@argeus99 00_update.sql adds new fields and keys to some database tables, without which some API functions will not work. Load requests to Navicat/HeidiSQL and execute them one by one, ignoring queries with errors (because you already have these keys).
I execute queries from 00_update.sql on clean DB from previous version of API. All queries are completed without any errors: https://i.imgur.com/0Qiv3aD.png
You must complete these queries only once. Re-execution will result in an error. I did not write a script or migration algo to automate this procedure, because it is a very simple operation to understand.
