The Google Places Search API is now considered to be legacy, see Places Api Docs.

Are there any plans to integrate the new Google Places API?

Here it says that there is no new version of Find Place (Legacy). Text Search (New) has replaced it.

A different API has to be enabled in the Google Cloud Console. To save costs it is recommended to switch from legacy to new at the beginning of a month. So I think that the legacy and the new one have to co-exist for a while.
