# 13.174. Release 0.89

## DATE Type

The memory representation of dates is now the number of days since January 1, 1970 using a 32-bit signed integer.

Note

This is a backwards incompatible change with the previous date representation, so if you have written a connector, you will need to update your code before deploying this release.

## General Changes

• USE CATALOG and USE SCHEMA have been replaced with USE.
• Fix issue where SELECT NULL incorrectly returns 0 rows.
• Fix rare condition where JOIN queries could produce incorrect results.
• Fix issue where UNION queries involving complex types would fail during planning.
