Query result is different when using legacy API vs. new API

Hi @johan28,

Thanks for testing our new API :slight_smile:

This is correct; the legacy API is frozen on database version v2020.09.08, and will be indefinitely. The new API is currently running on database version v2021.11.10, which incorporates various fixes and new data. See the get_db_version() method for how to retrieve the database version via code and the Materials Project Database Release Log for more information on historical versions.

Hope this helps,

Matt
