# Significant Changes
## TaskInstance ``priority_weight`` is capped in 32-bit signed integer ranges (#43611)
Some database engines are limited to 32-bit integer values. As some users reported errors in
weight rolled-over to negative values, we decided to cap the value to the 32-bit integer. Even
if internally in python smaller or larger values to 64 bit are supported, ``priority_weight`` is
capped and only storing values from -2147483648 to 2147483647.
