Hello, I have several DSL queries in version 7 of elasticsearch but I updated to version 8 but the queries are not working for me, I was looking at a query and in version 7 the eventtime is written like this but in version 8 the field has to be like this eventTime, I couldn't find how to know which fields are what changed from one version to another version.

I have no idea about the fields you are talking about.  
I don't believe that your question is related to the QueryDSL but may be to the mappings on related projects, like beats...

Could you specify what you are talking about?
