Current behavior

Using a ProgressBar component with the why-did-you-update development package enabled I got a lot of warnings:

ProgressBar.props: Value did not change. Avoidable re-render!
Before: {mode: "indeterminate", showValue: true, value: "Loading styles", id: null, unit: "%", …}
After: {mode: "indeterminate", showValue: true, value: "Loading styles", id: null, unit: "%", …}

Expected behavior

Skip avoidable re-renders, probably switching to PureComponent would be enough.

NOTE: not sure if this is a change that can affects other primereact components too.
