line in Release 57, with the current format (e.g. AA123456.1). Queries are converted to uppercase by default, so users should tick the "case sensitive" box when querying by NI.
