2022/Feb/08 ANNOUNCEMENT

Recently Implemented Changes (Currently Enabled)

As part of Upsolver's effort to adopt industry standards, we are gradually changing functions to be more Presto compatible. The functions that changed are CONCAT, SPLIT and DATE_DIFF.

CONCAT, SPLIT and DATE_DIFF are being deprecated. Henceforth, SQLs that attempt to use CONCAT, SPLIT and DATE_DIFF will include a warning message when executed. This behavior is designed to draw attention to the changes. Currently running outputs are NOT affected by these changes.

The change log summary:

Important: All information in this table, including planned versions and dates, is subject to change; the information is provided only as a guideline for updates you may make in the future.
