# Release 0.144.6#

## General Changes#

This release fixes several problems with large and negative intervals.

• Fix parsing of negative interval literals. Previously, the sign of each field was treated independently instead of applying to the entire interval value. For example, the literal INTERVAL '-2-3' YEAR TO MONTH was interpreted as a negative interval of 21 months rather than 27 months (positive 3 months was added to negative 24 months).

• Fix handling of INTERVAL DAY TO SECOND type in REST API. Previously, intervals greater than 2,147,483,647 milliseconds (about 24 days) were returned as the wrong value.

• Fix handling of INTERVAL YEAR TO MONTH type. Previously, intervals greater than 2,147,483,647 months were returned as the wrong value from the REST API and parsed incorrectly when specified as a literal.

• Fix formatting of negative intervals in REST API. Previously, negative intervals had a negative sign before each component and could not be parsed.

• Fix formatting of negative intervals in JDBC PrestoInterval classes.

Note

Older versions of the JDBC driver will misinterpret most negative intervals from new servers. Make sure to update the JDBC driver along with the server.
